Answer:

x^4

Step-by-step explanation:

The expression can be simplified to (x^2)^2. Using an exponent rule, you multiply the two exponents together to get 4. The answer is x^4

I need help with 5-9
Goryan [66]

Answer:

5) x = 1, y = -3

6) x = -20, y = 2

7) infinite solutions

8) no solutions

Step-by-step explanation:

5)

y = 5x - 8

y = -6x + 3

5x - 8 = -6x + 3

11x = 11

x = 1

y = 5 - 8

y = -3

6)

2x + 10y = -20

-x + 4y = 28

2x = -20 - 10y

x = - 10 - 5y

-x = 28 - 4y

x = -28 + 4y

-10 - 5y  = -28 + 4y

-10 + 28 = 4y + 5y

18 = 9y

2 = y

2x + 20 = -20

2x = -40

x = -20

7)

this has infinite solutions because one equation is a simplified version of the other

8)

this has no solutions because 5 does not equal -5

9)

In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft. For a group of 1013 adults, the mea
Kazeer [188]

Answer:

Mean = 344

Step-by-step explanation:

Given

Population =  1013

Let p represents the proportion of those who worry about identity theft;

p = 66\%

Required

Mean of those who do not worry about identity theft

First, the proportion of those who do not worry, has to be calculated;

Represent this with q

In probability;

p + q = 1

Make q the subject of formula

q = 1 - p

Substitute p = 66\%

q = 1 - 66\%

Convert percentage to fraction

q = 1 - 0.66

q = 0.34

Now, the mean can be calculated using:

Mean = nq

Where n represents the population

Mean = 1013 * 0.34

Mean = 344.42

Mean = 344 (Approximated)
