!!please help!!<br>I have an F in this class and really need to get it up!​
lisov135 [29]

I may be wrong, I think I remember how to do this. A straight line has an angle of 180, so y would be 133, making the area 55571.63u. (u = whatever unit is measuring the circle.) If x = 1/20 of the area, then the red area = 2,778.5u or 2,779u. I hope this helps, but I honestly don't remember how I would find x, and I don't want you to get the question wrong.

There are a rack of 14 billiard balls. Balls numbered 1 through 8 are solid-colored. Balls numbered 9 through 14 contain stripes
Jet001 [13]

Answer:

3/7  /    42.8% chance

Step-by-step explanation:

There are 6 striped balls (9, 10, 11, 12, 13, 14) and 8 (1, 2, 3, 4, 5, 6, 7, 8) solid colored balls. So, 6 / 14 balls are striped.

(6 / 14  = 3 / 7)

this means that the probability of a ball being striped has the odds of 3/7

(3/7 = about 42.8% chance)

Graph the image of the given triangle, translated 4 units to the right and 5 units down.
Goryan [66]

Answer- Follow the attachment attached herewith.

Solution-

As we know if we are moving in left or right, we have to deal with the x - direction or x co-ordinate and if we are moving in up and down , we have to deal with y - direction or y co-ordinate .

If we are moving in right ,we have to add in x co-ordinate and if we are moving left we have subtract from x co-ordinate. Likewise, if we are moving up, we have to add in y co-ordinate and if we are moving down, then we have to subtract from y co-ordinate.

As given in the question, we have move the triangle 4 units right and 5 units down,

The co-ordinate of given triangles'

A = (-1,3)

B = (-5,-3)

C = (2,-1)

∴Then the new co-ordinate will be

A' = (-1+4 , 3-5) = (3,-2)

B' = (-5+4 , -3-5) = (-1,-8)

C' = (2+4 , -1-5) = (6,-6)

Please help! question is in the picture!
koban [17]

9514 1404 393

Answer:

  (5, 1) or maybe (h, k)

Step-by-step explanation:

The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).

In the generic vertex form ...

  f(x) = a(x -h)² +k

the letters (h, k) are used to represent the vertex.

__

You would need to consult your curriculum materials to see what letters your author uses for the vertex in vertex form.

The table shows the time a patient spends at the dentist and the amount of the bill.
erica [24]

<u>Answer-</u>

Correlation coefficient for the data in the table was found to be 0.93.

<u>Solution-</u>

Taking the independent variable or input variable as, the time a patient spends at the dentist and the dependent variable or output variable as the amount of the bill.

We know that,

r=\frac{n(\sum xy)-\sum x \sum y}{\sqrt{[n\sum x^{2} -({\sum x})^{2}]\times [n\sum y^{2} -({\sum y})^{2}]}}


Calculating the values from the table, then putting it in the formula

r=\frac{4 \times 3130.9 \ - \ 6.45 \times 1473}{\sqrt{[4\times 12.3725 \ - \ 6.45^{2}][4 \times 877475 \ - \ 1473^2]}}

\Rightarrow r=0.929720561 \approx 0.93

∴  Correlation coefficient for the data is 0.93.
