nika2105 [10]

This is a pretty basic multiplication problem.

If one box has 789 pieces of paper in it and there are 25 boxes, you will simply multiply 789 x 25

789 x 25 = 19,725.

This shows that there are 19,725 pieces of paper in the 25 boxes of paper.

The salary of teachers in a particular school district is normally distributed with a mean of $50,000 and a standard deviation o
andrey2020 [161]

Answer:

D. 54,900

Step-by-step explanation:

We have been given that the salary of teachers in a particular school district is normally distributed with a mean of $50,000 and a standard deviation of $2,500.

To solve our given problem, we need to find the sample score using z-score formula and normal distribution table.

First of all, we will find z-score corresponding to probability 0.975(1-0.025) using normal distribution table.  

From normal distribution table, we get z-score corresponding is 1.96.

Now, we will use z-score formula to find sample score as:

z=\frac{x-\mu}{\sigma}, where,

z = Z-score,

z = Sample score,

\mu = Mean,

\sigma = Standard deviation

1.96=\frac{x-50,000}{2,500}

1.96*2,500=\frac{x-50,000}{2,500}*2,500

4900=x-50,000

4900+50,000=x-50,000+50,000

54900=x

Therefore, the salary of $54900 divides the teachers into one group that gets a raise and one that doesn't.

quester [9]
Amount of students x  Amount of buses 
= 32 x 6 
= 192 [students]

You need 192 seats since there are 192 students. To find how many rows you need you divide 192 by 8 which gives you 24
 
24 rows of seats are needed for the students
