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.

The percentage error of 35/6 is 3x10⁻³
What does the percentage of mistake mean?Percent error calculates the difference between an estimate and a right number and expresses it as a percentage. Analysts can use this statistic to determine how big the mistake is in relation to the actual number. It is also referred to as % error and percentage error.

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.
4. y = -4x + 3.
5. y = 4x + 1.

Guadalupe is going to a carnival that has games and rides. Each game costs $2.50 and each ride costs $3.75. Guadalupe spent $36.25 altogether on 12 games and rides. Write a system of equations that could be used to determine the number of games Guadalupe played and the number of rides Guadalupe went on. Define the variables that you use to write the system.
System of equations required to determine number of games and rides are x + y=12, 2.50x + 3.75y=36.25 where x represents number of games and y number of rides.
As given,
Let x represents the number of games
and y represents the number of rides
System of equation are:
x+ y=12 ___(1)
2.50x+3.75y=36.25 ___(2)
Multiply 2.50 to (1) subtract from (2) we get,
1.25y=6.25
⇒y=5
Hence, x=12-5
=7

a) mean price

c)modal price
d)standard deviation
The correct answer is The mean price is 50.
The median price is 41.111.
The modal price is 52.857.
The standard deviation price is 22.271.
The data table represents the prices (in R) of 50 items purchased by a shopper is,
Price Frequency
0<20 6
20<40 0
40<60 18
60<80 13
80<100 4
Explanation:
The mean of the data is the average of the given values.
The mean of the data is calculated as,
Price frequency (f) Mid point (xi) f.xi
0-20 6 10 60
20-40 9 30 270
40-60 18 50 900
60-80 13 70 910
80-100 4 90 360
Total 50 250 2500
Mean = ∑fx1/N
Mean = 2500/50
Mean = 50
Price frequency (f) cf
0-20 6 6
20-40 9 15
40-60 18 33
60-80 13 46
80-100 4 50
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.
Price frequency (f) Mid point (xi) f.(xi)^2
0-20 6 10 600
20-40 9 30 8100

60-80 13 70 63700
80-100 4 90 32400
Total 50 149800
The standard deviation of the data is calculated as,
SD = √(∑f(x1)^2)/N - (mean)^2
SD = √149800/50- (50)^2
SD = 22.271
Hence, the standard deviation of the data is 22.271.

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) )

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

The height of the window is 9-x feet, the perimeter of the window is 36-2x.
What is an expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression.
What is algebraic expression?Using letters or alphabets to represent numbers without giving their exact quantities is the idea behind algebraic expressions. The principles of algebra taught us how to express an unknown value using letters like x, y, and z. Here, we refer to these letters as variables.
Given that,
A window is 9 feet long.
Its length exceeds its height by x feet.
The length of the window = 9 feet
Then, the height of the window,
x feet shorter than the length= 9-x feet
As a result, the window is 9-x feet tall.
The perimeter of the window is 2 (l+b)

A mixed fraction is a fraction that is represented with its quotient and remainder. For example there is a mixed fraction [tex]5\frac{2}{3}[/tex] where 5 is the quotient and 2 is the remainder. To convert a mixed fraction to a simple fraction we multiply the denominator by the quotient and add the remainder to it to get the numerator of the simple fraction, the denominator remains the same. In this question we have to find the cups of ingredients that Natasha uses to make the sauce, we have to simplify all the mixed fractions and then add the fraction together to get the number of cups.
cups of cream=[tex]2\frac{3}{4}[/tex]=11/4
teaspoon of salt =1/2
cups of chive=3/8
cups pf butter=[tex]1\frac{1}{4}[/tex]=5/4
total cups of ingredients used= 11/4+3/8+5/4=(22+3+10)/8=35/8≈4 cups
