Answer:
11 , 17 , 24
Step-by-step explanation:
• Since the Lowest number is 11 and the range is 13 then
The greatest number is 11 + 13 = 24
• Therefore the three numbers are 11 , 17 and 24
because the median of the set 11 , 17 , 24 is 17

In order to slove the following system of equations by addition, which of the following could you do before adding the equations so that one variable will be eliminated when you add them?
4x-2y=7
3x-3y=15
Answer:
B. use multipliers -3 and 2
Step-by-step explanation:
If you're solving the system by "addition," multiplying the equations by the chosen numbers needs to result in opposite coefficients for one of the variables.
Effect of answer choicesA. The system becomes ...
12x -6y = 2112x -12y = 60No variable has opposite coefficients.
__
B. The system becomes ...
-12x +6y = -216x -6y = 30The y-variable has opposite coefficients. This is a good choice.
__
C. The system becomes ...
12x -6y = 216x -6y = 30No variable has opposite coefficients.
__
D. The system becomes ...
4/3x -2/3y = 7/33x -3y = 15No variable has opposite coefficients.
__
Additional comment
The simplest "no brainer" solution is to use the coefficients of one of the variables, negating one of them. Multiply each equation by the opposite equation's coefficient. Here, the y-coefficients are -2 and -3, and the multipliers of answer choice B are -3 and 2, consistent with this advice. (The sign of 2 was changed.)
Answer:
B.
Step-by-step explanation:
Multiply the top equation by -3 and the bottom equation by 2

A credit card company charges a 4% balance transfer fee. If you want to transfer a balance of $2,100 to this credit card, what fee would you pay?
Answer:
$84
Step-by-step explanation:
So since it charges 4%, this means you need to find 4% of what you're transferring. To find x% of a number, you need to convert the percentage to a decimal, and then multiply it by the number you're trying to find x% of. So in this case 4%/100 = 0.04. Now take this decimal and multiply it by 2100, and this will give you 84. So the fee would be $84
Answer:
$84
Step-by-step explanation:
= 4% × $2100
= 0.04 × $2100

Which could be the entire interval over which the
function, f(x), is positive?
O (-∞, 1)
O (-2, 1)
O (-∞, 0)
O (1,4)
Answer:
(-2, 1)
Step-by-step explanation:
So assuming this table contains all the zeroes of f(x) and all of them having a multiplicity of 0. This quadratic equation can be defined as
[tex]f(x) = a(x+2)(x-1)[/tex]. So if you look at the top where its f(-3) then f(-2) then f(-1) it appears to be increasing and then somewhere in between f(-1) and f(0) it has a turning point in which it starts decreasing. and then after f(1) it no longer outputs positive values and appears to be going towards negative infinity. So the interval in which f(x) is positive seems to be finite and using this table it appears to be at (-2, 1) and make sure to use parenthesis since at f(-2) and f(1) it's not positive, because 0 is not positive, so it's not included in the interval

Hello!
We can determine if it's a solution by plugging in the x and y-values of the point into the equation. If both sides are equal to each other, then it is a solution.
-3 is the x-value and -5 is the y-value, since an ordered pari is written in the form of (x,y).
Evaluate7x - 5y = 157(-3) - 5(-5) = 15-21 + 25 = 154 ≠ 15Since both sides are not equal to each other, (-3,-5) is not a solution.
The Green Party at a large university plans to line both sides of a 24-foot-long hallway with posters endorsing a candidate for state senate. Each of the posters costs them $6.25 , they’re 3 feet wide, and there will be 4 feet between posters. Assume the first poster on each end will be exactly even with the start of the hall. Estimate how much this will cost.
The total cost of putting the posters on the wall is $25.
What is the cost of putting the posters on the wall?
If the first poster on each end will be exactly even with the start of the wall, it means that after the two posters have been placed on either side of the wall, the total space left would be 10 feet (24 - 3 - 3 - 4 - 4).
After the first poster has been placed on both ends of the wall, a second poster would be placed on either ends of the wall. Total space now left is 4 feet (10 - 3 - 3). So there can only be four posters on the wall.
Total cost of 4 posters = 4 x $6.25 = $25

Please help!! Very much appreciated!! Consider the following set of real numbers. Which of the following lists all of the rational numbers in the set?
Answer:
The second choice.
Step-by-step explanation:
A rational number means that you are able to write the number as a fraction with integers in the numerator and the denominator. An integers are the whole numbers and their opposites ...-3,-2,-1,0,1,2,3...
The square root of 4 is 2. 2 can be written 2/1 (an integer over and integer)
-square root of 2 cannot be written as an integer over an integer. When this number is written as a decimal number it never repeats and it never terminates so it cannot be written as an integer over and integer.
-2/3 is written in the form of an integer over and integer.
1 can be written 1/1
9/8 is written as an integer over an integer.
The square root of 9/4 would be 3/2. (3/2)(3/2) = 9/4.
2.4 repeating can be written as an integer over an integer. Any decimal that repeats or terminates can be written as an integer over and integer. It actual happens to be 22/9.
The square root of 10 written as a decimal does not repeat or terminate so it is not rational. Only perfect squares are rational.

Answer:
0.29287
Step-by-step explanation:
You want to use the binomial cumulative distribution function (binomcdf). The purpose of this function is that it allows you to obtain the probability of observing less than or equal to x successes in n trials, with the probability p of success on a single trial.
x in this case is 182, n is 200, and p is 0.9005. Essentially by inputting these values, we find the probability that out of 200 passengers with a 0.9005 chance of getting on the plane, that 182 or less show up.
This gives us P(x <= 182) = 0.70713. (You need your calculator for this step, input the values above in the binomcdf function)
We want to find the probability of more than 182 passengers showing up though, so it would be 1 - 0.70713 = 0.29287.
Thus the probability that when 200 reservations are accepted for the flight, there are more passengers than seats available is 0.29287.
A container is shaped like a cylinder with half spheres on each end. The cylinder has a length of 30 centimeters and a radius is 5 centimeters. To the nearest cubic centimeter, how many cubic centimeters can one container hold? Do not round calculations until the final answer. For the final answer, round to the nearest cubic centimeter (no decimals) and use a comma to separate the thousands place. cubic centimeters
The cubic centimeter one container can hold is 2,878.33 cm³.
What is the cubic centimeter one container can hold ?In order to determine the cubic centimeter one container can hold, the volume of the container has to be determined.
Volume of the container = volume of the cylinder + (2 x volume of the hemisphere)
Volume of the cylinder = πr²h
Where:
π = 3.14 r = radius h = height3.14 x 5² x 30 = 2355 cm³
Volume of a hemisphere = (2/3) x π x r³
2 x (2/3 x 3.14 x 5³) = 523.33 cm³

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the rule of three is given as follows:
8 days - 15 men - 240 meters

Answer: Choice C
(0.5, 5.5)
===========================================================
Explanation:
Draw out a number line with -2 and 3 on it. These are the x coordinates of the given points. Add up these values and divide by 2 to get the midpoint on the number line.
(A+B)/2 = (-2+3)/2 = 1/2 = 0.5
The value 0.5 is the midpoint of -2 and 3. This midpoint is equally spaced from both endpoints.
Therefore, the x coordinate of the midpoint is 0.5
Repeat this idea for the y coordinates
Add: 4 + 7 = 11
Divide the result in half: 11/2 = 5.5
The y coordinate of the midpoint is 5.5
The overall midpoint itself is located at (x,y) = (0.5, 5.5)
This is why choice C is the final answer.
Visual confirmation is shown below. GeoGebra has a nice handy feature to find the midpoint very quickly with just a few clicks.
