Answer:

88

Step-by-step explanation:

all the angles added up must equal 360 degrees add x and v and subtract with 360 and divide that by 2

Answer:

Step-by-step explanation:

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.      

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]

( 26.66 , 32.94)

Answer:

1) 36, 2) 14, 3) 19, 4) 18, 5) 3, 6) 117

Step-by-step explanation:

1)  6(7) - 3(2)   2)  (7)(4)/2   3)  (7) + |2(7) - (2)|   4)  6(5) - 4(3)   5)  [(4) + (5)]/3  

    42 - 6             28/2            7 + |14 - 2|               30 - 12            9/3

    36                   14                7 + 12                      18                    3

                                               19

6)  (4) + [(5)^3 + (3)] - 15

     4 + (125 + 3) - 15

     4 + 128 - 15

     132 - 15

     117

Answer:

-1

Step-by-step explanation:

Answer:

slope is 1/2 and the y intercept is -1

Answer:

25/ 100 × 16.4 (25 and 100 is cancelled by 5)

5/20 × 16.4 ( 5 and 20 are cancelled by 5)

4 ÷ 1 6.4

The answer will be 4.1...

Answer:

90 Cookies

Step-by-step explanation:

4.50 ÷ .05 = 90

Answer:90 cookies

Step-by-step explanation: Here is what I did, I calculated 4.50 divided by 0.05 because it is 5cents. I divided it that why because we are trying to know how many cookies we sold out of that number. please tell me if I'm wrong and I'm sorry it I am wrong you can correct me if you want. hope this helps :)

Answer: 1.278, 1.281, 1.284

Step-by-step explanation:

Answer:

I would say that A  is your answer.

I think this because you would not need to have any specific number of trees in your yard, but you would need a specific number of things for all of your other options.

Step-by-step explanation:

You probably wouldn't approximate on how many chairs you put in a kitchen. What if you have a 5-member family and you aproxomate the chair number to 4. that would be useless so B is wrong.

C is wrong because you are only getting 1 barbaque. no approximation is nessisary for one item.

D is certainly wrong because you wouldn't want to leave out a uniform, that would mean one member of the basketball team may not get one.

Answer:

(8,3)

Step-by-step explanation:

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.
