Bar over decimal means repeating
Answer: 106
Step-by-step explanation:
First, we can subtract 182.90 from 750, and then divide the answer by 5.35.
750 - 182.90 = 567.10. Mrs. Canale's class still needs to earn 567.10 dollars.
Now we can divide 567.10 by 5.35 to find how many frozen pizzas the class has to sell.
567.10 / 5.35 = 106.
Therefore, Mrs. Canale's class will still need to sell 106 frozen pizzas to meet their $750 goal.

Answer:
57,001 cm², or 5.7 square meters
Step-by-step explanation:
The surface area of a cylinder is given by the formula ...
A = 2πr(r +h)
A = 2π(14 cm)(14 cm +40 cm) = 1512π cm²
Then 12 cylinders will have an area of ...
12 × 1512π cm² = 18,144π cm² ≈ 57,001 cm²
Rui Feng wants to paint a total surface area of 57,001 cm², about 5.7 square meters.

The probability that a transmission will last less than 14 years is 5%
Step-by-step explanation:
Given
Mean = 16 years
SD = 1.2 years
We have to find the probability that a transmission will last less than 14 years
First of all we have to find the z-score of the value
Z-score is given by:

We will use the z-score table to find the probability of being less than 14
So,
From z-score table we get the value for -1.6666
P(z = -1.666) = 0.04846
Converting into percentage
= 0.04846* 100
= 4.846
Rounding off to nearest percentage
5%
Hence,
The probability that a transmission will last less than 14 years is 5%
