Answer:
The required interval is (26.23 , 27.37)
Step-by-step explanation:
The mean is = 26.8
The standard deviation is = 7.42
n = 654
At 95% confidence interval, the z score is 1.96
To find the desired interval we will calculate as:

And 
and 
= 27.37 and 26.23
So, the required interval is (26.23 , 27.37)
Remember, these are quadrilaterals, so they must add up to 360°. Just add up the angles and then do 360 minus that number to solve for x.
Therefore:
1. 118 + 90 + 99 = 307
360 - 307 = 53
2. 110 + 96 + 78 = 284
360 - 284 = 76
3. 48 + 118 + 97 = 263
360 - 263 = 97
4. 105 + 99 + 64 = 268
360 - 268 = 92
5. 103 + 63 + 113 = 279
360 - 279 = 81
6. 95 + 80 + 88 = 263
360 - 263 = 97
Answer:
She should ski on Slope B because it is steeper
Step-by-step explanation:
Slope A
We need to find the "slope"
15/24 = 5/8
Slope B
12/16 = 3/4
To compare, we need a common denominator
5/8 3/4*2/2
5/8 6/8
<
Slope B is steeper because the slope is greater
She should ski on Slope B because it is steeper
The answer is D. If you make a right triangle with the line, then you can use the Pythagorean theorem (a^2+b^2=c^2) to solve for VW. The vertical line would be 4 units and horizontal line would be 2 units. Therefore 4^2+2^2=20 take the square root of 20 and that is the answer.
Answer:

Step-by-step explanation:
As far as I am able to observe from the statement of your question, the expression is:
![\left[[\left(3^3-7\right)\cdot \frac{5}{10}\right]+\left(\left(1+3+6+9\right)-1\right)](https://tex.z-dn.net/?f=%5Cleft%5B%5B%5Cleft%283%5E3-7%5Cright%29%5Ccdot%20%5Cfrac%7B5%7D%7B10%7D%5Cright%5D%2B%5Cleft%28%5Cleft%281%2B3%2B6%2B9%5Cright%29-1%5Cright%29)
So, lets solve this expression, which anyways would clear your concept
Considering the expression
![\left[[\left(3^3-7\right)\cdot \frac{5}{10}\right]+\left(\left(1+3+6+9\right)-1\right)](https://tex.z-dn.net/?f=%5Cleft%5B%5B%5Cleft%283%5E3-7%5Cright%29%5Ccdot%20%5Cfrac%7B5%7D%7B10%7D%5Cright%5D%2B%5Cleft%28%5Cleft%281%2B3%2B6%2B9%5Cright%29-1%5Cright%29)


Lets first solve
