3 0

Answer:

There would be 12 total picks.

Step-by-step explanation:

In order to find this, create a proportional equality in which the top of the equation is the number of orange picks and the bottom is the number of green picks.

2/1 = x/4

Now we cross multiply to find out the total number of picks.

1*x = 4*2

x = 8

Now that we have the number of orange picks, we add to the number of green picks for the total number.

4 + 8 = 12

In a study of 30 high school students, researchers found a high correlation, 0.93, between amount of exercise and weight lost. W
zloy xaker [14]

Answer:

Option A is true

The researchers proved that exercise causes weight loss only for high school students.

Step-by-step explanation:

We are told that the researchers found a high correlation, 0.93, between amount of exercise and weight lost.

Now, looking at each of the options;

- A is True because due to the high correlation, the research proves that exercise causes weight loss but only for high school students.

- B is not true because we are told the correlation is very high at 0.93. Thus, it is untrue that there is no proven causation.

-C is not true because there's no where that the researchers have completely proved that exercise causes weight loss generally. It is only peculiar to the high school students studied.

-D is not true because the 93% is just a correlation and not a percentage of those who lost weight

Consider he following table. Does the table represent a function? Why or why not?
Damm [24]
This is considered a function because each input has a different output. For example, a certain x value doesnt equal 2 different y values, making this a function. Take this: if there is (2,4) and (3,4), this is a function because although the y values are the same, the x values are different. (2,3) and (2,4) do not convey a function because the x values are the same, but each has a different y value.
hope this helped!!!

On a fair, 8-sided die, each face is painted as follows: the 1 and 2 are painted green, 3 through 6 are painted blue, 7 is paint
Alinara [238K]

Answer:

0.25

Step-by-step explanation:

outcomes painted in blue: {3, 4, 5, 6}

number of even outcomes painted in blue: 2

number of total outcomes: 8

Therefore, the probability that the roll will show an even number and a face that is painted blue is: 2/8 = 0.25

17) The total cost to produce x units of paint is C(x) = (5x + 3)(7x + 4). Find the marginal
Bad White [126]

Answer:

17) MC(x) = 35 − 12/x²

18) R(x) = -0.05x² + 80x

Step-by-step explanation:

17) The marginal average cost function (MC) is the derivative of the average cost function (AC).

AC(x) = C(x) / x

MC(x) = d/dx AC(x)

First, find the average cost function:

AC(x) = C(x) / x

AC(x) = (5x + 3)(7x + 4) / x

AC(x) = (35x² + 41x + 12) / x

AC(x) = 35x + 41 + 12/x

Now find the marginal average cost function:

MC(x) = d/dx AC(x)

MC(x) = 35 − 12/x²

18) x is the demand, and p(x) is the price at that demand.  Assuming the equation is linear, let's use the points to find the slope:

m = (40 − 50) / (800 − 600)

m = -0.05

Use point-slope form to find the equation of the line:

p(x) − 50 = -0.05 (x − 600)

p(x) − 50 = -0.05x + 30

p(x) = -0.05x + 80

The revenue is the product of price and demand:

R(x) = x p(x)

R(x) = x (-0.05x + 80)

R(x) = -0.05x² + 80x
