angle A = angle B corresponding angles
8x - 8 = 5x + 25
3x = 33
x = 11
angle B
5x + 25
55 + 25
80°
The answer is: "7/10" .

Complete Question
The reading speed of second grade students in a large city is approximately normal, with a mean of 90 words per minute (wpm) and a standard deviation of 10 wpm.
What is the probability that a random sample of 12 second grade students from the city in a mean reading rate of more than 96 words per minute?
Answer:
Step-by-step explanation:
From the question we are told that:
Sample size
Sample mean
Standard Deviation
Generally
Generally the equation for P(\=x >96 ) is mathematically given by
The answer is 5. y-y1=m(x-x1) where m is the slope
Step-by-step explanation:
5x+15-10x=40 collect like terms
5x-10x=40-15. Subtract
-5x=25 divide both side by 5
x=-5.
