A study gathers data on the outside temperature during the winter, in degrees Fahrenheit, and the amount of natural gas a household consumes, in cubic feet per day. Call the temperature x and gas consumption y. The house is heated with gas, so x helps explain y. The least-squares regression line is yhat = 1344 – 19x. 1. On a day when the temperature is 20F, the regression line predicts that gas used will be about

Answers

Answer 1

Answer:

The answer is "964 cubic-feet".

Step-by-step explanation:

Given regression equation:

[tex]\to Y = 1344 - 19X\\\\\to X= 20 \ F[/tex]

Putting the value of x into the above equation:

[tex]\to Y = 1344-19\times20\\\\[/tex]

        [tex]= 1344-380\\\\= 964 \ cubic-feet[/tex]

Answer:

l = 6.00

Step-by-step explanation:

So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so

3l = 2l + 2(3), so l = 6.

what is the slant height of a pyramid with surface area of 209 square centimeters and a square base with sides of 7 centimeters? round to the nearest tenth.​

Answers

Answer:

Step-by-step explanation:

base b = 7

slant height = L

area of base = 49 cm²

lateral area = surface area - base area = 209 - 49 = 160 cm²

area of one lateral face = 160/4 = 40 cm²

½·b·L = 40

L = 80/7 ≅ 11.4 cm

Answers

Answer:

Step-by-step explanation:

Given

x² + 5x + 6

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)

The factors are + 3 and + 2 , since

3 × 2 = + 6 and + 3 + 2 = + 5 , then

x² + 5x + 6 = (x + 3)(x + 2) ← in factored form

Match each diagram with a description and an equation.

Answers

Graphs such as line and tape diagrams can be used to represent equations.

The equation of the first diagram is y = 0.6x,and it represents a decrease by 0.4 or 2/5The equation of the second diagram is y = 1.83x,and it represents an increase of 5/11 or 0.83

Diagram (a)

In this diagram, all the x boxes (5 boxes) are shaded, while all the y boxes (3) are shaded.

So, the equation is:

[tex]y = \frac{3}{5}x[/tex]

Express as decimal

[tex]y = 0.6x[/tex]

The ratio (0.6) is less than 1.

So, it represents a decrement.

And the decrement (d) is:

[tex]d = 1 - 0.6[/tex]

[tex]d =0.4[/tex]

Diagram (b)

In this diagram, all the x boxes (6 boxes) are shaded, while part of  the y boxes (6 of the 11) are shaded.

So, the equation is:

[tex]y = \frac{11}{6}x[/tex]

Express as decimal

[tex]y = 1.83x[/tex]

The ratio (1.83) is greater than 1.

So, it represents an increment.

And the increment (d) is:

[tex]d = 1.83 - 1[/tex]

[tex]d = 0.83[/tex]

A. Rectangle

Step-by-step explanation:

Shown in the attachment are the four points graphed on a coordinate plane.

We can see that the opposite sides are parallel to each other and have the same length.

The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.

The answer cannot be C. Rhombus because of the same reason as above.

The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.

Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.

Answers

Answer:

The shorter leg, which is opposite to the 30- degree angle, is labeled as x. The hypotenuse, which is opposite to the 90-degree angle, is twice the shorter leg length (2x). The longer leg, which is opposite to the 60-degree angle, is equal to the shorter leg's product and the square root of three (x√3).

Step-by-step explanation:

In any 30-60-90 triangle, the shortest leg is across from the 30° angle, the length of the hypotenuse is always double the length of the shortest leg.
