Answer:
y = 4x + 4
Step-by-step explanation:
Two points you can see on the graph are (0,4) and (-2,-4)
Now, to find the slope, use delta y/ delta x
(-4-4)/(-2-0)
(-8)/(-2) = 4
Slope is 4.
y = 4x + b
Now, to find b, we need the y-intercept, which is the point where x is 0 and the graph crosses the y-axis.
This value is 4. So, the y-intercept is 4
Substitute into your equation
y = 4x + 4
We know the full protractor measures 180 degrees.
We need to know what angle it is on. By looking at it, it looks like it is on 135.
180-135= 45
The angle is 45 <em>degrees.
I hope this helps!

ANSWER: Multiply and Divide from left to right
To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
Ummm search it up on google it should be on there
Answer:
a. 0.5
Step-by-step explanation:
We know that X follows normal distribution with
mean=75
standard deviation=8
P(0<Z<∞)
The area under the normal curve is 1 and the (0<Z<∞) =0.5 and (-∞<Z<0) =0.5
So, P(0<Z<∞)=0.5
Hence the P(X ≥ 75)=0.5
