Answer:
Both of them are the same measure: 45 degrees.
Step-by-step explanation:
You plug in 15 for the xin both of the equations they give.
3(15) +17=45
75-2(15)=45
Answer:
Step-by-step explanation:
The graph of g(x), if translated upward by 1 unit, becomes the graph of h(x) = g(x) + 1.
V1 + V2
V1 = 1*2*1 = 2
V2 = 5*2*2 = 20
V1 + V2
2+20
22
Answer:
The mean is 27.8
The required variance is 23.9358
Step-by-step explanation:
Consider the provided information.
Here the random sample size, n = 200
Unemployment rate is 13.9% = p = 0.139
Part (a) expected number of grads who are unemployed.
Hence, the mean is 27.8
Part (b) variance of the random variable "number of grads who are unemployed.

Hence, the required variance is 23.9358
Answer:
(3, -3)
Step-by-step explanation:
If a point is dilated about the origin rule to be followed,
(x, y) → (kx, ky)
where k is a scale factor by which the point is being dilated.
If a point R having coordinates (1, -1) is dilated by scale factor of 3, coordinates of the image will be [3×1, 3(-1)]
Therefore, coordinates of the image R' will be (3, -3)
