Answer:
88
Step-by-step explanation:

The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.
Solve for x:



Thus, Allen needs at least an 88 to obtain a mean of at least 90.
Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.
Answer: x = 40.81 or 41
Step-by-step explanation:
A = B = 21
C = 35
Hypotenuse = x
Calculating Hypotenuse:
21^2 + 35^2 = x^2
=> 441 + 1225 = x^2
=> x^2 = 1666
=> x = 40.81 or 41
Answer:
6 centimeters
Step-by-step explanation:
Square E'F'G'H' is just square EFGH translated to the left.
It is still the same size, just in a different location.
Line segment EF is the same length as segment E'F'.
6 centimeters
First, you find the volume of each individual cube, and then you add everything up.
1^3 +2^3+3^3+4^3 + 5^3 = 225
hope this helped :)
