The answer to Question 5 would be C. (-2,-1.5)

Explanation:

$\frac{2-6}{2} , \frac{7-10}{2}$

$\frac{-4}{2},\frac{-3}{2}$ so you divide the top number with the bottom number and you would get (-2,-1.5)

The answer to Question 6 would be 17 (I'm assuming they want the distance between A and B)

So you'll need to use the distance formula (which will be here somewhere) to help you to understand better

<h3>Expanation on how I got 17 for an answer:</h3>

$\sqrt{(2-(-6))}^{2}+(5-(-10))^2\\= \sqrt{64+225} \\=\sqrt{289} \\ so you square root that and get 17= 17$

Hope this helped you <3

A line passes through (10,-1) and has a slope of -1/2 whats the equation of the line

8090 [49]

Answer:

Y=-1/2x+4

Step-by-step explanation:

-The slope is -1/2 so you just plug it in where the slope would go with an x in front

-all you need now is your y-intercept which can be found by plugging in the provided info to your basic form y=mx+b

-You can take the provided point at (10,-1) and work out what the intercepts is

-1=-1/2(10)-b

-1=-5-b

4=b

You helped organize a birthday party for twenty kids. You filled 150 water balloons and the kids smashed 4/5 of them in ten minu

notka56 [123]

Answer:

Step-by-step explanation:

Okay, to find the number of balloons left over, disregard the number of kids and focus only on 150 balloons and that only 4/5 were "smashed." Multiply 150 by 4/5 to find the amount of balloons used, which is 120, and find the difference between 150 and 120, which is 30.

Pleaseeee help with this question prove (1-cos^2A)csc^2A=1

Marysya12 [62]

For all x,

sin²(x) + cos²(x) = 1

so we have

(1 - cos²A) csc²A = sin²A csc²A

and since csc(x) = 1 / sin(x), so the expression reduces to 1.

The probability distribution for a

pishuonlain [190]

Note: The values in the table are not correct because the sum of the probability of all events is not equal to one. The should be 0.13 and 0.33 instead of 0.113 and 0.133 respectively.

Given:

The probability distribution for a random variable x is given in the table.

x : -5 -3 -2 0 2 3

P(x) : 0.17 0.13 0.33 0.16 0.11 0.10

To find:

The probability of -2.

Solution:

From the given probability distribution for a random variable x, it is clear that the value of the probability is 0.33 corresponding to -2.

$P(-2)=0.33$

Therefore, the probability of -2 is 0.33.
