The surface area of the composite figure shown is 356 square feet. So, option b) is correct.

Surface area is the total area covered by the surface of the figure.

Given, the composite figure can be converted into two figures as shown in the image attached below:

Total Surface area of the composite figure= Area of figure 1 +  Area of figure 2.

Area of figure 1= Area of I+ Area of G+ Area of H+ Area of F

Area of I= Area of G

= Area of triangle

[tex]=\dfrac{1}{2}b\times h[/tex]

=7 x 4/2

=14

Area of I= Area of G

=8 x 4/2

=16

Area of figure 1= 14+14+16+16

Area of figure 1=60 sq feet

Area of figure 2 = Area of A+Area of B+Area of C+Area of D+Area of E

Area of rectangle=l x b

Area of A=Area of B=Area of D

=7 X 8

=56

Area of C=Area of E

=8 X 8

=64

Area of figure 2 = 56+56+64+56+64

Area of figure 2 = 296 sq feet

Surface area of the composite figure=296+60

=356 square feet

Thus, surface area of the composite figure is 356 square feet. So, option b) is correct.

Answer: D arccsc(x) = arcsin(1/x)

Step-by-step explanation:

The correct equation is arccsc(x) = arcsin(1/x), as it represents the inverse relationship between the cosecant and sine functions, indicating that arccsc(x) finds the angle whose sine is the reciprocal of x.

The correct equation related to arcsecant is arccsc(x) = arcsin(1/x). The arcsecant function, arccsc(x), is the inverse of the cosecant function, csc(x), which is the reciprocal of the sine function, sin(x). Therefore, arccsc(x) is used to find the angle whose cosecant is x. Since csc(x) = 1/sin(x), taking the inverse of both sides, we get arccsc(1/sin(x)) = x. By further manipulation, we can say that arccsc(x) = arcsin(1/x) because we are essentially finding the angle whose sine is the reciprocal of x.

The equation arccsc(x) = 1/sin(x) suggests a relationship between arccsc and the sine function directly, but this would imply that arccsc(x) gives us the value of 1/sin(x), which is not the case. The correct interpretation is that arccsc finds the angle whose cosecant (which is 1/sin(x)) is x, hence the equation arccsc(x) = arcsin(1/x).

Answer:

Volume of the pipe = 423.9cm³

Step-by-step explanation:

Width = 6cm = diameter

Radius (r) = d / 2 = 6 / 2 = 3cm

Height = 15cm

Volume = ?

π = 3.14

Assuming the shape of the pipe is that of a cylinder, then we can easily find its volume just by calculating the volume of the cylinder.

Volume of a cylinder = πr²h

π = 3.14

r = radius of the cylinder

h = height of the cylinder

Volume = 3.14 × 3² × 15

Volume = 3.14 × 9 × 15

Volume = 423.9cm³

The volume of the pipe is 423.9cm³

The volume of the given pipe is [tex]424.12\ cm^3[/tex].

To calculate the volume of the pipe, assume the pipe is cylindrical and use the formula for the volume of a cylinder. The formula is given by:

[tex]V = Area\ of\ cross\ section \times height[/tex]

Since the pipe is cylindrical, the cross section is a circle. Therefore:

[tex]Area\ of\ cross\ section = \pi r^2[/tex]

where r = radius of cross section

Given width = 6 cm = diameter of the cross section = 2r

[tex]2r = 6\ cm \implies r = \frac{6}{2}\ cm = 3\ cm[/tex]

Therefore:

[tex]Area\ of\ cross\ section=A = \pi r^2 = \pi (3)^2 = 9\pi\ cm^2[/tex]

Assuming the 'height' mentioned is the length through which fluid is flowing, and given the cross-sectional area, the volume formula simplifies to:

[tex]V = A\times h[/tex]

Given height (length of cylinder) = 15 cm:

[tex]V = 9\pi \times 15\ cm^3 = 135\pi \ cm^3 \approx 424.12\ cm^3[/tex]

So, the volume of the pipe, assuming it as cylindrical, is [tex]424.12\ cm^3[/tex].

Answer:

perfect negative correlation

Step-by-step explanation:

correlation coefficient is the term used in statistic which provides the information of strength of relation between two variables. This value suggests if there is change in value of one variable, what will be the change in the variable and how much will value of that change.

What will be the change : it suggest whether change in value of one variable other will be increase or decrease .

If there is increase in one variable and other also increases it suggest there is positive correlation .

If there is decrease in one variable and other also decrease it suggest there is positive correlation .

how much will value of that change: It means to say if there is change in one variable by how much amount other variable will change.

If the value of correlation coefficient is high it means that  change in value   for one variable is high in to  response change in other variable .

It values ranges from -1 to +1 high

while sign depicts type of relation that is positive or negative .

value from - 1 to + 1 depicts strength of the relation .

with - 1 depicting  perfect negative correlation

+1   depicting perfect positive correlation.

In the problem it is given correlation coefficient is 1 which means it is positive and value of one means that if there x percentage increase in one variable then other variable will also increase by x percentage and vice versa.

Answer:

[tex]n=\frac{0.93(1-0.93)}{(\frac{0.09}{1.96})^2}=30.875[/tex]  

And rounded up we have that n=31

Step-by-step explanation:

First we need to find the critical value for the margin of error desired. The confidence level is 0.95 so then the significance is [tex]\alpha=1-0.95=0.05[/tex] and the critical value for this case would be:

[tex] z_{\alpha/2} =\pm 1.96[/tex]

The margin of error for the proportion interval is given by this formula:  

[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]    (a)  

And on this case we have that [tex]ME =\pm 0.09[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex]   (b)  

The estimated proportion for this case is [tex]\hat p =0.93[/tex]. And replacing into equation (b) the values from part a we got:

[tex]n=\frac{0.93(1-0.93)}{(\frac{0.09}{1.96})^2}=30.875[/tex]  

And rounded up we have that n=31

Step-by-step explanation:

We have been an image of a triangular pyramid. We are asked to find the volume of the given pyramid.

We know that volume of triangular pyramid is [tex]\frac{1}{3}b\cdot h[/tex], where,

b = Base area,

h = Height of pyramid.

We can see that base of pyramid a right triangle.

[tex]\text{Area of triangle}=\frac{1}{2}\times\text{Base}\times\text{Height}[/tex]

Now we will find height of base triangle using Pythagoras theorem.

[tex]h^2=30^2-24^2[/tex]

[tex]h^2=900-576[/tex]

[tex]h^2=324[/tex]

[tex]\sqrt{h^2}=\sqrt{324}[/tex]

[tex]h=18[/tex]

[tex]\text{Area of base triangle}=\frac{1}{2}\times24\times 18[/tex]

[tex]\text{Area of base triangle}=12\times 18[/tex]

[tex]\text{Area of base triangle}=216[/tex]

[tex]\text{Volume of triangular prism}=\frac{1}{3}b\cdot h[/tex]

[tex]\text{Volume of triangular prism}=\frac{1}{3}\cdot 216\cdot 30[/tex]

[tex]\text{Volume of triangular prism}=216\cdot 10[/tex]

[tex]\text{Volume of triangular prism}=2160[/tex]

Therefore, the volume of the given prism is [tex]2160\text{ m}^3[/tex] and option B is the correct choice.

Answer: 6.4 In decimal form.  32/5 in fraction form.

Step-by-step explanation:

So first times 8 by 12 which is 96

then, 3 times 5 which is 15

Simplify to 32/5

Answer: 32/5

Step-by-step explanation: When multiplying two fractions together, remember that we can cross-cancel.

In this problem the 12 and 3 reduce to 4 and 1.

So we have 8/1 · 4/5.

Next we simply multiply across the numerators and multiply across the denominators and we have our answer which is 32/5.

Answer:

m = 40.5

Step-by-step explanation:

21/8.1 = 105/m

Croos multiplying the fractions, we get

21m = 850.5

m = 850.5/21

m = 40.5

hope it helps!

To solve the proportion 21/8.1 = 105/m, cross-multiply to get 21m = 850.5. Then, divide both sides by 21 to find m = 40.5.

To solve the equation 21/8.1 = 105/m, you can use cross-multiplication. By setting up the proportions correctly, you ensure that meters, being the only unit involved, is properly handled in the calculations.

First, cross-multiply to get 21 * m = 105 * 8.1. This simplifies to 21m = 850.5. Next, divide both sides of the equation by 21 to isolate m on one side, leaving you with m = 850.5 / 21. Upon dividing, you get m = 40.5.

It's important to remember that when dealing with ratios or proportions, canceling equivalent terms in the numerator and denominator simplifies the problem, making it easier to solve. Moreover, understanding how to deal with powers of 10 is essential, such as knowing that for 105/103 = 105-3 = 102 is helpful in many mathematical problems.

Answer:

90 squared is 8,100, and 120 squared is 14,400. So to figure out what c is you do 90^2 + 120^2 = Square Root of 22,500 which is 150.

So c = 150

Step-by-step explanation:

So C=150

hope this helps :D

By using the Pythagorean theorem, we will see that side C measures 150ft.

We can see that side C is the hypotenuse of a right triangle. We know both catheti of said triangle, then we can use the Pythagorean theorem.

It says that the sum of the squares of the cathetus is equal to the square of the hypotenuse. Then we have:

A^2 + B^2  = C^2

We know that:

A = 90ft

B = 120ft

Replacing that we get:

√((90ft)^2 + (120ft)^2) = C = 150ft

Then we conclude that side C measures 150ft.

Answer:

6 weeks

Step-by-step explanation:

You can use linear equations to find this out.

y is the total amount saves, x is the number of weeks.

Jade's equation: y = 5x + 0 (the 5 is how much she will save each week, the 0 is how much she has now, or the initial value.)

Enrique's equation: y = 3x + 12 (the 3 is how much he will save each week, the 12 is how much he has now, or the initial value.)

You can set up a table, or you could enter it in your calculator.

After entering the equations in my calculator, I found that the x value of 6 was when both equations had the same y value. So after 6 weeks, both of them had saved 30 dollars.

Step-by-step explanation:

8+12+14+6=40

8+6=14

p( pizza or steak)=14/40=0.35

0.35*100=35%

The experimental probability is the occurrence probability of an event concerning all events. The experimental probability of pizza or steak is P(P or B) = 35%

The experimental probability is a probability assigned to an event. It is the number of times an event occurs concerning the number of times all events occur or the experiment is repeated.

It can be calculated by taking the relative frequency of the event when the experiment is repeated several times.

To calculate it, we can use the following formula,

P(E) = Number of trials performed in which a certain event occurred / Total number of trials in which all events occurred

In the exposed example,

steaks.

P(E) = Number of trials performed in which a certain event occurred / Total number of trials in which all events occurred

P(P or B) = (8 + 6) / (8 + 12 + 14 + 6) = 14 / 40 = 0.35 = 35%

The experimental probability of pizza or steak is P(P or B) = 35%
