Answer: 95% confidence interval = 20,000 ± 2.12 $\times$ $\frac{1500}{\sqrt{17} }$

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )

Step-by-step explanation:

Given :

Sample size(n) = 17

Sample mean = 20000

Sample standard deviation = 1,500

5% confidence

∴ $\frac{\alpha}{2}$ = 0.025

Degree of freedom ( $d_{f}$ ) = n-1 = 16

∵ Critical value at ( 0.025 , 16 ) = 2.12

∴ 95% confidence interval = mean ± $Z_{c}$ $\times$ $\frac{\sigma}{\sqrt{n} }$

Critical value at 95% confidence interval = 20,000 ± 2.12 $\times$ $\frac{1500}{\sqrt{17} }$

( 19228.736 , 20771.263 ) OR ( 19229 , 20771 )

Hello!!!

Answer:

11 cups of chocolate chips

Step-by-step explanation:

If we use the information we got from the problem we can see that 8 gives us 12. So all we need to do is add more to the orignal number(8) unitll we get 15. So 11 cups gives us 15 cookies.

Answer:

The measure of the angle ABD is:

m∠ABD = 122°

Step-by-step explanation:

Given

m∠ABC = 84°

m∠CBD = 38°

To determine

Find m∠ABD

The given diagram shows that m∠ABD is the sum of m∠ABC and m∠CBD.

In other words,

m∠ABD = m∠ABC + m∠CBD

substituting m∠ABC = 84° and m∠CBD = 38°

m∠ABD = 84° + 38°

m∠ABD = 122°

Therefore, the measure of the angle ABD is:

m∠ABD = 122°
