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:

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.

Step-by-step explanation:

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:

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.

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:

96%

Step-by-step explanation:

If you substitue values for the sides of the square, you can easily solve this problem.

If the side of each square was 10, then the area of the square would be 100. A 40% increase in side length would mean 10×.4 = 4 --> 10+4= 14.

14 would be your new side length meaning that the area would be 196.

From this, you can see that there is an increase by 96 from the original to the 40% increase. Since the value was initially 10, we can turn the 96 increase into 96 percent.

Answer:

40% iincrease

Step-by-step explanation:

A=l^2  (area of a square)      let the unknown dimensions be x                                                                                                                   Area of the original square without change=(x^2)                                                          Area of the square undergoing change =(1.4x^2)                                                            thus,% change=new-old/old*100%                                                                                   1.4-1.0=0.4*100=40%
