You paint four walls. Each wall is a rectangle with a length of 20 feet and a height of 12 feet. One gallon of paint covers about 320 square feet. How many gallons of paint do you need in order to cover the walls?Give explanation
Answer:
To find out how many gallons of paint are needed to cover the walls, we need to first find the total area of the walls.
The four walls are rectangles with a length of 20 feet and a height of 12 feet. So, the area of one wall is:
20 feet x 12 feet = 240 square feet
Since there are four walls, the total area of the walls is:
4 x 240 square feet = 960 square feet
We know that one gallon of paint can cover approximately 320 square feet. To find how many gallons of paint are needed, we can divide the total area of the walls by the area covered by one gallon of paint:
960 square feet ÷ 320 square feet per gallon = 3 gallons of paint
Therefore, you need approximately 3 gallons of paint to cover the walls.
Which of the following is the best example of a defined benefits plan?
O a set amount an employee will receive at retirement
O the wages and benefits an employee receives at a job
O the amount of pay an employee receives each hour
O the money the an employer puts into a retirement fund for each employee
Answer:
The best example of a defined benefits plan is: "a set amount an employee will receive at retirement".
In a defined benefits plan, the employer promises to pay employees a specific, predetermined amount of money upon retirement. This amount is typically based on factors such as the employee's salary and years of service. The employer is responsible for contributing to and managing the retirement fund, and the employee receives a guaranteed amount of money upon retirement, regardless of how the fund performs.
The other options listed are not examples of defined benefits plans. The wages and benefits an employee receives at a job are part of their compensation package and may include retirement benefits, but they do not guarantee a specific amount of money at retirement. The amount of pay an employee receives each hour is their hourly wage and is not related to retirement benefits. The money an employer puts into a retirement fund for each employee may be part of a defined benefits plan, but it is not a complete plan in and of itself.
Which operation can we use to solve for x in the equation 12+x=15?
A) Add 12 to both sides of the equation
B) Divide both sides of the equation by 12
C) Multiply both sides of the equation by 12
D) Subtract 12 from both sides of the equation
Answer:
Subtract 12 from both sides of the equation
Step-by-step explanation:
Solve for x:
12+x=15
-12 -12
x = 3
Brainlist please.
Answer:
D) Subtract 12 from both sides of the equation.
To solve for x in the equation 12 + x = 15, we need to isolate the variable x on one side of the equation. We can do this by subtracting 12 from both sides of the equation, which gives:
12 + x - 12 = 15 - 12
x = 3
Therefore, the solution for x is 3.
he life expectancy of a typical lightbulb is normally distributed with a mean of 1,975 hours and a standard deviation of 25 hours. What is the probability that a lightbulb will last between 1,950 and 2,050 hours
The probability that a lightbulb will last between 1,950 and 2,050 hours is 0.84, or 84%.
To solve this problem, we need to find the probability that the lifespan of a lightbulb will fall between 1,950 and 2,050 hours.
First, we need to standardize the distribution using the z-score formula:
z = (x - μ) / σ
where x is the value we are interested in, μ is the mean, and σ is the standard deviation.
For x = 1,950 hours:
z = (1,950 - 1,975) / 25 = -1
For x = 2,050 hours:
z = (2,050 - 1,975) / 25 = 3
Now, we need to find the area under the standard normal distribution curve between z = -1 and z = 3. We can use a standard normal distribution table or a calculator to find this area.
Using a standard normal distribution table, we find that the area to the left of z = -1 is 0.1587 and the area to the left of z = 3 is 0.9987. Therefore, the area between z = -1 and z = 3 is:
0.9987 - 0.1587 = 0.84

Box plot, as the median can be easily ascertained from the substantial amount of data. The answer is option (a).
What is a median?The middle value in a given set of figures or statistics is referred to as the median. The average value for a given collection of integers can be calculated using one of three main methods in mathematics. The mean, the median, and the mode are the three. Central tendency measurements refer to these three factors. The average value of the supplied data is calculated using mean. The midpoint value of the given data is defined by a median. The input data's repeating value is defined by the mode.
A box plot is a very visual way to show a brief summary of one or more sets of data. It is particularly useful for quickly comparing and summing multiple sets of findings from distinct trials. A box plot provides a visual picture of the distribution of results as well as clues regarding data symmetry at a look.

Round the answers to at least three decimal places. A 99.9% confidence interval for the mean weight is <<μ.
The 99.9% confidence interval for the mean weight is (14.042, 14.202).
What is statistics?
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.
To construct a 99.9% confidence interval for the mean weight, we can use the formula:
CI = X ± Zα/2 * (σ/√n)
where X is the sample mean, Zα/2 is the critical value from the standard normal distribution corresponding to a 99.9% confidence level (which is 3.291), σ is the population standard deviation (which we don't know, so we will use the sample standard deviation as an estimate), and n is the sample size.
First, we need to calculate the sample mean and sample standard deviation:
X = (14.07 + 13.99 + 14.16 + 14.17 + 14.15 + 14.11 + 14.24 + 13.99 + 14.14 + 14.13 + 14.20 + 14.21 + 14.06 + 14.05) / 14 = 14.122
s = sqrt((1/(n-1)) * ∑(xᵢ - X)²) = 0.072
where n is the sample size and ∑(xᵢ - X)² is the sum of squared deviations from the sample mean.
Plugging in the values, we get:
CI = 14.122 ± 3.291 * (0.072/√14) = (14.042, 14.202)
Therefore, the 99.9% confidence interval for the mean weight is (14.042, 14.202).

a) 11:00 pm.
b) midnight.
c) 1:00 am. d) 2:00 am. e) 3:00 am
Your answer is option b)
The time at which a star rises shifts approximately 4 minutes earlier each day, due to Earth's orbit around the Sun. Since there are roughly 30 days in a month, we can calculate the change in the rise time of Aldebaran over the course of a month.
Step 1: Calculate the time change over one month
30 days * 4 minutes per day = 120 minutes
Step 2: Convert minutes to hours
120 minutes ÷ 60 minutes per hour = 2 hours
Step 3: Subtract the time change from the current rise time
2:00 am - 2 hours = 12:00 am (midnight)

A two-digit number is less than 6 times the sum of its digits by 1. The difference between the digit is 1. Find the number.
Answer:
the two-digit number is 65.
Step-by-step explanation:
Let's assume that the tens and units digits of the two-digit number are x and y, respectively.
According to the given condition,
10x + y < 6(x + y) - 1 (less than 6 times the sum of its digits by 1)
Simplifying the above equation, we get:
4x - 5y < -1 (dividing both sides by 2)
Also, it is given that the difference between the digits is 1, so we can write:
x - y = 1 (difference between the digits is 1)
Now, we need to solve these two equations to find the values of x and y.
Multiplying the second equation by 4, we get:
4x - 4y = 4
Adding this equation to the first equation, we get:
4x - 5y + 4x - 4y = 3
Simplifying the above equation, we get:
8x - 9y = 3
Now, we can solve these two equations simultaneously to find the values of x and y.
Multiplying the second equation by 8, we get:
8x - 8y = 8
Subtracting this equation from the previous equation, we get:
y = 5
Substituting this value of y in the equation x - y = 1, we get:
x - 5 = 1
x = 6
Therefore, the two-digit number is 65.

Step-by-step explanation:
to find the area of the figure you must do the area of the small rectangle plus the area of the large rectangle
area = length* width
so the area of the small rectangle equals
7ft * 4ft = 28ft²
then the large rectangle
9ft*8ft=72ft²
28ft²+72ft²=100ft²

How to find interpret the scatter plot?The formula for the equation of a line formed by 2 coordinates is;
(y2 - y1)/(x2 - x1) = (y - y1)/(x - x1)
Using the coordinates (30, 127) and (35, 139), we have;
(139 - 127)/(35 - 30) = (y - 127)/(x - 30)
12/5 = (y - 127)/(x - 30)
12(x - 30) = 5(y - 127)
12x - 360 = 5y - 635
5y = 12x + 275
Thus, when the height is y = 187 cm, we have;
5(187) = 12x + 275
935 = 12x + 275
12x = 935 - 275
12x = 660
x = 660/12
x = 55 cm

5. 5 boys and 5 girls sit in a row in a random order (each order is equally likely). what is the probability that no two people of the same sex sit next to each other?
the probability that no two people of the same sex sit next to each other is 2/7.
One way to solve this problem is to use the principle of inclusion-exclusion. Let A be the event that the boys sit next to each other, and let B be the event that the girls sit next to each other. Then, we want to find the probability of the complement of (A or B), which is the probability that neither A nor B occurs.
The probability of A occurring is the same as the probability of the 5 boys sitting in a row, which is 5! (since each order is equally likely). Similarly, the probability of B occurring is 5!. However, we need to subtract the probability of A and B occurring simultaneously. This can be seen as follows: once the boys are seated in a row, there are 6 spaces (between or on the ends) where the girls can be seated. Thus, the probability of A and B occurring is 2*5!*6.
Therefore, the probability of neither A nor B occurring (i.e., the probability that no two people of the same sex sit next to each other) is:
P(neither A nor B) = 1 - P(A or B) = 1 - [P(A) + P(B) - P(A and B)]
= 1 - [(25!) / 10! - (25!6) / 10!]
= 1 - [25!*(1 - 6/9!)]
= 2/7

what is the probability that a random integer from 91 to 775 is divisible by 14? (all integers in the given range are equally likely to be chosen).
Answer:
There are 775 - 91 + 1 = 685 integers.
In the given range, the smallest multiple of 14 is 98, and the largest multiple of 14 is 770. ((770-98)/14) + 1 = 49 multiples of 14.
So the probability of choosing a multiple of 14 from this range is 49/685.
