. The wheel is divided into eight same-sized sections, and three of those sections represent winning a gift certificate. Assuming the wheel is fair, approximately how many gift certificates are likely to be won if 528 customers spin the wheel
Answers
The probability of winning is 3/8 since there are 3 winning spaces out of 8 total.
We expect to have (3/8)*528 = 198 winners
Note how if we had 198 winners out of 528 total players, then the empirical probability of winning is 198/528 = 3/8

Laisha noticed an increase in her customers over a period of five consecutive weeks. Based on
the pattern shown in the graph, make a conjecture about the number of customers Laisha will
have in the seventh week.
Laisha will have 7 customers
Laisha will have 8 customers.
Laisha will have 9 customers
Laisha will have 10 customers
Answers
Answer:
she will have 8
Step-by-step explanation: because it passes through the origin
In the 7th week, Laisha will have 8 customers. Option B is correct.
Given that,
Laisha noticed an increase in her customers over a period of five consecutive weeks. Based on the pattern shown in the graph, make a conjecture about the number of customers Laisha will have in the seventh week is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The slope of the function m = 1
y-intercept = 1
The equation that represents the condition,
y = x + 1
Where y = number of customers and x = number of weeks
Now for x = 7
y = 7 + 1
y = 8
Thus, in the 7th week, Laisha will have 8 customers. Option B is correct.

an additional $25 per week.
What is the minimum number of weeks that Brady will be able to purchase the skateboard? Justify
your answer.
Answers
Answer:
five almost 6 weeks
Step-by-step explanation:
brady is saving up to 245 but he already has 98 which means he needs to save 147 more dollars. Brady is making 25 a week so if you divide 147 by 25 you get 5.88 so in 6 weeks he can have a new skateboard with a couple extra doll hairs.

Is the equation 2x +
4 = 5x - 6 a literal equation? Explain.
Answers
Answer:
No
Step-by-step explanation:
Say for example that x = 1, so 2 + 4 = 5 - 6 that doesn't work and most likely wont work with any other number.
No, the equation [tex]2x + 4 = 5x - 6[/tex] is not a literal equation.
We have to given equation,
[tex]2x + 4 = 5x - 6[/tex]
What is literal equation?
A literal equation is an equation which consists primarily of letters.
Or we can say that, literal equation are equation with two or more variables.
Now, here given equation is [tex]2x + 4 = 5x - 6[/tex]
Clearly in the above equation only one variable use ( x ), so it is not literal equation.
Another way,
Put x = 1 in above equation we get,
2 + 4 = 5 - 6
clearly it is doesn't work.
So given equation [tex]2x + 4 = 5x - 6[/tex] is not a literal equation.

Solve algebraically for all the values of x -2x^5+14x^4-2x^3+14x^2=0
Answers
Answer:
0, 7, ± iStep-by-step explanation:
Solving for x
- 2x^5 + 14x^4 - 2x^3 + 14x^2=0x^5 - 7x^4 + x^3 - 7x^2 = 0x^2 ( x^3 - 7x^2 + x - 7) = 0x^2( x^2(x - 7) + (x - 7)) = 0x^2(x^2 + 1)(x - 7) = 0x^2 = 0 ⇒ x = 0x^2 + 1 = 0 ⇒ x^2 = -1 ⇒ x = ± ix - 7 = 0 ⇒ x = 7The solutions to the original equation -2x³ + 14x²- 2x³ + 14x² = 0 are x = 0, -0.391, 0.099, 7.293
To solve the equation algebraically, factor out an "x^2" term from each term:
x²(-2x³ + 14x²- 2x + 14) = 0
Now, we have two factors:
x² = 0
-2x³ + 14x² - 2x + 14 = 0
First, let's solve the first factor, which is a simple quadratic equation:
x² = 0
x = 0
Now, let's solve the second factor by factoring out a common factor of 2:
2(-x³ + 7x² - x + 7) = 0
Now,use the rational root theorem or synthetic division to find the roots of the cubic equation -x³ + 7x² - x + 7 = 0. However, in this case, the equation does not have any rational roots. Therefore, we need to use numerical methods or graphing techniques to find the approximate solutions.
Using numerical methods or graphing, we find that the approximate solutions for the equation -x³ + 7x² - x + 7 = 0 are:
x ≈ -0.391
x ≈ 0.099
x ≈ 7.293

One container of fertilizer covers 900 square feet. A property has a rectangular backyard that is 30 feet long and 20
feet wide. The front yard is triangular with a base of 24 feet and a height of 12 feet. What percentage of the container
will be used on the property? Round to the nearest percentage.
Answers
Answer:
82.67% of the fertilizer will be used on the property.
Step-by-step explanation:
Area of Plane Figures
The backyard described in the problem has two parts: One with a rectangular shape of 30 feet by 20 feet. The other with a triangular shape with a base of 24 feet and a height of 12 feet.
The area of a rectangle is calculated by:
[tex]A_r=L*W[/tex]
And the area of a triangle is:
[tex]\displaystyle A_t=\frac{B*H}{2}[/tex]
All the backyard will be covered by fertilizer coming from a container with a capacity of 900 square feet.
The total area of the backyard is the sum of the area of the rectangle Ar and the area of the triangle At as follows:
[tex]A_r=30*20=600\ ft^2[/tex]
[tex]\displaystyle A_t=\frac{24*12}{2}=144\ ft^2[/tex]
The total area of the backyard is:
[tex]A=600\ ft^2+144\ ft^2=744\ ft^2[/tex]
To find the percentage of the container, we calculate:
[tex]\displaystyle \frac{744}{900}*100\%=82.67\%[/tex]
82.67% of the fertilizer will be used on the property.
