Answer: Combination

There are 56 committees possible

============================================

Explanation:

The reason why we know we'll use a combination (instead of a permutation) is because order does not matter. There are no ranking positions on a committee. No one person has a special job compared to the other. The ordering of a committee doesn't matter. All that matters is the entire group itself. For instance, if we had people A,B,C then the committee ABC is the same as CBA and BAC. We would have to introduce a different person, say person D, to get a new committee group.

We have n = 8 people overall to choose from and r = 5 slots to fill. Use the combination formula to get

[tex]_n C _r = \frac{n!}{r!*(n-r)!}\\\\_8 C _5 = \frac{8!}{5!*(8-5)!}\\\\_8 C _5 = \frac{8!}{5!*3!}\\\\_8 C _5 = \frac{8*7*6*5!}{5!*3!}\\\\_8 C _5 = \frac{8*7*6}{3!}\\\\_8 C _5 = \frac{8*7*6}{3*2*1}\\\\_8 C _5 = \frac{56*6}{6}\\\\_8 C _5 = 56\\\\[/tex]

We can conclude there are 56 different committees possible.

The answer is C.) (2, -5)

Answer:

x + 2y ≤ 12

x + 2y = 12

Step-by-step explanation:

The teachers can not give more than 12 hours of homework so this is the answer. those are the 2 equations you can use. It under 12 hours or equal to 12 hours.

Answer:

Part A: x + 2y ≤ 12.

Part B: y = -1/2x + 6.

Part C: (0, 0).

Step-by-step explanation:

Part A: The total hours of homework have to be 12 hours, and it has to be either 12 hours or less. So, we have ≤ 12.

They take 1 math course with x hours of homework, so in total, that is 1 * x = x hours of math homework.

They take 2 science courses with y hours of homework, so in total, that is 2 * y = 2y hours of science homework.

The inequality would then be x + 2y ≤ 12.

Part B: x + 2y = 12

2y = -x + 12

y = -1/2x + 6

You can  use the Math is Fun: Function Grapher and Calculator to find the graph of the line, shown below.

Part C: Since the inequality uses a ≤ symbol, we know that the shading will be underneath the line. An appropriate point below the line includes (0, 0). We will test out whether it works as a point included in the inequality.

x + 2y ≤ 12

0 + 2 * 0 ≤ 12

0 + 0 ≤ 12

0 ≤ 12

Since this is a true statement, (0, 0) holds true for the inequality.

Answer:

∠AOB and ∠COD are vertical angles

∠DOE and ∠COD are complementary, adjacent

∠AOB and ∠AOD are supplementary, adjacent.

Step-by-step explanation:

Let's start with ∠AOB and ∠COD.

Looking at this, we can see they are the same angles formed by two lines that intersected. These are vertical angles as they are opposite each other.

∠DOE and ∠COD together form the angle ∠EOC, which is a right angle. Complementary angles are any of two that add up to 90°, so these two angles are complementary. They are also adjacent because they are right next to each other.

∠AOB and ∠AOD together form the angle ∠BOD, which has a measure of 180°. Supplementary angles are any of two that add up to 180°, so ∠AOB and ∠AOD are supplementary. They are also adjacent as they are touching/right next to each other.

So if we think of a test tube, it looks sort of like a cylinder. This means that its cross-section would be a circle. To find out how many turns a piece of thread would make around the test tube, we need to find the circumference of the test tube, then divide the length of the string by the circumference.

Step 1) Find the circumference

C = pi x diameter

C = 3.14 x 3

C = 9.42

Step 2) Divide the length of the string by the circumference

90.42 / 9.42 = 9.5987

The string would make approximately 9.60 turns around the test tube.

Answer:

The proportion of college students who work​ year-round is 58%.

Step-by-step explanation:

The claim made by the education researcher is that 58​% of college students work​ year-round.

A random sample of 400 college​ students, 232 say they work​ year-round.

To test the researcher's claim use a one-proportion z-test.

The hypothesis can be defined as follows:

H₀: The proportion of college students who work​ year-round is 58%, i.e. p = 0.58.

Hₐ: The proportion of college students who work​ year-round is 58%, i.e. p ≠ 0.58. C

Compute the sample proportion as follows:

 [tex]\hat p=\frac{232}{400}=0.58[/tex]

Compute the test statistic value as follows:

 [tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}=\frac{0.58-0.58}{\sqrt{\frac{0.58(1-0.58)}{400}}}=0[/tex]

The test statistic value is 0.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected.

Compute the p-value for the two-tailed test as follows:

 [tex]p-value=2\times P(z<0)=2\times 0.5=1[/tex]

*Use a z-table for the probability.

The p-value of the test is 1.

The p-value of the test is very large when compared to the significance level.

The null hypothesis will not be rejected.

Thus, it can be concluded that the proportion of college students who work​ year-round is 58%.

Step-by-step explanation:

Use law of sines.

16 / sin 39° = BC / sin 120°

BC ≈ 22.02

Greetings from Brasil...

Here we cant use calculator..... It seems that in the USA the use of a scientific calculator is allowed

Let's use Senos Law in Any Triangle

(AC/SEN B) = (BC/SEN A)

16/SEN 39 = BC/SEN 120     sen 120 = sen 60 = √3/2

16/0,63 = BC/(√3/2)

0,63BC = 16√3/2

BC = 8√3/0,63

Answer: On the 20th day, he will give $5242.88

Step-by-step explanation: This is a geometric series with elements:

initial value ([tex]a_{0}[/tex]) = 0.01

ratio = 2

At the twentieth day means the 20th term, i.e. n = 20.

To determine that term, use the formula: [tex]a_{n} = a_{0}.r^{n-1}[/tex]

Substituing terms:

[tex]a_{20} = 0.01.2^{20-1}[/tex]

[tex]a_{20} = 0.01.2^{19}[/tex]

[tex]a_{20} = 0.01.524288[/tex]

[tex]a_{20} = 5242.88[/tex]

Then, on the 20th day, your uncle gave to you $5242.88

Answer:

(x - 1)² + (y - 2)² = 20

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given the endpoints, then the centre is at the midpoint

C = [ [tex]\frac{-3+5}{2}[/tex], [tex]\frac{0+4}{2}[/tex] ] = (1, 2 )

The radius is the distance from the centre to either of the 2 endpoints.

Use the distance formula to find r

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ )= (- 3, 0)

r = [tex]\sqrt{(-3-1)^2+(0-2)^2}[/tex]

  = [tex]\sqrt{(-4)^2+(-2)^2}[/tex]

  = [tex]\sqrt{16+4}[/tex]

  = [tex]\sqrt{20}[/tex]

Thus equation of circle is

(x - 1)² + (y - 2)² = ([tex]\sqrt{20}[/tex] )² , that is

(x - 1)² + (y - 2)² = 20

x = 1440/36 teaspoons.

x = 40 teaspoons

answer: C

Answer:

The correct option is;

False

Step-by-step explanation:

The coefficient of x^k·y^(n-k) is nk,   False

The kth coefficient of the binomial expansion, (x + y)ⁿ is  [tex]\dbinom{n}{k} = \dfrac{n!}{k!\cdot (n-k)!} = C(n,k)[/tex]

Where;

k = r - 1

r = The term in the series

For an example the expansion of (x + y)⁵, we have;

(x + y)⁵ = x⁵ + 5·x⁴·y + 10·x³·y² + 10·x²·y³ + 5·x·y⁴ + y⁵

The third term, (k = 3) coefficient is 10 while n×k = 3×5 = 15

Therefore, the coefficient of x^k·y^(n-k) for the expansion  (x + y)ⁿ = [tex]C(n,k)[/tex] not nk

Answer:

The answer is option 1.

Step-by-step explanation:

You have to apply Gradient formula :

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

[tex]let \: (x1 \: , \: y1) \: be \: ( - 2 \: , \: 0)[/tex]

[tex]let \: (x2 \: , \: y2) \: be \: (0 \: , \: 4)[/tex]

[tex]m = \frac{4 - 0}{0 - ( - 2)} [/tex]

[tex]m = \frac{4}{2} [/tex]

[tex]m = 2[/tex]

Answer:

2

Step-by-step explanation:

The formula you use to find the slope is

[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

First, you want to substitute

[tex]\frac{4-0}{0--2}[/tex]

Which simplifies to

[tex]\frac{4-0}{0+2}[/tex]

Because two negatives equal a positive

The next step is to add and subtract

[tex]\frac{4}{2}[/tex]

Which simplifies to

[tex]\frac{2}{1}[/tex]

Which equals

2.

Answer:

[tex]-24x^4+6x^3+25x^2+16[/tex]

Step 1:

We need to place the numbers in descending order of the power. Here, [tex]-24x^4[/tex] has the largest power, so that number goes first. We keep doing this until we end up with our final expression, placed in order based on the powers.

[tex]-24x^4+6x^3+25x^2+17-7+6[/tex]

Step 2:

We can see that the last three numbers, 17, -7, and 6, don't have variables or powers, so we simplify by adding (and subtracting) them.

[tex]17-7=10\\10+6=16[/tex]

Our final equation:
