Answer:
5?
Step-by-step explanation:
Answers B, C, D are all correct!
If a cheetah ran 196m is 8 seconds, then 196/8 = 24.5 meters per second.
Let’s verify all answers:
A) 24.5 x 6 = 147. 147m are ran in 6 seconds, not 125.
B) 24.5 x 10 = 245. This answer is correct!
C) We’ve establishes that a Cheetah ran 24.5 meters per second. Correct!
D) Since one minute equals 60 seconds, 24.5 x 60 = 1470. Correct!
E) 24.5 x 5 = 122.5. In this time frame, a cheetah wouldn’t run 125m.
Step-by-step explanation: it would help to compare whitch the answer would be 5 to 7
Answer:
1) equation is set up to determine when the cost of printing at home is the same as the cost of printing at the office
2) p = 500 means that, at printing 500 pages, the costs of home versus office printing are the same

Step-by-step explanation:
From the question we are told that
The sample size is n = 15
The difference in population proportion is 
Generally the sample mean of the input temperature is

=> 
=> 
Generally the sample mean of the output temperature is

=> 
=> 
Generally the difference of the sample mean of the input temperature and that of the output temperature is

=> 
=> 
Generally the standard deviation is mathematically represented as

=> ![s_d = \sqrt{\frac{([57.6- 65.1]- 6.6)^2+ ([68.9 - 74.4]- 6.6)^2 + \cdots + ([60.4 - 67.3]- 6.6)^2 }{15} }](https://tex.z-dn.net/?f=s_d%20%20%3D%20%20%5Csqrt%7B%5Cfrac%7B%28%5B57.6-%2065.1%5D-%206.6%29%5E2%2B%20%28%5B68.9%20-%2074.4%5D-%206.6%29%5E2%20%2B%20%5Ccdots%20%2B%20%20%28%5B60.4%20-%20%2067.3%5D-%206.6%29%5E2%20%7D%7B15%7D%20%7D)

Generally the degree of freedom is mathematically represented as

=> 
=> 
Generally the probability of t obtained from the t - distribution table at a degree of freedom of
is

Generally the p-value is mathematically represented as

=> 
=> 
From the values obtained we see that
hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
The cooling system changes the temperature of the water by 6 degrees.
