Hey there!

The slope of the given line is -2

We can solve this by doing rise over run. Pick a point and see how much it goes up (positive number) or down (negative number) - numerator - and put it over the number it goes left (negative number) or right (positive number) - denominator. For example, in this situation, we can start at the point (2, -1), and we can see that we go up 2 and left 1, until we get to the next point (1, 1). Therefore, our fraction would be $\frac{2}{-1}$ , or -2.

Hope it helps and have a great day!

Answer:

See step by step

Step-by-step explanation:

For A. use any two factors that multiply to 100 that isn't 25 and 4.

For b Use one obtuse angle (angle over 90 degree) and two acute angles. Make sure they add up to 180.

For c Use any two values that add up to 52 since they didnt establish y as the midpoint.

For d. measure of angle 1 is 45 and measure of angle 2 is 45 degrees

(a) An angle measures 43 . What is the measure of its complement? (b) An angle measures 81 . What is the measure of its suppleme

vampirchik [111]

To solve the problem shown above, you must follow the proccedure shown below:

1. By definition, Completary angles are those angles whose sum is 90 degrees and Suplementary angles are those angles whose sum is 180 degrees.

2. Keeping the information above on mind, you have:
<span>
(a) An angle measures 43 . What is the measure of its complement?

=90°-43°
=47°

(b) An angle measures 81 . What is the measure of its supplement?
</span>
=180°-81°
=99°

The answers are:

a) 47°
b) 99°

1044 fans join a club in the first month after the first month nine new members are allowed to join each month how many members

laiz [17]

Answer:

Total number of members in month 34 is 1341 members.

Step-by-step explanation:

We have given,

Number of fans join a club in first month = 1044

And after the first month nine new members are allowed to join each month.

After first month , Let the number of club members in x months will be given as:

Number of members = 1044 + 9x

We need to find number of members in month 34.

So for first month we already had 1044 members, that mean for remaining 33 months we need to calculate members.

i.e total number of members in month 34 = 1044 + (33×9 ) , {Since x = 33 here}

OR total number of members in month 34 = 1044 + 297 = 1341 members

The weight of an adult swan is normally distributed with a mean of 26 pounds and a standard deviation of 7.2 pounds. A farmer ra

Snezhnost [94]

Let $X$ denote the random variable for the weight of a swan. Then each swan in the sample of 36 selected by the farmer can be assigned a weight denoted by $X_1,\ldots,X_{36}$ , each independently and identically distributed with distribution $X_i\sim\mathcal N(26,7.2)$ .

You want to find

$\mathbb P(X_1+\cdots+X_{36}>1000)=\mathbb P\left(\displaystyle\sum_{i=1}^{36}X_i>1000\right)$

Note that the left side is 36 times the average of the weights of the swans in the sample, i.e. the probability above is equivalent to

$\mathbb P\left(36\displaystyle\sum_{i=1}^{36}\frac{X_i}{36}>1000\right)=\mathbb P\left(\overline X>\dfrac{1000}{36}\right)$

Recall that if $X\sim\mathcal N(\mu,\sigma)$ , then the sampling distribution $\overline X=\displaystyle\sum_{i=1}^n\frac{X_i}n\sim\mathcal N\left(\mu,\dfrac\sigma{\sqrt n}\right)$ with $n$ being the size of the sample.

Transforming to the standard normal distribution, you have

$Z=\dfrac{\overline X-\mu_{\overline X}}{\sigma_{\overline X}}=\sqrt n\dfrac{\overline X-\mu}{\sigma}$

so that in this case,

$Z=6\dfrac{\overline X-26}{7.2}$

and the probability is equivalent to

$\mathbb P\left(\overline X>\dfrac{1000}{36}\right)=\mathbb P\left(6\dfrac{\overline X-26}{7.2}>6\dfrac{\frac{1000}{36}-26}{7.2}\right)$
$=\mathbb P(Z>1.481)\approx0.0693$
