Find how many cars she can wash in one day:

95 cars / 5 days = 19 cars per day.

Now multiply by 11 days:

19 cars per day x 11 days = 209 total cars.

Ten college students were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 a

solong [7]

Answer:

The 95% confidence interval for the true slope is (0.03985, 0.14206).

Step-by-step explanation:

For the regression equation:

$\hat y=\alpha +\hat \beta x$

The (1 - α)% confidence interval for the regression coefficient or slope $(\hat \beta )$ is:

$Ci=\hat \beta \pm t_{\alpha/2, (n-2)}\times SE(\hat \beta )$

The regression equation for current GPA (Y) of students based on their GPA's when entering the program (X) is:

$\hat Y=3.584756+0.090953 X$

The summary of the regression analysis is:

Predictor Coefficient SE t-stat p-value

Constant 3.584756 0.078183 45.85075 5.66 x 10⁻¹¹

Entering GPA 0.090953 0.022162 4.103932 0.003419

The regression coefficient and standard error are:

$\hat \beta = 0.090953\\SE (\hat \beta)=0.022162$

The critical value of t for 95% confidence level and 8 degrees of freedom is:

$t_{\alpha/2, n-2}=t_{0.05/2, 10-2}=t_{0.025, 8}=2.306$

Compute the 95% confidence interval for $(\hat \beta )$ as follows:

$CI=\hat \beta \pm t_{\alpha/2, (n-2)}\times SE(\hat \beta )\\=0.090953\pm 2.306\times 0.022162\\=0.090953\pm 0.051105572\\=(0.039847428, 0.142058572)\\\approx (0.03985, 0.14206)$

Thus, the 95% confidence interval for the true slope is (0.03985, 0.14206).

What is the length of BC in the right triangle below?

Neko [114]

Answer and Step-by-step explanation:

How to solve:

Use the Pythagorean Theorem to find the length of side BC.

Pythagorean Theorem Formula:

$A^2+B^2=C^2$

Side AB will be A, side AC will be B, and side BC will be C.

Plug in values.

$8^2+15^2 = C^2\\\\\\64 + 225 = C^2\\\\289 = C^2\\Square.root.both.sides.\\\\\sqrt{289} = C\\17 = C\\\\\\$

This means the answer is A. 17.

I hope this helps!

Will give brainliest answer

nexus9112 [7]

Answer:

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

We see that: 4.1 + 1.3 < 8.4

=> Can't form a triangle from 4.1 cm, 8.1 cm and 1.3 cm

Pluto is looking into joining a gym. He has a budget of $68 per month. The gym he wants to join has fees based on the number of

Artist 52 [7]

7(10 visits) ≤ 68
70 ≤ 68
Not Viable

7(9 visits) ≤ 68
63 ≤ 68
Viable

The first solution is not viable because 10 visits will give a total cost of $70 per month, which is $2 over his monthly budget of $68.

The second solution is viable. He could visit the gym a maximum of 9 times per month for a total of $63 a month and that will be under his $68 monthly budget.

Hope this helps! :)
