Step-by-step explanation:
A teacher has two large containers filled with blue, red, and green beads, and claims the proportions of red beads are the same in each container. Each student shakes the first container, selects 50 beads, counts the number of red beads, and returns the beads to the container. The student repeats this process for the second container. One student’s samples contained 13 red beads from the first container and 16 red beads from the second container.
Based on the 95% confidence interval, (–0.24, 0.11), is the teacher’s claim justified?
The teacher’s claim is not justified because the two sample proportions are different.
The teacher’s claim is not justified because the interval contains both positive and negative values.
The teacher’s claim is justified because the interval contains 0, meaning there is no difference in the proportions of beads in each container.
The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Answer:
D. The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.
Explanation:
100%
Answer: The teacher’s claim might not be justified because the interval contains both positive and negative values. It is plausible that the proportion of red beads in each container is different.

Find the slope of the line that passes through (10, 4) and (3, 1).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
(3,-9)
Step-by-step explanation:
sorry if its wrong i tried...
(10,4),(3,1)
Subtract the y-coords, then the x-coords.
4-1=3
10-3=7
The slope is 3/7. Let me know if you need help graphing it too.
3 is the rise and 7 is the run. You start at (0,0) and you go up 3 units, then 7 units right. The first coordinate should be (7,3). Repeat until you have a straight line.

Each gallon of paint covers $200$ square feet. I have to paint one side of a wall that is $12$ meters tall and $80$ meters long. If a foot is approximately $0.3048$ meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?
The smallest whole number of gallons require to paint the wall is 52 gallons.
Given that, 1 gallon of paint = 200 ft², 1 foot = 0.3048 meters and dimension of wall is 12 meter by 80 meter.
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Converting the dimension to feet :
12/0.3084 = 39.370078 feet
80/0.3084 = 262.46719 feet
Hence, the area of the wall is
Area = Length × width
Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²
Let number of gallons required = x
Since, 1 gallon = 200 ft²
x gallons = 10093.516 ft²
Cross multiply :
200x = 10093.516
x = 10333.35374274082/200
x = 51.6667687137041 gallons
x = 52 gallons
Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint.

Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle.

What is the decimal multiplier to increase by 6.1%?
first add or subtract the percentage from 100 ,then convert to a decimal.
What is a simple definition of the multiplier?
It is the number of times a rise in national income exceeds the rise in injections of demand that caused it.
What is the multiplier process?
The multiplier effect comes about because injections of new demand for goods and services into the circular flow of income stimulate further rounds of spending – in other words “one person’s spending is another’s income”
This can lead to a bigger eventual final effect on output and employment.

$9,800,000 is what percent of $7,000,000
Answer:
686000000000
Step-by-step explanation:
1. We assume, that the number 7000000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 7000000 is 100%, so we can write it down as 7000000=100%.
4. We know, that x is 9800000% of the output value, so we can write it down as x=9800000%.
5. Now we have two simple equations:
1) 7000000=100%
2) x=9800000%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
7000000/x=100%/9800000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 9800000% of 7000000
7000000/x=100/9800000
(7000000/x)*x=(100/9800000)*x - we multiply both sides of the equation by x
7000000=1.0204081632653E-5*x - we divide both sides of the equation by (1.0204081632653E-5) to get x
7000000/1.0204081632653E-5=x
686000000000=x
x=686000000000
now we have:
9800000% of 7000000=686000000000
Cam hit the bull's-eye in darts 8 times out of 15 throws. What is the experimental probability that cam's next throw will hit the bull's-eye?
Answer:
[tex]Probability = 0.533[/tex]
Step-by-step explanation:
Given
[tex]Hits = 8[/tex]
[tex]Throws = 15[/tex]
Required
Determine the experimental probability
This is calculated by dividing the number of hits by the total throws.
[tex]Probability = \frac{Hits}{Throws}[/tex]
[tex]Probability = \frac{8}{15}[/tex]
[tex]Probability = 0.533[/tex]

Answer:
324m^2
Step-by-step explanation:
To find the surface area, you have to find the area of all the sides of the prism. First of all, let's find the measurements of the numbers we already see.
base: 6x16= 96
front: 6x3=18
side: 16x3=48
Now we have these three numbers. Because it says to find the surface area, You can see that each of these numbers has to be doubled because, for the base, there is also a ceiling to it. For the sides, there are two sides. for the front, there is also a back. This is why you have to double all these numbers.
96x2= 192
18x2= 36
48x2= 96
Now add them all
192+36+96=324
hence, the surface area of this prism is...
324m^2
Hope this helps! '∆'
Answer:
3*16*6=288 m
Step-by-step explanation: Because a rectangular prism has six rectangular faces or sides, its surface area is just the sum of the six faces, and because each face has an identical opposite, you can calculate the surface area with the formula 2 * length * width + 2 * width * height + 2 * height * length. Also, Multiply the area of the rectangular base face times the height. Simply multiply the area of the base times the height. After you multiply the base and height, you'll have the volume of the rectangular prism. State your answer in cubic units.

List four rational numbers between -1 and 0
Answer:
4 rational numbers between -1 and 0 are;
(-¼, -½, ¼, ⅜)
Step-by-step explanation:
Rational numbers between two numbers say x and y is given by;
(x + y)/2
Thus;
Rational number between -1 and 0 = (-1 + 0)/2 = -1/2
Rational number between 0 and -1/2 = (-½ + 0)/2 = - 1/4
Rational number between 1 and -1/2 = (-½ + 1)/2 = 1/4
Rational number between 1 and -1/4 = (-1/4 + 1)/2 = ⅜
Thus,4 rational numbers between -1 and 0 are;
(-¼, -½, ¼, ⅜)
