Five carpenters worked 15 & 3/4, 15 & 1/4, 17 & 1/2, 12 & 1/2 and 17 & 1/2 hours respectively. What was the

azamat

<u>The total </u><u>labor cost</u><u> of the carpenters is $2296.91</u>

The carpenters worked $15\frac{3}{4} , 15\frac{1}{4}, 17\frac{1}{2}, 12\frac{1}{2}, 17\frac{1}{2}$

<h3>Conversion of Fraction</h3>

Let's convert the mixed fraction to improper fraction

So, we would have

63/4,
61/4,
35/2,
25/2
35/2.

<h3>Working Cost</h3>

Let's sum it up and multiply by the working cost per hour

$63/4 + 61/4 + 35/2 + 25/2 + 35/2 =78.5$

The total labor cost is = total hours worked * hourly rate.

This becomes $78.5*29.26=2296.91$

<u>The total labor cost is $2296.91</u>

Find the residual values, and use the graphing calculator tool to make a residual plot. A 4-column table with 5 rows. The first

Svetlanka [38]

The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern

X Given Predicted Residual value

1 3.5 4.06 -0.56

2 2.3 2.09 0.21

3 1.1 0.12 0.98

4 2.2 -1.85 4.05

5 -4.1 -3.82 -0.28

The residual value is calculated as follows using this formula: ( Given - predicted )

1) ( 3.5 - 4.06 ) = -0.56

2) ( 2.3 - 2.09 ) = 0.21

3) ( 1.1 - 0.12 ) = 0.98

4) (2.2 - (-1.85) = 4.05

5) ( -4.1 - (-3.82) = -0.28

Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .

attached below is the residual plot of the data set

hence we can conclude from the residual plot attached below that the line of best fit is appropriate for the data because the points have no clear pattern ( i.e. scattered )

So,

The skateboard cost $67.
The protective helmet cost $25.

To find the percent that the price of the skateboard was out of the total amount, add 67 and 25 and divide 67 by the result.

Step 1:
67 + 25 = 92

Step 2:
67/92 = 0.728 or 72.8%.

The correct option is B.

How do you calculate it? You start by expressing the density in the units you have. Then you multiply by appropriate conversion factors to get to the units you want. Treat units as though they were any other variable. A value cancels that appears in both the numerator and denominator of a fraction.

$\dfrac{56.15\,kg}{0.222\,hh}\cdot \dfrac{1000\,g}{1\,kg}\cdot \dfrac{1\,pw}{1.55\,g}\cdot \dfrac{1\,hh}{238.5\,L}\cdot \dfrac{9.091\,L}{1\,pk}\\\\=\dfrac{56.15\cdot 1000\cdot 9.091\,pw}{0.222\cdot 1.55\cdot 238.5\,pk}\\\\ \approx6220\,\frac{pw}{pk}$

Help plz!! Has to do with concepts

Answer:

f(2) =4, f(4) =4, x=8, x=3

Step-by-step explanation:

f(2) is asking for what the y value is when x is 2. f(4) is also asking what the y value is when x=4. When y=-2 the x is 8 and when the y=6 x=4. I hope this is helpful.
