70(10/100)=7 broken cookies.
7/70=1/10 is the fraction broken
(70-7)/70=63/70 is the fraction remaining whole
Answer:
(a) 1/7 are broken
(b) 6/7 remain whole
Step-by-step explanation:
70 is a nice number to deal with in terms of percentages and fractions. If 10% of the cookies are broken, do 10/70. That fraction simplified gets you 1/7. To find the remaining whole cookies. Do 7/7 - 1/7 = 6/7 (or if you already know that in your head that works too)

Q: A baseball is hit into the air by the Blue Jays' batting coach.
It's height h, in meters, after t seconds is h = - 4.9t² + 27.44t + 0.584
(a) write the equation in vertex form by completing the square
b) How high off the ground was the ball when it was hit?
c) When does the ball reach it's maximum height? what is it's maximum height?
d) For how long is the ball in the air ? Round answer to 1 decimal place
The ball is in the air for approximately 2.8 + √7 seconds, which rounds to 5.2 seconds when rounded to one decimal place.To write the equation in vertex form, we need to complete the square.
The given equation is h = -4.9t² + 27.44t + 0.584. We can rewrite it as:
h = -4.9(t² - 5.6t) + 0.584
Now, we want to complete the square inside the parentheses. To do this, we need to add and subtract the square of half the coefficient of t. In this case, the coefficient is -5.6, so we have:
h = -4.9(t² - 5.6t + (5.6/2)² - (5.6/2)²) + 0.584
Simplifying, we get:
h = -4.9((t - 2.8)² - 2.8²) + 0.584
Expanding further:
h = -4.9(t - 2.8)² + 4.9(2.8)² + 0.584
Thus, the equation in vertex form is: h = -4.9(t - 2.8)² + 34.328
b) The ball's height when it was hit can be found by evaluating the equation at t = 0:
h = -4.9(0 - 2.8)² + 34.328
h = -4.9(-2.8)² + 4.328
h = -4.9(7.84) + 34.328
h ≈ 0.784 meters
To find the time at which the ball reaches its maximum height, we can use the fact that the maximum height occurs at the vertex of the parabolic equation. The vertex of a parabola in the form h = a(t - h₀)² + k is given by (h₀, k). Comparing this to our equation, we can see that the vertex occurs at t = 2.8 and h = 34.328. Therefore, the ball reaches its maximum height at 2.8 seconds, and the maximum height is 34.328 meters.
The total time the ball is in the air can be determined by finding the time it takes for the ball to reach the ground. When the ball hits the ground, its height is 0. To find this time, we can set the equation equal to 0 and solve for t:
0 = -4.9(t - 2.8)² + 34.328
4.9(t - 2.8)² = 34.328
(t - 2.8)² ≈ 7
t - 2.8 ≈ ±√7
t ≈ 2.8 ± √7
Since time cannot be negative in this context, we can ignore the negative value.

The meer-kitty survey feedback tab has limitations in its data. The survey results must have at least 120 unique responses to be considered useful and aligned with the business objective. The current data, however, only has 40 total responses, with 11 of them coming from one user. This skews the results and makes it difficult to accurately analyze the feedback.
To address these limitations, it is recommended to remove the duplicates, in this case the 11 responses from one user, and focus on the remaining 29 unique responses. This will provide a clearer picture of the survey results and a more accurate representation of the feedback. By doing so, the analysis of the data will be better aligned with the original business objective and provide more valuable insights.
It is important to consider the limitations of the data when conducting any type of analysis, especially when it comes to surveys and feedback.

(Acceptance Sampling.) The following two acceptance rules are being con- sidered for determining whether to take the delivery of a large shipment of components: Rule 1. A random sample of ten components is checked, and the shipment is accepted only if none of them is defective. Rule 2. A random sample of twenty components is checked, and the ship- ment is accepted only if not more than one of them is defective. Which of these acceptance rules has the smaller probability of accepting a shipment containing 20% defectives?
we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.
How to find Probability of acceptance?To compare the probabilities of acceptance of a shipment containing 20% defectives for the two rules, we can calculate the probabilities for both rules and compare the results.
Ac coding to data:For Rule 1, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 defectives in a sample of 10 components. This can be calculated as
P(Accept | 20% defectives) = (0.8)¹⁰
= 0.107374
For Rule 2, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 or 1 defectives in a sample of 20 components. This can be calculated as:
P(Accept | 20% defectives) = (0.8)²⁰ + ²⁰C₁ * (0.8)¹⁹ * (0.2)
= 0.276
Comparing the two probabilities, we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.

it's easy it's called Two-way tables please help
Answer: The filled out table is shown below in the attached image
===========================================================
Explanation:
The letters A through J are one way to fill out the table. Though there are other possible orders.
Start at letter A, which is from the fact we have 40 people total
Then move to letter B. This is the total number who like pasta (26)
We have C = A-B = 40-26 = 14 people who don't like pasta
--------------
Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.
F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.
Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.
----------------
So we have these values
A = 40B = 26C = 14D = 21E = 19F = 4G = 17H = 9 J = 10Roy is a veterinarian at the small-animal clinic. He has 4 appointmentsscheduled for Monday Morning two new-patient appointments, a serious injury visitand a dental sealing in hours, how muchtime should these appointments take.Sick Animal visit 1/2 hrNew patient Appts : 3/4 hrSerious injury visit 1 1/4 hrdental scaling 3/4 hrImmunizations 1/4 hrRoutine physical 1/3 hr
So we have to find how much time those 4 appointments will take. Since the duration of each appointment is given in fractions it's important to remember a properties of fractions:
\(\begin{gathered} \frac{b}{a}+\frac{c}{a}=\frac{b+c}{a} \\ 1=\frac{a}{a} \end{gathered}\)It is also important to remember the relation between the mix number notation and the usual fraction number notation:
\(a\text{ }\frac{b}{c}=a+\frac{b}{c}\)With all of this in mind we can start working on the question. The four appointments consist of two 3/4 hr new patient visits, one 1 1/4 hr serious injury visit and one 3/4 hr dental sealing. The time it will take Roy to finish all of them (t) is equal to the sum of their individual times:
\(t=\frac{3}{4}+\frac{3}{4}+1\text{ }\frac{1}{4}+\frac{3}{4}\)Using what we saw about mix number notation and fractions we get:
\(\begin{gathered} 1\text{ }\frac{1}{4}=1+\frac{1}{4} \\ 1+\frac{1}{4}=\frac{4}{4}+\frac{1}{4}=\frac{4+1}{4}=\frac{5}{4} \\ 1\text{ }\frac{1}{4}=\frac{5}{4} \end{gathered}\)Then we have:
\(t=\frac{3}{4}+\frac{3}{4}+\frac{5}{4}+\frac{3}{4}=\frac{3+3+5+3}{4}=\frac{14}{4}=\frac{7}{2}\)So the answer is 7/2 hours.

I need help with this and i dont know how to do it
Answer:

Step-by-step explanation:
In general, you plot the solution to an inequality by placing a dot at the bound, then extending a line in the direction indicated by the inequality.
If the inequality symbol is < or >, the dot will be an open circle.
If the inequality symbol is ≤ or ≥, the dot will be a solid dot. That is the kind of dot needed here.
The boundary (dot) location for x ≥ -8 is at -8 on the number line. The inequality indicates that values of x greater than that are in the solution set, so the line will be shaded to the right of the dot.
The boundary (dot) location for x ≤ -2 is at -2 on the number line. The inequality indicates that values of x less than that are in the solution set, so the line will be shaded to the left of this dot.
Since the values of x must satisfy both inequalities (the conjunction is "and"), the solution set is where the lines overlap—between -8 and -2 on the number line.

Additional comment
I find it useful to write inequalities with the "arrow" pointing to the left. Here, the inequalities would be written ...
-8 ≤ x and x ≤ -2
Note that x is in the middle when the far left number is less than the far right number. (-8 < -2). That means, the inequality can be written as the compound ...
-8 ≤ x ≤ -2
When the inequalities are written in this way, with arrow(s) pointing left, the location of the variable relative to the constant is the location of the shaded line relative to the dot representing the constant. Here, the appearance of ...
-8 ≤ x ≤ -2
effectively shows you that the number line is shaded between solid dots at -8 and -2.
consider applying critical-word first and early restart on l2 cache misses. assume a 1 mb l2 cache with 64 bytes blocks. with critical-word first, it takes 100 cycles to get the first 8-byte word. otherwise, the time to receive the first 8 bytes from the memory is 90 cycles. each additional 8 bytes from the main memory require 10 cycles. if no early restart, then any word is only accessible after the block is fully fetched. further assume that the probability of referencing the first word (64-bit wide) in a block is 30% while the rest are referenced with equal probability.
The average access time for a cache miss is decreased from 61 cycles to 116 cycles by using critical-word first and early restart, which is a considerable improvement.
Critical-word first and early restart are two approaches we can employ to enhance the L2 cache's performance.
The first word in the cache block is accessed first when using the critical-word first strategy to reduce latency. In our scenario, getting the first 8-byte word requires 100 cycles. So, to speed up access when a cache miss occurs, the critical word should be fetched first.
The number of blocks in the cache can be determined using the formula below, assuming a 1 MB L2 cache with 64-byte blocks:
1 MB = 1024 * 1024 bytes
Number of blocks = 1 MB / 64 bytes = 16384
The first 8 bytes from memory must be retrieved in 90 cycles, and each subsequent 8 bytes must be retrieved in 10 cycles. The duration needed to fetch the complete block therefore is:
Time to fetch block = 90 cycles + 7 * 10 cycles = 160 cycles
Now, With the critical-word first and early restart, let's compute the average access time for a cache miss with and without these features.
Without critical-word first and early restart:
The probability of referencing the first word in a block is 30%.
The probability of referencing the remaining words in a block is (1 - 0.3) / 7 = 0.1.
So, When a cache miss occurs without using critical-word first and an early restart, the average access time is:
Average access time = probability of referencing first word * time to fetch critical word + probability of referencing remaining words * time to fetch block
= 0.3 * 90 cycles + 0.1 * 160 cycles
= 45 cycles + 16 cycles
= 61 cycles
With critical-word first and early restart:
The essential word is retrieved first, which requires 100 cycles.
As soon as the required data is made available, we begin accessing it.
In the background, the remaining words in the block are fetched.
With critical-word first and an early restart, the average access time for a cache miss is as follows:
Average access time = time to fetch critical word + probability of referencing remaining words * time to fetch block
= 100 cycles + 0.1 * 160 cycles
= 100 cycles + 16 cycles
= 116 cycles
Therefore, The average access time for a cache miss is decreased from 61 cycles to 116 cycles by using critical-word first and early restart, which is a considerable improvement.

Elsa, Chau, and Felipe served a total of 100 orders Monday at the school cafeteria. Chau served 3 times as many orders as Felipe. Felipe served 5 more orders than Elsa. How many orders did they each serve?
Answer:
Chau served 63 orders.
Elsa served 16 orders.
Felipe served 21 orders.
Step-by-step explanation:
Given information:
Elsa, Chau, and Felipe served a total of 100 orders.Chau served 3 times as many orders as Felipe. Felipe served 5 more orders than Elsa.Define the variables:
Let e = number of ordered Elsa served.Let c = number of ordered Chau served.Let f = number of ordered Felipe served.Create a system of equations from the given information and defined variables:
\(\begin{cases}e+c+f=100\\c=3f\\e=f-5\end{cases}\)
Substitute the second and third equations into the first equation and solve for f:
\(\implies e+c+f=100\)
\(\implies (f-5)+3f+f=100\)
\(\implies 5f-5=100\)
\(\implies 5f=105\)
\(\implies f=21\)
Substitute the found value of f into the second equation and solve for c:
\(\implies c=3f\)
\(\implies c=3(21)\)
\(\implies c=63\)
Substitute the found value of f into the third equation and solve for e:
\(\implies e=f-5\)
\(\implies e=21-5\)
\(\implies e=16\)
Therefore:
Chau served 63 orders.Elsa served 16 orders.Felipe served 21 orders.Let us assume that,
→ Elsa = x
→ Felipe = x + 5
→ Chau = 3x + 15
Now the required value of x,
→ x + x + 5 + 3x + 15 = 100
→ 5x + 20 = 100
→ 5x = 100 - 20
→ x = 80/5
→ [ x = 16 ]
Then the orders each serve is,
→ Elsa = x = 16
→ Felipe = x + 5 = 16 + 5 = 21
→ Chau = 3x + 15 = 48 + 15 = 63
Hence, the above one is correct.

Each chair requires 4 hours of labor, 16 feet of wood, and 0.4 gallons of stain. Each table requires 2 hours of labor, 32 feet of wood, and 0.5 gallons of stain. Each week, the company has 700 hours of labor, 3360 feet of wood, and 60 gallons of stain. The company makes $10 in profit per bar stool, $25 in profit per chair, and $35 in profit per table. In order to maximize their profit, the furniture company should make
In the given problem, the furniture company should produce 300 bar stools and 50 chairs to maximize their profit, and should not produce any tables.
How to solve the Problem?To maximize profit, the furniture company needs to determine how many units of each product (bar stools, chairs, and tables) they should produce. Let's use x, y, and z to represent the number of bar stools, chairs, and tables respectively.
The objective function to maximize profit is:
Profit = 10x + 25y + 35z
The company has constraints on the amount of labor, wood, and stain available. These constraints can be expressed as follows:
Labor: 1x + 4y + 2z ≤ 700 (the company has 700 hours of labor available each week)
Wood: 8x + 16y + 32z ≤ 3360 (the company has 3360 feet of wood available each week)
Stain: 0.2x + 0.4y + 0.5z ≤ 60 (the company has 60 gallons of stain available each week)
Also, since we cannot produce negative units of any product, we must add the constraint that x, y, and z are all non-negative.
x ≥ 0, y ≥ 0, z ≥ 0
We can now use linear programming techniques to solve this problem. One possible method is the simplex method, which involves converting the problem into an augmented matrix and applying row operations until we obtain the optimal solution.
The optimal solution is:
x = 300 (produce 300 bar stools)
y = 50 (produce 50 chairs)
z = 0 (do not produce any tables)
The maximum profit that the company can earn is:
Profit = 10x + 25y + 35z = 10(300) + 25(50) + 35(0) = $3,250

simplify [Xn (X'nY)]'.
Answer:
(X'U'Y) + (XUY')
Step-by-step explanation:
Starting with [Xn(X'nY)]', we can use De Morgan's laws to simplify the expression:
[Xn(X'nY)]' = (Xn)' + (X'nY)'
Recall that Xn represents the logical operator "and", while X' represents "not X". Using these definitions, we can expand the expression:
(Xn)' + (X'nY)' = (X'U'Y) + (XUY')
where U represents the logical operator "or".
Therefore, [Xn(X'nY)]' simplifies to (X'U'Y) + (XUY').
