Answer:

10.82

Step-by-step explanation:

6^2+9^2=x

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

117=x^2

taking square root on both sides.

The Square root of 117 is 10.82.

Therefore the square root of the 117 is 10.82.

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

Answer: 1. 26

Step-by-step explanation:

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

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.

Answer:

40 shots total.

Step-by-step explanation:

First, change the percentage to a decimal:

80% = 80/100 = 0.80

Next, divide the amount of baskets made (32) with the decimal gotten to get the  total amount of shots:

32/0.80 = 40

Brandon took a total of 40 shots.

Check. Divide 32 (shots made) with the 40 (total shots in all):

32/40 = 0.8 = 80%.

Answer:

y=2/7x+19/7

Step-by-step explanation:

Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7

Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:

y=2/7x+b

3=2/7(1)+b

3=2/7+b

21/7=2/7+b

19/7=b

Therefore, our final equation is y=2/7x+19/7

Answer:

530.66 m²

Step-by-step explanation:

Area of circle= π×radius²

So the radius is 26/2= 13

13×13=169

So 3.14×169 would be the area

3.14×169= 530.66

(And if you have to round to the nearest tenth it would be 530.7)

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.

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:

Step-by-step explanation:

if its trying to find area for a circle then we use the formula A=πr²

A=π(3)²

A= 28.27 ft²

Answer:

the answer is 18.85ft

Step-by-step explanation:

the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:

C = 2πr

input the values you have into the formula

C= 2 x π x 3

(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)

put that into your calculator and youll get the answer

C= 18.8495559215

(i rounded the answer to two decimal places = 18.85ft)
