For a repeated-measures study, a small variance for the difference scores indicates that the treatment effect is consistent across participants.
A. True
B. False
The statement that a small variance for the difference scores implies that the treatment effect is consistent is true
How to determine the truth value of the statement?The variance of a dataset is used to measure the spread and the average squared deviations from the mean of the dataset.
The smaller the variance of a repeated study, the closer the dataset set are from the mean of the dataset.
This means that a small variance indicates a consistent data
Hence, the given statement is true

Theresa uses a unique box in the shape of a trapezoidal prism for her specialty candles. The area of the base of the box for the smaller candle is 125 cm2 and the box is 12 cm tall. The box used for the larger candle has a base whose area is 160% that of the smaller box, and it is 6 centimeters taller.
What percent of the volume of the smaller box is the volume of the larger box?
Answer:
The volume of the larger box is 240% that of the volume of the smaller box.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables
Volume of smaller box = area of base * height = 125 cm² * 12 cm = 1500 cm³
Volume of larger box = area of base * height = (1.6 * 125 cm²) * (12 + 6) cm = 3600 cm³
Ratio of volume = 3600/1500 = 2.4 = 240%
The volume of the larger box is 240% that of the volume of the smaller box.

The Canvas Camping Company makes canvas tents like the one shown. How much material is needed to make the tent?
The material needed to make the tent assumes the shape of a triangular prism and the surface area of the material needed is 193.18 ft².
What is the surface area of a triangular prism?A triangular prism is indeed a three-sided prism made up of a triangle base, a translational copy, and triple faces connecting equivalent sides in geometry.
The properties of a triangular prism include:
It has five facesIt has six edgesIt has nine verticesLet's assume that the shape of the canvas tents is in form of a triangular prism, to determine the material needed to make the tent, we need to understand the surface area of a triangular prism.
However, let's assume that:
Each of the three bases of the triangular prism = 6The height of the triangular prism = 9From the image attached below: the surface area of the triangular prism can be calculated by using the following formula:
[tex]\mathbf{A = 2A_B +(a+b+c)h }[/tex]
[tex]\mathbf{A_B = \sqrt{s(s-a)(s-b)(s-c)}}[/tex]
[tex]\mathbf{s = \dfrac{a+b+c}{2}}[/tex]
Combining the formulas together the surface area of the triangular prism can be computed as:
[tex]\mathbf{S.A = ah+bh+ch+\dfrac{1}{2} \sqrt{ -a^4+2(ab)^2+2(ac)^2-b^4 +2(bc)^2-c^4}}[/tex]
[tex]\mathbf{S.A = (6\times9)+(6\times9)+(6\times9)+\dfrac{1}{2} \sqrt{ -6^4+2(6 \times 6)^2+2(6 \times 6)^2-6^4 +2(6 \times 6)^2-6^4}}[/tex]
S.A = 193.18 ft²

Consider a single spin of the spinner. a spinner contains 4 equal sections: 1, 2, 4 and 3. sections 1 and 4 are shaded. the spinner is pointed at number 2. which events are mutually exclusive? select two options. landing on a shaded portion and landing on an even number landing on a shaded portion and landing on a number greater than 3 landing on a shaded portion and landing on a 3 landing on an unshaded portion and landing on an odd number landing on an unshaded portion and landing on a number less than 2
Events that mutually exclusive are 1. Landing on a shaded portion and landing on a 3.2. Landing on an unshaded portion and landing on a number less than 2.
What is Mutually exclusive events?
Mutually exclusive events mean the events will have no intersection.
The two are options correct
1. Landing on a shaded portion and landing on a 3.
2. Landing on an unshaded portion and landing on a number
less than 2.
The explanation for 1:
Landing on a shaded portion means landing on 1 or 4.
Landing on 3 is not possible and it will be only on 3. So, these events have no intersection.
The explanation for second
Landing on an unshaded portion means landing on either 2 or 3. And landing on a number less than 2 means landing on 1.
There is no intersection.
So, these events are mutually exclusive.

Step-by-step explanation:
So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540
Then it is algebra
540=91+125+92+(3x-5)+(4x-8)
Simplify what you can and collect like terms
540=308+3x-5+4x-8
540=308+7x-13
Then move everything over to the one side so that the variable is isolated
540-308+13=7x
245=7x
242/7=x
35=x

For its 28th anniversary, an Uncles Game store is offering a 28% discount on all board games. What is the discounted cost of the game that regularly costs $32. 50?
Answer: $23.40
Step-by-step explanation:
We will find what percent of the normal cost the items are currently.
100% - 28% = 72%
Now, we will find 72% of $32.50
72% -> 0.72
$32. 0 * 0.72 = $23.40
The discounted cost is $23.40.
