Kelsey's lst 5 history test scores were 78 85 91 81 and 78. if her sixth test score is an 85 which of the following statements are true?

Answer: 24 miles

Step-by-step explanation:

0.5 inches : 6 miles

Form a porportion

0.5             2

___ =         ___

6                    x

0.5x= 12

12÷0.5= 24

Answer:

32

Step-by-step explanation:

If the question is x (standing for an unknown number) divided by 4 equals 8, then 8 times 4 should equal that unknown number.

x / 4 = 8

x / 4 (*4) = 8 (*4)

x = 32

We now can replace x with our number and see if this answer is valid.

x / 4 = 8

32 / 4 = 8

And yes, it is true. Therefore, 32 divided by 4 is 8.

I hope this helps! Have a lovely day!! :)

Answer:

3) Parabola

4) [tex]y = 5x^2 + 7[/tex]   and   [tex]y = \frac{10}{x} +20[/tex]

Answer:

Step-by-step explanation:

3. A parabola (view that attached graph)

4.

b. y = 5x² + 7

e. y = 10/x + 20

Hope this helps!

x is the horizontal

y is the vertical.

Therefore, Q is (0, -1)

Answer:

52 Winners

Step-by-step explanation:

Answer:

Step-by-step explanation:

Givens

The horizontal flat box has dimensions of

h = 2

w = 7

l = 21

The vertical box has dimensions of

h = 10

w = 7

L = 12

Formula

V = L * w * h

Solution

Horizontal Flat Box = L*w * h

Horizontal Flat Box = 21 * 7 * 2

Horizontal Flat Box =                                           294

Vertical Box

Vertical Box = L * w * h

Vertical Box = 12*7 * 10

Vertical Box =                                                      840

Answer:

44 in.

Step-by-step explanation:

pi = 3.14 (in our case)

circumference = diameter x pi

circ. = 14 x 3.14, which equals to 43.96

round that and you get 44 in.

Answer:

113.1 m^3

Step-by-step explanation:

Formula

volume = (4/3) * π * r³

1.33 * 3.14 * 3^3

Answer:

Part A-      Surface area = 150cm squared

Step-by-step explanation:

First you find the area of one side of the cube-

side length (5) x side length (5) = area (25)

25 is the area of one side of the cube.

Then you multiple the area of one side (25) by the amount of sides that there are (6)-

25 x 6 = 150

Answer:

D.

Step-by-step explanation:

Because since there are 4 people with an equal chance to win then you just put the number of people that you're trying to figure out over the total number.

Answer:

d

Step-by-step explanation:

Answer:

I can try to answer.

Step-by-step explanation:

1. 23

2. 25

3. week 4 is 29, and week 3 is 23

29-23=6

4. week 5 and 7 because on week 4 it was 29, it dropped to 25 on week 5. On week 6 it was 37, then dropped to 34 on week 7.

Im not rlly sure about 5, but ill answer it if I figure it out.

Answer:

c)12

Step-by-step explanation:

since on the bar graph 12 occurs the most that is the mode so hope this helps!

The mode of the daily data is 12 cups.

A skewed distribution is a distribution having bias on one of the two sides (either left or right).

It is like leaning mountain on one side (left or right).

A left skewed graph have elongated tail on the left side of the main mountain like figure. The mountain like figure is after that elongated tail. It is also called negatively skewed graph. This graph usually has mean < median < mode.

A right skewed graph has elongated tail on the right side of the main mountain like figure. The mountain like figure is before that elongated tail. It is also called positively skewed graph. This graph usually has:

Mode < median < mean.

We are given that;

The bar graph show 8cups on monday, 12 cups on tuesday, 10 cups on wednesday, 16 cups on thrusday, 12 cups on friday, 14 cups on saturday and 18 cups on sunday.

Now,

The mode of a set of data is the value that occurs most frequently.

Looking at the bar graph, we can see that the values 8, 10, 12, 14, 16, and 18 all occur once, but only one value occurs more than once, which is 12 cups on Tuesday and Friday.

Therefore, by skewed distribution the answer will be 12.

Answer: No

Step-by-step explanation:

Is 1/4 (8y -12) equivalent to 2y - 12? No. 1/4 (8y-12) equals out to 2y-3 not 2y-12. To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

Here

Answer:

31/6

Step-by-step explanation:

36/4=9

6x-22= 9

6x= 9+22

substitute 6x=31= 31/6

Answer:

x = 31/6

Step-by-step explanation:

first lets isolate the equation which equals, 6x-24+2 = 9

I got 9 from 36/4, divide top and bottom by 4 = 9

Next add the numbers, 6x -24+24= 9 turns into 6x-22= 9

Now move the -22 to the side the 9 is, 6x= 9+22

and now we can solve and substitute, 6x=31, which gives us 31/6
