Answer:
27 feet per second.
Step-by-step explanation:
You already have your time unit in second and length measurement in feet so just divide the two 378/14=27 feet per second.
Answer:
you can do it if you believe yourself
Step-by-step explanation:
Answer:
Step-by-step explanation:
<h2>Question 1: 4x + 7 + 2x</h2>
<u>Given expression</u>
4x + 7 + 2x
<u>Move like terms together</u>
= 4x + 2x + 7
= (4x + 2x) + 7
<u>Combine like terms</u>
<h2>Question 2: -4x+3y-3x+8+2y</h2>
<u>Given expression</u>
-4x + 3y - 3x + 8 + 2y
<u>Move like terms together</u>
= -4x - 3x + 3y + 2y + 8
= (-4x - 3x) + (3y + 2y) + 8
<u>Combine like terms</u>
Hope this helps!! :)

1. we know that product (x) so divide it by 2 and then minus some from 1 side and add on to the other side
Using the Empirical Rule, it is found that the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the mean of 110 and the standard deviation of 15, we have that:
These values are both the most extreme within 2 standard deviations of the mean, hence the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
