Answer:
I believe the answer is 10x + 6
Step-by-step explanation:
well we know that the same length and width of a rectangle is twice . this means that you can multiply the length and width by 2 to get the perimeter and add them . so by foiling you will have 2(3x+4) + 2(2x-1). you can solve this and simplify it to get 6x + 8 + 4x - 2 . simplify this more to get 10x + 6.
I'm a little confused because I do not see an answer on your question that says 10x + 6 . can you add a diagram, formatting, or more context if I am wrong?
a researcher could be examining what percentage of golfers buy only titleist balls, or might be looking at what percentage of high school students buy from taco bell between meals. in either case, the mean or percentage is derived from a sample, so it is:
The mean and percentage is deduced from a sample in either case, so it is: the statistic for the sample.
What is defined as the sample statistic?A sample statistic (or simply statistic) is any number calculated from the sample data. The sample median, average, sample standard deviation, as well as percentiles are some examples. Because it is based on data acquired through random sampling, a type of random experiment, a statistic is a random variable. As a result, a statistic is both known and random.For the given question,

(4,-2) does not lie on the line
Here, we want to select the point that is not a solution to the graphed line
What we have to do is just to susbtitute the value of x and y. If by aritjmetic operation, the result is 16, then the point lies on the line
We proceed as follows;
a) (4,-2)
-2(4) -4(-2)
-8+8 = 0
This lies on the line
b) (1, -4.5)
-2(1)-4(-4.5) = -2 + 18 = 16
This is not on the line
c) (-2,-3)
-2(-2)-4(-3) = 4 + 12 = 16
d) -2(-5)-4(-1.5)
= 10 + 6 = 16
As we can see, only the first point does not lie on the line

Without solving for x, how can you show that x=2 is a solution to 2x+3=3x+1?
We minus 3 on both sides, we get :
2x = 3x - 2
We have the equation : 3x - x = 2x, or 2x = 3x - x, and this holds true.
Since x corresponds to 2 in the first equation, x = 2 is a solution

WILL MARK BRAINILEST!!
Assuming you're trying to find the value of r...
Answer:
r = 1
Step-by-step explanation:
Take your starting equation:
16 = 16r
Since r is multiplied by 16, divide both sides by 16 to isolate r.
16 / 16 = 1
16r / 16 = r
The result is 1 = r, which can be written as:

Step-by-step explanation: Out of the 50 times the coin was flipped, it landed on tails 35 times. This means it landed on heads 15 times (50-35=15). The ratio of heads to the total number of flips would be 15:50.
Stella walks down a flight of stairs to the basement. Then she walks back up the stairs and another flight of stairs to the second floor of her house. Each flight of stairs represents a change of 12 feet in height. How far is Stella above the ground
If Stella walks down a flight of stairs to the basement. Then she walks back up the stairs and another flight of stairs to the second floor of her house. How far is Stella above the ground is: 12 ft.
Height above the groundGiven:
Flight stair = 12 feet
Hence,
Let walking from down a flight of stairs to the basement = -12 f
Let walking back up the stairs = 12Ft
Now let determine Stella height above the ground.
Height = -12 feet + 12 feet + 12 feet
Height = 12 feet

When the plane reaches an altitude of 2,000 ft temperature will be 59.3F
What is altitude?The height of a thing above the surface of a planet or natural satellite, like the sea or land is known as altitude.A distance measurement between a reference datum and a point or object, typically in the vertical or "up" direction, is known as altitude, height, or depth.
Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction.
For every 1000 ft there is a drop of 1.2 Fahrenheit
∴ for 2000ft drop in temperature of 2×1.2=2.4F
Also the temperature on the ground is 61.7F
The temperature when the plane reaches 2,000 ft will be

Using the binomial distribution, there is a 0.6328 = 63.28% probability that she wins at most 1 prize.
For each box, there are only two possible outcomes, either it has a prize, or it does not. The probability of a box having a prize is independent of any other box, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
x is the number of successes.
n is the number of trials.
p is the probability of a success on a single trial.
In this problem:
She buys 5 boxes, hence
1 in 4 boxes has a prize, hence
The probability is:
P ( X ≤ 1 ) =P ( X = 0 ) + P ( X = 1 )
Then ,
P ( X ≤ 1 ) = P ( X = 0 ) + P ( X = 1 )
= 0.2373 + 0.3955

Jon used a gift card to pay for an $17 shirt.The remaining balance on the card is $31.Write and solve an equation that representsthis.
Answer
The initial amount on Jon's giftcard is $48.
Explanation
Let the initial amount on Jon's gift card be x dollars.
Jon pays $17 for a shirt using the gift card and the remaining balance was $31.
That is, the equation representing this is
x - 17 = 31
To solve this, we add 17 to both sides
x - 17 + 17 = 31 + 17
x = 48 dollars
The initial amount on Jon's giftcard is $48.
Hope this Helps!!!
Good evening,
Answer: x-17=31 is the equation you're looking for meanwhile its result is x=48
Explanations: Jon spent $18 after having $31 on the card so they're spending money off the card, therefore the equation you're loooking for is x-17=31. In order to solve it add 17 to the other side of the equation such as:
x-17=31 ; x=31+17 ; x=48

Point B has coordinates (5,1). The x-coordinate of point A is −3. The distance between point A and point B is 10 units. What are the possible coordinates of point A?
The possible coordinates of the point A is (-3, -5) and (-3, 7)
How the coordinates of point A can be calculated?The given parameters are:
Point B = (5, 1)Distance between the two points, D = 10 unitsx-coordinate of point A = −3This means that
A = (-3, y)
The distance between any two points is calculated as
D = √[(x₁ - x₂)² + (y₁ - y₂)²]
Substitute the known values in the above equation
So, we have
10 = √[(-3 - 5)² + (y - 1)²]
Evaluate the difference
10 = √[(-8)² + (y - 1)²]
Take the square of both sides
100 = (-8)² + (y - 1)²
So, we have
100 = 64 + (y - 1)²
Evaluate the like terms
(y - 1)² = 36
Take the square roots
y - 1 = ±6
This gives
y = 1 ± 6
So, we have
y = -5 and 7
Hence, the coordinates of point A is (-3, -5) and (-3, 7)

the ages of students at a university are normally distributed with a mean of 23. what percentage of the student body is at most 23 years old?
By the concept of mean ,50% of the student body is at most 23 years old.
What is mean?In mathematics, particularly in statistics, there are various kinds of means. Each mean is used to summarize a certain set of data, frequently to help determine the overall significance of a particular data set. Two easy steps can be used to determine the mean, or average, of a set of data: Add up all of the values to get the sum. Divide the total by the total number of values in the data collection. A data set's mean (average) is determined by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint number. The number that appears most frequently in a set of data is called the mode.
