Find the equation of a line that has slope, m, of 4 and passes through the point (10, 15).
Step-by-step explanation:
m=4 , (10, 15)
straight line equation:
y= mx +c
substituting the values:
15=4(10) + c
15 = 40 + c
15 - 40 = c
c = -25
therefore,
y = 4x - 25 (ans)

You are offered a 30--day trial period at your dream job. However, the owner of the company is a little unusual so the pay options are non-traditional. They offer you two different pay options for the 30 days:
Option 1: You make $60,000 per day.
Option 2: You make 1 penny the first day, 2 pennies the second day, 4 pennies the third day, 8 pennies the fourth day, etc.
Which is $5,368,709.12 after 30 days of working.
Answer:
The question is not complete but from the flow of thought, the question seems to be about what your choice will be between option 1 and option 2.
The correct answer is
option 2
Step-by-step explanation:
The question is asking you to choose an option that pays more after 30 days. In other to determine the more beneficial option, we will compare both options and select the one that pays more. This is done as follows:
option 1: $60,000 per day, after 30 days =
60,000 × 30 = $1,800,000
option 2 = $5,368,709.12 after 30 days
From the total amounts after 30 days of the two options listed above, option 2 is higher than option 1 by $3,568,709. Therefore, option 2 is a better choice.

There will be 340 people on a school trip to Washington, D.C. Each school bus holds
45 people, and all the buses will be filled except for the last bus. How many school
buses will be needed and how many people will be on the last bus?
A. 8 buses with 25 people on the last bus
B. 7 buses with 25 people on the last bus
C. 8 buses with 35 people on the last bus
D. 8 buses with 45 people on the last bus
Step-by-step explanation:
340 people ÷ 45 per bus = number of busses.
340÷45=7.555555555
7 full busses
45 people × 7 busses = 315 people with seats
340 people total - 315 people with seats = 25 people left
answer A. 8 busses with 25 on last bus.
There will be 8 busses needed with 25 on last bus. so option A is correct.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given; There will be 340 people on a school trip to Washington, D.C.
Each school bus holds 45 people, and all the buses will be filled except for the last bus.
So, 340 people ÷ 45 per bus = number of busses.
340÷45 = 7.555555555
The numebr of buses = 7 full busses
Then, 45 people × 7 busses = 315 people with seats
340 people total - 315 people with seats = 25 people left
Hence, There will be 8 busses needed with 25 on last bus. so option A is correct.

Suppose that a nonzero constant b is added to every value of a generic sample dataset 1 2 3 { , , , , }n x x x x , to produce a new dataset 1 2 3 { , , , , } n x b x b x b x b . Provide a formal mathematical (i.e., algebraic) proof for what happens to the mean, variance, and standard deviation. (Hint: Think of the dotplot for informal motivation.)
Answer:
Step-by-step explanation:
Suppose there is the addition of a constant "b" to each generic dataset, then, new mean = old mean + b. This will affect the variance and the standard deviation of the resulting dataset to remain the same:
From the information given:
[tex]\mathbf{x_1,x_2,x_3...x_n \ have \ mean \ \overline x }[/tex]
Proof:
If c is added to each data set:
Then,
[tex]\mathbf{x_1+c,x_2+c,x_3+c...x_n+c \ and \ the \ new \ mean \ \overline x = \overline x + c}[/tex]
also;
[tex]\mathbf{New \ Sd^2 = \dfrac{(x_1+c -(\overline x+c))^2+ (x_2+c -(\overline x+c))^2 +...+ (x_3+c -(\overline x+c))^2}{n}}[/tex]
[tex]\mathbf{New \ Sd^2 = \dfrac{(x_1+c -\overline x+c)^2+ (x_2+c -\overline x+c)^2 +...+ (x_3+c -\overline x+c)^2}{n}}[/tex]
[tex]\mathbf{New \ Sd^2 = (x_1- \overline x)^2+ (x_2- \overline x)^2+ ... +(x_n- \overline x)^2}[/tex]
