Answer:

cos(A) = 12/13

Step-by-step explanation:

There are several ways to remember trigonometric functions, but my personal favorite is:

SOH - CAH - TOA

Where Sin(angle) = Opposite/Hypotenuse

Cos(angle) = Adjacent/Hypotenuse

and Tan(angle) = Opposite/Adjacent

The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.

The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).

The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.

The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

Answer:

2/10

Step-by-step explanation:

just look at the table of outcomes to see how many have 3 or more 'T's

there are 2 of them out of 10

Answer:

The selection of r objects out of n is done in

many ways.

The total number of selections 10 that we can make from 6+7=13 students is  

thus, the sample space of the experiment is 286

A.  

"The probability that a randomly chosen team includes all 6 girls in the class."

total number of group of 10 which include all girls is C(7, 4), because the girls are fixed, and the remaining 4 is to be completed from the 7 boys, which can be done in C(7, 4) many ways.

P(all 6 girls chosen)=35/286=0.12

B.

"The probability that a randomly chosen team has 3 girls and 7 boys."

with the same logic as in A, the number of groups were all 7 boys are in, is  

so the probability is 20/286=0.07

C.

"The probability that a randomly chosen team has either 4 or 6 boys."

case 1: the team has 4 boys and 6 girls

this was already calculated in part A, it is 0.12.

case 2, the team has 6 boys and 4 girls.

there C(7, 6)*C(6, 4) ,many ways of doing this, because any selection of the boys which can be done in C(7, 6) ways, can be combined with any selection of the girls.  

the probability is 105/286=0.367

since  case 1 and case 2 are disjoint, that is either one or the other happen, then we add the probabilities:

0.12+0.367=0.487 (approximately = 0.49)

D.

"The probability that a randomly chosen team has 5 girls and 5 boys."

selecting 5 boys and 5 girls can be done in  

many ways,

so the probability is 126/286=0.44

36+81=117

Square root of 117 is 10.82

The value of the given side x  in the given circle is 10.82.

We have given that,

If necessary, round your answer to the nearest tenth. O is the center of the circle. The figure is not drawn to scale.

[tex]side^2+side^2=hypotenous^2[/tex]

6^2+9^2=x^2

36+81=117

The root of the quadratic equation x = -3/4[tex]\pm[/tex] √-31/ 4.

Suppose that we've a function y = f(x) such that f(x) is quadratic.

When y = 0, then the values of x for which f(x) = 0 is called solution of quadratic equation f(x) = 0

These solution gives values of x, and when we plot x and f(x), we'd see that the graph intersects the x-axis at its solution points.

Then its roots are given as

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Given; 2x^2 + 3x + 5 = 0

We know that a=2, b=3, c=5

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

[tex]x = \dfrac{-3\pm \sqrt{3^2 - 4(2) ( 5)}}{2(2)}\\\\\\x = \dfrac{-3\pm \sqrt{9 - 40}}{4}\\\\\\x = \dfrac{-3\pm \sqrt{-31}}{4}\\\\\\x = \dfrac{-3}{4}\pm \dfrac {\sqrt{-31}}{4}[/tex]

Answer: Negative

Step-by-step explanation: Since the values of A and B are both negative (because they are below 0), adding them together will also make the sum negative.

Answer:

Company A:

150 x 3 = $450

6/100 x 150 = $9

450 + 9 = $459

Company B:

3.10 x 150 = 465

4/100 x 150 = 6

465 + 6 = $471

Company C:

3.20 x 150 = $480

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

---------------------------

       23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

5x+2y =19

Substitute y=2

5x+2(2) =19

5x+4 = 19

Subtract 4 from each side

5x +4-4 =19-4

5x= 15

Divide by 5

5x/5 = 15/5

x=3

The solution is

The most reasonable prediction of the height of fifth-grade students is 55.

Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.

Given that,

Height of 10 students in 5th grade are 57, 54, 59, 53, 56, 54, 51, 56, 54, 56.

To determine the height of 5th grade students,

find average of all the data,

average = total height of students / total number of students

              = (57 + 54 + 59 + 53 + 56 + 54 + 51 + 56 + 54 + 56) / 10

              = 550 / 10

              = 55

The most reasonable prediction of the height of fifth-grade students is 55.

Answer and Step-by-step explanation:

As we can see by the given figure, we can cut out 2 rectangular prisms from this shape.

This gives us an easier time to find the volume. We will be using the volume formula for rectangular prisms: Length × Width × Height

The first prism has side lengths of:

Height = 6

Length = 11

Width = 7 (from the two 2's and the one 3 added together -- 2 + 2 + 3 = 7)

Let's multiply these values together.

6 × 11 × 7 =

66 × 7 =

462 -- First volume

The second prism has side lengths:

Height: 6

Length: 9

Width: 3

Let's multiply these values together.

3 × 6 × 9 =

3 × 56 =

168 -- Second volume

Now, we add together the volumes to get the volume of the composite figure.

168 + 462 = 630

The volume of the composite figure is 630 cubic feet.
