Answer:

0.0816

Step-by-step explanation:

Given:

Let O = Students taking an online class

Let B = Students prefer watching baseball to football

Therefore,

P(O) = 1200/5000 = 0.24

P(B) = 1700/5000 = 0.34

If events O and B are independent,

⇒ P(O ∩ B) = P(O) · P(B)

                   = 0.24 × 0.34

                   = 0.0816

Answer:

10) 25π OR 78.5398...yd 11) 1/4π OR 0.785398...ft 12) 100π OR 314.159265....in

Step-by-step explanation:

area of a circle = πr^2 (π x radius squared)
the radius is just half the diameter

so for eg:

number 10)

diameter = 10 yd so radius = 5 yd

5 squared = 25

π x 25 yd = 25π OR 78.5398...yd

Answer:

b = 3/4

Step-by-step explanation:

The area of a triangle is given by

A = 1/2 bh

3/ 40 = 1/2 b ( 1/5)

Multiply

3/40 = 1/10 b

Multiply each side by 10

10 *3/40 = 10* 1/10 b

3/4 = b

Answer:

the median is 3.5

Step-by-step explanation:

there are 27  dots                                                                                                      27/2=13.5                                                                                                                 therefore the answer is the 13th dot and a half                                                              3.5 :)                                                                                                                                      (i dont know for sure but i think the mean is 3)

The mean is 3 and the median is 3 for this list of numbers.

From the dot pot,

Arrange the number in order:

1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5

Now,

Mean = Average of all the values.

Median = Midvalue of the number.

Now,

There are 30 numbers in the list, so the mean is:

Mean = 90/30 = 3

To find the median, we need to find the middle number.

Since there are an even number of numbers in the list, we take the average of the two middle numbers:

The middle two numbers are both 3, so the median is:

Median = (3 + 3)/2 = 3

Therefore,

The mean is 3 and the median is 3 for this list of numbers.

Answer:

  210 cm²

Step-by-step explanation:

The area of the triangle can be found using the triangle area formula:

  A = 1/2bh

  A = 1/2(12 cm)(35 cm) = 210 cm²

_____

Additional comment

The legs (short sides) of the right triangle are effectively the base and height of the triangle.

The area of the right angle triangle is 210 square centimeters if the side lengths are 12 cm, 35 cm, and 37cm

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

We have a right angle triangle with side lengths of 12cm, 35cm, and 36cm

Here the base length b = 12 cm

The height of the right angle triangle h = 35 cm

We know the formula for the area of the right angle triangle is given by:

[tex]\rm A = \frac{1}{2} bh[/tex]

[tex]\rm A = \frac{1}{2} \times 12\times 35[/tex]

A = 210 square centimeters

Thus, the area of the right angle triangle is 210 square centimeters if the side lengths are 12 cm, 35 cm, and 37cm

Answer:

There is not a slope perpendicular to the lie x = -6

Step-by-step explanation:

In this equation, you are given a line, x = -6.

This is in fact a line with an undefined slope. The slope for a perpendicular intersection is the opposite reciprocal of the slope.

Eg. If you have the line y = 2x

The reciprocal is y = 1/2x, the opposite means negative

So the slope that would intersect this line perpendicularly is y = -1/2x.

There is an undefined slope in this, therefore, you cannot find the slope for a line perpendicular to x = -6.

If it were an option, I would choose "no slope"

Answer:

670.21 inches^3

Step-by-step explanation:

To find the volume of the spheres, all you need to know is the formula for the volume of a sphere, which you've included in your problem. From the problem, you also know that r = 2. From here, you calculate the volume of 1 of the spheres, which turns out to be:

V = 33.51032

Since there are 20 spheres in this box, you multiple the volume of a single sphere by 20 to get the total volume occupied by the spheres.

V = 20 * 33.51032

V = 670.2064

If you round to 2 decimal places, this becomes 670.21.

Answer:

x = y = - 1

Step-by-step explanation:

y = - 2x - 3

y = 7x + 6 -----> equation 1.

So,

7x + 6 = - 2x - 3

7x + 2x = - 3 - 6

9x = - 9

Divide 9 on both sides,

9x / 9 = - 9 / 9

x = - 1

Substitute x = - 1 in equation 1,

y = 7x + 6

  = 7 ( - 1 ) + 6

  = - 7 + 6

  = 6 - 7

y = - 1

Therefore,

x = y = - 1

Answer:

m = - , c = -

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 3y + 4 = 0 ( subtract 2x + 4 from both sides )

3y = - 2x - 4 ( divide all terms by 3 )

y = - x - ← in slope- intercept form

with slope m = - and y- intercept c = -

Answer:

10°

Step-by-step explanation:

According remote interior angles, 4k + 5 + 6k + 10 = 115.

10k + 15 = 115

10k = 100

k = 10

Hope this helps :)

Have a nice day!

Answer:

k = 10°

Step-by-step explanation:

      According to the exterior angle theorem, the exterior angle will be equal to the two opposite inside angles added together. It will look like the following, and we solve for k from there.

115° = (4k + 5)° + (6k + 10)°

115° = 4k° + 5° + 6k° + 10°

115° = 6k° + 4k° + 10°  + 5°

115° = 10k° + 15°

100° = 10k°

10° = k

k = 10°

Answer:

x = t+ka/k

Step-by-step explanation:

First you take letter k and place it after =sign which brings (x-a) = t/k because if you shift any number or letter after the = sign it has to be the opposite sign. for instance if it's positive, it will turn negative after the equal sign and if it is multiplication, it will turn division

Then you open the brackets which makes x-a = t/k

Now you shift "a" after the equal sign which leads to our answer, x= t +ka/k

Answer:

x = [tex]\frac{t+ka}{k}[/tex]

Step-by-step explanation:

k(x - a) = t ← distribute parenthesis on the left side by k )

kx - ka = t ( add ka to both sides )

kx = t + ka ( divide both sides by k )

x = [tex]\frac{t+ka}{k}[/tex]
