Sally rolled a 6-sided number cube 40 times and it landed on 4 eight times. What is the experimental probability of Sally getting a 4?

Answer:

The domain of a function is the set of its possible inputs, i.e., the set of input values where for which the function is defined. In other words, the domain of f is the set of real number R (and its set of possible outputs or codomain is also the set of real numbers R)

Its negative, the sign of the sum is the sign of addend with the greatest absolute value.

12x + 2y = 25

2. Cost for each pound of almond (x) = $1.5

Cost for each pound of jelly beans (y) = $3.5

From the information given above, we can create the system of equations that will be used in solving the problem as shown below.

a. The system of equations that represents the situation is:

3x + 5y = 22 ----> equation 1

12x + 2y = 25 ----> equation 2

b. Multiply equation 1 by 2, and equation 2 by 5:

6x + 10y = 44 ----> equation 3

60x + 10y = 125 ----> equation 4

Subtract equation 4 from equation 3

-54x = -81

-54x/-54 = -81/-54

x = 1.5

Cost for each pound of almond (x) = $1.5

Substitute x = 1.5 into equation 1

3x + 5y = 22 ----> equation 1

3(1.5) + 5y = 22

4.5 + 5y = 22

5y = 22 - 4.5

5y = 17.5

5y/5 = 17.5/5

y = 3.5

Cost for each pound of jelly beans (y) = $3.5

Answer: 300 square meters

Step-by-step explanation: Since 12/6 is 2 hours we can just do 25x12 to get 300 square meters.

300 square meters.

Step-by-step explanation:

2 divided by 1/6 equals 12.

12 x 25 equals 300.

The velocity of the flow in the channel is 1.2fps

The optimum velocity in sewers is approximately 2 feet per second at peak flow, because this velocity normally prevents solids from settling from the lines; however, when the flow reaches the grit channel, the velocity should decrease to about 1 foot per second to permit the heavy inorganic solids to settle.

It takes a float 30 seconds to travel 37 feet in a grit channel.

To find the velocity of the flow in the channel.

We know the formula of velocity of the flow in the channel.

\(Velocity(fps) = \frac{distance traveled(ft)}{time required(seconds)}\)

\(Velocity(fps) = \frac{37 ft}{30 sec}=1.2 fps\)

The calculation below can be used for a single channel or tank or for multiple channels or tanks with the same dimensions and equal flow. If the flow through each unit of the unit dimensions is unequal, the velocity for each channel or tank must be computed individually.

The given question is incomplete, complete question is:

It takes a float 30 seconds to travel 37 feet in a grit channel. What is the velocity of the flow in the channel?

We can define the speed as the quotient between the distance moved, and the time it takes to move that distance, so we have:

speed = Distance/Time.

Now we can rewrite this as:

Distance = Speed*Time.

We will find that the speed of the car was 21 mi/h.

Here the information given is:

Mr. Pipkins speed is: S = 3.5 mi/h

The car needed 27 "steps" to reach the corner.

Mr. Pipkins needed 27 + 135 = 162 "steps" to reach the same corner.

Because the number of steps is related to time and distance, the ratio between the number of steps should be the same as the ratio between the speeds:

162/27 = 6

(Pipkins needed 6 tomes more steps than the car, so the car moves 6 times faster than Pipkins)

This means that the speed of the car is 6 times larger than the speed of Mr. Pipkins.

Then the speed of the car is:

S' = 6*(3.5 mi/h) = 21 mi/h.

Answer:

A, B, D, E

Step-by-step explanation:

Given expression:

When multiplying decimals, multiply as if there are no decimal points:

\(\implies 6 \times 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 5 digits.

Put the same number of total digits after the decimal point in the product:

\(\implies (0.06) \cdot (0.154)=0.00924\)

-----------------------------------------------------------------------------------------------

Answer option A

\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)

When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.

Therefore:

\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)

Therefore, this is a valid answer option.

Answer option B

\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)

Multiply the numbers 6 and 154:

\(\implies 6 \times 154 = 924\)

Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).

\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)

Therefore, this is a valid answer option.

Answer option C

\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)

Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:

\(\implies 6 \cdot 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 3 digits.

Put the same number of digits after the decimal point in the product:

\(\implies 0.924\)

Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.

Answer option D

\(\boxed{6 \cdot 154 \cdot (0.00001)}\)

Again, employing the technique of multiplying decimals.

As there are a total of 5 digits after the decimals:

\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)

Therefore, this is a valid answer option.

Answer option E

\(\boxed{0.00924}\)

As we have already calculated, (0.06) · (0.154) = 0.00924.

Therefore, this is a valid answer option.

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you move down 1 unit, you simply subtract 9 units from the given equation.

g(x) = 4x^2 - 16 - 1

g(x) = 4x^2 - 17

Shifting right is a little bit tricky. To shift right, you have to do the opposite of what you would do on the number line. The x has to become x - 9 because the x value (you will learn later) is part of a distance and distances always subtract one from the other.

The wrong way to do it is in answer A.

B is the correct answer

h(x) = 4(x - 9)^2 - 17

The solution to the given differential equation is \(y = a_0x^{[0]} + a_1x^{[1]} + a_2x^{[2]}\), where a_0, a_1, and a_2 are constants.

To fathom the given differential equation, xy'' + y' = 0, we will begin by expecting a control arrangement of the frame y = ∑(n=0 to ∞) a_nx^n, where a_n speaks to the coefficients to be decided.

Separating y with regard to x, we get:

\(y' = ∑(n=0 to ∞) a_n(nx^[(n-1))] = ∑(n=0 to ∞) na_nx^[(n-1)]\)

Separating y' with regard to x, we get:

\(y'' = ∑(n=0 to ∞) n(n-1)a_nx^[(n-2)]\)

Presently, we substitute these expressions for y and its subsidiaries into the differential condition:

\(x(∑(n=0 to ∞) n(n-1)a_nx^[(n-2))] + (∑(n=0 to ∞) na_nx^[(n-1))] =\)

After improving terms, we have:

\(∑(n=0 to ∞) n(n-1)a_nx^[(n-1)] + ∑(n=0 to ∞) na_nx^[n] =\)

Another, we compare the coefficients of like powers of x to zero, coming about in a boundless arrangement of conditions:

For n = 0: + a_0 = (condition 1)

For n = 1: + a_1 = (condition 2)

For n ≥ 2: n(n-1)a_n + na_n = (condition 3)

Disentangling condition 3, we have:

\(n^[2a]_n - n(a_n) =\)

n(n-1)a_n - na_n =

n(n-1 - 1)a_n =

(n(n-2)a_n) =

From equation 1, a_0 = 0, and from equation 2, a_1 = 0.

For n ≥ 2, we have two conceivable outcomes:

n(n-2) = 0, which gives n = or n = 2.

a_n = (minor arrangement)

So, the solution to the given differential equation is \(y = a_0x^{[0]} + a_1x^{[1]} + a_2x^{[2]}\), where a_0, a_1, and a_2 are constants.

The given null hypothesis statement a. true, statement b. true and finally statement c. true.

a. False. Rejection of the null hypothesis using ANOVA only tells us that at least one group mean is different from the others, but it doesn't necessarily mean that all means are different from each other. Additional post-hoc tests, such as Tukey's HSD or Bonferroni, are needed to identify which specific means are different from each other.

b. True. If the null hypothesis is rejected using ANOVA, it means that there is significant variability between the groups. This variability is measured by the F-statistic, which is the ratio of between-group variability to within-group variability. A high F-statistic indicates that the standardized variability between groups is higher than the standardized variability within groups.

c. True. If the null hypothesis is rejected using ANOVA, it means that there is at least one significant difference between the means of the groups. Pairwise comparisons can be conducted using post-hoc tests to identify which specific pairs of means are significantly different. However, it's important to adjust the significance level for multiple comparisons to avoid making Type I errors.
