ST describes the perpendicular bisector of PQ.

What is the perpendicular bisector?

A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector. In other terms, a perpendicular bisector separates a line segment into two equal halves by intersecting it at a 90° angle.

Here,

We have to find which statement describes the ST.

We concluded that ST describes the perpendicular bisector of PQ.

A perpendicular bisector is a line or a segment perpendicular to a segment that passes through the midpoint of the segment.

Hence, ST describes the perpendicular bisector of PQ.

g) Non linear proportional relationship

h) Proportional linear relationship.

Proportional relationships are defined as relationships between two variables where their ratios are equivalent.

a) We are told that the y-intercept is not the origin. The equation of a line in slope intercept form is; y = mx + c

If c which is the y-intercept is not equal to zero, the this is a non-proportional linear relationship.

b) Direct variation is a proportional linear relationship because the two variables are directly related to each other.

c) y = -7x can be rewritten as; y/x = -7. Thus, this is a proportional linear relationship.

d) y = 5x + 1. As said in a  above, this is also a non-proportional linear relationship.

e) y = x. can be rewritten as; y/x = 1. Thus, this is a proportional linear relationship.

Answer:

The answer is 6, I am going to give you a explanation just in case you need one.

Step-by-step explanation:

We are going to refer seed packets as SP just to make it more simple. And flowers F this is just to make it easier on ourselves.

Ok since we know that in order to plant 9 F we need 3 SP.

If we do the equation correctly we should get

3 SP × ? = 9

In order to do this there is two ways I am going with the easier one we just have to add 3 to 3 until we get 9 ok so 3 + 3 = 6 so lets add more 3's 6 + 3 = 9 great so this means 3 + 3 + 3 = 9. Now if  you noticed he had three three's which means our equation now is

3 SP × 3 = 9

Now that we are done with the first part it should just get easier from here.

We know that each SP has 3 F to grow and each SP has 9 F to grow we just have to do 9 + 9 which gives us 18.

Therefore the answer is 2 SP needed to plant 18 flowers.

Answer: 50-35

Step-by-step explanation:

Because if you calculate it, 50x70% or 50x0.7 is 35. I multiply bt 70% not 30% because you are trying to find the amount after the 30% decrease, meaning it is 70% of the orginal value.

Answer:

50 to 35

Step-by-step explanation:

[tex]\frac{30}{27} =\frac{100}{y}[/tex]

30y = 2700

y = 90

27 is 90% of 30.

[tex]\frac{50}{35}=\frac{100}{y}[/tex]

50y = 3500

y = 70

35 is 70% of 50.

The difference between the actual value of the response variable and the corresponding predicted value(regression error) using the multiple regression model is the correct option.

A residual is a measurement of the vertical distance between a point and the regression line. It is just the discrepancy between an actual value observed and a value that was projected.

To ensure that the requirements for making conclusions about the coefficients in a linear model have been met, one should always perform a residual analysis.

In regression analysis, a residual is the discrepancy between an observed value and a predicted value.

It is determined by,

Residual = Observed value – Predicted value

The residual is the discrepancy between the expected value and the actual value.

Observed value minus predicted value equals residual.

A function from a set X to a set Y in mathematics assigns each object of X exactly one element of Y. The domain and codomain of the function are denoted by the sets X and Y, respectively.

Here,

Given:{(8, 2), (4, -1), (0, -1), (-4, 2)}

Thus , to find the domain

D={8,4,0,-4}

And to find the domain we check the last term of every bracket,{(8, 2), (4, -1), (0, -1), (-4, 2)}

What is a linear equation in one variable?

The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

The cost function is A(x) = 150 + 35x

We have to find the value of A(220), so put x  = 220 in the given cost function, we get

        A(x) = 150 + 35x

        A(220)= 150 + 35(220)

                    = 150 + 7700

Answer:

x = 8

y = 36

Step-by-step explanation:

The triangle shown in the image is an isosceles triangle.

We can find the value of x using the above mentioned information:

∠B = ∠A

5x = 40 divide both sides by 5

x = 8

The sum of interior angles in a triangle is equal to 180°.

Since ∠B and ∠C are both 40°:

40 + 40 + 3y - 8 = 180 add/subtract like terms

72 + 3y = 180 subtract 73 from both sides

3y = 108 divide both sides by 3

y = 36

What is exponential?

The exponential is an example of a mathematical function that is useful in determining if something is increasing or decreasing exponentially is the exponential function. As implied by its name, an exponential function uses exponents. But take note that an exponential function does not have a variable as its exponent and a constant as its base (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

total surgeries at hospitals is approximated by

f(x)=1314+303 Inx

A) this function predicts for the percent of outpatient surgeries in 1996 IS

x = 1996-1900 = 96.

So f(96) = -1314 + 303 ln(96) =68.99 %

b) f(x) = 60

60 = -1314 + 303 ln(x)

ln x = (1314+60)/303 = 4.53

x = 92.75.

Answer:

perimeter is 6 times as long as the width

Step-by-step explanation:

let width be w then length l = 2w

perimeter (P) of a rectangle is calculated as

P = 2(l + w )

  = 2(2w + w)

 = 2(3w)

 = 6w

Perimeter is 6 times as long as the width

The width of the rectangle is (1/6) times long as the perimeter of the rectangle.

The area of a rectangle is given by -

A{R} = Length x Breadth

A{R} = L x B

Given is the length of a rectangle is twice its width.

Assume the width of the rectangle be [x] units. Then, the length will be [2x] units. For the width of the rectangle to be as long as the perimeter of the rectangle -

{P} = 2{L + B} = 2{x + 2x} = 6x

Now -

{w} = x

So, we can write that -

{P} = 6{w}

{w} = {1/6}{P}

Therefore, the width of the rectangle is (1/6) times long as the perimeter of the rectangle.

yes, the periodic interest rate for a loan with an annual interest rate of 15.98% compounded weekly is 0.3073%

The yearly interest rate is divided by the quantity of compounding periods to produce the periodic interest rate. Interest can be earned on or added to interest more frequently when there are more compounding periods.

The interest rate that is levied on a periodic basis, such as monthly or quarterly, is known as the periodic rate. A credit card with an annual percentage rate of 18% has a periodic rate of 1.5 percent per month. The periodic rate is calculated by multiplying it by the number of periods in a year.

according to the formula :

periodic interest rate is annual interest rate divided by the number of times per year interest compounds so,
