Answer:

[tex]y=-\dfrac{300}{7}x+1000[/tex]

Step-by-step explanation:

Method 1  (see attachment 1 with red line)

Plots the points on a graph and draw a line of best fit, remembering to ensure the same number of points are above and below the line.

Use the two end-points of the line of best fit to find the slope:

[tex]\textsf{let}\:(x_1,y_1)=(0,1000)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(7,700)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{700-1000}{7-0}=-\dfrac{300}{7}[/tex]

Input the found slope and point (0, 1000) into point-slope form of a linear equation to determine the equation of the line of best fit:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-1000=-\dfrac{300}{7}(x-0)[/tex]

[tex]\implies y=-\dfrac{300}{7}x+1000[/tex]

Method 2  (see attachment 2 with blue line)

If you aren't able to plot the points, you should be able to see that the general trend is that as x increases, y decreases.  Therefore, take the first and last points in the table and use these to find the slope:

[tex]\textsf{let}\:(x_1,y_1)=(1,940)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(7,710)[/tex]

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{710-940}{7-1}=-\dfrac{115}{3}[/tex]

Input the found slope and point (1, 940) into point-slope form of a linear equation to determine the equation of the line of best fit:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-940=-\dfrac{115}{3}(x-1)[/tex]

[tex]\implies y=-\dfrac{115}{3}x+\dfrac{2935}{3}[/tex]

Answer:

C

Step-by-step explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 4² = 9²

x² + 16 = 81 ( subtract 16 from both sides )

x² = 65 ( take square root of both sides )

x = [tex]\sqrt{65}[/tex]

Answer:

To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x. The point will be (x, 0).

Answer:

A Bar graph is most appropriate for this example

There are 3 cards and only 1 card is off.

If you pick the odd card first and do not replace it there is no chance of picking a second odd card.

The probability would be 0

Answer:

It's the fourth answer, D.

The value of the P(2 < X ≤ 4) is 0.14 if the probability of P(x =3) is 0.10 and P(x = 4) is 0.04.

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have a probability distribution shown in the table:

P(2 < X ≤ 4)

We have to find the probability between 2 and 4

P(2 < X ≤ 4) = P(x =3) + P(x = 4)

From the table

P(x =3) = 0.10

P(x = 4) = 0.04

P(2 < X ≤ 4) = 0.10 + 0.04 = 0.14

Thus, the value of the P(2 < X ≤ 4) is 0.14 if the probability of P(x =3) is 0.10 and P(x = 4) is 0.04.

Answer:

Mean=49 pounds

Median=11pounds

Step-by-step explanation:

If all the cats got weighted (5, 11,11,12,10) for each cat you need to add, multiply and divide to get all the answers (P.S. you don't need to round for your answers!)

For solving the Mean you need to add up all the numbers and then divide by how many numbers there are (5+11+11+12+10÷ 5=49)

For solving the Median you need to put the numbers in smallest to biggest order to solve for this (5,10,11,11,12) and then kept crossing them out (left to right) until you get the two middle numbers (11,11) then add them both right and then divide 22 by 2 then you have your answer!

You're going to rock this:)

Equation:

f(x) = (x + 3)^2

Graph: see image

Step-by-step explanation:

Translation just means shift or slide. To show a LEFT shift in the equation, go in close to the x, inside the parenthesis with the x, for LEFT shift, insert +3.

Left and right shifts might be the opposite of what you may think. Minus a number shifts right and plus a number shifts left.

For the graph, see image. The answer is the green curve.

Answer:

25.12 inches

Step-by-step explanation:

Given that,

→ Diameter = 8 in

→ Radius (r) = 8/2 = 4 in

→ π = 3.14

Formula we use,

→ 2πr

Then the circle's circumference is,

→ 2πr

→ 2 × 3.14 × 4

→ 2 × 12.56

→ [ 25.12 in ]

Thus, circle's circumference is 25.12 in.

We are given the statement that, If P is any odd number, then P + 2 is a prime number and we need to prove it either false or true, so as here it is written "any", so it means that the statement should be true for every and each odd number

⇒ P + 2 = 3 ↔ True

⇒ P  + 2 = 5 ↔ True

⇒  P + 2 = 7 ↔ True

⇒ P + 2 = 9 ↔ False

The given statement becomes false for P = 7, so the given statement is false
