Answer:
0.0478
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 135 mm
μ is the population mean = 130 mm
σ is the population standard deviation.
We are given variance = 9
Standard deviation = √variance = √9 = 3
Hence
z = 135 - 130/3
z = 1.66667
Probability value from Z-Table:
P(x<135) = 0.95221
P(x>135) = 1 - P(x<135) = 0.04779
Approximately to 4decimal places = 0.0478

Step-by-step explanation:
<u>Step 1: Define</u>
3(a - 4) ≤ 33
<u>Step 2: Solve for </u><em><u>a</u></em>
- Divide 3 on both sides: a - 4 ≤ 11
- Add 4 on both sides: a ≤ 15
Here we see that any value <em>a </em>less than or equal to 15 would work as a solution to the inequality.
There is some info missing to be able to solve.
