Ken is building an outdoor walking path with pavers. Pavers are sold 10 for $8 or $1 per paver. Ken needs 52 pavers to complete the walking path what is the least amount that 52 pavers cost?
Ken is building an outdoor walking path
Pavers are sold 10 for $8 or $1 per paver
Ken needs 52 pavers to complete the walking path
if 10 pavers is sold for $8
52 / 10 = 5 remainder 2
This means he is going to buy 50 pavers for
5 x $8 = $40
Remaining two pavers
Since, 1 paver is sold for $1
The 2 pavers will be sold for $2
$40 + $2 = $42
The least amount that 52 pavers will cost is $42

Probability of a seal living less than 7.4 years, P(X < 7.4) = 0.023
Explanations:The distribution is said to be a normal distributuion.
For a normal distribution, you first calculate the z value.
[tex]\begin{gathered} \text{Average life, }\mu\text{ = 13.8} \\ \text{Standard Deviation, }\sigma\text{ = 3.2} \\ \text{The observed value, x = 7.4} \end{gathered}[/tex]The z value is calculated as:
[tex]\begin{gathered} \text{z = }\frac{\text{x -}\mu}{\sigma} \\ z\text{ = }\frac{7.4-13.8}{3.2} \\ z\text{ = }\frac{-6.4}{3.2} \\ z\text{ = -2} \end{gathered}[/tex]The probability of a seal living less than 7.4 years can be represented mathematically as:
P ( X < 7.4) Which can be interpreted as P(z < -2)
Checking this is in standard normal table:
P( z < -2) = 0.02275
Approximating to 3 decimal places, P(z < -2) = 0.023
Therefore, P ( X < 7.4) = 0.023

the cost for an adult admission is 22 $
cost for child is 22 - 5 = 17 $
total cost for 12 adults is 12 x 22 = 264
total cost for 15 children is 15 x 17 = 255
so the total cost of admission for 12 adults and 15 children is,
= 264 + 255
= 519 $
so the answer is 519 $
The initial balance of a savings account was $676. After which transactions will the balance of the savings account be the same as the initial balance? A. A withdrawal of $45, followed by a withdrawal of $45 Vocabulary Box: B. A deposit of $36, followed by a withdrawal of $36 Initial balance: starting amount ($$) C. A withdrawal of $67, followed by a deposit of $45 Transactions: deposits or withdrawals D. A deposit of $168, followed by a deposit of $168 Deposit: Put money in (+) please help
ANSWER
B
EXPLANATION
The intial balance of the savings account was $676.
Let us check the options A to D to see which of them is going to leave the same amount as the initial amount.
A. A withdrawal of $5 followed by a withdrawal of $45.
A withdrawal means money was taken so, the final balance will be:
$(676 - 45 - 45)
= $586
The final is not the same as the initial.
B. A deposit of $36, followed by a withdrawal of $36.
A deposit means money was added to the account, so the final balance is:
$(676 + 36 - 36)
= $676
The final amount is the same as the initial.
C. A withdrawal of $67, followed by a deposit of $45.
So, the final balance will be:
$(676 - 67 + 45)
= $654
The final amount is not the same as the initial.
D. A deposit of $168, followed by a deposit of $168.
So, the final balance will be:
$(676 + 168 + 168)
= $340
The final amount is not the same as the initial.
So, the correct choice is B because the final amount is the same as the initial amount

CR. 4: Two spinners-One 5 and one 6. What is the probability that you will spin thesame number on both spinners twice. What is the probability that you get two numbersthat have the SUM of 5? What is the probability that you land on an even number?Lastly, what is the probability that you will get one 2 and one 3 when you spin?(OR NewSpinners)
We will denote the first spinner as S5 and the second one as S6.
1) Probability spin the same number is both spinners twice
The probability of landing in a given number using S5 is equal to 1/5, while when using the S6 the probability is 1/6.
First, we get the same result twice using S5, this probability is given by:
[tex]P(S5_{\text{twice}})=\frac{1}{5}\cdot\frac{1}{5}=\frac{1}{25}[/tex](An specific number, of the 5 available, twice) Notice that the result we obtain with S5 does not affect what we obtain with S6.
On the other hand, the probability of getting any number twice in a row, using S6, is:
[tex]P(S6_{\text{twice}})=\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36}[/tex](An specific number, of the 6 available, twice) In case the problem refers to the probability of spinning S5 once, then S6, and obtaining the same number:
First, notice that there are a total of 5 results that satisfy this condition
(1,1),(2,2),(3,3),(4,4),(5,5)
And there is a total of 5*6=30 possible combinations. 30 different pairs (S5,S6).
So, the probability is the number of positive cases divided by the total amount of cases:
[tex]P(S5=S6)=\frac{5}{30}=\frac{1}{6}[/tex]This is the probability of getting the same number if you spin S5 and S6 once each.
2) Probability getting two numbers which SUM is equal to 5
Let's suppose that the problem refers to spinning once each one of the spinners and then adding the results.
First, we need to get the pairs that add up to 5
(S5,S6)
(1,4),(4,1)(2,3),(3,2). These are the only pairs that satisfy the condition.
And remember that, when spinning S5 and S6 once each, there are 30 possible combinations. So, the probability we are looking for in part 2 is:
[tex]P(SUM(5))=\frac{4}{30}=\frac{2}{15}\approx0.1333\ldots[/tex]3) Landing on an even number
In the case of S5, there are 2 even numbers:2,4 and 5 numbers on which the spinner can land:1,2,3,4,5.
So, the probability is:
[tex]P(S5_{\text{even}})=\frac{2}{5}=0.4[/tex]On the other hand, the probability of getting an even number with S6 is:
[tex]P(S6_{\text{even}})=\frac{3}{6}=0.5[/tex]We can even find the probability of spinning S5 once, then S6, and get an even number. Since the events are independent, that probability is:
[tex]P(S5_{\text{even}})\cdot P(S6_{\text{even}})=0.4\cdot0.5=0.2=\frac{1}{5}[/tex]d) Get one 2 and one 3.
Once again, there is a total of 2 pairs that satisfy this condition: (2,3) and (3,2), and there is a total of 30 combinations when we spin S5 and S6. So,
[tex]P(2and3)=\frac{2}{30}=\frac{1}{15}\approx0.0666[/tex]And that's the answer to the fourth question

A company needs to create a concrete foundation 3 feet deep measuring 56‘ x 26‘, outside dimensions, with walls 5 inch thick how many cubic yards of concrete will they need?
We are asked to determine the volume of the concrete wall with the given dimensions. To do that we will determine the volume of the exterior prism with dimensions 56ft, 26ft, and 3ft. This volume is given by the product of its dimensions:
[tex]V_e=(56ft)(26ft)(3ft)[/tex]Solving the operations we get:
[tex]V_e=4368ft^3[/tex]Now, we need to determine the interior volume. That is the prism that is inside the foundation. To determine the dimensions we need to convert 5 inches to feet. To do that we will use the following conversion factor:
[tex]1ft=12in[/tex]Multiplying by the conversion factor we get:
[tex]5in\times\frac{1ft}{12in}=0.42ft[/tex]Now we determine the length and width of the inside prism. To do that we use the following:
Therefore, we need to subtract 2 times 5 inches to each of the exterior dimensions to get the inner dimensions, therefore, the interior volume is:
[tex]V_i=(56ft-2(5in))(26ft-2(5in))(3ft)[/tex]Substituting the inches we get:
[tex]V_i=(56ft-0.83ft)(26ft-0.83ft)(3ft)[/tex]Solving the operations:
[tex]V_i=4165.89ft^3[/tex]Now, the volume of the wall is the difference between the exterior volume and the interior volume. Therefore:
[tex]V=V_e-V_i[/tex]Substituting the values we get:
[tex]\begin{gathered} V=4368ft^3-4165.89ft^3 \\ V=202.11ft^3 \end{gathered}[/tex]Since we need to express the solution in cubic yards we will use the following conversion factor:
[tex]1yd^3=27ft^3[/tex]Multiplying by the conversion factor we get:
[tex]202.11ft^3\times\frac{1yd^3}{27ft^3}=7.49yd^3[/tex]Therefore, 7.5 cubic yards are needed.

ANSWER
B. 8w - 10 = 174
EXPLANATION
The length of the rectangle is 5 less than 3 times the width.
Let the length be L.
Let the width be w.
This means that:
L = 3 * w - 5
L = 3w - 5
The perimeter of a rectangle is given as:
P = 2(L + w)
The perimeter of the rectangle is 174. This means that:
174 = 2L + 2w
Recall:
L = 3w - 5
=> 174 = 2(3w - 5) + 2w
174 = 6w - 10 + 2w
=> 8w - 10 = 174
That is Option B
Show all work to receive credit. Write verbal questions in at least one complete sentence.For each of the following questions, decide if the data is qualitative or quantitative. If it is quantitative, decide if it’s discrete or continuous. Explain the reason for your answer. a)Janelle is collecting data on the number of ounces of water drank by college students during a typical math class. What type of data is this?
To answer this question let's remember the definitions of qualitative and quantitative data:
• Qualitative data is data that describes the attributes or properties of what we are studying.
,• Quantitative data that describes certain quantity or amount. It is usually express by numbers with some unit associated it with it and it can be discrete or continuous. Discrete data is described by particular numbers in a range and continuos data is described by any number in any range.
With this in mind we conclude that Janelle is measuring qualitative data, since she is measuring the amount of water the student takes, furthermore this is continuous data since each student can drink any amount of water, that is, we can even divide the ounces in any decimal.

[tex]\begin{gathered} \frac{650900}{1000}=650.9\cong650 \\ \\ \text{ Therefore:} \\ 650\cdot9.6=6240 \end{gathered}[/tex]Now, this is the annual result, but since the payments are weekly and we know that there are 52 weeks in a year, then:
[tex]\begin{gathered} d=\frac{6240}{52} \\ \\ d=\text{ \$120} \end{gathered}[/tex]Which means that in each payment they deduct $120
