Answer:
32
Step-by-step explanation:
slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (32 - 14) / 0 - (-6)
= 18 / 6
= 3
y-intercept, use any point to determine b, let's use (2, 38) :
y = mx + b
38 = 3(2) + b
38 = 6 + b
b = 32
There are 52 contacts in your phone. The only family members' numbers you have are your dad's, mom's, and brother's. What are the odds of selecting a number in your phone that is not your family? Write your answer as 1:2 which is reduced as much as possible.
Answer:
49:52
Step-by-step explanation:
Given that:
Total number of contacts on phone = 52
Family members in phone book : dad, mom, brother
Total number of family members = 3
Hence, non family members = 52 - 3 = 49
Number of family members to total phone contact
Selecting a contact that is not a family member :
49 : 52
Answer:
the answer is 49:3 :)

Question 2/3 A swimming pool holds 18,000 gallons of water. A pool
company can drain the water in a pool at a rate of 60 gallons per minute. 300
gallons have already been drained. How long will it take to drain the remaining
water in the pool?
Answer:
296 minutes
Step-by-step explanation:
18,000 - 300 = 17,700.
17,700 ÷ 60 = 296.
It will take 296 minutes to drain the whole pool.

To reduce laboratory costs, water samples from public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the combined sample tests positive. Based on past results, there is a probability of finding bacteria in a public swimming area. Find the probability that a combined sample from public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples is rarely necessary?
Complete Question
The complete question is shown on the first uploaded image
Answer:
The probability is [tex]P(X \ge 1 ) = 0.003996[/tex]
Given that the probability is less than 0.05 , it means that it is low enough so that further testing of the individual samples is rarely necessary
Step-by-step explanation:
From the question we are told that
The probability of finding bacteria in a public swimming area is p = 0.002
Generally the probability of not finding bacteria in a public swimming area is mathematically represented as
[tex]q = 1- p[/tex]
=> [tex]q = 1- 0.002[/tex]
=> [tex]q =0.998[/tex]
Generally the the probability that a combined sample from public swimming areas will reveal the presence of bacteria is equivalent to the probability that at least one of the sample will reveal the presence of bacteria and this is mathematically represented as
[tex]P(X \ge 1 ) = 1 - P(X')[/tex]
Here [tex]P(X')[/tex] means that none of the 2 sample have bacteria which is mathematically represented as
[tex]P(X') = q^2[/tex]
Here 2 signifies that we are considering two samples
So
[tex]P(X') = 0.998^2[/tex]
[tex]P(X') = 0.996004[/tex]
So
[tex]P(X \ge 1 ) = 1 - 0.996004[/tex]
=> [tex]P(X \ge 1 ) = 0.003996[/tex]

The door to my classroom is 84 inches tall. How many blocks would I need to stack to the height of the door, If each block is 2 inches tall?
Answer:
42 blocks

QUESTION 8
Solve the problem that involves probabilities with events that are not mutually exclusive.
Consider a political discussion group consisting of 8 Democrats, 3 Republicans, and 7 Independents. Suppose that two
group members are randomly selected, in succession, to attend a political convention. Find the probability of selecting
an Independent and then a Democrat.
14/81, 25/153, 7/306/ or 4/153?
Answer:
Option (2).
Step-by-step explanation:
Number of Democrats in a political discussion = 8
Number of Republicans = 3
Number of independents = 7
Total members in the discussion = (8 + 3 + 7)
= 18
Probability of selecting an independent = [tex]\frac{7}{18}[/tex]
Remaining members after selecting one independent = 17
Probability of selecting a Democrat = [tex]\frac{8}{17}[/tex]
Probability of selecting a Republican then a Democrat = [tex]\frac{7}{18}\times \frac{8}{17}[/tex]
= [tex]\frac{28}{153}[/tex]
Therefore, Option (2) will be the answer.
