Answer:
The answer is 4
Explanation:
<h3><u>Given</u>;</h3>
- If 4 times a number is 48
<h3><u>To </u><u>Find</u>;</h3>
Now,
48 ÷ 4 = 12
So,
12 × 1/3 = 4
Thus, 1/3 of this number is 4

Difference between the mean of the data, including the outlier and excluding the outlier is;
B: 0.93
<h3>Mean average</h3>
Her time in minutes for the given months are;
- January = 41.55 minutes
- July = 36. 38 minutes
- Feb = 42.51 minutes
- Aug = 38.48 minutes
- Mar = 43. 01 minutes
- Sept = 41.87 minutes
- Apr = 39. 76 minutes
- Oct = 51.32 minutes
- May = 37. 32 minutes
- Nov = 42.59 minutes
- June = 35.28 minutes
- Dec = 43.71 minutes
Looking at all the numbers, they largely range from 36 to 44 which means that the outlier is 51.32
Total number of minutes with outlier = 493.78 minutes
Number of months = 12
Thus;
Mean with outlier = 493.78/12
Mean with outlier = 41.15 minutes
Mean without outlier = (493.78 - 51.32)/(12 - 1)
Mean without outlier = 40.22 minutes
Thus;
Difference in both means = 41.15 - 40.22
Difference = 0.93

Answer:
The correct answer is to compare.
For a reader to compare two or more things, the reader must consider how things are different.
Another option for the sentence could be to contrast. Compare or contrast are equally right,
A good reader needs to understand the different concepts contained in a text. If the reader does not understand the differences it would be difficult for it to have a clear idea and reach a valid conclusion. So, in order to do this, the reader has to compare ideas, propositions, theories or any other element that helps him recognize the differences.
The answer is Inirtia is the tendency of an object to resist
Answer:
A
Explanation:
You must know the basics of Trigonometry to solve this.
First, you must know that
![\frac{3\pi}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%5Cpi%7D%7B4%7D%20)
lies in the second quadrant, so sin is negative.
Next, since
pi/4, is the reference angle of 3 pi/4, this means that we can set up a right triangle with pi/4 as an angle, we get
![\cos( \frac{3\pi}{4} ) = \frac{ \sqrt{2} }{2}](https://tex.z-dn.net/?f=%20%5Ccos%28%20%5Cfrac%7B3%5Cpi%7D%7B4%7D%20%29%20%20%3D%20%20%5Cfrac%7B%20%5Csqrt%7B2%7D%20%7D%7B2%7D%20)
![\sin( \frac{\pi}{4} ) = - \frac{ \sqrt{2} }{2}](https://tex.z-dn.net/?f=%20%5Csin%28%20%5Cfrac%7B%5Cpi%7D%7B4%7D%20%29%20%20%3D%20%20-%20%20%5Cfrac%7B%20%5Csqrt%7B2%7D%20%7D%7B2%7D%20)
So the answer is A
