To find total number of girls multiply total students by the fraction of girls:
360 x 4/9 = 360 x 4 = 1440/9 = 160 total girls.
If 3/5 are below the age of ten, that means 2/5 are above the age of ten.
Multiply the total number of girls by 2/5:
160 x 2/5 = 320/5 = 64
There are 64 girls above the age of ten.
Answer:
40
Step-by-step explanation:
The two sides were shortened by 1.2 (found by dividing by the total, 60/50) so you do the same to the 48 and you get your answer.
Answer
0.975 is the probability value
Step-by-step explanation:
We start by getting the z score of 86
z-score = (x - mean)/SD
z-score = (86-98)/6 = -12/6 = -2
So we want to find the probability of z greater than or equal to 2
We shall be using the standard normal distribution table here
We have the answer as;
0.975
If you mean by x over 4 that it is fraction then there is no different between it and divisions
x/4 = -120
x = -120 × 4 ( when division goes to the other side of equal it turns into multiplication)
x = -480
A. -480
Assuming the board games are rectangular boards (which most are) you simply multiply the length with the width to get the area.
