Answer:
Jayla's expenses are: $245.00
Jayla's revenue from the sales are: $479.00
Total profit: $234.00
------------------------------------------
Hope this helps! This should be correct !
Answer:
- $245
+ $479
+ $234
Step-by-step explanation:
expenses : (25 x 2) + (15 x 3) + (30 x 5) = 50 + 45 + 150 = 95 + 150 = $245
revenue : (38 x 2) + (26 x 3) + (65 x 5) = 76 + 78 + 325 = 154 + 325 = $479
total profit : 479 - 245 = $234

During a clothing store's Bargain Days, the regular price for T-shirts is discounted by $6. There is a state sales tax of 5%, and the $6 discount is applied before the
sales tax is calculated. A). Write an expression that shows the regular price r of a T-shirt minus the $6 discount. B). Write a rule for the function p(r) that expresses the
final price p of a T-shirt with the discount applied and sales tax added. C). How much would you pay during Bargain Days for a shirt regularly priced at $20.00?
Answer:
A) The expression that shows the regular price minus the discount is r - 6
B) The function is p(r) = 1.05r - 6.3
C) You would pay $14.7 during Bargain Days
Step-by-step explanation:
∵ The regular price is r
∵ The discount on it is 6%
∴ The price after the discount = r - 6
A) The expression that shows the regular price minus the discount is
r - 6
∵ The state sales tax is 5% applied after the discount
∴ The sales tax = 5%(r - 6)
→ Change 5% to decimal y dividing it by 100
∵ 5% = [tex]\frac{5}{100}[/tex] = 0.05
∴ The sales tax = 0.05(r - 6) = 0.05(r) - 0.05(6)
∴ The sales tax = 0.05r - 0.3
∵ p is the price of the T-shirt with discount and sales tax
→ Add the sales tax to the regular price minus the discount
∴ p(r) = r - 6 + 0.05r - 0.3
→ Add the like terms
∴ p(r) = (r + 0.05r) + (-6 - 0.3)
∴ p(r) = 1.05r + (-6.3)
∴ p(r) = 1.05r - 6.3
B) The function is p(r) = 1.05r - 6.3
∵ The regular price of a shirt is $20
→ Substitute r by 20 in the function above to find how much you would
pay during the Bargain Days
∴ p(20) = 1.05(20) - 6.3
∴ p(20) = 21 - 6.3
∴ p(20) = $14.7
C) You would pay $14.7 during Bargain Days
Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem, Later, respond to your own post with your own solution. For example, you may believe that the population mean number of times that adults go out for dinner each week is less than 1.5. Your data could be that you spoke with 7 people and found that they went out 2, 0, 1, 5, 0, 2, and 3 times last week. You then would choose to test this hypothesis at the .05 (or another) significance level. Assume a random sample.
Required:
Test this hypothesis at the 0.05 significance level.
Answer:
There is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5
Step-by-step explanation:
From the question we are told that
The population mean is less than 1.5
The sample size is n = 7
The sample data is 2, 0, 1, 5, 0, 2, and 3
Generally the sample mean is mathematically represented as
[tex]\= x = \frac{ \sum x_i }{ n }[/tex]
=> [tex]\= x = \frac{ 2 + 0 + 1 + 5 + 0 + 2 + 3 }{ 7 }[/tex]
=> [tex]\= x = 1.857 [/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{\frac{\sum (x_i - \= x)^2}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{ (2 - 1.857)^2 + (0 - 1.857)^2 +\cdots (3 - 1.857)^2}{7} }[/tex]
=> [tex]\sigma = 1.773[/tex]
The null hypothesis is [tex]H_o : \mu = 1.5[/tex]
The alternative hypothesis is [tex]H_a : \mu < 1.5[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{\= x - \mu }{ \frac{\sigma }{\sqrt{n} } }[/tex]
=> [tex]z = \frac{\= x - 1.857 }{ \frac{1.773 }{\sqrt{7} } }[/tex]
=>[tex]z = 0.53[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = P(z < 0.53 )[/tex]
From the z-table
[tex]P(z < 0.53 ) = 0.70194[/tex]
So
[tex]p-value = 0.70194[/tex]
From the values obtained we see that [tex]p-value > 0.05[/tex]
Here there is no sufficient evidence to conclude that population mean number of times that adults go out for dinner each week is less than 1.5
Theo is driving with his mom to Paso Robles. It took Theo 4 hours to drive 228 miles. Lex drove with his dad to San Luis Obispo. Lex drove 186 miles in 3 hours. a. How far does Theo drive in 1 hour? How far does Lex drive in 1 hour? b. Who drove faster? Explain how you know.
Answer:
A. Theo drove 57 miles and Lex drove 62 miles in 1 hour.
B. Lex drove faster. We know this because in order to figure out how many miles each drove per hour you need to find there individual rate. Which is 228/4 and 186/3. You want to divide using the hours so you generate a response where 1 hour is the only thing left. Thus giving you mph (miles per hour). Lex is drove 5 miles more in an hour than Theo leading us back to who drove faster. Lex did.

Cary hiked 18 miles in 6 hours. If he continues at the same pace, how much farther can he hike in the next 2 hours?
Answer: I believe the answer is 6 miles.
Step-by-step explanation: Its states Cary hiked 18 miles in 6 hours. If you divide 18 by 6, you get the answer 3. This means that 6 multiplied by 3 will give you 18, so just do the same to the number 2. Two multiplied by 3 gives you 6.
let their number of sides of a regular polygon is 6 in its radius is 5,then find the length of the side.
Step-by-step explanation:

Your teacher asks the class to evaluate the expression (3³)¹. Your classmate gives an incorrect answer of 81. Evaluate the expression. Then find the likely error. **PLEASE FIND THE ERROR I DON'T NEED THE ANSWER I KNOW ITS 27**
Answer:
see explanation
Step-by-step explanation:
The most likely error is adding the exponents instead of multiplying them, that is
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex] , then [tex](3^{3}) ^{1}[/tex] = [tex]3^{3(1)}[/tex] = 3³ = 27
However
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] ← the student may have used this definition to obtain 81

A sheet of notebook paper is four thousandths of an inch thick. What is the thickness, in centimeters, of a 500-sheet stack of notebook paper
Answer:
2 inches thick
Step-by-step explanation:
4/1000*500
Thickness of a 500 sheet stack of notebook paper is 5 cm.
What is Measurement units?
A measurement unit is a standard quality used to express a physical quantity.
Given that;
Thickness of a sheet of notebook paper = 0.004 inch
Now,
1 inch = 2.54 cm
Hence, Thickness of a sheet of notebook paper = 0.004 inch
= 0.004 × 2.54 cm
= 0.01016 cm
= 0.01 cm
So, Thickness of a 500 sheet stack of notebook paper = 500 × 0.01
= 5 cm
Thus, Thickness of a 500-sheet stack of notebook paper is 5 cm.

please help me A portion of Taquan's check register is shown. Before Taquan made his utility payment on March 24, the balance of his account was $1,094.80.
The check register is used to show the total amount Taquan spent
Using the assumed values, Taquan's initial balance is $1336.26
How to determine the amount before making the utility payment?The question is incomplete, as the check register is not shown.
So, I will give a general explanation
Assume that the utility bill is $241.46
From the question, the new balance on March 24 is $1094.80
This means that the initial balance is:
Initial balance = New balance + Utility bill
This gives
Initial balance = $1094.80 + $241.46
Evaluate the sum
Initial balance = $1336.26
Using the assumed values, Taquan's initial balance is $1336.26

Step-by-step explanation:
Volume of a Cone
The volume of a right circular cone with height h and a base radius r is:
[tex]\displaystyle V=\frac{1}{3}\pi r^2 h[/tex]
The height of the given cone is h=4.1 cm and its diameter is d=14.8 cm. Since the radius is half the diameter, r=7.4 cm.
Calculate the volume:
