What is it that I am supposed to be doing?
The lowest sum would be 2 and the highest is 10
So the sums from 2 through 10 equal 9
N being the number, n-4=-21. n=-17
Answer:
(7 x 3) + p
Explanations:
The number of cars Toretto has = 7
The number of cars Brian has = 3
The product of Toretto and Brian Cars = 7 x 3
The product of Toretto and Brian Cars = 21
Rome has p cars more than the product of Toretto and Brian's cars
The expression for the number of cars Rome has will be:
Number of Rome's cars = (7 x 3) + p
which can also be simplified as 21 + p
Answer:
t ≈ 13.26
Step-by-step explanation:
We are given;
x¯ = 20 minutes per day
μ = 17 minutes per day
sample standard deviation; s = 1.6 minutes
Sample size; n = 50
When σ is unknown, formula for test statistic is;
t = (x¯ - μ)/(s/√n)
t = (20 - 17)/(1.6/√50)
t = 3/0.2263
t ≈ 13.26
