The Volume and the surface area of the given figure are 87 in³ and 83 in²  

To find the volume of the figure, we need to split it into smaller rectangular parts and find the volume of each part separately. From the given measurements, we can see that the figure consists of three rectangular parts:

The volume of each part can be found using the formula:

Volume = length x width x height

Part 1: A rectangular prism with dimensions 3 in x 3 in x 1 in

Volume = 3 in x 3 in x 1 in

Volume = 9 in³

Part 2: A rectangular prism with dimensions 1 in x 6 in x 7 in

Volume = 1 in x 6 in x 7 in

Volume = 42 in³

Part 3: A rectangular prism with dimensions 6 in x 6 in x 1 in

Volume = 6 in x 6 in x 1 in

Volume = 36 in³

Total Volume:

The total volume of the piecewise rectangular figure is the sum of the volumes of each part:

Total Volume = Volume of Part 1 + Volume of Part 2 + Volume of Part 3

= 9 in³ + 42 in³ + 36 in³

= 87 in³

To find the surface area of the figure, we need to find the area of each face and add them up. The figure has 6 rectangular faces, and the area of each face can be found using the formula:

Area = length x width

Part 1:

Top and Bottom faces:

Area = 3 in x 3 in

Area = 9 in²

Side faces:

Area = 3 in x 1 in

Area = 3 in² (x2)

Total Area of Part 1:

Total Area = 9 in² + (3 in² x 2)

= 15 in²

Part 2:

Top and Bottom faces:

Area = 1 in x 6 in

Area = 6 in²

Side faces:

Area = 1 in x 7 in

Area = 7 in² (x2)

Total Area of Part 2:

Total Area = 6 in² + (7 in² x 2)

= 20 in²

Part 3:

Top and Bottom faces:

Area = 6 in x 6 in

Area = 36 in²

Side faces:

Area = 6 in x 1 in

Area = 6 in² (x2)

Total Area of Part 3:

Total Area = 36 in² + (6 in² x 2)

= 48 in²

Total Surface Area:

The total surface area of the figure is the sum of the areas of all its faces:

Total Surface Area = Total Area of Part 1 + Total Area of Part 2 + Total Area of Part 3

= 15 in² + 20 in² + 48 in²

= 83 in²

The Volume and the surface area of the given figure are 87 in³ and 83 in²

Answer:

2 because 2 minus 1 equals one which means q= 2

after 4 females leave the team, the percentage of remaining team members who are male is 60%.

Initially, the team has 34 members with 18 males and 34 - 18 = 16 females. If 4 females leave the team, the number of females becomes 16 - 4 = 12. The number of remaining team members is 34 - 4 = 30 (since 4 members left).

To calculate the percentage of remaining team members who are male, we divide the number of males (18) by the total number of remaining team members (30) and multiply by 100:

Percentage of remaining team members who are male = (18 / 30) * 100 = 60%

Therefore, after 4 females leave the team, the percentage of remaining team members who are male is 60%.

To make a decision for the hypothesis test, we need to analyze the ANOVA summary table for the test of significance of the overall regression model.

From the table, we can see that the regression sum of squares (SS) is given as 20, and the residual sum of squares (SS) is given as 400. We also know that the total sum of squares (SS) is the sum of the regression SS and the residual SS.

Since the degrees of freedom (df) for the regression model is equal to the number of predictor variables (k) minus 1 (k - 1), and the df for the residual is the total sample size (n) minus the number of predictor variables (k), we can calculate the df for the regression and the residual.

Given that the sample size (n) is 45 and the number of predictor variables (k) is 4, we can calculate:

df for regression = k - 1 = 4 - 1 = 3

df for residual = n - k = 45 - 4 = 41

Next, we need to calculate the mean square (MS) for the regression and the residual by dividing the SS by their respective degrees of freedom.

MS for regression = SS for regression / df for regression = 20 / 3

MS for residual = SS for residual / df for residual = 400 / 41

Finally, we can calculate the F-statistic by dividing the MS for regression by the MS for residual.

F = (MS for regression) / (MS for residual)

Now, we can compare the calculated F-statistic to the critical F-value at the given significance level (α = 0.05). If the calculated F-statistic is greater than the critical F-value, we reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

Without the information of the critical F-value or the calculated F-statistic, we cannot make a definitive decision or final conclusion for the hypothesis test. Please provide the necessary values, and I will be able to help you with the decision and conclusion.

After 15 more years of contributions of $4,000 at the end of each quarter, the retirement account will be worth approximately $760,514.47.

To calculate this, we need to use the formula for the future value of a lump sum. A lump sum is a one-time payment made at the beginning or end of a specific period. In this case, we're looking at the future value of the retirement account after 15 more years of contributions.

Using the given information, we can plug in the values and solve for FV:

PV = $150,000

Pmt = $4,000

r = 10%

n = 4 (since interest is compounded quarterly)

t = 15 years

First, we need to calculate the future value of the current investment of $150,000:

FV1 = $150,000 x (1 + 0.1/4)⁴ ˣ ¹⁵ = $548,534.24

Then, we can calculate the future value of the quarterly contributions of $4,000 over 15 years:

FV2 = $4,000 x [(1 + 0.1/4)⁶⁰ - 1] / (0.1/4) = $211,980.23

Finally, we can add FV1 and FV2 to get the total future value of the retirement account after 15 more years:

Total FV = FV1 + FV2 = $548,534.24 + $211,980.23 = $760,514.47

Liam has 19 chairs.

Let x be the number of chairs Liam has.

According to the problem, x = 4a + 3 and x = 2b + 19 for some integers a and b.

Equating these two expressions, we get:

4a + 3 = 2b + 19

4a - 2b = 16

2a - b = 8

Therefore, b = 2a - 8.

Substituting this expression for b into x = 2b + 19, we get:

x = 4a + 35

Now, since x = 4a + 3, we have:

4a + 3 = 4a + 35 - 32

Therefore, x = 4a + 35 = 2(2a + 4) + 3 = 2b + 19, where a = 4 and b = 11.

Thus, Liam has x = 4a + 3 = 4(4) + 3 = 19 chairs.

The solution to this problem involves the use of two key mathematical concepts: algebraic equations and systems of equations.

We are given two equations in terms of the same variable x, each representing a different way of arranging chairs. By setting these two equations equal to each other, we obtain an equation in terms of x that allows us to find a value of x that satisfies both of the original equations simultaneously. This process of setting two equations equal to each other is an example of solving a system of equations.

To solve the resulting equation, we use algebraic manipulation to isolate the variable x on one side of the equation. This involves a combination of simplification, substitution, and rearrangement of terms. Ultimately, we arrive at a specific value of x that satisfies both equations, which is the answer to the problem.

c. Present value of $400 per year for 7 years at 0%: $2,800
d. Present value of $400 per year for 14 years at 14% (annuity due): $2,943.07

  Present value of $400 per year for 7 years at 0% (annuity due): $2,800

To find the present values of the ordinary annuities, we can use the formula for the present value of an annuity:

PV = PMT * [(1 - (1 + r)^(-n)) / r]
Where:
PV = Present value
PMT = Payment per period
r = Interest rate per period
n = Number of periods

a. $400 per year for 14 years at 14%:
PV = $400 * [(1 - (1 + 0.14)^(-14)) / 0.14]

≈ $2,702.83

b. $200 per year for 7 years at 7%:
PV = $200 * [(1 - (1 + 0.07)^(-7)) / 0.07]

≈ $1,155.54

c. $400 per year for 7 years at 0%:
Since the interest rate is 0%, the present value is simply the total amount of payments over the 7 years:
PV = $400 * 7

= $2,800

d. Reworking previous parts assuming they are annuities due:
For annuities due, we need to adjust the formula by multiplying it by (1 + r):

a. Present value of $400 per year for 14 years at 14%:
PV = $400 * [(1 - (1 + 0.14)^(-14)) / 0.14] * (1 + 0.14)

≈ $2,943.07

b. Present value of $200 per year for 7 years at 7%:
PV = $200 * [(1 - (1 + 0.07)^(-7)) / 0.07] * (1 + 0.07)

≈ $1,233.24

c. Present value of $400 per year for 7 years at 0%:
Since the interest rate is 0%, the present value remains the same:
PV = $400 * 7

= $2,800

In conclusion:
a. Present value of $400 per year for 14 years at 14%: $2,702.83
b. Present value of $200 per year for 7 years at 7%: $1,155.54
c. Present value of $400 per year for 7 years at 0%: $2,800

Step-by-step explanation:

3p + q = 8 and

3p - q = 10

then p+q is?​

--------

add up side-by-side:

6p=18 ⇒ p=3

q=8-3p= 8 - 9= -1

p+q= 3-1=2

Answer:

2

Step-by-step explanation:

3p + q = 8

3p - q = 10

→ Minus the two equations away from each other which would cancel out 3p

2q = -2

→ Divide both sides by 2 to isolate q

q = -1

→ Substitute q = -1 back into 3p + q = 8

3p - 1 = 8

→ Add 1 to both sides to isolate p

3p = 9

→ Divide both sides by 3 to isolate p

p = 3

⇒ The question asks us to find p + q so,

3 + - 1

→ Remember the minus cancels out the plus

3 - 1 = 2

Answer: p= -5

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

carry the one over to the right side and subtract it to get an amount of -10.

then carry the -4p to the left and add it with -2p. which comes out to be 2p

now the equation reads as 2p=-10

continue to divide 2 to get p alone and divide -10 by 2 as well.

now p=-5 because a negative divided by a postive is a negative.
