Step-by-step explanation:

Answer:

cube a geometrical shape which is a three-dimensional figure. It has 6 faces, 12 edges and 8 vertices.

Step-by-step explanation:

GLOSSARY

Faces: The flat surfaces which are squre in shape

Vertices: Corners

Answer:

(a) The relation is a function

(b)

[tex]Domain = \{-3,2,5,8\}[/tex]

[tex]Range = \{7,5,-3,-2\}[/tex]

Step-by-step explanation:

Given

[tex]\{(-3, 7), (2, 5), (5, -3), (8, -2)\}[/tex]

(a): Is it a function?

A relation has the form: [tex]\{(x_1,y_1),(x_2,y_2)....(x_n,y_n)\}[/tex]

For the relation to be a function, all the x values must be unique and not repeated.

In [tex]\{(-3, 7), (2, 5), (5, -3), (8, -2)\}[/tex], the x values are: -3, 2, 5 and 8.

None of the values are repeated.

Hence, the relation is a function

(b): The domain and the range:

The x values represent the domain while the range are represented by the y values.

So, we have:

[tex]Domain = \{-3,2,5,8\}[/tex]

[tex]Range = \{7,5,-3,-2\}[/tex]

Answer:

Option 2

Step-by-step explanation:

Go through until you find a true statement:

- The number of observations is 10

Count the number of data points. You should end up with 15, so this option is not correct.

-The median of the data set is 10

To find the median, you know that there are a total of 15 data points, so the median would be the mean of the 7th and 8th (because those are the middle numbers). If you look at the data points, the 7th and 8th points are at 10. The mean of 10 and 10 is just 10,  so that means the median of the set is 10.

This is the correct answer.

If you want, you can also go through the other options and see that none of them work.

Answer:

The person above is correct it would be option two!

The explanation makes alot of sence. I took the test to make sure it was correct i gotten a 100~!!! ty!

Answer:

y=x-2

Step-by-step explanation:

y-y1=m(x-x1)

y-3=1(x-5)

y-3=x-5

y=x-5+3

y=x-2

Answer:

x>−7

Explanation:

Let's solve your inequality step-by-step.

−4x<28

Step 1: Divide both sides by -4.

−4x/−4 < 28/−4

x>−7

Answer: x>−7

Answer:

Explanation:

This is a ratio question. If we are comparing the ratios, we could say

24

36

=

x

2

where x = the amount of sugar to make 24 cookies.

We can multiply both sides by 2 to cancel the 2 on the right, making

24

(

)

36

=

.

Simplify this and we get

Answer:

12 feets below sea level

Step-by-step explanation:

Initial height = 25 feets above sea levwl

Total descent = 37 feets

Distance traveled below sea level = 37 feets - 25 feets = 12 feets

Hence, Sarah traveled 12 feets below sea level

Answer:

the answer will be 10 aka number 1

Step-by-step explanation:

If the left side is 18 and the number above it is half that aka 9 then the other side is 10

Answer:

4x²+4y²-20x+12y-2=0

4x²-20x+4y²+12y = 2

4(x²-5x) + 4(y²+3y) = 2

4(x²-5x+25/4) + 4(y²+3y+9/4) = 2 + 4*25/4 + 4*9/4

4(x-5/2)² + 4(y+3/2)² = 36

(x-5/2)² + (y+3/2)² = 9

Answer:

43 minutes

Step-by-step explanation:

Arrival time at grocery store = 11:19 a.m

Time spent in store = 24 minutes

Number of minutes after 11:00 a.m when she arrived and left the store :

Time she left the store :

11:19 a.m + 24 minutes = 11:43 a.m

Minutes after 11:00 when she left :

11:43 - 11:00

= 43 minutes

Step-by-step explanation:

Rotating (2,-6) 90 degrees results in (6,2)

[tex]42 \frac{5}{10} + 37 \frac{8}{10} [/tex]

[tex] \frac{5}{10} + \frac{8}{10} = \frac{13}{10} = 1 \frac{3}{10} [/tex]

Answer:

1 7/95

Step-by-step explanation:

convert the fractions into improper fractions

3 2/5 = 17/5

3 1/6 = 19/6

[tex]\frac{17}{5}[/tex] divided by [tex]\frac{19}{6}[/tex] - invert second term and multiply

so 17 * 6 = 102

5* 19 = 95

answer is 102/95, or 1 7/95

Answer:

50m

Answer:

J. 114

Step-by-step explanation:

x + y = 25

x - y = 13

2x = 38

x = 19

x = 25 - 19

x = 6

xy = (6)(19)

xy = 114
