Answer:

When a decimal number is multiplied by a power of ten, the product is found by moving the decimal point to the right that many places as the power of ten. For example, in 3.45 × 10 2, the product is obtained by moving the decimal point two places to the right, i.e., 3.452 × 10 2 = 345.2.

Answer: choice A

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

Work Shown:

P(TV) = (number who watch tv)/(number total)
P(TV) = 30/100
P(TV) = 0.30

P(Girl) = (number of girls)/(number total)
P(Girl) = 55/100
P(Girl) = 0.55

P(TV)*P(Girl) = 0.30*0.55 = 0.165 which rounds to 0.17
We'll use this value later. So let's call this M = 0.17

Look in the "girl" row and "tv" column. The value 17 is here.
This is out of 100 people total, so
P(TV and Girl) = 17/100 = 0.17
Call this value N = 0.17

Because M = N = 0.17 approximately, this means that the two variables "TV" and "Girl" are approximately independent

So the equation P(TV and Girl) = P(TV)*P(Girl) is approximately true in this example.

This points to choice A being the answer.

2(-2×-8)+4×=2(1+3×) someone pls help​
Murljashka [212]

Answer:

x=-3

Step-by-step explanation:

2(-2x-8) + 4x = 2(1+3x)

Distribute:

-4x-16+4x=2+6x

Simplify Like-Terms:

-16=2+6x

Subtract 2 from both sides:

-18=6x

Divide both sides by 6:

x=-3

Zepler [3.9K]

Answer:

The answer is C

Step-by-step explanation:

y = 4x + 12

y = 4(3) + 12

y = 12 + 12

y=24

y = 4x + 12

y = 4(5) + 12

y=20+12

y=32

y = 4x + 12

y = 4(8) + 12

y=32+12

y=44
