D: There were 100 more football players than basketball players.
Step-by-step explanation:
Distribute the 9 to each term in the parentheses with multiplication.
9(3 + x) = 27 + x
But this is usually written as x + 27
Answer:
x=0 or x=4
Step-by-step explanation:
5x(x−4)=0
Let Z be the reading on thermometer. Z follows Standard Normal distribution with mean μ =0 and standard deviation σ=1
The probability that randomly selected thermometer reads greater than 2.07 is
P(z > 2.07) = 1 -P(z < 2.07)
Using z score table to find probability below z=2.07
P(Z < 2.07) = 0.9808
P(z > 2.07) = 1- 0.9808
P(z > 2.07) = 0.0192
The probability that a randomly selected thermometer reads greater than 2.07 is 0.0192
