Answer:
$38.30
Step-by-step explanation:
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Sum of the numbers = $20 + $45 + $30.50 + $46 + $50 = $191.50
Total number = 5
Mean = $191.50 / 5 = $38.30
What is the value of x in the equation shown below?
x3 + 1 = 9
Answer:
x = 7/3 or 2.33
Step-by-step explanation:
x3 + 1 = 8
x3 = 8 - 1
x3 = 7
x = 7/3 or 2.33
HOPE THIS HELPS YOU!! :)
Answer: x = 2
Step 1.
In order to solve this non-linear equation, we need to move all the terms to the left side.
In x³ + 1 = 9...
- term 1, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
Rewrite the equation like this: (x³ + 1) + (-1) = 9 + (-1)
Step 2.
Add x³ + 1 + (-1)
x³ + 1 + (-1) = 8
Now, x = 8.
Step 3.
In this non-linear equation, the variable needs to be isolated.
This is accomplished when both sides are exponentiated by the reciprocal of the variable's exponent, which in our example, 1/3 is equal to
Notice that since we exponentiated a simplified fraction with an odd denominator, only one solution has been created.
Rewrite the equation: [tex](x^3)^\frac{1}{3} =8^\frac{1}{3}[/tex]
Step 4.
We need to exponentiate the power.
The following rule is applied: [tex](A^B)^C=A^B^C[/tex]
According to the formula,
A = X
B = 3
C = 1/3
Rewrite the equation: [tex]x^3^\times^\frac{1}{3} =(2^3)^\frac{1}{3}[/tex]
Step 5.
We need to reduce this fraction, the 3 in x to the lowest terms.
This can be done by dividing out those factors that appear both in the numerator and in the denominator.
In our example, 3 is the common factor.
Rewrite the equation: [tex]x=2^\frac{3}{3}[/tex]
Step 6.
Lastly, we'll need to do the same thing as we did in step 5. Reduce the fraction in [tex]x=2\frac{3}{3}[/tex]. This can be done by dividing out those factors that appear both in the numerator and in the denominator.
Hence, the common factor is 3 since it occurs both in the numerator and the denominator.
Hence, x = 2.

Anthony makes candies for his party guests. First, he mixes 1 cup of cream with 2 cups of chocolate. In all, he uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?
Answer:
Cream = 3 cups
Chocolate = 6 cups
Step-by-step explanation:
Cream = 1 cup
Chocolate = 2 cups
Total = 3 cups
Cream : chocolate = 1 : 2
He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?
Cream = ratio of cream/total ratio of total cups
= 1/3 of 9
= 1/3 × 9
= 3 cups
Cream = 3 cups
Chocolate = ratio of chocolate/total ratio of total cups
= 2/3 of 9
= 2/3 × 9
= 6 cups
Chocolate = 6 cups
Which of the following ratios is equivalent to the ratio 3:4?

5. The graph of a function is a line that
passes through the coordinates (2, 11)
and (8, 14).
Write an equation in the form
y = mx + b for this function.
Answer:
y = 1/2x + 10
Step-by-step explanation:
(y-11)/(14-11) = (x-2)/(8-2)
(y-11)/3 = (x-2)/6
2y-22 = x-2
2y = x + 20
y = 1/2x + 10
Let m = slope of the line.
m = (14 - 11)/(8 - 2)
m = 3/6
m = 1/2
We now have the slope and the slope is 1/2.
We plug the slope and one of the point into the point-slope formula.
Here is the point-slope formula:
y - y_1 = m(x - x/_1)
I will use the point (2, 11).
y - 11 = (1/2)(x - 2)
y - 11 = (1/2)x - 1
Now we solve for y by adding 11 to both sides of the equation.
y = (1/2)x - 1 + 11
Answer: y = (1/2)x + 10

6x+7+x^2+2x^2-3
3x^2+6x+7-3
3x^2+6x+4
The sum of the polynomials is 3x² + 6x + 4.
What are Polynomials?Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given are two polynomials whose sum has to be found.
(6x + 7 + x ²) and (2x² - 3).
The sum of the polynomials is,
(6x + 7 + x ²) + (2x² - 3)
We have to operate the like terms together.
= (6x) + (7 - 3) + (x² + 2x²)
= 6x + 4 + 3x²
= 3x² + 6x + 4
Hence the sum of the polynomials is 3x² + 6x + 4.

The inequality that represents the number of adults and children who can go to a show using the $30 gift certificate is:
x < 4 and y < 7.
Where x is the number of children and y is the number of adults.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Makenzie got a $30 gift certificate to the local theater for her birthday. Adult tickets (x) cost = $8.00
Children's tickets (y) cost = $4.50
Now,

4.50y = 30
y = 30/4.50
y = 6.67

The graphs below were created by an advertising agency for the computer store TechPlus to show its average price on laptops and desktops compared to another computer store's prices.
Which of the following statements best explains how the advertising agency misrepresented the data?
The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.
The graphs were created with different colors.
The graph for CompStar makes its prices appear much higher, but its prices are only a little higher.
The graphs do not include tablet computers, so there is not enough information to compare their prices.
The misrepresentation lies in the fact that ; The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.
Taking a look at both graphs, it could be observed on the y - axis that the graphs do not follow the same scale.
For CompStar, the y-axis which shows the price of laptops and desktops starts it's labeling from $0 ; while TechPlus's labeling began from $600
This representation means that comparing the two graphs would give an erroneous inference as it would make the price of TechPlus appear lower than that of Complus.

Jane made a door frame for the house but does not have a tool to measure the angles. How can she check that the corner is 90 degrees?
Answer:
She can use any square object around her. Since squares are made up of right angles, any side she chooses can be used to compare the angle of the door. If the square corner fits perfectly, the angle is 90. If the square fits with space, obtuse. If the square doesn’t fit, acute

Answer: 79%
Step-by-step explanation:
Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:
= 90% × 3
= 270%
Since he scores 46% on his next quiz, we add it to the previous score and this will be:
= 270 + 46
= 316
Then, his mean quiz score for these 4 quizzes will be:
= Total score / Number of quizzes
= 316 / 4

The average person's stride lenghth the distance covered by one step is aproximently 2.5 feet long. How many steps would the average person take to travel 50 feet?
Answer: 20 steps
Step-by-step explanation:
From the question, we are informed that the average person's stride length the distance covered by one step is 2.5 feet long.
To know the steps that the average person would take to travel 50 feet, we simply have to divide 50 feet by 2.5 feet. This will be:
= 50 / 2.5
= 20
This means that an individual will take 20 steps to travel 50 feet
