The average rate of change between x = -3 and x = 1 is; 9/4

The average rate of change is calculated as the slope of the line between the two given points on the graph.

Now, looking at the graph, we can see that the coordinates of the two given points are;

(-3, -6) and (1, 3)

The formula to calculate the average rate of change which is the slope is;

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - (-6))/(1 - (-3))

Answer: 25% i believe

Step-by-step explanation:

The probability that it lands inside the triangle is,

P = 25%

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Since, the probability is equal to,

P = size of the event space/size of the sample space

Here, In this problem

size of the sample size = area of the rectangular dartboard = 648 square centimeters

And, size of the event space = area of the triangular part = 162 square centimeters.

Hence, the probability that it lands inside the triangle is,

P = 162 / 648

P = 0.25

P = 25%

It is true that a multiple linear regression model interprets the slope differently than a simple linear regression model.

The link between two variables is determined through simple linear regression. The slope of a straight line used to represent linear regression indicates how changing one variable impacts another variable.

For the complex relationships between data, multiple linear regression is used. More than one variable may contribute to the explanation of this relationship.

One y-intercept and numerous slopes (one for each variable) make up a multiple regression formula. The formula is understood in the same way as a simple linear regression formula, however more than one variable influences the relationship's slope.

Therefore, the statement is true.

Answer: ( -9, -8)

Step-by-step explanation:

When reflected across the y-axis, the y-coordinate will be the opposite!

So the answer is (-9, -8)

To find the slope of a line given an equation in the form of ax + by = c .The slope of 7x + y = -4 is 7.

To find the slope of a line given an equation in the form of ax + by = c, you first need to put the equation into slope-intercept form, which is y = mx + b. To do this, start by subtracting ax from both sides of the equation, leaving you with by = c - ax. Then divide both sides by b, giving you y = (c - ax) / b. This is the equation in slope-intercept form, with m being the slope, which in this case is 7.

It makes 1430 = <<1430=420>>420 shillings per trip during rush hours.

Since the matatu made 10 trips and earned 3540 shillings, then it made 10-3540/280 = <<10-3540/280=12>>12 trips during normal hours.

This means it made 10-12 = <<10-12=2>>2 trips during rush hours. Answer: {2}.

P(Z3)=0.1170 is the likelihood of earning at least 1 gram of extra cereal.A probability seems to be a number that expresses the possibility or probability that a specific event will take place.

The probability is computed by dividing the total possible outcomes by the number of possible ways the event could occur. Probabilistic and odds are two distinct ideas. Odds are the likelihood that something will occur and the variety of outcomes that can result in success. the overall number of outcomes that could occur. For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping the coin and getting heads is 1 in 2.

Y=1.8945 grams.

Y = 0.8405 grams.

Here we have to find how much a refrigerant can hold.

Data given:

outer diameter (d) = 78inch

outer radius(r) = 39 inch

inner diameter (d') = 34 inch

inner radius (r') = 17inch

Height (h) = 12 feet

= 144 inch

the formula to find the volume of the cylinder:

volume= пr²h

So here we get

Refrigerant hold = Volume of the outer cylinder - the volume of the inner cylinder

= πr²h - πr'²h

= πh(r² - r'²)

= π ×144 ( 39² - 17²)

Answer:

The average rate of change of a function over an interval is found by taking the difference between the function's values at the endpoints of the interval and dividing by the length of the interval. In this case, we have:

f(1) = -3(1)^3 + 7(1) = -3 + 7 = 4

f(3) = -3(3)^3 + 7(3) = -27 + 21 = -6

The average rate of change over the interval from x=1 to x=3 is therefore (-6 - 4) / (3 - 1) = -10 / 2 = -5.

To label your answer, you could write something like: "The average rate of change of the whale's movement over the interval from x=1 to x=3 seconds is -5 meters/second."

Explanation:

Segments JK, KL, and JL are tangent to the circle.

We can break those segments into smaller pieces and notice we have these 3 pairs of congruent tangents:

Let's use the first equation to solve for x.

MJ = NJ

5x-8 = 8x-35

5x-8x = -35+8

-3x = -27

x = -27/(-3)

x = 9

Use the same idea to find y.

KN = KO

7y-9 = 2y+11

7y-2y = 11+9

5y = 20

y = 20/5

y = 4

Now compute the length of segment KO.

KO = 2y+11 = 2*4+11 = 19 units

Subtract this from LK to find LO

LO = LK - KO

LO = 32 - 19

LO = 13

This makes segment LM to be also 13 units long.

Now use the value of x to find sides MJ and NJ

MJ = 5x-8 = 5*9-13 = 32

NJ = 32 as well

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

x = 4[tex]\sqrt{3}[/tex]

The Dimensions are 16.402 in wide by 8.401 in tail

Can the perimeters of two dissimilar shapes match each other?

Perimeter of custom windows = Perimeter of (rectangle+ semicircle)

Perimeter of rectangle = 2xy

Perimeter of semicircle = 1/2 πx²

A = 2xy + 1/2 πx²

2x + 2y + πx = 60

y = (60 - 2x -πx) / 2

A = 2x([60 - 2x - πx] /2) + 1/2(πx²)

0 = 60 - 4x - πx

x = 60 / (π+4)

x = 8.401

Synthetic division is a yet another way to divide a polynomial by the factor, where k is a constant.

What is a synthetic division?

Synthetic division is usually used to find factors of polynomials of degree 3 that cannot be factored by grouping the polynomial.

Synthetic division is also used to find factor polynomials of degree 4 or higher.

We use synthetic division if and only if no other methods will work since there is a trial and error aspect to using it.

Taking an example:

We have to find the roots of the polynomial, [tex]f(x)= x^3+3x^2-4[/tex]

Substituting x=1 in the above equation, we get,

f(1)= [tex]1^3+3-4[/tex]=0

Thus, (x-1) is a root of the above polynomial.

Dividing the given function by (x-1)

[tex]x^3+3x^2-4/x-1\\=x^2+4x+4\\=(x+2)^2[/tex]
