Answer:
The correct answer is D. 10.
Step-by-step explanation:
If Brandy earns 2 stars for every goal, and she scored 8 goals, then we need to multiply 8 by 2.
8 x 2 = 16
She looses 1/2 a star for every miss, and she missed the goal 12 times. Therefore, we need to multiply 1/2 by 12.
12 x 1/2 = 6
Therefore, Brandy lost 6 stars.
Now, we need to subtract the amount of stars Brandy earned by the amount that she lost.
16 - 6 = 10
Therefore, the correct answer is D. 10.
Hope this helps! :D

Answer:
Step-by-step explanation:
Distance from earth to moon =238,857 :
x-92350373 = 92589230
x= 238857
Distance from sun to moon. = 92,350,373 miles
Distance from earth to moon=184,939,603 miles
Distance from sun to moon. = 277,528,833 miles
Distance from earth to moon=238,857 miles
Distance from sun to moon. =92,828,087 miles
Answer:
The 95% confidence interval for the mean breaking weight for this type cable is (767.47 lb, 777.13 lb).
Step-by-step explanation:
Our sample size is 41
The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

Then, we need to subtract one by the confidence level
and divide by 2. So:

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 40 and 0.025 in the two-sided t-distribution table, we have 
Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

Now, we multiply T and s

Then
The lower end of the confidence interval is the mean subtracted by M. So:

The upper end of the confidence interval is the mean added to M. So:

The 95% confidence interval for the mean breaking weight for this type cable is (767.47 lb, 777.13 lb).
