Answer:

\frac{6}{8} (Proper Fraction)

Step-by-step explanation:

Pick any two points from the graph and trace points to the y-axis and x-axis.

slope of a graph m= y₂-y₁/x₂-x₁

From graph, points picked on the y-axis are 90 and 30, now trace this points to the x-axis, 90 on the y-axis is 90 on the x-axis and 30 on the y-axis is 10 on the x-axis.

Therefore,

y₂= 90

y₁= 30

x₂= 90

x₁= 10

slope of a graph m= y₂-y₁/x₂-x₁

Slope m= \frac{90-30}{90-10}

m=\frac{60}{80}

m=\frac{6}{8}

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.
Alex Ar [27]

Answer:

B = 4x + 8

A box = $11

Step-by-step explanation:

Given

Total = 7x + 13

Represent the first order with A and the second with B.

So, we have:

A = 3x + 5

Solving (a): Find B.

To find B, we make use of:

A + B = Total

Make B the subject

B = Total - A

Substitute values for Total and A

B = 7x + 13 - (3x + 5)

Open bracket

B = 7x + 13 - 3x - 5

Collect Like Terms

B = 7x - 3x + 13 - 5

B = 4x + 8

Solving (b): Cost of a box of light bulb

This means that:

Total = 90

Substitute 7x + 13 for Total

7x + 13 = 90

Collect Like Terms

7x = 90 - 13

7x = 77

Make x the subject

x = \frac{77}{7}

x = 11

if we do a test of independence  

null hypothesis : H 0: Being a cell phone user while driving and receiving a speeding violation are independent events. If the null hypothesis were true, we would expect about 28 people to use cell phones while driving and to receive a speeding violation.

Therefore in the given question Each respondent answer that it might be in "Right Direction " or "Wrong Direction".
