Key info-there are nine boys for every six girls on the softball team
9/6
9(3)=27. 6(3)18
18+27=45 5 more to go
if there is 50 students on each of the teams
9(5)=45
6(8)=48
As one can see,they both cannot multiply up to 50,but they round up.
Answer:
what one
Step-by-step explanation:
if it is the left one it is -7(2x)+-7(7)+10x=-4x
Answer:25th Percentile: 5
50th Percentile: 30
75th Percentile: 34
Interquartile Range: 29
Step-by-step explanation:
Answer:
P(Z < 2.37) = 0.9911.
Step-by-step explanation:
We are given that Let z denote a random variable that has a standard normal distribution.
Let Z = a random variable
So, Z ~ Standard Normal(0, 1)
As we know that the standard normal distribution has a mean of 0 and variance equal to 1.
Z = ~ N(0,1)
where, = mean = 0
= standard deviation = 1
Now, the probability that z has a value less than 2.37 is given by = P(Z < 2.37)
P(Z < 2.37) = P(Z < ) = P(Z < 2.37) = 0.9911
The above probability is calculated by looking at the value of x = 2.37 in the z table which has an area of 0.9911.
