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

[tex] \frac{ \cos(x) + \sin(x) }{ \cos(x ) - \sin(x) } = \tan(45 + x) [/tex]
Answer:
First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...[tex]\frac{tan~x+1}{tan~x-1}[/tex]
Include 45 as one of the parameters and correlate with tan.[tex]\frac{tan~x+tan~45}{tan~x-tan~45}[/tex]
Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.Lastly, simplify, and you have the answer as tan(45 + x)research shows that the probability of a person being right handed is 0.77 how many left handed people would you expect in a population of 25000?

A function f(x) has x-intercepts of –3 and –5. what is the constant term in the function? f(x) = x2 8x
The constant term in the function f(x) = x² + 8x + 15 would be 15.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
A function f(x) has x-intercepts of –3 and –5 means
f(x) = (x+3)(x+5)
f(x) = a(x + 3)(x + 5), here a is a multiplier
let a = 1 then
f(x) = (x + 3)(x + 5) (expand factors)
f(x) = x² + 8x + 15
thus, 15 is the constant term

how many computers out of 220 can have errors and stay within the company's of no more than 2% errors
A. e<=2
B. e<=4
C. e<4
D. e<2
Hi maryanne!
Answer:
C. e<4
Step-by-step explanation:
Since [tex]\frac{e}{220} \leq 0.02[/tex]
e [tex]\leq[/tex] 0.02 x 220
e [tex]\leq[/tex] 4.4 (multiply 220 both sides)

A sequence can be generated by using an=an−1+2, where a1=8 and n is a whole number greater than 1.
What are the first 3 terms in the sequence?
a) 8, 10, 12
b) 8, 16, 32
c) 2, 16, 128
d) 2, 10, 18
The sequence an=an−1+2 is an arithmetic sequence
The first three terms in the sequence are (a) 8, 10, 12
How to determine the first three terms?The sequence is given as:
an=an−1+2
Where:
a1 =8
Start by calculating a2 using:
a2=a1+2
This gives
a2=8+2 = 10
Calculate a3 using:
a3=a2+2
This gives
a3=10+2 = 12
So, we have:
a1 = 8, a2 = 10 and a3 = 12
Hence, the first three terms in the sequence are (a) 8, 10, 12

A figure is composed of two cubes. The side lengths of the larger cube are twice the side length of the smaller cube. If the total volume of the cubes is 1,944 m3, what are the side lengths of the two cubes? Enter the smaller dimension first
The side lengths of the two cubes are 6 meters and 12 meters respectively.
How to calculate the volume of a cube?Mathematically, the volume of a cube is calculated by using this following formula:
Volume = m³
Where:
m is the side lengths of a cube.
Translating the word problem into an algebraic expression, we have;
m³ + (2m)³ = 1944
m³ + 8m³ = 1944
9m³ = 1944
m³ = 1944/9
m = ∛216
m = 6 meters.
For the bigger cube:
2m = 2 × 6
2m = 12 meters.

Which of the following is a Pythagorean triple?
Answer:
C: 8, 15, 17
Step-by-step explanation:
The easiest way to do this is simply to memorize the first few Pythagorean triples. It saves time. But it can also be hard to remember that. To see if something is a triple...
1. [tex]a^{2} + b^2=c^2[/tex]. This means square the first one, the second and add. Then square the last one. The sum of the first two with the last one should be the same.
2. For this to work, they have to be in order from least to greatest. All of these are.
3. Let's fill in the equation:
8^2= 64.
15^2= 225.
225+64= 289
17^2= 289.
It matches! It's a triple.

The sphere of mass m and radius r is rigidly attached to a thin rod of radius r that passes through the sphere at distance 12r from the center. A string wrapped around the rod pulls with tension t.
The expression for the angular acceleration of the sphere will be 20Tr/13MR².
What is angular acceleration?It should be noted that angular acceleration simply means the time rate of change of the angular velocity.
From the information given, I = (2/5(MR² + M(R/2)² = MR²(2/5 + 1/4) = 13MR²/20
The torque (Q) will be Tr. Therefore, the expression for the angular acceleration of the sphere will be:
= Q/I
= Tr/13MR²/20
= 20Tr/13MR²
