A local eat-in pizzeria wants to investigate the possibility of starting to deliver pizzas. The owner of the store has determined that home delivery will be successful only if the average time spent on a delivery does not exceed 37 minutes. The owner has randomly selected 15 customers and delivered pizzas to their homes. What hypotheses should the owner test to see whether that the pizza delivery will be successful
Answer:
Hypothesis Test is:
Null Hypothesis H₀ x = 37
Alternative Hypothesis Hₐ x > 37
With that test hypothesis if we accept H₀ the result indicates that we can support that the average delivery time is equal to 37 we can proceed with the project. If on the other hand, we need to reject H₀ that means that the average delivery time exceed 37
Step-by-step explanation:
The limit average time is 37 minutes. Therefore under that value, the owner is happy. From the sample we have:
Sample size n = 15
we have data from delivery times then we have the mean x of the sample and standard deviation of the sample s
We assume normal distribution and as n < 30 test should be developed with t - student distribution.
Hypothesis Test is:
Null Hypothesis H₀ x = 37
Alternative Hypothesis Hₐ x > 37
With that test hypothesis if we accept H₀ the result indicates that we can support that the average delivery time is equal to 37 we can proceed with the project. If on the other hand, we need to reject H₀ that means that the average delivery time exceed 37

Step-by-step explanation:
Put the given numbers in the formula and do the arithmetic.
P = $300, r = 0.13, n = 1, t = 7
__
A = $300.00(1 + 0.13/1)^(1·7)
A = $300·(1.13^7) ≈ $300·2.35260548
A = $705.78
There will be $705.78 in the account after 7 years.

A system consists of two independent components in parallel. The system works if at least one of the components works. If each component works with probability 0.65, what is the probability that the system works
Answer:
The probability that the system works is 87.75%.
Step-by-step explanation:
Given that a system consists of two independent components in parallel, and the system works if at least one of the components works, if each component works with probability 0.65, to determine what is the probability that the system works the following calculation must be performed:
1 - 0.65 = 0.35
0.35 x 0.35 = X
0.1225 = X
1 - 0.1225 = 0.8775
Therefore, the probability that the system works is 87.75%.

Solve for the value of z
Answer:
z=26
Step-by-step explanation:
4z-8+3z+6=180
7z-2=180
7z=182
z=26
Answer:
z=26
Step-by-step explanation:
add the 2 equation together to equal 180
4z-8+3z+6
combine like terms
7z-2=180
add 2 to both sides
7z=182
divide by 7 to isolate z
z=26
24. Identify the center and radius of the circle given the equation (x +15)2 + (7 - 9)2 = 25 .
a. Center: (-15, 9), Radius: 5
b. Center: (15, -9), Radius: 25
c. Center: (-15, -9) Radius: 5
d. Center: (15,9) Radius: 25
Answer:
a. Center: (-15, 9), Radius: 5
Step-by-step explanation:
Equation of a circle:
The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In this question, we have that:
[tex](x + 15)^2 + (y - 9)^2 = 25[/tex]
Comparing both equations:
[tex]x - x_0 = x + 15[/tex]
[tex]x_0 = -15[/tex]
And
[tex]y - y_0 = y - 9[/tex]
[tex]y_0 = 9[/tex]
The center is [tex](-15,9)[/tex].
For the radius:
[tex]r^2 = 25[/tex]
[tex]r = \sqrt{25} = 5[/tex]
The correct answer is given by option a.
Represent the following sentence as an algebraic expression, where "a number" is the
letter x. You do not need to simplify.
Twice the difference of 1 and a number.
Answer:
2(1 - x)
Step-by-step explanation:
Twice the difference of 1 and a number
a number = x
The difference of 1 and a number is expressed as :
1 - x
Twice this difference, means the difference of (1-x) multiplied by 2
2 * (1 - x) = 2(1 - x)
if 2(a-3)=3(a+2) then a =6
Answer:
No, a=-12
Step-by-step explanation:
To solve this, you have to use the distributive property. 2(a-3) is going to be equal to 2a-6 and 3(a+2) is going to be equal to 3a+6. This will make the equation 2a-6=3a+6. You add 6 from both sides to isolate a. This will make the equation 2a=3a+12. Subtract 3a from both sides to get -a=12. You want to isolate a so you have to divide both sides by -1. This will make the equation a=-12.

Find the sum.
10 + 12 + 14 + ... + 80
Answer:
1620
Step-by-step explanation:
The amount of even integers between 10 and 80 inclusive is 36 (5 for each interval of 10 [e.g., 10-19 has 5, 20-29 has 5] and one extra for 80).
Since the numbers are consecutive even numbers, we can use the fact that the sum of the numbers is equal to the average of the numbers, times the number of numbers.
The average of the numbers is 45, since [tex]\frac{10+80}{2}=45[/tex]. We can use only the two outer numbers to determine the average since the numbers are all evenly spaced as they are consecutive even numbers.
[tex]45\times36=1620[/tex], so the sum is 1620.

What is the value of the expression of x=5 6x^3 +8x
Answer:
790
Step-by-step explanation:
Substitute the value (x = 5) into the following expression, replace the parameter (x) with the value (5) wherever the parameter (x) is present,
[tex]6x^3+8x[/tex]
[tex]6(5)^3+8(5)[/tex]
Simplify use the order of operations. The order to operations is the system of steps that one uses to solve an equation, these steps are the following,
1. Parenthesis
2. Exponents or Radicals
3. Multiplication or Division
4. Addition or subtraction
Quick note, a number to any exponent is equal to the number times itself the number of times the exponent indicates.
Use these steps to simplify the given expression,
[tex]6(5)^3+8(5)\\\\=6(125)+8(5)\\\\=750+40\\\\=790[/tex]

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67.
So, the Marked up amount
= 160 % of 82.67
= $132. 272
and, then 10% discount
= 10% of 132.272
= 13.2272
so, the discount price = 82.67 - 13.2272 = $69.4428

Answer:
A)15x+30=weekly income
B)8 hours
Step-by-step explanation:
15x+30= weekly income
The 15 multiplies because it says per hour
The 30 is constant because she only earns it once (per week)
15x+30=150
minus 30 from both sides
15x=120
