Using the binomial distribution, it is found that the spinner is expected to have to spin approximately 132 times for a multiple of 5 to be spun 22 times, hence option 4 is correct.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected number of trials until q successes is:
[tex]E_f(X) = \frac{q}{p}[/tex]
In this problem:
We want 22 successes, hence q = 22.2 out of 12 sections(5 and 10) are multiples of 5, hence p = 1/6.Then:
[tex]E_f(X) = \frac{q}{p} = \frac{22}{\frac{1}{6}} = 22 \times 6 = 132[/tex]
Hence option 4 is correct.

Randy was paid $50 for his first night in the restaurant where he works as a cashier. he worked the rest of the week for $6.50 per hour. the equation, y = 6.50x + 50, represents the amount he made that week. What are the ordered pairs for the equation when you use these x-values: 10 and 20
Step-by-step explanation:
so, we first put 10 in for x :
y = 6.50×10 + 50 = 65 + 50 = $115
and then we put 20 in for x :
y = 6.50×20 + 50 = 130 + 50 = $180
so, the ordered pairs are
(10, 115) and (20, 180)
please help me solve the problem
Answer:
x = 130°
y = 50°
Step-by-step explanation:
x = 130° (Exterior alternate angles)
x + y = 180° (Angles in linear pair)
y = 180° - x
y = 180°- 130°
y = 50°
The solution to the problem in the figure attached in the question is: x = 130°, y = 50°
What are alternate angles?Alternate angles are angles that are formed in a situation whereby a line intersects two other lines, which lie on opposite sides of a transverse line and on contrasting proximate sides of the other lines.
From the given figure:
Angle x is an alternate angle to angle 130°.
Thus, x = 130°
Using the sum of angles on a straight line:
x + y = 180°
130° + y = 180°
y = 180° - 130°
y = 50°

The value of the given expression is -15 - 3y
What is the value of the expression?In maths, when there are terms in the bracket, it means we are to multiply the terms in the brackets by each other. This means that 5 + y would be multiplied by -3.
Multiplication is the process of determining the product of a set of numbers.

Answer:
y-intercept = (0, 8)
x-intercepts = (4, 0) and (-2, 0)
vertex = (1, 9)
5th point = (2, 8)
Step-by-step explanation:
As the coefficient of x² is negative, the curve will be "n" shaped.
y-intercept
crosses the y-axis when x = 0
substitute x = 0 into the function and solve for y:
[tex]\implies y=-(0)^2+(2 \times 0)+8=8[/tex]
Therefore, y-intercept = (0, 8)
x-intercept
crosses the x-axis when y = 0
set the function to zero and solve for x:
[tex]\implies -x^2+2x+8=0[/tex]
[tex]\implies x^2-2x-8=0[/tex]
[tex]\implies (x-4)(x+2)=0[/tex]
[tex]\implies x=4, x=-2[/tex]
Therefore, x-intercepts = (4, 0) and (-2, 0)
vertex
vertex form: [tex]y=a(x-h)^2 +k[/tex], where (h, k) is the vertex
expand vertex equation: [tex]y=ax^2 -2ahx+ah^2 +k[/tex]
compare coefficients with original function: [tex]y=-x^2+2x+8[/tex]
[tex]\implies a=-1, h=1, k=9[/tex]
So vertex = (1, 9)
5th plot point
You can choose any value of x and input it into the equation for y, but for symmetry, I have chosen to find the other value of x (aside x = 0) when y = 8
[tex]\implies -x^2+2x+8=8[/tex]
[tex]\implies -x^2+2x=0[/tex]
[tex]\implies x^2-2x=0[/tex]
[tex]\implies x(x-2)=0[/tex]
[tex]\implies x=0, x=2[/tex]
5th point = (2, 8)

The initial cost to rent a bike is $5. Each hour the bike is rented costs $1.75. is going to rent a bike and can spend at most $10.25. Write and solve an inequality to find how long she can rent the bike.
Answer:
1.75h + 5 ≤ 10.25
number of hours she can rent is a maximum of 3
Step-by-step explanation:
h = hours bike is rented

a bicycle shop is offering a 15% discount on a bike that has an original price of 275. there is an additional 5% discount off the sale price. what is the final price of the bike, including both discounts?
Step-by-step explanation:
• the original price= 275,
275 → 100 %
i) find the price with the 15 % discount
100% - 15% = 85 %
if, 275 → 100 %
100 % → 275
1% → 275 / 100
85 % → (275/100) * 85
= 233. 75
ii) find the add. 5% of the :
sale price = 233. 75
add. discount = 5%
= 5/ 100 * 233.75
= 11.6875
iii) subract the 5% discount from the sale price.
final price = 233. 75 - 11.6875
= 222. 0625

Maggie is buying 2 shirts that cost $8. 50 each. There is a 6. 5% sales tax. What is the total Maggie will pay for the shirts? Enter your answer in the box.
The total cost of the two shirt Maggie will pay after including the sales tax is $18.105.
What is cost price per ounce?The cost price per unit is the amount of money required to buy one unit of a brand or goods.
To find the cost price per unit, divide the total amount of cost of the goods to the total number of goods.
The cost of one shirt bought by the Maggie is $8. 50 each. Thus, the cost of the 2 shirts is,
[tex]C=2\times8.50\\C=17[/tex]
Thus, the total cost of the two shirts is $17.
Now, there is a 6. 5% sales tax on the selling price. Thus, the cost of the 2 shirts after the sales tax is,
[tex]C=17+17\dfrac{6.5}{100}\\C=17+1.105\\C=18.105[/tex]
Hence, the total cost of the two shirt Maggie will pay after including the sales tax is $18.105.

PLEASE HELP ME: the ratio of cars to trucks on a highway at any given time is 12 to 8. If there are always more than 105 cars on the highway, what is the minimum number of cars that can be on the highway?
Answer:
70
Step-by-step explanation:
First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.
Ps. I'm guessing you meant to ask the minimum number of trucks, not cars.
