Answer:

The correct option is C.

Step-by-step explanation:

From the given graph it is clear that the x-intercept is 8 and y-intercept is 4.

If Tabitha took 6 hours to drive to her friend’s house, then the x-intercept must be 6, which is not equal to 8.

According to the graph the Tabitha took 8 hours to drive to her friend’s house because the x-intercept is 8.

Therefore the option A is incorrect.

If Matthew used 12 gallons of gas in all, then the the x-intercept must be 12, which is not equal to 8.

According to the graph the Matthew used 12 gallons of gas in all because the x-intercept is 8.

Therefore the option B is incorrect.

Rosa will pay off her loan in the eighth month, then the the x-intercept must be 8.

Since the x-intercept of line is 0, therefore the option C is correct.

Eight members of Hoi's family were each charged $4, then the function is defined as

f(x)=4x

Here the slope of line is 4.

According to the graph the line has negative slope.

Therefore the option D is incorrect.

If f(x)= 3x^2- 4 and g(x) = 2x-6, what is g(f(2))?<br> -16<br> 0-2<br> O 8<br> 10

nexus9112 [7]

Answer:

Step-by-step explanation:

g(f(x)) = g(3x² - 4) = 2(3x² - 4) - 6

g(f(2) = 2(3*2² - 4) - 6 = 2*8 - 6 = 16 - 6 = 10

Please help! What is the line's slope??

MariettaO [177]

The slope is the rise over run. Basically, any line has a constant increase. If you are looking at a line on a graph and each point it meets at is 1 up and 1 over, the slope is 1. Say the line goes up two and over one for each time it meets an actual point, the slope would be 2. If it is 1 up and 2 over, it would be 1/2.

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below

emmasim [6.3K]

Answer:

Tera had the higher z-score, so she should be offered the job.

Step-by-step explanation:

Z- score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem:

Whoever has the higher z-score should get the job.

Brittany:

Scored 88.3, mean 63.1, standard deviation 14. So

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

$Z = \frac{88.3 - 63.1}{14}$
