John wants to hit homeruns for his baseball team. He wants to be within 5 homeruns of hitting 30 for the year. Write an absolute value equation of the given situation.
He wants to be within 5 homeruns of hitting 30 for the year, therefore he needs 25 home runs.
How to illustrate the information?From the information, it was stated that John wants to hit homeruns for his baseball team and that he wants to be within 5 homeruns of hitting 30 for the year.
Let the number of home runs be represented by x.
Therefore, x + 5 = 30
x = 30 - 5
x = 25
Therefore, since he wants to be within 5 homeruns of hitting 30 for the year, he needs 25 home runs.

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
Answer:
x² + (y – 3)² = 36
and
x²+ (y + 8)²= 36
Step-by-step explanation:
The equation of circle that has a center (a, b) is given by the formula
(x - a)² + (x - b)² = r²
where r is the radius of the circle
If the circle lies on the y axis, its x-coordinate must be 0.
The radius of the circle = 1/2 x diameter = 1/2 x 12 = 6 units
So the equation must be of the form
(x - 0)² + (y - b)² = 36
We can eliminate x² + (y – 5)² = 6
We can also eliminate (x + 6)² + y² = 144
That leaves us with the two possible equations
x² + (y – 3)² = 36 (center at 0, 3)
and
x²+ (y + 8)²= 36 (center at (0, -8) )
Write an equation in slope-intercept form for each table below. Show how you found the slope and y-intercept.
The linear functions for the tables given are as follows:
1. y = 2.5x.
2. y = x + 1.
3. y = 3x - 1.5.
4. y = -4x + 3.
5. y = 4x + 1.
What is a linear function?A linear function is modeled in slope-intercept form by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For each function, the slope and the intercept are found as follows:
For item 1, when x = 0, y = 0, hence the intercept is of b = 0. When x increases by 1, y increases by 2.5, hence the slope is of m = 2.5.For item 2, when x = 0, y = 6, hence the intercept is of b = 1. When x increases by 1, y increases by 1, hence the slope is of m = 1.For item 3, when x = 0, y = -1.5, hence the intercept is of b = -1.5. When x increases by 1, y increases by 3, hence the slope is of m = 3.For item 4, when x = 0, y = 3, hence the intercept is of b = 3. When x increases by 1, y decreases by 4, hence the slope is of m = -4.For item 5, when x = 0, y = 1, hence the intercept is of b = 1. When x increases by 1, y increases by 4, hence the slope is of m = 4.Hence the functions are given as follows:
1. y = 2.5x.
2. y = x + 1.
3. y = 3x - 1.5.

The mass of a paperclip is 7.0 * 10^(-4) mg. If a box of paper clips has (3.18 10^(4) paper clips, determine the total mass of the paper clips in the box. Write the final answer in scientific notation with the correct number or significant digits.
2.2 * 10^1 mg
2 * 10^1 mg
2.226 * 10^1 mg
2.23 * 10^0 mg
The total mass of the paper clips in scientific notation is 2.226*10 mg
How to get the total mass of the paper clips?
We know that the mass of a single paper clip is:
M = 7.0*10⁻⁴ mg
And in one box has a total of 3.18*10⁴ clips inside of it, then the total mass of the paper clips on the box will be equal to the product between the mass of a single clip and the total number of clips.
We will get:
total mass = (7.0*10⁻⁴ mg)*(3.18*10⁴)
Using the associative property we can rewrite:
total mass = (7.0*3.18)*(10⁻⁴*10⁴) mg
= (22.26)*(10⁰) mg = 22.26 mg
Now we want to write this in scientific notation, so we need to have a single digit in the left of the decimal point, then we can rewrite this as:
22.26 mg = 2.226*10 mg

Total 50 150
The median class is 40 -60 as cf ≥ N/2
which is 33 ≥ 25
medain = 40 + |25-15|/18 ×20
medain = 40 + 200/18
median = 41.111
Mode = lower limit + f1-f0/2f1-f0-f2 × height
Here, f1 is the frequency of the modal class = 18.
f0 is the frequency of the preceding modal class = 9.
f2 is t/he frequency of the succeeding modal class = 13.
Mode = 40+ 18-9/2(18)-9-13
Mode = 52.857
Hence, the modal price is 52.857.

The standard deviation of the data is calculated as,
SD = √(∑f(x1)^2)/N - (mean)^2
SD = √149800/50- (50)^2
