Answer:

B. The graph rises on the left side.

Step-by-step explanation:

The limit provided on the image is interpreted as; The limit of the function f(x) as x approaches negative infinity is infinity.

X is approaching negative infinity, this means that along the x-axis we are moving towards the left where the values of x become increasingly negative.

On the other hand, f(x) is approaching positive infinity, meaning that along the y-axis we are moving upwards where the values of y become increasingly positive.

This typically implies that as we move towards the left the graph of f(x) is moving upwards or basically the graph rises on the left side.

1 Solve 8x - 9 = 15 for x.

Anna [14]

Answer:

x= 3

Step-by-step explanation:

8x - 9 =15

+9 on both sides

8x = 15 + 9

Add 15 and 9 to get 24

8x = 14

Divide 8 by both sides

x = 3

An agency that hires out clerical workers claims its workers can type, on average, at least 60 words per minute (wpmwpm). To tes

lapo4ka [179]

Answer:

The right answer is:

If the mean typing speed of workers from the agency is 60 wpmwpm, the probability of selecting a sample of 50 workers with mean 58.8 wpmwpm or less is 0.267.

Step-by-step explanation:

The P-value gives us the probability of getting the sample we are evaluating (in this case a sample with size n=50 and mean=58.8 wpm), if the null hypothesis is true (in this case, μ=60 wpm).

If the P-value is low enough, that is under the significance level, then we can infer that the mean that the null hypothesis states is not the actual mean, and we have evidence to reject the null hypothesis.

Albert Abbasi, VP of Operations at Ingleside International Bank, is evaluating the service level provided to walk-in customers.

In-s [12.5K]

Answer:

The probability that Albert's sample of 64 will have a mean between 13.5 and 16.5 minutes is 0.9973.

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:

$X \sim N(\mu=15,\sigma=4)$

And let $\bar X$ represent the sample mean, the distribution for the sample mean is given by:

$\bar X \sim N(\mu,\frac{\sigma}{\sqrt{n}})$

On this case $\bar X \sim N(15,\frac{4}{\sqrt{64}})$

Solution to the problem

We are interested on this probability

$P(13.5$

If we apply the Z score formula to our probability we got this:

$P(13.5$

$=P(\frac{13.5-15}{\frac{4}{\sqrt{64}}}$

And we can find this probability on this way:

$P(-3$

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.

$P(-3$

The probability that Albert's sample of 64 will have a mean between 13.5 and 16.5 minutes is 0.9973.

the local volleyball team hosts a concession stand to raise money. They can spend $120 to purchase popcorn, candy, and drinks. t

Art [367]

To solve this question, I did an equation:
0.75x + 1.20y = 120
0.75(95) + 1.20(35) = 120
Then multiply:
71.25 + 42 = 120
Now to check:
71.25 + 42 = 113.25
Answer: 120 - 113.25 = $6.75 Hope this helps
