Answer:
Step-by-step explanation:
point-slope equation looks like y-y1 = m(x-x1)
plug in the given point for x and y.... and the slope for m
y-9 = 3/2(x-6)
y-9 = 3/2x - 9
y = 3/2x
Answer:
The answer is x=16 so whatever the equations should look like it should be this:
Step-by-step explanation: 5(x-12)=20 5x-60=20 add 60 to 20 and get 5x=80 x=16
Answer:
D: The slope is 3, and the y-intercept is 3/2
Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
