Linear functions from tables
I'll draw the calculations directly on the tables as required. The table that has the same slope represents a linear function.
Table A has different values for the slope, this table is not a linear function.
Table C is not a linear function since the slope is not constant
Table B does not have a constant slope, so it's not a linear function
Table D has a constant slope of 1/3, thus this table represents a linear function

As part of your job you spend time each day contacting former customers. During one week, you contacted 15 people on Monday, 12 on Tuesday, 14 on Wednesday, 11 on Thursday, and 13 on Friday. What is the average number of customers contacted each day? Which averaging method did you use?
Answers
The average number of customers contacted each day is 13. We used the basic average method which is explained below.
The formula for calculating the average is:
Sum of all the observations ÷ Total number of observations
So, according to the formula
Sum of all the observations = People contacted on (Monday+ tuesday+wednesday+thursday+friday)
= 15+12+14+11+13
= 65
Number of observations = 5
So putting values in the formula, we get
65÷5
= 13
Hence, the average number of customers contacted is 13.

Find the distance between the points (−1,0) and (7,6).
Answers
The distance between the point (-1,0) and (7,6) is 10.
Distance between the points:
Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the distance between the two points is usually given by
d=√((x2 – x1)² + (y2 – y1)²).
Given,
(−1,0) and (7,6).
Here we need to find the distance between these points.
Apply the values on the formula , in order to solve it,
d = √(7 - (-1))² + (6 - 0)²
When we simplify it, then we get,
d = √(7 + 1)² + (6)²
d = √(8)² + 36
d = √64 + 36
d = √100
d = 10
Therefore, the distance is 10.

A large cooler contains 16 lemonade 5 sprite 10 cans of coke and 9 cans of root beers you randomly pick two cans one at a time (without replacement) what is the probability you don’t get two cans of
Answers
The most appropriate choice for probability will be given by-
Probability of not getting two cans of coke is [tex]\frac{49}{52}[/tex]
What is probability?
Probability of an event is the chance of occurance of that event.
Probability is calculated by Number of favourable outcomes divided by total number of outcomes
Here,
Number of lemonades in a cooler = 16
Number of sprite in a cooler = 5
Number of cans coke in a cooler = 10
Number of cans of root beers in a cooler = 9
Total number of refreshments = 16 + 5 + 10 + 9
= 40
Probability of getting a can of coke in the first draw = [tex]\frac{10}{40}[/tex]
= [tex]\frac{1}{4}[/tex]
Probability of getting a can of coke in the second draw = [tex]\frac{9}{39}[/tex]
= [tex]\frac{3}{13}[/tex]
Probability of getting two cans of coke in the two draws = [tex]\frac{1}{4} \times \frac{3}{13}[/tex]

Probabilty of not getting two cans of coke in the two draws = [tex]1-\frac{3}{52}[/tex]

5) The probability that when 75 people are surveyed, at least five of them have the same birth date. (Ignore leap years).
Answers
Using the binomial distribution, the probabilities are given as follows:
1) Three girls in a family of five children: 0.3125 = 31.25%.
2) At least two boys in a family of seven children: 0.9375 = 93.75%.
3) Total of 15 when four dice are thrown: 0.1080 = 10.80%.
4) At least two left-handed people in a group of 7: 0.1497 = 14.97%.
5) At least five of them have the same birth date: 0%.
What is the binomial distribution formula?The formula for the probability of x successes is:
[tex]P(X = x) = C(n,x).p^{x}.(1-p)^{n-x}[/tex]
[tex]C(n,x) = \frac{n!}{x!(n-x)!}[/tex]
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.Item 1A children is equally as likely to be a boy or a girl, hence the parameters are given as follows:
n = 5, p = 0.5.
The probability is P(X = 3), hence:
P(X = 3) = C(5, 3) x (0.5)³ x (0.5)² = 0.3125 = 31.25%.
Item 2The parameters are:
n = 7, p = 0.5.
The probability of at least two boys is:
P(X >= 2) = 1 - P(X < 2).
In which:
P(X < 2) = P(X = 0) + P(X = 1).
Then:
P(X = 0) = (0.5)^7 = 0.0078.P(X = 1) = C(7,1) x (0.5)^7 = 0.0547.P(X < 2) = P(X = 0) + P(X = 1) = 0.0078 + 0.0547 = 0.0625.P(X >= 2) = 1 - P(X < 2) = 1 - 0.0625 = 0.9375 = 93.75%.Item 3This one is simple probability, number of desired outcomes divided by the number of total outcomes.
When 4 dice are thrown, we have that:
There are 140 outcomes with a sum of 15.There are 6^4 total outcomes.Hence the probability is:
p = 140/(6^4) = 0.1080 = 10.80%.
Item 4The parameters are:
n = 7, p = 0.1.
Hence, similarly to item 2:
P(X = 0) = (0.9)^7 = 0.4783.P(X = 1) = C(7,1) x (0.1) x (0.9)^6 = 0.3720.P(X < 2) = P(X = 0) + P(X = 1) = 0.4783 + 0.3720 = 0.8503.P(X >= 2) = 1 - P(X < 2) = 1 - 0.8503 = 0.1497 = 14.97%.Item 5The parameters are:
n = 75, p = 1/365 = 0.0027.
Then the probability is:
P(X >=5) = 1 - P(X < 5).
In which:
P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4).
Using a calculator, it is found that P(X < 5) = 1, hence the probability is of 0%, as P(X >=5) = 1 - 1 = 0.

x+12% of x= 3.36 help
Answers
Answer:
x = 3
Step-by-step explanation:
x + .12x = 3.36 Combine like terms
1.12x = 3.36 Divide both sides of the equation by 1.12
x = 3
=======================================
Work Shown:
12% = 12/100 = 0.12
x + 12% of x = x + 0.12x = 1.12x = 3.36
1.12x = 3.36
x = 3.36/1.12
x = 3
---------------
Check:
12% of 3 = 0.12*3 = 0.36
x + 12% of x = 3 + 12% of 3 = 3 + 0.36 = 3.36
Or you could say 1.12x = 1.12*3 = 3.36
The answer is confirmed.

A bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months. Find the interest rate.
Answers
If the bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months, then the interest rate is 30%
The initial amount = $1100
The final amount = $1265
So simple interest = 1265-1100
= $165
Time period = 6 months = 6/12 years
We know
Simple interest I = P×r×t
Where P is the initial amount
r is the interest rate
t is the time period
Substitute the values in the equation
165 = 1100×r×(6/12)
165 = 550×r
r = 165/550
r = 0.3
r = 30%
Hence, If the bank deposit paying simple interest grew from an initial amount of $1100 to $1265 in 6 months, then the interest rate is 30%

Therefore, using equation,
let
x = amount paid each month
The monthly payment can be found as follows:

1615 - 400 = 18x

divide both sides by 18
x = 1215 / 18

What is Percent?Percentages are basically fractions with a denominator of 100. We use the percent symbol (%) beside a number to indicate that it is a percentage. A percentage is a relative value that represents the hundredth part of any quantity. One percent (symbolized 1%) is one hundredth part; thus, 100 percent represents the entire amount.
What is method to calculate the percent?To manually calculate percentages, follow these steps:
1. Determine the number's initial format to be converted to a percentage.
The decimal or fraction format of the number to be converted to a percentage can be used. The next mathematical process to be performed on the number will be determined by the initial format.
2. Perform a mathematical calculation on the number to be converted to a percentage.
If the number to be converted to a percentage is a decimal number, such as 0.57, you may not need to proceed to the next step.
3. Multiply the result by 100.
