Step-by-step explanation:

break down the 3-D figure

Find area of triangle A=1/2bh

=1/2(8 inch)(6   9/10inch)

=1/2(8 inch)(69/10 inch)

=138/5 square inch

then multiply two because you have 2 triangles

=138/5 (2)  

= 276/5 square inch

= 55 1/5 sq.in

Find area of rectangle

A = lw

=6 1/4 in (8 in)

= 25/4 (8 in.)

= 50 sq. in.

then multiply by 3 because of the three rectangles

= 50 sq. inch (3)

= 150 sq. in.

Add all together

55 1/5 sq. inch + 150 sq. inch = 205 1/5 sq. inch

Step-by-step explanation:

The Pythagorean Theorem states that

[tex]a^2+b^2=c^2[/tex]

or that the two legs added together squared equal the hypotenuse squared

not: this only works with right triangles

Now Pythagorean triples are the set of sides that follow that rule

an example would be 3,4,5

why is it a Pythagorean triple?

well because it follows

[tex]a^2+b^2=c^2[/tex]

[tex]3^2=9\\4^2=16\\16+9=25\\5^2=25[/tex]

25=25

Answer:

C. 100°

Step-by-step explanation:

Line n || Line p and line t is their transversal.

Therefore,

[tex]m \angle 8 = 100 \degree \\ (corresponding \: \angle s)[/tex]

The measure of the angle ∠8 will be 100°. Then the correct option is C.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Two parallel lines are cut by a transversal.

Alternate angle - If two lines are parallel then the third line will make z -angle and z-angles are equal angles with the parallel lines.

The angle 4 and angle 5 are alternate angles.

∠5 = ∠4

∠5 = 100°

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

The angle 8 and angle 5 are vertically opposite angles.

∠8 = ∠5

∠8 = 100°

Thus, the measure of the angle ∠8 will be 100°.

Then the correct option is C.

Answer:

= 0.3478  

Step-by-step explanation:

Given:-

- The number of sophomore, S = 150

- The sophomore and had summer internship, x = 80

- The number of juniors, J = 200

- The junior and had summer internship, y = 150

Find:-

What is the probability that the person is a sophomore given that the person had a summer internship?

Solution:-

- The total sum of sophomore and junior students is N:

                        N = S + J

                        N = 150 + 200

                        N = 350 students.

- We will denote event A as random selection of sophomore from total.

- We will denote event B as random selection of student who had summer internship.

- We are to determine the conditional probability that a person selected is sophomore given that the person had a summer internship. That is the probability of event A given that event B has already occured.

- The conditional probability can be written as:

                       P ( A / B ) = P ( A & B ) / P ( B )

Where,

       P ( A & B ) : The probability the person is a sophomore and had a summer internship.

       P ( B ): The probability that the person selected had a summer internship.

                     P ( A & B ) = x / N

                                       = 80 / 350

                                       = 0.22857143

                    P ( B ) = ( x + y ) / N

                              = ( 80 + 150 ) / 350 = 230/350

                              = 0.65714286

Therefore the required probability is:

                    P ( A / B ) = 0.22857143 / 0.65714286

                                     = 0.3478  ... Answer

Answer:

56

Step-by-step explanation:

Hey There!

so this is a parallelogram so opposite angles are congruent

So basically what i am saying is that angle P is congruent to angle R

So we need to solve for x

We know that angle P and angle Q are supplements meaning that they will add up to 180

so we setup the equation

[tex]180=3x+5+8x-12\\[/tex]

step 1 combine like terms

[tex]3x+8x=11x\\5-12=-7[/tex]

now we have

180=11x-7

step 2 add 7 to each side

180+7=187

-7+7 cancels out

now we have

187=11x

step 2 divide each side by 11

187/11=17

x=17

now we plug in 17 to (3x+5) to get the value of angle R

17x3=51

51+5=56

therefore m∠R = 56

Answer:

0.2384 = 23.84% probability that 2 of the selected customers are financial services firms

Step-by-step explanation:

The customers are chosen from a sample without replacement, which means that the hypergeometric distribution is used.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

20 new customers have signed up for a specialized service your company provides.

This means that [tex]N = 20[/tex]

Twelve are financial services firms.

This means that [tex]k = 12[/tex]

Sample of 5

This means that [tex]n = 5[/tex]

What is the probability that 2 of the selected customers are financial services firms

This is P(X = 2).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 2) = h(2,20,5,12) = \frac{C_{12,2}*C_{8,3}}{C_{20,5}} = 0.2384[/tex]

0.2384 = 23.84% probability that 2 of the selected customers are financial services firms

It is a straight line through a rigid body when all its part are in rotation.

2. Cross section: the two-dimensional shape that results from cutting a three-dimensional shape with a plane. It is a internal view of an object that is made by cutting through it.

3. Solid of Revolution: the three-dimensional shape that is produced when a two-dimensional shape is rotated or revolved around a line. In mathematics, it is a solid shape that is obtained by revolving a curve around an axis.

Answer:

49.45mph

Step-by-step explanation

3 hours 28 min needs to be changed to decimal form so to do that we take 28/60 to get .466 so the new time for the second part of the trip is 3.466 hours.

from their you can add the distances of each part of the trip and divide that by the total time to get your average speed of 49.45mph

((rate1 x time1) + (rate2 x time2)) / (time1 + time2)

((37 x 2.1) + (57 x 3.466)) / (2.1 + 3.466)

(77.7 + 197.562)/ (5.566)

Answer:

Step-by-step explanation:

Neither linear nor exponential functions have a "wiggle" in their graph, so the piece in the region x < 0 is polynomial.

The piece in the interval [0, 3] is concave upward and has increasing slope. It could be polynomial, but is most likely the exponential piece of the function.

For x > 3, the function is linear.

There are no gaps in function value where the transition is made from one piece to another, so the function is continuous.

The function tends upward at the right side of the graph. It tends downward at the left side of the graph. This tells you the sign of the infinity they tend toward matches the sign of the infinity x tends toward.

__

On the interval [0, 3], h(x) is represented by an exponential function.

H(x) is a continuous function.

As x approaches +∞, h(x) approaches +∞.

As x approaches -∞, h(x) approaches -∞.
