A x.+ 2 it’s a I got it right on my quiz
Answer:
0.24315
Step-by-step explanation:
Using the z score formula to solve this question
z = (x - μ) / σ,
Such that:
x = raw score
μ = population mean
σ = population standard deviation.
From the question:
x = 3000
μ = 3550
σ = 870
z = (3000 - 3550) / 870
z = -550/870
z = -0.6962
Using the z score table as well as probability calculator(as requested in the question to find the z score)
The probability of having less than 3000 is obtained as:
P(x<3000) = 0.24315
Answer:
4/5
Step-by-step explanation:
You look to where the line would meet a point on the graph ( you need 2) then you find rise over run or the y/x difference
Since it says m1 is 120 and it says find m3 don’t you need to multiply or I’m wrong
Answer:
9y= -9-2x
y=-(2/9)x-1
