Mr. Wong predicted that he would sell 45 automobiles. He actually sold 48 automobiles. What are the values of a and b in the tab
iVinArrow [24]

Answer:

<h2>a = 3.45</h2><h2>b = 6.67%</h2>

Step-by-step explanation:

Initial prediction of sales = 45 automobile

Actual amount sold = 48 automobiles

Absolute error ratio a = actual amount sold - initial prediction/initial prediction

Absolute error ratio a = 48-45/45

Absolute error ratio a = 3/45

%error = actual amount sold - initial prediction/initial prediction * 100%

% absolute error = 48-45/45 * 100

% absolute error = 3/45 * 100

% absolute error b = 6.67%

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to th
Allushta [10]

Answer:

y>\frac{2}{3}x+3

Step-by-step explanation:

step 1

Determine the slope of the dashed line

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-3,1) and (0,3)

substitute

m=\frac{3-1}{0+3}

m=\frac{2}{3}

step 2

Find the equation of the dashed line in slope intercept form

y=mx+b

we have

m=\frac{2}{3}

b=3 ---> given problem

substitute

y=\frac{2}{3}x+3

step 3

Find the equation of the inequality

we know that

Is a dashed line and everything to the left of the line is shaded

so

y>\frac{2}{3}x+3

see the attached figure to better understand the problem

How to convert pounds to ounces
raketka [301]
To convert pounds to ounces we can use a conversion factor. For instance, a conversion factor can be used to turn 2 pounds to ounces. Lets do that real fast.

First we need to find out how many pounds are in an ounce. 

1 pound = 16 ounces  
OR
1:16
OR
1 lb/ 16 ounce
OR
16 ounces / 1 lb

Now to convert we just use the conversion factor by multiplying the pounds by the conversion factor 16 ounces / 1 lb
2 \; lb \times \frac{16 \; ounces}{1 \; lb} = 32 \; ounces
