<h3><u>Answer:</u></h3>

Option: D is the correct answer.

D. As x increases, y decreases and then increases.

<h3><u>Step-by-step explanation:</u></h3>

Clearly from the graph of the function we could see that as the x-value increases the y-value decreases as the graph is a line segment whose slope is negative and then it increases since the graph is again a straight line with a positive slope .

Hence, the statement that best describes the relationship between x and y is:

D. As x increases, y decreases and then increases.

Charra [1.4K]

Answer:

This is an example of a combined 45 45 90 triangle and a 60 30 90 triangle. I have put the pictures showing the side lengths.

Step-by-step explanation:

On the 30 60 90, the hypotenuse is 6.

6 = 2x

x = 3

therefore, the two legs of the triangle are measured as 3 and 3 $\sqrt3}$

Now that we have 3 $\sqrt3}$ as one of the legs for the other triangle, using the picture of the 45 45 90 triangle, the hypotenuse must be x $\sqrt{2}$ .

Since x = 3 $\sqrt3x}$ , x $\sqrt{2}$ is 3 $\sqrt3}$ x

Therefore x=3 $\sqrt{6}$

In one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the enti

jekas [21]

Answer:

$X \sim Hyp (N = 810, M=102, n=4)$

$P(X=0) = \frac{(102C0)(810-102 C 4-0)}{810C4}$

And solving we got:

$P(X=0)= \frac{(102C0) (708C4)}{810C4} = 0.583$

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583

Step-by-step explanation:

For this case we can model the variable of interest with the hypergeometric distribution. And with the info given we can do this:

$X \sim Hyp (N = 810, M=102, n=4)$

$P(X=k)= \frac{(MCk)(N-M C n-k)}{NCn}$

Where N is the population size, M is the number of success states in the population, n is the number of draws, k is the number of observed successes

And for this case we want to find the probability that none of the scales selected would be defective so we want to find this:

$P(X=0)$

And using the probability mass function we got:

$P(X=0) = \frac{(102C0)(810-102 C 4-0)}{810C4}$

And solving we got:

$P(X=0)= \frac{(102C0) (708C4)}{810C4} = 0.583$

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583

Answer:

x = 15√3

y = 30

Step-by-step explanation:

In a 30°-60°-90° "special" triangle, the ratios of side lengths are ...

1 : √3 : 2

Your diagram shows the short side is 15, so the other sides can be found by multiplying the above ratio numbers by 15.

1 : √3 : 2 = 15 : x : y = 15 : 15√3 : 30

x = 15√3

y = 30
