The coordinate of point B is such that M (1,-8) is the midpoint of A(-6,-12) and B will be (5,-2).
What are coordinates?A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
The coordinate of midpoint between two points (x₁, y₁) and (x₂, y₂) is given by,
( (x₁ + x₂)/2 ,(y₁+ y₂)/2)
Given that, M is the midpoint of A and B.
Let's say the coordinate of point B is B(x,y).
Then,
1 = (-3 + x)/2
x = 2 + 3 = 5
And,
(-6 + y)/2 = -4
y = -8 + 6 = -2
Hence "The coordinate of point B is such that M (1,-8) is the midpoint of A(-6,-12) and B will be (5,-2)".

A bank found that 2.5% of its loans to new small businesses become delinquent. If 400 small businesses are selected randomly from the bank’s files, what is the probability that at least 12 of them are delinquent? Use a TI-83, TI-83 plus, or TI-84 calculator to find the probability.
.3155
The probability that at least 12 are delinquent is given as 0.3155
How to solve for the probabilityProbability can be defined as the likelihood of getting an outcome out of other outcomes.
We have the mean u = np
where n = 400
p = proportion = 2.5% = 0.025
= 400 x 0.025
= 10
we have to find the population standard deviation
= [tex]\sqrt{np(1-p)}[/tex]
= √400 x 0.025 (1 - 0.025)
= 3.1225
P (X ≥ 12)
= P(X ≥ 11.5)
= 11.5 - 10 / 3.1225
= 1 - P(z < 0.4804)
= 1 - 0.6845

b If w = 15.5, how much gasoline was left in the tank at the end of the journey?
gal
a) An algebraic expression for the gasoline left in the fuel tank is L = 0.4w.
b) If w = 15.5, the amount of gasoline left in the tank at the end of the journey was 6.2 gallons.
What is an algebraic expression?An algebraic expression is a mathematical statement that combines constants and variables together with mathematical operands.
The mathematical operands include addition, subtraction, division, multiplication, etc.
Let L = the amount of gasoline left
Let the full capacity of the fuel tank = w gallons
Gasoline consumed on the journey = 60% = 0.6
Equation:L = w - 0.6w
L = 0.4w
Solution:If w = 15.5
L = 0.4(15.5)

The third grade teachers had a pizza party. They ordered 11 large pizzas and each pizza had 8 slices. There were 4 classrooms in the grade. Estimate how many slices of pizza each classroom can have if the pizzas are shared equally.
Choose 1 answer: 20 slices 50 slices 300 slices 320 slices
Answer:
20 slices
Step-by-step explanation:
If there were 11 large pizzas with 8 slices per pizza, that would mean that there are a total of 88 slices of pizza.
If there are four classrooms, that means that if each classroom had 20 slices, there would be enough for everyone with 8 pieces leftover.
20 x 4 = 80
You want to have $300,000 when you retire in 30 years. If you can earn 4% interest compounded continuously, how much would you need to deposit now into the account to reach your retirement goal?
An amount of $ 92,495.60 must be the initial deposit to become into $ 300,000 by compound interest.
How much money must be deposited to obtain a given quantity for retirement?
In this problem we must determine the initial deposit that must become into $ 300,000 by compound interest after a period of 30 years. Compound interest model is a model where money gains interest continuously, whose formula is:
C' = C · (1 + r / 100)ⁿ
Where:
C - Initial deposit, in monetary units.C' - Final deposit, in monetary units. r - Interest rate, in percentage.n - Number of periods, in years.If we know that C' = 300,000, r = 4 and n = 30, then the initial deposit is:
C = C' / (1 + r / 100)ⁿ
C = 300,000 / (1 + 4 / 100)³⁰
C = 92,495.60
The initial deposit must be $ 92,495.60.

and a base diameter of 20 centimeters? Round to the nearest tenths place?
The volume of the cylinder in cubie centimeter is 628 [tex]cm^{3}[/tex]
How to find the volume of cylinder?
1. Find the radius of the circular base: Since both circles are the same size, either one will work. Move on if you are aware of the radius. If you don't know the radius, you can divide the diameter of the circle by 2.
2. Find the height of the cylinder : Continue if you already know the height. Otherwise, measure it with a ruler. The height is determined by the separation of the two bases' edges.
diameter (d) = 20
radius = [tex]\frac{20}{2}[/tex]
r = 10

What should be added to 5/6 to get 41/24
Answer: 26/24
Step-by-step explanation:
First we have to convert 5/6 with a denominator of 24 so 6 times what makes 24, that is 4 & whatever you do with the denominator, you have to do it with the numerator. So 5 times 4 is 20, the new fraction is 20/24. Now, we need to find what we need to add with 20/24 to get 41/24, so we subtract 20/24 from 41/24 & that is 21/24. We can check if it's correct by adding both 21/24 and 20/24 & that makes 41/24.

140 + (2x) = 180
2x = 180 - 140
2x = 40
