John and Lauren are looking for a good neighborhood to raise their children. They want neighbors who
have kids and who are fellow rollerbladers as well. The couple surveys a random sample of residents in a
nice-looking neighborhood. Their results are shown below.
Matthew, Patrick, and Susan live in the neighborhood. Matthew rollerblades every Sunday. Patrick is a
computer programmer, but that's all we know about him. Susan is a stay-at-home mom.
Calculate the following probabilities based on the frequency table below.
Round to the nearest hundredth of a percent.

Mr. Allen needs to store his boat for winter. He needs to fill the gas tank and put fuel preserver in the tank. The fuel tank holds 70 gallons and fuel preserver mixes at a ratio of 1 oz. preserver to 2.5 gallons of gas. How much preserver will Mr. Allen need to use?
28 oz.
32 oz.
24 oz.
36 oz.
Answers
Answer:
Mr. Allen will need 28 oz. of preserver
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if p and g are proportional, then:
p = kg
Where k is the constant of proportionality.
Where p is the quantity of preserver Mr. Allen needs to store his boat for winter, and g is the gallons of gas of the tank.
We are already given the ratio of fuel preserver and gallons of gas as 1 oz:2.5 gallons.
The value of k is, then k=1/2.5. The proportion is written as:
p = g/2.5
Since the boat holds g=70 gallons of gas:
p = 70/2.5 = 28
Mr. Allen will need 28 oz. of preserver

Three friends all live on the same street that runs west to east. Ben lives 8 blocks from ann. Carol lives 2 blocks from ben. If the street is represented by a number line and ann's house is located at 0, what are the possible locations for carol's house?
Answers
Answer:
i. 10 units (Carol's house is 10 units on the right from Ann's house)
ii. -10 units (Carol's house is 10 units on the left to Ann's house)
Step-by-step explanation:
A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).
In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.
Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.
Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.
So that,
The possible locations of Carol's house depends on its position with respect to Ann's house.
i. Carol's house = 8 + 2
= 10 units
This implies that Carol's house is 10 units on the right from Ann's house.
ii. Carol's house = - 8 - 2
= -10 units
This implies that Carol's house is 10 units on the left to Ann's house.
