(7/10 + 1/2) * 5/8 -1/2
parenthesis first....common denominator is 10
(7/10 + 5/10) * 5/8 - 1/2
12/10 * 5/8 - 1/2...reduce when u can
6/5 * 5/8 - 1/2
now we multiply
30/40 - 1/2
3/4 - 1/2
now we subtract...common denominator is 4
3/4 - 2/4 = 1/4 <== ur answer
Standard deviation is 7.35
Mean is 84
Cindy got a 100
(100-84)/7.35=2.2
D FINAL ANSWER
Answer:
-6
Step-by-step explanation:
Let the number be x.
2x + (x-5) = x - 17
2x + x - 5 = x - 17
3x - x = -17 + 5
2x = -12
: x = -12/2
x = -6
Answer:
The volume of the new prism is 24 ft³
For standing of prisms side by side, only the length of the ne prism is increased
Step-by-step explanation:
The dimensions of the new prism are;
Length = 8 mm
Height = 3 mm
Width = 1 mm
Therefore, the volume of the of rectangular prism is given by the following expression;
Volume = Width × Height × Length = 8 × 3 × 1 = 24 ft³
Therefore, the volume of the new prism = 24 ft³
Where, the prism are arranged side by side, we have the heights and width remaining the same, while the length is increased.
Answer:
D
Step-by-step explanation:
ince the only colors are white, green, yellow, red, and purple, we can see that NOT getting red or purple is the same as GETTING white, green or yellow
So, P(NOT getting red or purple) = P(GETTING white, green or yellow)
There are 60 jellybeans in total.
Number of jellybeans that are white, green or yellow = 22 + 18 + 11 = 51
So, P(GETTING white, green or yellow) = 51/60
= 17/20
= 0.85
