Part of your bathroom remodel involves you needing to repaint. the walls measure to be 150 square feet. if a gallon of paint covers 400 square feet, how many gallons do you need to buy if you need 2 coats?
I need to buy 0.75 gallons of paint 2 coats on the wall.
We are given the area of wall, which is 150 square feet. So, if I need to put double or two coats on the wall, the area of wall to be considered will be : 150 × 2
Area of wall to be considered = 300 square feet
As per the information on paint -
400 square feet is covered by amount of paint = 1 gallon
300 square feet will be covered by amount of paint = (1 ÷ 400) × 300
Amount of paint = 300 ÷ 400
Amount of paint = 0.75 gallons
Therefore, I need to buy 0.75 gallons of paint 2 coats on the wall.

Mathematically, an odds ratio equates to a risk ratio, therefore, odds ratios can be interpreted in an exactly same way as risk ratio.
true/ false
False, Mathematically, an odds ratio equates to a risk ratio, therefore, odds ratios can be interpreted in an exactly same way as risk ratio.
What distinguishes risk from probability?
The fundamental distinction is that the relative risk is a ratio of two probabilities, but the odds ratio is a ratio of two odds (yes, it's that clear). (The risk ratio is another name for the relative risk.)
Used to approximate the relative risk in case-control studies, when the occurrence of diseases are KNOWN
odds of an event = the number of ways an event can occur to the numbers of ways an event cannot occur
odds ratio = P / (1-P)

An executive invests 28,000 some at 7% and the rest at 4% annual interest if he receives an annual return of $1,570 how much is invested at each rate
we get that the amount invested at 7 % interest rate is $ 15,000 and at 4 % interest rate is $ 13,000.
We are given that:
the total amount invested is = $ 28,000
Let the amount invested at 7 % interest rate be x
Amount invested at 4 % interest rate = 28,000 - x
Interest received at the end of year = $ 1570
ATQ:
7 % x + 4 % ( 28,000 - x) = 1570
7 x + 4 (28,000 - x) = 157000
7 x + 112,000 - 4 x = 157,000
3 x = 157,000 - 112,000
3 x = 45,000
x = 45,000 / 3
x = 15,000
Amount invested at 7 % interest rate = x = $ 15,000
Amount invested at 4 % interest rate = 28,000 - x = $ 13,000
Therefore, we get that the amount invested at 7 % interest rate is $ 15,000 and at 4 % interest rate is $ 13,000.

the world record for the most number of speed skips is 60 seconds is 332 skips if the record holder skipped at a constant ratio of seconds to skips how many makes in 15 seconds
The record holder skips 83 times in 15 seconds
We refer to a ratio as constant if the number we multiply by remains constant throughout the series.
By comparing two amounts of the same units, the ratio can be used to calculate how much of one item is included in the other. There are two different categories for ratios. The first is a part-to-part ratio, whereas the second is a part-to-whole ratio.
The World record for the most number of skips is 332 in 69 seconds.
Let's assume the record holder skipped at a constant ratio.
The proportion, if s is the number of skips:
skips / seconds = s / 15 = 332/60
s / 15 = 332 / 60
s = 332( 15/60 )
s = 332/4
s = 83

Which describes the graph of y= -(x - 3)² + 2?
which means the graph is on quadrate 2 or 3.
Straight Line :
A straight line is an infinite-length line that does not have any curves on it. A straight line can be formed between two points also but both ends extend to infinity. A straight line is a figure formed when two points A (x1, y1) and B (x2, y2) are connected with the shortest distance between them, and the line ends are extended to infinity.
In the image shown below, a straight line between two points A and B is shown. A straight line AB is represented by: Vector AB
The lines are drawn in a slanting position or form some angle other than 0o, 90o, 180o, 270o, 360o with horizontal or vertical lines are called oblique or slanting lines.
y= -(x - 3)² + 2.
y= - (x2+9-6x)+2
y= -x2-9+6x+2
y= -x2-7+6x
y= -x2+6x-7
-y = x2+7x-x-7
-y= x(x+7)-1(x+7)
-y= (x+7)(x-1)

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as
editing) and variable costs (such as printing). The one-time fixed costs will total $32,060. The variable costs will be $12.75 per
book. The publisher will sell the finished product to bookstores at a price of $21.50 per book. How many books must the
publisher produce and sell so that the production costs will equal the money from sales?
In linear equations x = 3,664 books are the production costs will equal the money from sales .
What is a formula for linear equations?
A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. (b). Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.fixed cost = $32,060
variable cost = $12.75
here cost function
c(x) = fixed cost + x( variable cost )
c(x) = $32,060 + x($12.75) ................. 1
now revenue function
R(X) = (Selling price ).x
r(x) = ( 21.50)x .............2
where production cost is wqual to selling
c (X) = r (x)
32,0 60 + x($12.75) = ( 21.50)x
32,060 = ( 21.50)x - (12.75)x

Since both have f(x), the substitution method can be used.

2. f(x) = -10
Therefore,
-3x - 1 = -10
Flip to positive to calculate more easily since all are negative (although, this is optional.)

a rectangular piece of metal is 5in longer than it is wide, squares of 1in long are cut from the four corners and the flaps are folded upward to form an open box. if the volume of the box is 456in^(3) , what were the original demensions of the piece of metal?
The original dimensions (length and width) of this rectangular piece of metal are 19.81 inches and 14.81 inches respectively.
How to calculate the volume of a rectangular prism?Mathematically, the volume of a rectangular prism can be calculated by using this formula:
Volume = L × W × H
Where:
L represents the length of a rectangular prism.H represents the height of a rectangular prism.W represents the width of a rectangular prism.Given the following data:
Length, L = W + 5
Since squares of 1 in long are cut from the four corners, the length and width are reduced by 2 in. Also, the height of the box would be 1 inches.
Therefore, the volume of this rectangular box is given by:
456 = (L - 2) × (W - 2) × 2
456 = (W + 5 - 2) × (W - 2) × 2
456 = (W + 3) × (W - 2) × 2
228 = (W² - 2W + 3W - 6)
228 = W² + W - 6
W² + W - 6 - 228 = 0
W² + W - 234 = 0
Next, we would solve the quadratic equation by using the quadratic formula:
[tex]W = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}\\\\W = \frac{-1\; \pm \;\sqrt{1^2 - 4(1)(-234)}}{2 \times 1}\\\\W = \frac{-1\; \pm \;\sqrt{1 + 936}}{2}\\\\W = \frac{-1\; \pm \;\sqrt{937}}{2}[/tex]
Width, W = 14.81 or -15.81
Since the width cannot be negative, the value of W is equal to 14.81 inches.
For the length, we have:
Length, L = W + 5
Length, L = 14.81 + 5
Length, L = 19.81 inches.

Travis painted for 6 2/3 hours. He received $27 an hour for his work. How much was Travis paid for doing this painting job?
Answer:
$180
Step-by-step explanation:
Well because it is $27 per hour, you can start with the whole hours:
6*27=162
then because you are working with fractions you can find what 1/3 of 27 is:
27* (1/3)=9
this tells us that one-third of an hour is worth 9 dollars but because it is 2/3 then you just add another 9. This means 2/3 of 27 is 18.
Then you just add it all up:
162+18=180

The median of a quanitive data set is always one of the infiviual data values. True or false
The given statement "The median of a quantitative data set is always one of the individual data values" is false.
What is a median?When a given data set is arranged in ascending order the observation which at the between of the data is the median of that data set. It is a value in the set whose left and right both have the same number of observations.
The given statement is not true, this is because the median is the mid-value of any data set.
If the number of data observations is odd then the median of a quantitative data set is always one of the individual data values.But if the number of data observations is even then the median is the average of the two numbers present in between the data observations.Hence, the given statement "The median of a quantitative data set is always one of the individual data values" is false.
