WARRIOR [948]2 years ago

5 0

Answer:

Angle 11 is the alternate exterior of angle 5 meaning there is only 1 angle that is alternate of angle 5. Step-by-step explanation: An exterior angle is an angle outside of the shape (hence ex meaning out).

Suppose the correlation between height and weight for adults is +0.40. What proportion (or percent) of the variability in weight

Schach [20]

Answer:

We are given the correlation between height and weight for adults is 0.40.

We need to find the proportion of the variability in weight that can be explained by the relationship with height.

We know that coefficient of determination or R-square measures the proportion or percent of variability in dependent variable that can be explained by the relationship with independent variable. There the coefficient of determination is given below:

$R^{2}=r^{2}=0.40^{2}=0.16$

Therefore, the 0.16 or 16% of the variability in weight can be explained by the relationship with height

NEED HELP NEED HELP please if you know show me how you got the answer

OLEGan [10]

Answer:

It says to Graph y = 1/2x - 4

So equation y = 1/2x - 4

this corresponds to slope intercept form which is y = mx + b

M = slope = rise / run

B = y - intercept

First, start at the origin, (0,0)

Then go down 4, you should now be on the coordinate (0,4)

Now we need to use the slope.

The slope is 1 / 2, this means rise 1, run 2 (in this case 2 to the right because it is positive)

So, start at (0 , 4) and go up 1 unit then 2 to the right, then place a dot, keep repeating until you meet the end of the paper.

Then do the opposite so that you can graph the other side.

Down 1 and 2 to the left.

James wants to build a wooden barrel to hold rain water to use for irrigation. He wants the height of the barrel in feet to be 4

lina2011 [118]

Answer:

Step-by-step explanation:

To create a system of inequalities, write an inequality to model each condition that must be satisfied in the given situation.

It is given that x represents the area of the base of the barrel in square feet and y represents the volume of the pump in cubic feet.

Write an inequality to represent the amount of water that the barrel needs to hold after the pump is inserted. To find the volume of the barrel, multiply the area of the base by the height of the barrel. Then subtract the volume that will be taken up by the pump from that amount.

x(x-4) - y ≤ 90

To find the cost of the supplies for the barrel, find the surface area by multiplying the perimeter of the base by the height of the barrel and then adding the area of the base. Since there is no top, the area of the base only needs to be added once. Then, multiply the cost per square foot by the surface area.

To find the cost of the pump, multiply the cost per square foot of the pump by its volume.

Write an inequality representing the total cost. The cost must be less than or equal to $1,100.

8(x(x-4)+x) + 50y ≤ 1,100

Combining both of the inequalities gives the following system of inequalities.

x(x-4) - y ≤ 90

8(x(x-4)+x) + 50y ≤ 1,100

A^2-b^2+4b-4 please solve it step by step i will mark you brainlest

alex41 [277]

Answer:

b = a + 2 or b = 2 - a

Step-by-step explanation:

Solve for b:

-4 + a^2 + 4 b - b^2 = 0

The left hand side factors into a product with two terms:

(2 + a - b) (-2 + a + b) = 0

Split into two equations:

2 + a - b = 0 or -2 + a + b = 0

Subtract a + 2 from both sides:

-b = -a - 2 or -2 + a + b = 0

Multiply both sides by -1:

b = a + 2 or -2 + a + b = 0

Subtract a - 2 from both sides:

Answer:

b = a + 2 or b = 2 - a
