You need to calculate the z-scores for (3.0 - 1.7) years and (3.0 + 1.7) years.
Then you use a standard normal distribution table to calculate the required probability.
The formula for finding the z-score is
<span>z=<span><span>X−μ</span>σ</span></span>
Answer:
angle B, angle A, angle C
Step-by-step explanation:
< a and <c are congruent - true
<c and <b are complementary - false
<b and <c are supplementary - false
<a and <c are complementary - true
<a and <b are supplementary - false
Hope this helps! :)
Answer: 4y + 24
Step-by-step explanation: In this problem, the 4 distributes
through the parentheses, multiplying by each of the terms inside.
So we have 4(y) + 4(6) which simplifies to 4y + 24.
Answer;
4 or more tubes or paint.
Step-by-step explanation:
54- 8.50x > 20
-54 -54
-8.50x > -34
now you have to divide by -8.50 on both sides to get x alone.
-8.50x/-8.50 > -34/-8.50
x=4
