Answer:
Louis has faster pitch when compared to each of their teams.
Step-by-step explanation:
We have two pitchers which we need to compare to each of their teams.
To calculate this, we will approximate the distributions to a normal distribution, and calculate the z-score, to know what proportion of players of their team fall below their score.
For Jerry, he has a speed of 86 and his team has a mean speed of 93 and standard deviation of 3.
We can calculate the z-score for Jerry speed as:

The proportion of players that are below Jerry speed is approximated by the standard normal distribution:

For Louis, his speed is 84 and his team has a mean speed of 89 and standard deviation of 3.5.
We can calculate the z-score for Jerry speed as:

The proportion of players that are below Louis speed is approximated by the standard normal distribution:

As the proportion of players of Louis team that are below Louis speed is much bigger than the proportion of players of Jerry's team that are below Jerry speed, we can say that Louis has faster pitch when compared to each of their teams.
43.5 is 783 divided by 18 783 ÷ 18 = 43.5
Answer:
- 0.5
Step-by-step explanation:
you first change the fractions numbers in to decimal form
so; 2/5 = 0.4
-7/8 = - 0.875
hence; 0.4 + (-0.875)
= - 0.475
in to its simplest form = - 0.5
the answer is - 0.5
Answer:
120,000
Step-by-step explanation:
Let's say Rio gets 5x, Kim gets 7x, and Leo gets 3x. In the ratio 5:7:3:1, x = 1
5x + 7x + 3x = total = 15x
3x = 24000
divide both sides by 3 to get x
x = 8000
15x = 8000*15 = 120000
Given:
The inequality is

To find:
The solution set for the given inequality.
Solution:
We have,



Divide both sides by 3.

It can be written as

Subtracting 4 from each side, we get


The solution set of the given inequality is (-5,-3).
Therefore, the correct option is A.
