Answer:
A. Fail to reject the claim that the average math SAT score is 498 when in fact it is not 498.
Step-by-step explanation:
Type II Error:
A type II error happens when there is a non-rejection of a false null hypothesis.
In this question:
The null hypothesis is H0:μ=498.
Since there is a type II error, there was a failure to reject the claim that the average math SAT score is 498 when in fact it is not 498, and thus, the correct answer is given by option A.
The cruising speed of the airplane is equal to 200 m/s.
<u>Given the following data:</u>
- Time =
![\frac{1}{12} \;minute](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B12%7D%20%5C%3Bminute)
To calculate the cruising speed of the airplane:
<h3>What is speed?</h3>
Speed can be defined as the distance covered by a physical object per unit of time. Thus, speed can be measured as meter per seconds.
Mathematically, speed is given by this formula;
![Speed = \frac{distance}{time} ](https://tex.z-dn.net/?f=Speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D%0A%0A%0A)
<u>Conversion:</u>
Distance = 1 kilometer = 1000 meter
Time = ![\frac{1}{12} \times 60 = 5\;seconds](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B12%7D%20%5Ctimes%2060%20%3D%205%5C%3Bseconds)
Substituting the given parameters into the formula, we have;
![Speed =\frac{1000}{5}](https://tex.z-dn.net/?f=Speed%20%3D%5Cfrac%7B1000%7D%7B5%7D%20)
Speed = 200 m/s.

Answer:
length = 22
Width = 17
Step-by-step explanation:
78 = 2(w+5) + 2(w)
78 = 2w + 10 + 2w
78 = 4w + 10
68 = 4w
w = 17
l = 17 + 5 = 22
The product of 3 and 7 is 21
