Answer:

45 ways

Step-by-step explanation:

The number of ways the committee of 2 can be selected from  a group of 10 may be found using the combination theory.

10 C 2

Recall that n C r = n!/(n-r)!r!

Hence

10 C 2 = 10!/(10 -2)!2!

= 10!/8!*2!

= 10 *9 *8!/8!* 2!

= 10 *9/2 * 1

= 90/2

= 45

45

-15<3n<-6 ÷3 → -5<n<-2

n = -4 , -3

Answer:

Step-by-step explanation:

Perimeter of the given polygon = n + 2 + 3 + 4 + n + 2 + 3 + 4

                                                     = 2(n + 2 + 3 + 4)

                                                     = 2(n + 9) units

Area of the composite figure = Area of rectangle A + Area of rectangle B + Area of rectangle C

                                                = (3 × 4) + (n ×2) + (2 × 3)

                                                = 12 + 2n + 6

                                                = 2n + 18

                                                = 2(n + 9) units²

Therefore, perimeter of the given figure = Area of the figure

Answer:

118 cm

Step-by-step explanation:

13 x 11 = 143

5 x 5 = 25

143 - 25 = 118

Answer: The second choice.

Step-by-step explanation: Everything greater than that value of y can satisfy the equation, which is why that whole area above is shared. The solid line means it is inclusive, which means it includes values along that line. The slope is 1/3 and the value of k is -1 because it is going down one unit.

Answer:

y=4x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-2)/(1-0)

m=4/1

m=4

y-y1=m(x-x1)

y-2=4(x-0)

y-2=4x

y=4x+2

Answer: [tex]41.67\ in.^3[/tex]

Step-by-step explanation:

Given

The side of the square base is 5 inches

height of the pyramid is 5 inches

The volume of a square pyramid is

[tex]V=\dfrac{1}{3}a^2h[/tex]

Putting the values

[tex]\Rightarrow V=\dfrac{1}{3}\times 5^2\times 5\\\\\Rightarrow V=41.67\ in.^3[/tex]

The pyramid contains [tex]41.67\ in.^3[/tex] of wood

Answer: y>(1/3)x-3

Step-by-step explanation: The slope is 1/3. The dotted line means it is not inclusive, and the value of k means it is going down three units.

Answer:

44.9

Step-by-step explanation:

Answer:

A:

probability of red = 4/16 = 1/4

prob(blue) = 7/16

probability of red, then blue is (1/4)(7/16) = 7/64

B:

probability red = 1/4

probability blue = 7/15

probability of red, then blue = (1/4)(7/15) = 7/60

c) your decision

Step-by-step explanation:

i took the test

The solution is,

A. 7/64 is the probability of selecting a red marble, replacing it, and then selecting a blue marble.

B. 7/60 is the probability of selecting a red marble, setting it aside, and then selecting a blue marble.

C. the answer is no.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given,

There are 4 red marbles.

There are 7 blue marbles.

There are 5 green marbles.

There are 16 marbles in total.

A:

Answer = (probability of selecting a red marble)(probability of selecting a blue marble)

First, the probability of selecting a red marble.

probability of red = 4/16 = 1/4

probability(blue) = 7/16

probability of red, then blue is (1/4)(7/16) = 7/64

B:

Answer = (probability of selecting a red marble)(probability of selecting a blue marble)

First, the probability of selecting a red marble.

probability red = 1/4

probability blue = 7/15

probability of red, then blue = (1/4)(7/15) = 7/60

c) obviously,

7/64 ≠ 7/60

So the answer is no.

Answer:

2

Step-by-step explanation:

Hey There!

When it ask for the scale factor its asking for what did you have to multiply the side length by of figure a to get the similar side length of figure b

for example in figure A the base length is 7

to get the the base length of figure B (14) they multiplied the base length of figure A by 2

7x2=14

therefore the scale factor is 2

Answer:

x = 27

Step-by-step explanation:

The little square at the bottom of the figure means that that angle is a right angle, or 90°. Knowing that it's a 90° angle and that one section of the adjacent angle is 63°, we just calculate 90-63 to get 27, the value of x.

Answer:

22

Step-by-step explanation:

Hey There!

So if you didn't know angle H is a right angle. So we are given two angles and they want us to find the missing angle

Remember all of the angles of a triangle add up to equal 180

so we subtract the given angles from 180 to find the missing angle

180-90-68=22

so we can conclude that angle G = 22

Answer:

25

Step-by-step explanation:

Step-by-step explanation:

We are given this function:

y=8700* (1.04)^{4}y=8700∗(1.04)

4

8700 is the initial amount.

1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.

1.04 * 100% = 104%

Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.

In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.

104% - 100% = 4%

This would be our solution if we don't have an exponent.

We have exponent so first step is to calculate the number and then we repeat the steps from above.

1.04^{4} = 1,169858561.04

4

=1,16985856

1,16985856 * 100% ≈ 116,99%

116.99% - 100% = 16.99%

So, final solution is growth of 16.99%

We are given this function:

y=8700* (1.04)^{4}y=8700∗(1.04)

4

8700 is the initial amount.

1.04 shows the change of original amount. This is decimal form of percentage. We need to transform it into regular percentage.

1.04 * 100% = 104%

Now we observe this number. If it is greater than 100% we have growth, if it is lower than 100% it is decay, and if it is equal to 100% than there is no change.

In our case this number is greater than 100% so we have growth. To determine the percentage rate we must substract 100% as it represents the original amount.

104% - 100% = 4

This would be our solution if we don't have an exponent.

We have exponent so first step is to calculate the number and then we repeat the steps from above.

1.04^{4} = 1,169858561.04

4

=1,16985856

1,16985856 * 100% ≈ 116,99%

116.99% - 100% = 16.99%

So, final solution is growth of 16.99%
