Using the normal distribution, the probability that x is less than 110 is:
A. 0.975.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given as follows:
The probability is the <u>p-value of Z when X = 110</u>, hence:
Z = 2
Z = 2 has a p-value of 0.975.
Hence option A is correct.

The answer is A just trust me
The function is only shifted vertically up 3 :)
To find distance between points <span>A(<span>xA</span>,<span>yA</span>)</span> and <span>B(<span>xB</span>,<span>yB</span>)</span>,
formula:
<span>d(A,B)=</span>√ [(xB−xA)^2+(yB−yA)^2]
so distance between the points: (–6, 7) and (–1, –5)<span>
</span>= √ [<span><span><span><span>(<span>−1−<span>(<span>−6</span>)</span></span>)^</span>2 </span>+ <span><span>(<span>−5−7</span>)^</span>2]

Answer:
He washed 4 cars.
Step-by-step explanation:
1. The variable that was unknown x amount of cars washed.
2.The equation I used was 110-50=15x
3. To solve this you subtract the 50$ from 110$ you get sixty dollars you do that to take out what he earned for his allowance. Then your equation is 60=15x so you divide each side by 15 and when you do that x=4
