So to find the avrage u r going to add all the numbers then divide by the nuber of nubers u have there that will give u ur answer
Answer:
the answer is D) 5(30 - 5) + 40; 165 stars
Step-by-step explanation:
because you multiply the number of levels between Level 30 and Level 5 by 5 stars per level. Add the number of stars needed in Level 5.
5(30 - 5) + 40
5(25) + 40
165 stars
The Mean = (135 + 71 + 69 + 80 + 158 + 152 + 161 + 96 + 122 + 118 + 87 + 85 ) : 12 = 111.166
The smallest value : 69
The greatest value : 161
s² = ∑( x i - x )² / ( n - 1 )
s² = ( 568.274 + 1613.3 + 1777.97 + 971.32 + 2193.42 + 1667.4 + +2483.42 + 230 + 117.38 + 46.7 + 584 + 684.66 ) : 11
s² = 1176.1676
s = √s² = √1176.1676
s ( Standard deviation ) = 34.295
All the values fall within 2 standard deviations:
x (Mean) - 2 s and x + 2 s
Answer:1. C 3. 52
Step-by-step explanation:
Answer:
<em>The quotient is 
</em>
Step-by-step explanation:
Given expression is: 
<em>While dividing two fractions, first we need to change the division sign into multiplication and then flip the second fraction. </em>
So, we will get.....
![\frac{5}{4c^2}\div \frac{15}{7c}\\ \\ =\frac{5}{4c^2}\times \frac{7c}{15}\\ \\ =\frac{35c}{60c^2}\\ \\ = \frac{7}{12c} \ \ [Dividing\ both\ numerator\ and\ denominator\ by\ 5c]](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4c%5E2%7D%5Cdiv%20%5Cfrac%7B15%7D%7B7c%7D%5C%5C%20%5C%5C%20%3D%5Cfrac%7B5%7D%7B4c%5E2%7D%5Ctimes%20%5Cfrac%7B7c%7D%7B15%7D%5C%5C%20%5C%5C%20%3D%5Cfrac%7B35c%7D%7B60c%5E2%7D%5C%5C%20%5C%5C%20%3D%20%5Cfrac%7B7%7D%7B12c%7D%20%5C%20%5C%20%5BDividing%5C%20both%5C%20numerator%5C%20and%5C%20denominator%5C%20by%5C%205c%5D)
So, the quotient is
