1/2 (x - 10) = 7 what does x =

x = 24

Step-by-step explanation:

distibute: 1/2x - 5 = 7

add 5 to both sides: 1/2x = 12

multiply by 2 on both sides: x = 24

To check your work:

1/2[(24) - 10] = 7

simplify inside the parenthesis: 1/2[14] = 7

multiply: 7 = 7

the statement is true so your answer is corect

0.2743

Step-by-step explanation:

Given : The reading speed of second-grade students in a large city is approximately​ normal, with a mean of words per minute​ (wpm) and a standard deviation of  wpm.

Let x be the random variable that represents the reading speed of second -grade students.

z-score :

For x= 96 words per​ minute

Now, the probability a randomly selected student in the city will read more than 96 words per​ minute will be :-

Hence, the probability a randomly selected student in the city will read more than 96 words per​ minute = 0.2743
