Answer: feet to miles
Step-by-step explanation:
Given:
551.88 + 341.64b
The coefficient of "B" is 341.64, the best statement that applies to it is:
<span>D. It is the cost for one cable box with DVR and HD service for one year.
</span>Cable boxes: $ 3.49 per cable box
HD Service: $ 9.99 per cable box
<span>DVR: <u> $ 14.99 per cable box</u>
</span>Total : $ 28.47
multiply <u> 12 months</u>
Annual cost $341.64
<u>Answer</u>: No, we do not have sufficient evidence to conclude that the mean call duration, µ, is different from the 2010 mean of 9.4 minutes.
Step-by-step explanation:
As per given , we have
, since is two-tailed so , the test is a two tail test.
Since population standard deviation is unknown, so we use t-test.
Critical value (two-tailed) for significance level of 0.01=
For n =50 , and s= 4.8
Test statistic :
Since test statistic value (-1.18) lies in critical interval (-2.609228, 2.609228), it means the null hypothesis is failed to reject.
We do not have sufficient evidence to conclude that the mean call duration, µ, is different from the 2010 mean of 9.4 minutes.
Answer:
56x + 16
Step-by-step explanation:
To simplify the expression, we just multiply the number outside the parenthesis - 8 in this problem - by both numbers inside the parenthesis.
So,
8 * 7x = 56x
8 * 2 = 16
56x + 16 is 56x + 16.
This cannot be further simplified.
