Answer:(-1,-3)
Step-by-step explanation:Solve for the first variable in one of the equations, then substitute the result into the other equation.
angle of elevation, aoe = 59 deg
height, h = 40ft
distance from pole, dfp
using
tan 59deg = h/dfp
=》 dfp = h/ tan 59deg = 40/1.67 = 23.95ft
Answer: z score is -19
Work Shown:
x = 22 is the raw score
mu = 60 is the mean
sigma = 2 is the standard deviation
z = (x-mu)/sigma = formula to find z scores
z = (22 - 60)/2
z = -38/2
z = -19
The z score of -19 means we are 19 standard deviations below the mean. Anything beyond 3 standard deviations is often considered unusual/rare as most of the data in the normal distribution is within 3 standard deviations (approximately 99.7% of the distribution)
0 - (-x + 10)
a negative subtracted from something is a positive.
0 + x - 10
Your answer is x - 10

Answer:
First of all, this is a simple solution to the equation, by simplifying the equation to x greater than or equal to 12, so option A is in line with the meaning of the problem
