-5, because when plugging the -1 in for x then multiplying it by 5, you get -5
Answer:
m∠RST = 155°
m∠RSU = 102°
Step-by-step explanation:
m∠RST = m∠RSU + m∠UST
12x - 1 = 9x - 15 + 53
12x - 9x = 1- 15 + 53
3x = 39
x = 39/3
x = 13°
m∠RST = (12x -1)° = (12 * 13 - 1)° = (156 - 1 )° = 155°
m∠RSU = (9x -15)° = (9 * 13 - 15)° = ( 117 - 15)° = 102°
Answer:
Step-by-step explanation:
Using the Pythagorean Theorem, if you take 8 and square it, you get 64.
You then take 5 and square it giving you 25.
add the 64 and 25 to get you 89 = x squared.
Then take the square roots of x. (Keep in mind, what you do to one side must be done to the other.)
Because 89 is not a perfect square, you can it it as the square root of 89.
Answer:
3
Step-by-step explanation:
(-7)-9-((-4)-1)
-2-(-4-1)=3
-2-(-5)=3
-2+5=3
x=3

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
