Answer:
x/y
Step-by-step explanation:
The other person did not explain so I will:
(68+79+74)= 221/3 =73.7
80 x 4 = 320
320-221 = 99
He must get 99 on his 4th test.
Thanks
Answer:
X= 462000000
Step-by-step explanation:
I used a Calculator
Mean, mu=44 cm
standard deviation, sigma = 4 cm
X=41
We calculate the Z-value for 41 cm
Z(41)=(41-mu)/sigma=(41-44)/4=-0.75
The probability that x>X
P(x>X)
=P(x>41)
=1-P(x<41)
=1-0.2266274 (from standard normal distribution tables for left-tail of Z=-0.75)
= 0.7733726
Answer:
15/16 is already simplified
24/32 can be written as 3/4 as the numerator and denominator can both be divided by 8
