A _________ is used to change one unit to another?

Answers

Answer:

conversion factor

Step-by-step explanation:

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

An owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree-days, where a day's degree-days are the number of degrees its average temperature falls below 65° F) over a 23-month period. He then computed the least-squares regression line for predicting y from x and found it to be ŷ = 84 + 18x. How much, on average, does gas used increase for each additional degree-day?

Answers

Answer:

18

Step-by-step explanation:

In the linear regression equation y=a+bx, slope coefficient b represents average unit increases in y variable due to unit increase in x variable.

In the given equation ŷ = 84 + 18x, b=18 represents average unit increases in gas used due to unit increase in degree day.

Hence,on average,  gas used increase by 18 for each additional degree-day.

The graph of f(x)=2^x is shown in black (k). Match each transformation of this function with a graph below.

Answers

Answer:

Step-by-step explanation:

From the graph attached,

Black curve represents a function f(x) = 2ˣ

When this curve is reflected over the x-axis image of the function will be,

g(x) = -[tex]2^{x}[/tex] [Red curve]

Similarly, curve represented by h(x) = [tex]2^{-x}[/tex] is the blue curve [image of f(x) reflected over y-axis]

When this curve is reflected over the x-axis, image of the function will be,

h'(x) = [tex]-2^{-x}[/tex] [green curve]

[tex]-2^{x}[/tex] → Red

[tex]-2^{-x}[/tex] → Green

[tex]2^{-x}[/tex] → Blue

A right triangle has one angle that measures 5°. What is the measure of the other acute angle?

Answers

Answer:

85

Step-by-step explanation:

There are three angles in a triangle

Since it is a right triangle one angle is 90 degrees

We are given one angle is 5 degrees

Let the third angle be x

The sum of the angles of a triangle is 180

x+5+90 =180

Combine like terms

x+95 = 180

Subtract 95 from each side

X+95-95 = 180-95

x = 85

add them and you get 12z+8=224
Now take away 8 from both sides to make it 216 and divide both sides by 12 and you get 18. Now just plug in the variable so 4x18+3 which is 75. And if it is a rectangle then it will be the same on both ends.

Answer the following. (a) What happens to the median? It decreases by s[ It increases by se It stays the same. It decreases bys] (b) What happens to the mean? It increases by It stays the same. ​

Answers

Answer:

Step-by-step explanation:

Before: 545, 945, 970, 995 , 1015, 1030 , 1040 , 1124

Now:  905, 945, 970, 995 , 1015, 1030 , 1040 , 1124

a) Median stays same.

As number of data's is 8, median is the average of 4th and 5th term

Median = (995 + 1015)/2 = 2010/2  =

Median = 1005

When rent changes from $545 to $ 905, the 4th and 5th term remains same.

So, median stays same

b) Mean increases 45

Before: 545, 945, 970, 995 , 1015, 1030 , 1040 , 1124

Mean = Sum of rents ÷ 8

= (545 + 945+ 970+ 995 + 1015 +1030 + 1040 + 1124)/8

=7664/8

= 958

Now : 905, 945, 970, 995 , 1015, 1030 , 1040 , 1124

Mean = (905 + 945+ 970+ 995 + 1015 +1030 + 1040 + 1124)/8

         = 8024/8

         = 1003

Mean increases by 1003 - 958 = 45

Answers

Answer:

b. 988.97

Step-by-step explanation:

got a 100 on the test

The balance at the end of May after the minimum payment is made is

$571.64.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $628.16

r = 10.59%

n = 12

t = 1/12

The amount after March.

A = 628.16 [tex](1 + 0.1059)^{12\times0.08[/tex]

A = $633.48

Monthly payment.

= 3.96/100 x 633.48

= $25.09

Remaining amount.

= 633.48 - 25.09

= $609.39

The amount after April.

A = 609.39 [tex](1 + 0.1059)^{12\times0.08[/tex]

A = $614.55

Monthly payment.

= 3.96/100 x 614.55

= $24.34

Remaining amount.

= 614.55 - 24.34

= $590.21

The amount after May.

A = 590.21 [tex](1 + 0.1059)^{12\times0.08[/tex]

A = $595.21

Monthly payment.

= 3.96/100 x 595.21

= $23.57

Remaining amount.

= 595.21 - 23.57

= $571.64

Thus,

The balance at the end of May is $571.64.
