Answer:

C. y = -2x - 1

Step-by-step explanation:

y = mx + b

The slope is going down so that means that the m will be negative.

We are left with two choices:

y = -2x - 1

y = -2x + 1

Check the graph again to find what point does the line intersect the vertical line (y-axis). That hits in (0, -1) or -1.

So the only answer applicable is option C.

pishuonlain [190]

Answer:

5 cats

Step-by-step explanation:

d/c = 5/1

d = 25 Substitute in the proportion

25/c = 5/1 Multiply both sides by c

25 = 5c/1

25 = 5c Divide each side by 5

c = 5

There are five cats.

If I understand your question correctly, you want to know how many pounds of vegetables the zoo feeds the animals a month if its a 30 day month?

In that case it would be 23 pounds times 30 days which is 690 pounds of vegetables. SO the zoo feeds the animals 690 pounds of vegetables to the animals each month.

Is that what your asking for?

A set of exam scores is normally distributed and has a mean of 80.2 and a standard deviation of 11. What is the probability that

ZanzabumX [31]

Answer:

93.32% probability that a randomly selected score will be greater than 63.7.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

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, we have that:

$\mu = 80.2, \sigma = 11$
