Answer:

100

Step-by-step explanation:

She wants to average 85, so adding ALL three of her scores, divided by 3 needs to equal 85.

(75 + 80 + x)/3 = 85

Times by 3.

75 + 80 + x = 255

155 + x = 255

subtract 155.

x = 100

She needs 100 on the third test.

I'm having trouble figuring out what the equation is for the trend line and what the slope is
Talja [164]

Answer:

The equation for the trend line would be y = -1/100x + 25

Step-by-step explanation:

In order to find the trend line, we first need to find the slope. To do so, we need to find two points on the line. The points we'll use are (0, 25) and (2500, 0). Next, we use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (0 - 25)/(2500 - 5)

m = -25/2500

m = -1/100

Now that we have this we can use the slope and the intercept in slope intercept form to model the trend line.

y = mx + b

y = -1/100x + 25

A magician is performing for an audience of 32 men and 20 women. He selects a volunteer from the audience, has the volunteer sta
statuscvo [17]
32+20=52 so there are 52 people in all. 
32/52  people are men.
we now have to subtract 1 from this fraction like so 32-1/52-1 since the magician took away 1 man from the audience (therefore reducing the amount of men as well as the audience as a whole) resulting in 31/51
we multiply 32/52 with 31/51 to get 248/663. simply turn this fraction into a percent by multiplying the quotient by 100 and rounding it to the nearest tenth to get 37.4%
