The test that will allow you to analyze the differences in blood pressure between groups, after adjusting for age is the one way ANOVA test.
What is the test about?One-way analysis of variance is a statistical approach that can be used to determine if the means of two samples are substantially different or not. One-way ANOVA ("analysis of variance") examines the means of two or more independent groups to see if there is statistical evidence that the related population means differ significantly.
One-way ANOVA is commonly employed when there is a single independent variable, or factor, and the purpose is to determine whether fluctuations or various amounts of that factor have a measurable effect on a dependent variable. This van be used to illustrate the relationship.

An equation that shows the proportional relationship between cups (c) and tablespoons (n) is: B. c = 0.0625n
What is a proportion?A proportion is an equation which is typically used to indicate the equality of two (2) ratios. Therefore, proportions can be used in mathematics to show that two (2) ratios are equivalent and then used to calculate or determine all of the unknown quantities.
Mathematically, a proportional relationship can be represented by the following equation:
y = kx
Where:
y and x represent the variables in a proportional relationship.k is the constant of proportionality.Let the cups be represented by c.
Let the tablespoons be represented by n.
Next, we would determine the constant of proportionality (k) as follows:
c = kn
Making k the subject of formula, we have:
k = c/n
k = 0.5/8 ≡ 1.5/24
k = 0.0625.
Substituting the parameters into the equation for a proportional relationship, we have;
c = kn
c = 0.0625n

Can someone explain powers of imaginary numbers? (like i^2, i^3, i^4, and so on)
The powers of the imaginary number gives:
i² = -1i³ = -ii⁴ = 1i = i⁵i² = i⁶i³ = i⁷i⁴ = i⁸etc...
How the powers of imaginary numbers work?We know that the imaginary number is defined as:
i = √(-1)
If we square it, then we get:
i² = √(-1)² = -1
As the exponent 2 removes the square root.
With the exponent 3 we get:
i³ = √(-1)³ = √(-1)²*√(-1) = -1*i = -i
i³ = -i
Finally, the exponent 4 gives:
i⁴ = i²*i² = (-1)*(-1) = 1
And now the cycle repeats, we will have that:
i = i⁵
i² = i⁶
i³ = i⁷
i⁴ = i⁸
etc...

An appliance store decreases the price of a 19-in. television set 28% to a sale price of $455.76 What was the original price?
Answer:
$633.00Step-by-step explanation:
Let the initial price be x.
We have:
Decrease rate = 28%,Sale price = $455.76The price has decreased from x by 28% and become $455.76.
Set equation and solve for x:
x - 28% of x = 455.76x - 28x/100 = 455.76x - 0.28x = 455.760.72x = 455.76x = 455.76/0.72x = 633which one of these constructiond would construct a line of relection that takes the point A to point B
Option D is the constructions that would construct a line of reflection from point A to point B. Make a line parallel to line AB.
A line parallel to line AB will generate a line of reflection that connects points A and B because a parallel line never intersects, resulting in direct imagery of Line AB.
What is a Parallel lines?Parallel lines are two lines in the same plane that are equal distance apart and never intersect. They can be both horizontal and vertical in orientation.
We have,
-Make a perpendicular bisector of segment AB.
A perpendicular bisector does not create a line of reflection that connects points A and B, but rather divides the line AB into two equal parts.
-Draw a line through B that is perpendicular to segment AB.
A perpendicular line through B to segment AB WILL NOT Make a line of reflection from point A to point B.
-Build the line that connects A and B.
A line passing through A and B will NOT create a line of reflection that connects points A and B, but will instead create Line A and B and not its reflection.
Hence,
Make a line parallel to line AB.
A line parallel to line AB will generate a line of reflection that connects points A and B because a parallel line never intersects, resulting in direct imagery of Line AB.

What is an arithmetic sequence?An arithmetic sequence is one that is formed by the addition of a constant to the value of a term, to get the value of the next term.
1. The difference between the number of squares in subsequent figure is 5 - 3 = 7 - 5 = 2
Which gives;
The equation that gives the number of blocks in each figure is a linear equation of the form, y = m•x + c
Where;
m = The slope = The rate of change of the number of blocks = 2 more squares each subsequent figure
c = The y–intercept = The number of blocks when the figure is Figure 0 = The number of blocks at the start (The starting value)
Subtracting 2 (the slope) from the number of blocks in Figure 1, gives;
c = The starting value = Number of squares in Figure 0 = 3 - 2 = 1
Figure 0 has one square
Figure 4 has (2 × 4 + 1) blocks = 9 Squares
Figure 5 has (2 × 5 + 1) blocks = 11 Squares
Figure 100 has (2 × 100 + 1) blocks = 201 Blocks
2. Here, the slope, m = The rate of change = 3
The starting value, c = 6 - 3 = 3 = Figure 0
The number of blocks in each of the required figures are;
Figure 0 = 3 Squares
Figure 4 = 3 + 4 × 3 = 15
Figure 5 = 3 × 5 + 3 = 18
Figure 100 has (3 × 100 + 3) squares = 303 Squares
3. The slope, c = 7 - 5 = 5 - 3 = 2
The starting value = 3 - 2 = 1
Figure 0 has 1 block
Figure 4 has (2 × 4 + 1) blocks = 9 squares
Figure 5 has (2 × 5 + 1) blocks = 11 squares
Figure 100 has (2 × 100 + 1) blocks = 101 blocks
4. The number of blocks is (n + 1)²
The number of blocks increases by 2•n + 1
The slope = 2•n + 1
The starting value = 2×0 + 1 = 1
Figure 0 has 1 block
Figure 4 has (4 + 1)² blocks = 25 blocks
Figure 5 has (5 + 1)² blocks = 36 blocks
Figure 100 has (100 + 1)² blocks = 10,201 blocks

I hope this helps!
The system of equation 35x - 21y =10 and 5x-3y=2 has no solution , Option B is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equation is 35x - 21y =10 and 5x-3y=2
We can use elimination method to solve for x and y.
First, we can multiply the second equation by 7 to get:
35x - 21y = 10
35x - 21y = 14
Next, we can subtract the second equation from the first equation to eliminate the x terms:
35x - 21y - (35x - 21y) = 10 - 14
0 = -4
This is a contradiction, so there is no solution for x and y that satisfies both equations. The system is inconsistent.
Hence, the given system of equation 35x - 21y =10 and 5x-3y=2 has no solution , Option B is correct.

How much would you tip someone if the total cost of the meal is 13.40$?
The amount that you would tip someone if the total cost of the meal is 13.40$ is: $2.01.
How much is the standard tip in the United States?In the United States, the standard tip for good service is 15%. So, assuming that the meal service offered could be classified as a good service, we can say that 15% of 13.40$ will be the tip to provide.
15% of 13.40$ is equal to $2.01.
Therefore, the amount that the person who received the service is expected to pay is $2.01. Also, note that the tip for delayed service is 10% and the tip for excellent service is 20%. Bad service requires no tip.

- 75 - (- 67) = - 75 + 67 = - 8
- 83 - (- 75) = - 83 + 75 = - 8
thus to find the next 3 terms subtract 8 from the previous term

1/2Hd=d^2 solve for b
The solution of the equation for b is b= 2d²/H
What is subject of formula?This involves taking a variable in an equation to stand alone
Note that this variable is different from the initial isolated variable
How to determine the equation for b?The equation is given as
1/2Hb = d²
Divide both sides of the equation by H
So, we have the following equation
1/2Hb/H = d²/H
Multiply both sides of the equation by 2
So, we have the following equation
2 * 1/2Hb/H = d²/H * 2
Evaluate the quotients and the products
b= 2d²/H
The above computation implies that:
We changed the subject of the formula in the equation 1/2Hb = d² from d² to b
This implies that solving for b is a concept of subject of formula
