A chain of stores knows that 90\%90%90, percent of its customers pay with a credit or debit card, 5\%5%5, percent pay with cash, and 5\%5%5, percent pay with a service on their smartphones. They installed a new system for receiving payments, and they wonder if these percentages still hold true. They plan to take a random sample of customers in order to perform a \chi^2χ
2
\chi, squared goodness-of-fit test on the results.
What is the smallest sample size the company can take to pass the large counts condition?
100 people cuz 90% of 100 is 90
5 % is 5
So its easier to interpret
Answer:
The smallest sample size the company can take and still pass the large counts condition is 100 total customers.
Step-by-step explanation:
The large counts condition says that all expected counts need to be at least 5. The company needs to sample enough customers so that they expect each mode of payment to appear at least 5 times. Since the distribution they expects is uneven, we should look at the mode of payment that has the lowest expected percentage.
The lowest expected percentage is 5%, percent, which is the percentage of both cash and payment via smartphone, We need to pick a sample so 5%, percent of its size equals at least 5.
0.05x ≥5
x ≥100
So, the company needs to sample at least 100 customers.
Gia receives an allowance of $2 a week and already has $20 in savings. Michael receives an allowance of $3 a week and already has $5 in savings. Gia and Michael both save their entire allowance. After how many weeks, will Gia and Michael have the same amount in savings? How much money will they have?
Answer:
After 15 weeks, Gia and Micheal will both have $50 in savings.
Step-by-step explanation:
For Gia:
We start at $20 since she already has $20 in savings, we will add that to how much Gia will receive in 15 weeks.
Gia receives $2 a week and therefore in 15 weeks she will have $50.
= 2x15 = $30
= 30+20 = $50
For Micheal:
We start at $5 since he already has $5 in savings, we will add that to how much Micheal will receive in 15 weeks.
Micheal receives $3 a week and therefore in 15 weeks he will receive $50
= 3x15 = $45
= 5+45 = $50
Question 2: Sarah is fencing a vegetable garden to keep rabbits out. The hardware store sells

Step-by-step explanation:
1. $165/$25.50=6.47058823529m
2. she should use a circle because they have the greatest area, the circle should have a circumference of 6.47m.
please help mee!! will mark brainliest! "the Kuna Caveman football team won 75% of their games. If they won 9 games, how many games did they play?"
Answer:
12 games
Step-by-step explanation:
Let x be the number of games played
The y won 75% of the games played and that was 9
x * 75% = 9
Change to decimal form
x * .75 = 9
Divide each side by .75
x * .75 /.75 = 9/.75
x =12
They played 12 games

USE SYSTEMS BY SUBSTITUTION.
X=
Y=
Answer:
X=-2
Y=0
Step-by-step explanation:
X+y=-2 = x=-2-y
3x+4y=-6
3(-2-y)+4y=-6
-6-3y+4y=-6
y=0
x+3(0)=-2
x=-2
Answer:
[tex]\boxed {\boxed {\sf (-2,0)}}[/tex]
Step-by-step explanation:
To solve by substitution we must first isolate 1 variable in an equation.
Let's use the first equation.
[tex]x+3y= -2[/tex]
Subtract 3y from both sides to isolate the variable x.
[tex]x+3y-3y= -2 -3y[/tex]
[tex]x= -2 -3y[/tex]
Now we can substitute the expression (-2-3y) in for x in the second equation.
[tex]3x+4y= -6[/tex]
[tex]3(-2-3y)+4y= -6[/tex]
Distribute the 3. Multiply each term inside the parentheses by 3.
[tex](3*-2)+ (3*-3y)+4y=-6\\-6-9y+4y=-6[/tex]
Combine the like terms on the left side.
[tex]-6-5y= -6[/tex]
Add 6 to both sides to isolate the variable.
[tex]-6+6-5y=-6+6\\-5y=0[/tex]
Divide both sides by -5.
[tex]-5y/-5=0/-5 \\y=0[/tex]
Now we know that y is equal to 0 and can substitute it into the first equation and find x.
[tex]x+3(0)=-2[/tex]
[tex]x+0=-2 \\x= -2[/tex]
x is equal to -2 and y is equal to 0.

You sell instruments at a Caribbean music festival. You earn $326 by selling 12 sets of maracas, 6 sets of claves, and x djembe drums. Find the number of djembe drums you sold
First, it is important to know the prices of each of the instruments in order to determine the number of djembe drums you had sold. Since it is not given here. I will give a general equation where you just substitute the prices. It would be as follows:
326 = 12x + 6(y) + (xx)z
where x is the price for a set of maracas
y is the price for a set of claves
xx is number of djembe drums sold
z is the prices for each djembe drum
Hope this helps. Have a nice da
Answer:
(14*12)+(5*6)+16x
Step-by-step explanation:
First, you get the price of every instrument.
(Shown in the picture)
Maracas: $14
Claves: $5
Djembe Drums: $16
Then multiply the price to how many instruments you sold.
14*12 (Maracas)
5*6 (Claves)
You don't know what how many djembe drums you sold, so put an x right next to 16.
To get the total of $326 in that equation, you do: (14*12)+(5*6)+16x.
I hope it helps.

Dividend is equal to :
divisor * quotient - remainder
divisor , quotient
divisor x quotient + remainder
divisor * quotient x remainder
Answer:
divisor × quotient + remainder
Step-by-step explanation:
the dividend is the number thats going to be divided. (for example, 10 crayons divided by 2 people). the formula to find this would be multiplying the divisor by the quotient, and adding the remainder if there is one.
Dividend is equal to:
divisor × quotient - remainderdivisor , quotientdivisor x quotient + remainderdivisor × quotient x remainder✭ Explanation -:To solve this question first we should know the following terms :
[tex] \bull \: \small\sf{ Dividend}[/tex]
A number to be divided by another number.[tex] \bull \: \small\sf{ Divisor}[/tex]
A number by which another number is to be divided.[tex] \bull \: \small\sf{ Quotient}[/tex]
A result obtained by dividing one number by another.The formula for dividend is
[tex] \star \: \small \boxed{\sf{ Dividend = Divisor × Quotient + Remainder }}[/tex]
Hence opition 3) is the correct answer.Hospital waiting room times are normally distributed with a mean of 38.12 minutes and a standard deviation of 8.63 minutes. What is the shortest wait time that would still be in the worst 5% of wait times? Homework Help: 4VE. Determining values from normal distributions based on probabilities (Links to an external site.) (2:42) 4DC. Using normal distributions and probabilities to determine set values DOCX Group of answer choices 29.49 minutes 52.32 minutes 23.92 minutes 46.75 minutes
Answer:
Step-by-step explanation:
waiting times follow a normal distribution with
Mean, \mu=38.12Mean,μ=38.12
Standard\ deviation,\sigma=8.63Standard deviation,σ=8.63
Longer waiting times are worse than shorter waiting times. Hence the worst 20% of wait times are wait times on the right tail of the distribution. The inferred level of confidence is 0.80.
The z value corresponding to the right tail probability of 0.2 is
Z=0.85Z=0.85
But
Z = \frac{x-\mu}{\sigma}Z=
σ
x−μ
x =Z*\sigma +\mux=Z∗σ+μ
=0.85 * 8.63 +38.12 =45.4555=0.85∗8.63+38.12=45.4555
answer:
the shortest wait time that would still be in the worst 20% of wait times is 45.4555 minutes
