A coach needs to choose two players from the
hockey team to be captain and assistant
captain. If there are 20 players on the team,
how many ways he can assign the two roles?
A. 100
B. 190
C. 380
D. 450

Answer:

30:9

Step-by-step explanation:

Answer:

`a) $697.90

b) $161.98 gain

c) 23.2096% annual return rate

Step-by-step explanation:

a) $16.45 for one share. 42 shares will cost 16.45 x 42 = $690.90

As she used a broker and paid $7, the total cost for Tarah would be $697.90

b) After the investment, Tarah's gain is $20.64 per stock and she had bought 42. So the total income would be 20.64 x 42 = $866.88. However, she used a broker to sell the stocks as well, so the total gain would only be 859.88.

Overall, the cost was -697.90+859.88 = 161.98 net gain.

c) The rate of return would be the percentage of the original price of stocks that is equal to the net gain. What we are trying to find here is:

What percentage of 697.90 is 161.98?

We can find this percentage by doing a simple division (161.98/697.90) which gives us an answer of 0.232096

In percentages, multiply this decimal by 100 to get a 23.2096% annual return.

I hope I am correct, but some of the vocabularies may have messed up my answers. Hope it helps!

Answer: A

Step-by-step explanation:

Answer: B. 1 yard, 2 feet, 24 inches

Step-by-step explanation: 1 yard is 36 inches. Each feet is 12 inches, but there are 2 feet so 12 times 2 is 24 inches. And the last is just 24 inches. So, 36 + 24 + 24 = 84 inches

Answer:

Negative correlation

Step-by-step explanation:

Correlation analysis is used to measure the type and degree of relationship which exists between two or more independent variables. Relationship between variables may be classed as Negative or positive depending on the nature or behavior of one variable relative to the other. Positive relationship exists when an increase on one variable leads to a corresponding increase in the other other variable.

However, in the scenario described above, handicap decreases with player quality that is the better a player is, the lower the handicap ; similarly, a player with higher handicap with have low quality, this is Hence a classic scenario of Negative correlation or relationship.

Answer:

the correct answer is 6x^4

Answer:

(5, - 7 )

Step-by-step explanation:

A translation rule of

(x, y ) → (x + 1, y - 3 )

means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate, that is

(4, - 4 ) → (4 + 1, - 4 - 3 ) → (5, - 7 )

Answer:

(b, -a)

Step-by-step explanation:

First note that the rule for a rotation by 270° about the origin is (x,y)→(y,−x)

Note that the coordinates were swapped and the x coordinates negated. Similarly;

Given the coordinate of the point U as (a, b), if the triangle is rotated 270degrees clockwise, the resulting coordinate will  be (b, -a)

Answer:

the account balance after 17 years is $27,981.02

Step-by-step explanation:

Given that

The deposited amount i.e. $9,000

The Rate of interest is 6.9%

Time period = 17 years

We need to find out the account balance after 17 years

As we know that

Future value = Present value × (1 + rate of interest)^time period

= $9,000 × (1 + 6.9%)^17

=  $27,981.02

Hence, the account balance after 17 years is $27,981.02

Answer:

volume = 549.5 cm³

Step-by-step explanation:

base area m= πr² = (3.14)(5²) = 78.5 cm²

volume = base area x height = 78.5 x 7 = 549.5 cm³

Answer:

549.5 cm3

Step-by-step explanation:

Answer:

Center: (0, 6); radius = 4

Step-by-step explanation:

x^2 + y^2 - 12y + 20 = 0

We must complete the square in y.

x^2 + y^2 - 12y = -20

x^2 + y^2 - 12y + 36 = -20 + 36

x^2 + (y - 6)^2 = 16

(x - 0)^2 + (y - 6)^2 = 4^2

Center: (0, 6); radius = 4

Answer:

6 * 2/3 = 12/3 = 4

Step-by-step explanation.

you can think about it like this:  6 * 1/3 * 2

1/3 of 6 is 2 because 2 * 3 is 6

2 * 2 is 4, therefore the correct answer is 4

remember doing 6 * 2/3 is the same as doing 6/1 * 2/3 if that helps

Answer:

-3 across the x

Step-by-step explanation:

negative 3 is in the middle of the two, both between point -1 and -5, and point 0 and -6.

When a shape is reflected, it must be reflected over a line. The line of reflection of quadrilateral ABCD onto quadrilateral A'B'C'D is [tex]y = -3[/tex]

From the given graph, we have the following observations

Using points C and C' as reference;

We have:

[tex]C = (-3,-1)[/tex]

[tex]C' = (-3,-5)[/tex]

Notice that both points have the same x-coordinate

This means that the line of reflection is parallel to the x-axis, and it passes through the y-axis.

The point at which it passes through the y-axis is calculated using mid-point formula.

So, we have:

[tex]y = \frac{y_1 + y_2}{2}[/tex]

[tex]y = \frac{-1-5}{2}[/tex]

[tex]y = \frac{-6}{2}[/tex]

[tex]y = -3[/tex]

Hence, the line of reflection is [tex]y = -3[/tex]

See attachment for the line of reflection

Answer:

The length of the wooden board is about 12.2 feet.

Step-by-step explanation:

Please refer to the diagram attached below.

The base of the board forms a 35° degree angle with the ground.

And we want to find the length of the wooden board.

Since we are given an angle and its adjacent length and we want to find the hypotenuse, we can use the cosine ratio:

[tex]\displaystyle \cos(\theta^\circ)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]

The adjacent side is the distance from the wall to the board, which is 10 feet.

And the angle made is 35°.

The hypotenuse is the length of the wooden board. Therefore:

[tex]\displaystyle \cos(35)=\frac{10}{\ell}[/tex]

Solve for the length. Cross-multiply:

[tex]\displaystyle 10=\ell \cos(35)[/tex]

Therefore:

[tex]\displaystyle \ell=\frac{10}{\cos(35)}\approx12.2[/tex]

The length of the wooden board is about 12.2 feet.

Mean= Sumof all the numbers/ number of data

So,

23+37+11+58+13+45=187

Now...

187/6=31.166666667 Answer

hope it helps....

What is the mean of this data: 23, 37, 11, 58, 13, 45.

To find the mean of this data, first of all we should add up all the given numbers and then divide by how many numbers there are.

So, [tex] \bf Mean \: = \frac{23 \: + \: 37 \: + \: 11 \: + \: 58 \: + \: 13 \: + \: 45}{6} [/tex]

[tex] \bf Mean \: = \frac{187}{6} [/tex]

[tex] \bf Mean \: = \: 31.17 [/tex]

Answer:

$10,857.8

Step-by-step explanation:

Brad wants to have $17000 available to buy a car in 5 years. How much should he deposit now at 9% compounded monthly to reach that goal?

A = p(1 + r/n)^nt

P = A / (1 + r/n)^nt

P = 17000 / (1 + 0.09/12)^(12*5)

= 17,0000 / (1 + 0.0075)^60

= 17,000 / (1.0075)^60

= 17,000 / 1.5657

= 10,857.8

P = $10,857.8
