In what ways does algebra act as a tool to improve communication? How does algebra affect how people can learn from each other?

Andreyy89

Answer: Algebra acts as a tool to improve communication because much like learning a new language, you have to take baby steps before you can fully get it. This can improve communication because you're learning something new with the help of others.

Which shows the line 3x-2y=-18 in slope intercept form?

Anuta_ua [19.1K]

Hello,

The answer is A or y= 3/2x+9

How to solve;

The formula: Y=mx+b

Now solve the problem: 3x-2y=-18

Subtract -3x from both sides.

Now we have -2y=-3x-18

So divide both sides by y to get y by it self.

-2/-2=-3x-18/-2

Simplify and the answer is y=3/2x+9

Thus answer A

Hope that helps have a great day.

Answer:

3/4

Step-by-step explanation:

Scale factor is the ratio between two different triangles. They can be scaled if they are similar triangles, which they are (in this case). Since we know that these two triangles are similar, we want to match all the sides up in a way where they all have the same ratio.
NK=3 and AH = 4, so NK/AH = 3/4.
GK=6 and LH = 8, so GK/LH = 6/8 = 3/4.
GN = 15 and LA = 20, so GN/LA = 15/20 = 3/4.
We found the matching ratios, so the answer is 3/4.

In the Fuel Economy Guide for 2018 model vehicles, the Environmental Protection Agency gives data on 1160 vehicles. There are a

Natasha2012 [34]

Answer:

a) The probability is the p-value of $Z = \frac{X - 22.6}{5.2}$ , in which X is the gas mileage of the 2020 Honda Civic.

b) Your dad's truck is 1.65 standard deviations below the mean.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normal with mean 22.6 miles per gallon (mpg) and standard deviation 5.2 mpg.

This means that $\mu = 22.6, \sigma = 5.2$

a. What proportion of vehicles have worse gas mileage than the 2020 Honda Civic?

This is the p-value of Z, given by:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{X - 22.6}{5.2}$

In which X is the gas mileage of the 2020 Honda Civic.

b. My dad has a truck that gets around 14 mpg. How many standard deviations from the mean is my dad's truck?

This is Z when X = 14. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{14 - 22.6}{5.2}$

$Z = -1.65$

Your dad's truck is 1.65 standard deviations below the mean.
