Answer:

AB would be 18 or the first choice.

Since BD is the median that means from A to D and from D to C are equal. We set this up as an equation and solve it.

x + 8 = 2x - 17

  + 17       +17

x + 25 = 2x

-x            -x

    25 = x

This gives us our first bit of the answer. Then we plug this into our equation for the length of AB to get 18.

i. 4x² + 96x + 512

ii. 1,092 m²

Step-by-step explanation:

i. [ 36 + 2 (x - 2) ] × [ 20 + 2 (x - 2) ]

= (36 + 2x - 4) (20 + 2x - 4)

= (32 + 2x) ( 16 + 2x)

= 512 + 64x + 32x + 4x²

= 4x² + 96x + 512.

---------------------------------------------------------------------

ii. If x = 5

then 4x² + 96x  + 512

= 4 × 25 + 96 × 5+ 512

= 100 + 480 + 512   (Simple calculation)

= 1,092 m²

The mean vitamin C level for 20 dogs was 7.6 milligrams per liter, with a standard deviation of 2.1 milligrams per liter.

One dog’s vitamin C level was not in the normal range. It was 0.9 milligrams per liter, which is a very low level of vitamin C.

If the value 0.9 is eliminated from the data set, does the mean increase or decrease?

Your answer:
I will give you 5.0 and a thanks and maybe brainliest

Answers

Answer:  The mean increases.

Step-by-step explanation:

The value of 0.9 mg/L is very low compared to a means of 7.6 mg/L with a standard deviation of 2.1 mg/L.  It seems as though it is an outlier that is suffiently different from the others, and probably should be dropped from the data set.  That would do 2 things:  1) the stabdard deviation will likely decrease, indicating a more confident data set, and 2) the mean vitamin C level will increase.

By what factor would your weight be multiplied if earth's diameter were 1/ 4 as big and earth's mass remained unchanged?.

Answers

Answer:

Step-by-step explanation:

Your weight is (roughly) proportional to the inverse of the square of the distance you are from the center of the earth. If that distance is reduced to 1/4 its previous value, then your weight will be multiplied by the factor ...

Answers

Step-by-step explanation:

T  |  0   |   1    |  2   |  3   |

C  | 24  |  21  |  18  |  15  |

Rule:

To find a rule, we need to find 2 things- what T is multiplied by and what is added.

To find what it is multiplied, we need to see the increase or decrease in C for every T. In this equation, there is a decrease of 3, so we multiply T by -3.

To find what is added, we go to 0 T and find the corresponding number. When T is 0, C is 24 so we add 24.

We write a rule as:  y = mx + c, or in this case, c = mt + a

So the rule is c = -3x + 24

Her little sister's birthday is next week, so Erin is planning a bubble-themed birthday party!

1
of a gallon of bubble solution.
16
Use an equation to find the amount of bubble solution in the big bottle.
To write a fraction, use a slash (/) to separate the numerator and denominator.

Answers

Answer:

The answer and solution is in the picture

An equation is formed of two equal expressions. The equation that can represent the amount of solution in a small bottle is x=y/8.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the bubble solution in the small bottle be represented by x, while the amount of solution in the big bottle is represented by y. Since the sum of the solution of 8 small bottles is equal to a big bottle. Therefore, the equation can be written as,

The amount of solution in the big bottle) = (Amount of solution in a small bottle)×8

y = 8x

x = y/8

Hence, the equation that can represent the amount of solution in a small bottle is x=y/8.
