Answer:42°
Step-by-step explanation:So each minute, it advances by 1/60 of a complete rotation. A complete rotation is, of course, 360° . So each minute, it advances (360°/60) = 6° . (6° / minute) x (7 minutes) = 42°
Answer:
C.4/17
Step-by-step explanation:
A proper fraction has a numerator that is less than the denominator

B. 15/2 15>2 improper
C.4/17 4 < 17 proper
D.6/6 6=6 improper
Answer:
92% Confidence Interval = [8.515, 8.605]
Step-by-step explanation:
The number of samples given is 15,this less than 30, hence, we use the t score confidence Interval
= Mean ± t score × Standard deviation/√n
Mean = 8.56 ounces
Standard deviation = 0.09 ounces
n = 15
We find the degrees of freedom = n - 1
= 15 - 1 = 14
Using the T score table
T score for 92% confidence interval with degrees of freedom 14
= 1.8875
Hence:
Confidence Interval =
= 8.56 ± 1.8875 × 0.09/√15
= 8.56 ± 0.0454010035
Confidence Interval
8.56 - 0.0454010035
= 8.5145989965
≈ 8.515
8.56 + 0.0454010035
= 8.6054010035
≈ 8.605
92% Confidence Interval = [8.515, 8.605]
Answer:
6 feet
Step-by-step explanation:
Since there are 8 bricks and each brick is 9 inches long, that is a total of 72 inches. Now, you need to convert it from inches to feet. Since 1 foot is 12 inches, we need to divide 72 by 12 to get the number of feet. 72 / 12 is equal to 6.
