Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599
The value of the limit expression
is 9, and it means that the function approaches 9, as x approaches 3.
<h3>How to evaluate the limit?</h3>
The limit expression is given as:

This means that we determine the value of the function as x approaches 3.
So, we have:
Limit = √(3^2 + 7) + 5
Evaluate the square
Limit = √(9 + 7) + 5
Evaluate the sum
Limit = √16 + 5
Evaluate the square root
Limit = 4 + 5
Evaluate the sum
Limit = 9
Hence, the value of the limit
is 9

Answer:
a what??? I'm dumb so can u plz say it in a different way?? or.....
Answer: R: 29.4, G: 0, B: 51, or #3F00FF.
I just took the pre-SAT. I thought it was going to be harder than it actually was. When I took it, it took 3 hours. The first part was reading passages and answer questions about it. That was 1 hour. The next part is on grammar. You look at sentences and figure out if they used the right set of words or punctuation. That was 45 min. The 3rd and 4th part was on math. On the third part there was like 12 multiple choice questions and like 4 problems you had to work out. The fourth part had like 21 multiple questions. and 4 problems you had to work out.
