Answers

Answer 1

Answer:

the answer is in the picture

Have a safe and happy new years

Step-by-step explanation:

-2(x + 3) = -2x + 3 - 9
Answer 2

Answer:

x = x

Step-by-step explanation:

The first step here is to use the distributive property to make the first equation back into a polynomial.

The way we do this is by multiplying each term on the inside of the parentheses by the -2 on the outside.

-2 x x = -2x

-2 x 3 = -6

So, our new equation reads: -2x - 6

-2x - 6 = -2x + 3 - 9

Our next step is to subtract the 9 from 3.

-2x - 6 = -2x - 6

We add 6 to each side

-2x = -2x

x = x

0 = 0

A two digit number is such that, the sum of its digit is 13.When the digits are interchange, the original number is increased by 9. Find the original number.​

Answers

Answer:

Concept: Mathematical Representation

You have a two digit # __ The sum of the two digit # = 13The original # increased by 9 Hence we must find values that sum to 13. *Note they must be independently standing.8+5, 9+6, 7+6 , 6+7 , and etcThe value must also increase by 9 So logically it would be any result that when switched that value would be 76-67= 9.So the value must be 67

A random sample of 20 married women showed that the mean time spent on housework by them was 29.8 hours a week with a standard deviation of 6.7 hours. If the margin of error is 3.14, find a 95% confidence interval for the mean time spent on housework per week by all married women.

Answers

Answer:

95% confidence interval for the mean time spent on housework per week by all married women.

( 26.66 , 32.94)

Step-by-step explanation:

Step(i):-  

Given random sample size 'n' = 20

Mean of the sample (x⁻ ) = 29.8 hours

Standard deviation of the sample (S) = 6.7

Given Margin of error = 3.14

Step(ii):-

95% confidence interval for the mean is determined by

[tex](x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} +t_{0.05} \frac{S}{\sqrt{n} })[/tex]

We know  that margin of error is determined by

[tex]M.E = \frac{t_{0.05}XS.D }{\sqrt{n} } = 3.14[/tex]

Now 95% confidence interval for the mean time spent on housework per week by all married women.

[tex](29.8 - 3.14 , 29.8+3.14)[/tex]

Graph of the given piecewise function will show the three straight lines,

f(x) = 2  If 2 < x ≤ 4

        x + 3 If 4 < x < 8

        2x If x ≥ 8

1). f(x) = 2 will be a straight line parallel to x-axis for 2 < x ≤ 4

2). f(x) = x + 3 is a straight line with input output points in the interval 4 < x < 8

       x               4                  5          6         7              8      

     f(x)        Not defined      8          9         10    Not defined  

3). f(x) = 2x

      x            8         9          10         11

     f(x)         16        18         20       22

By using these points on a graphing calculator we can graph the piecewise function as attached.      

moving company rents moving trucks for $20 plus $0.19 per mile. Suppose a customer’s total bill for renting a truck comes to $34.06. How many miles did the customer drive? Write an equation and explain how you used it to find your answer.​

Answers

Answer:

34.06=20+0.19m

Step-by-step explanation:

The 20 dollars is a one-time thing so we don't need a variable for that. The 0.19 per mile does because the cost will depend on how many miles you drove (I used the variable 'm' but you could use a different letter). Altogether the bill costs 34.06 so that will go on the opposite side of our equal side.

34.06=20+0.19m

First we need to isolate 0.19m to find the number of miles the customer drove, and we can do that by subtracting 20 on each side.

34.06-20=20-20+0.19m

14.06=0.19m

Now we divide 0.19 because 0.19 is multiplied to m and division is the opposite operation

m=74

This means that the customer drove 74 miles.
