Galilea is putting a border around her Science Fair display board. How many inches of border does she need?

When they work 8 hours, both Jonny and Clara will be paid the same amount of $140.

Let's represent the number of hours worked as 'x'

Total earnings for the first job = (Hourly wage * Number of hours worked) + Bonus

= (10 * x) + 60

Total earnings for the second job = (Hourly wage * Number of hours worked) + Bonus

= (15 * x) + 20

To find the number of hours at which they will be paid the same amount, we can set the two equations equal to each other and solve for 'x':

(10 * x) + 60 = (15 * x) + 20

Now, we can solve the equation:

10x + 60 = 15x + 20

60 - 20 = 15x - 10x

40 = 5x

x = 40/5

x = 8

Total earnings for the first job = (10 * 8) + 60 = $140

Total earnings for the second job = (15 * 8) + 20 = $140

Thus, when they work 8 hours, both Jonny and Clara will be paid the same amount of $140.

To use a t-test table, you need to have the calculated t-value and the degrees of freedom (df) for your data.

To use a t-test table, you need to have the calculated t-value and the degrees of freedom (df) for your data. Here are the steps to use a t-test table:

Determine the type of t-test you are performing. There are two types of t-tests: one-sample t-test and two-sample t-test.

Calculate the t-value for your data using the appropriate formula for the type of t-test you are performing.

Determine the degrees of freedom (df) for your data. The df is calculated based on the number of observations in your sample and the number of groups being compared.

Find the critical value for your t-test in the t-table. The critical value is the value of t that separates the acceptance and rejection regions for your hypothesis test. The critical value depends on the level of significance (α) and the degrees of freedom (df) for your data.

It's important to note that using a t-test table requires some knowledge of statistics and hypothesis testing. If you are not familiar with these concepts, it's best to consult with a statistician or use statistical software to perform the t-test.

Therefore, the time spent traveling at 60mph is 1.5 hours, and the time spent traveling at 80mph is 2(1.5) = 3 hours.

Time spent traveling at 60mph = 1.5 hours

Time spent traveling at 80mph = 3 hours

To calculate the distance between two locations, use the distance formula, a Pythagorean theorem application. The Pythagorean Theorem can be rewritten as d=((x 2-x 1)2+(y 2-y 1)2) to get the distance between any two points.

Let's denote the time spent traveling at 60mph as "t", then the time spent traveling at 80mph is "2t" because the second part of the trip is twice as long as the first part.

We can use the formula:

distance = speed x time

To calculate the distance traveled in each part of the trip, then we can set up the following equations:

distance traveled at 60mph = 60t

distance traveled at 80mph = 80(2t) = 160t

The total distance traveled is given as 330 miles, so we can set up the equation:

60t + 160t = 330

220t = 330

t = 1.5 hours

Therefore, the time spent traveling at 60mph is 1.5 hours, and the time spent traveling at 80mph is 2(1.5) = 3 hours.

Time spent traveling at 60mph = 1.5 hours

Time spent traveling at 80mph = 3 hours

There are 7 oak trees and 4 maple trees in the community park, so the ratio of oak trees to maple trees can be written as 7:4.

What is ratio?

A ratio is a way of comparing two or more quantities. It is a way of expressing the relationship between two numbers in terms of their size. A ratio can be written in different ways, such as in the form of a fraction, as a decimal, or as a whole number.

We can also write the ratio in different ways, such as:

7/4 = 1.75 oak trees for every 1 maple tree

35:20 = 35 oak trees for every 20 maple trees

14:8 = 14 oak trees for every 8 maple trees

All of these ratios represent the same proportion, which is 7 oak trees to 4 maple trees.

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

x - $300

Step-by-step explanation:

Granville should plant an additional 50 trees beyond the initial 60 trees to maximize the total yield.

To determine the number of trees Granville should plant to maximize the total yield, we need to find the point where the marginal yield equals zero.

This is the point where adding an additional tree will not increase the total yield.

Let x be the number of additional trees planted beyond the initial 60 trees. Then, the average yield per tree can be represented by the equation:

y = 400 - 4x

The total yield can be represented by:

T = xy = x(400 - 4x)

Expanding this equation gives:

T = 400x - 4x^2

To find the maximum total yield, we need to find the value of x that maximizes this equation. We can do this by taking the derivative of T with respect to x and setting it equal to zero:

dT/dx = 400 - 8x = 0

Solving for x gives:

x = 50

Answer: 4.5 pounds

Explanation: To convert 72 ounces into pounds, we use the conversion factor for ounces and pounds which is 16 ounces = 1 pound.

Next, notice that we're going from a smaller unit, ounces, to a larger unit, pounds and when we go from a smaller unit to a larger unit, we divide. So here, we divide 72 by the conversion factor, 16, to get 4.5.

So 72 ounces equals 4.5 pounds.

The required simple interest of 10% of four year on principle amount is $857.

Simple interest depends on the chief measure of a credit or the first store in quite a while account. Straightforward interest doesn't build, and that implies a loan boss will just compensation interest on the chief sum and a borrower couldn't have ever to pay more interest on the recently gathered interest.

We have,

Amount of four year = $1200

simple interest = 10%

Let loaned amount is x

Then,

interest of four year =×4 x×10/100 = 4x/10

According,

x + 4x/10 = $1200

14x/10 = $1200

x = $12000/14

X = $857 (appox)

Answer:

There is a non-removable discontinuity at x = 3

Step-by-step explanation:

We are  given that

\(f(x)=\frac{x^2+9}{x-3}\)

We have to find true statement about given function.

\(\lim_{x\rightarrow 3}f(x)=\lim_{x\rightarrow 3}\frac{x^2+9}{x-3}\)

=\(\infty\)

It is not removable discontinuity.

x-3=0

x=3

The function f(x) is not define at x=3. Therefore, the function f(x) is continuous for all real numbers except x=3.

Therefore, x=3 is non- removable discontinuity of function f(x).

Hence, option B is correct.

a. The mean is 26.5, and the standard deviation is 1.154, b. The null hypothesis (H₀) and alternative would state that mean is greater , c- critical value approach is 2.997.

In the above problem given ,

Data: 28, 27, 25, 26, 28, 26, 29, 25

a. Mean:

Mean = (28 + 27 + 25 + 26 + 28 + 26 + 29 + 25) / 8 = 26.5 thousand miles

Standard Deviation:

Calculate the deviation of each value from the mean:

(28 - 26.5), (27 - 26.5), (25 - 26.5), (26 - 26.5), (28 - 26.5), (26 - 26.5), (29 - 26.5), (25 - 26.5)

Calculate the squared deviation of each value:

(28 - 26.5)², (27 - 26.5)², (25 - 26.5)², (26 - 26.5)², (28 - 26.5)², (26 - 26.5)², (29 - 26.5)², (25 - 26.5)²

Calculate the sum of squared deviations:

Sum = (28 - 26.5)² + (27 - 26.5)² + (25 - 26.5)² + (26 - 26.5)² + (28 - 26.5)² + (26 - 26.5)² + (29 - 26.5)² + (25 - 26.5)²

Divide the sum of squared deviations by (n-1), where n is the sample size:

Standard Deviation = √(Sum / (n-1)) = 1.154.

b. Null Hypothesis (H₀): The mean life expectancy of the new tires is 26,000 miles.

Alternative Hypothesis (H₁): The mean life expectancy of the new tires is greater than 26,000 miles.

c. Critical Value Approach:

With a sample size of 8, degrees of freedom (df) = n - 1 = 8 - 1 = 7. From the t-distribution table at a significance level of 0.01 and df = 7, the critical value is approximately 2.997.

Calculate the test statistic t:

t = (Sample Mean - Population Mean) / (Standard Deviation / √n)

d. P-value Approach:

To repeat the test using the p-value approach, we calculate the p-value associated with the test statistic. If the p-value is less than the significance level (0.01), we reject the null hypothesis.

Calculate the t-value using the same formula as in c.

Calculate the p-value using the t-distribution with (n-1) degrees of freedom.
