in a bag there are 10 balls numbered 1 to 10 A ball is picked at random find the probability of picking the following
(a) number 7
(b) an odd number
(c) an even number
(d) an prime number​

Answers

Answer 1

Answer:

a) 1/10

b) 1/2

c) 1/2

d) 2/5

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Total event/Total sample space

Since there are ten ball in the bag numbered 1 to 10

S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

n(S) = 10

Total sample space = 10

a) If we are to get the probability of picking the number 7.

(E) = {7}

n(E) = 1

Event = 1

Pr(picking 7) = 1/10

b) a) If we are to get the probability of picking an odd number

(E) = {1, 3, 5, 7 , 9}

n(E) = 5

Event = 5

Pr(an odd number) = 5/10 = 1/2

c) a) If we are to get the probability of picking an even number

(E) = {2, 4, 6, 8,10}

n(E) = 5

Event = 5

Pr(an even number) = 5/10 = 1/2

d) a) If we are to get the probability of picking prime

(E) = {2, 3, 5, 7}

n(E) = 4

Event = 4

Pr(prime) = 4/10 = 2/5

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a point 'p' which is a fixed point.

Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.

The new triangle formed is triangle A'B'C'.

From the figure, we can clearly see that the angle APA' is a right-angle triangle.

m∠APA' = 90°

Thus, the value of angle APA' is 90°.

Answer:

Step-by-step explanation:

Well first you should rearrange the equation to make it easier to graph. 8x-4y=16.

8x - 4y = 16.

8x +4y = 16 + 4y

8x -16 = 4y

Divide both sides by 4 to get y by itself.

2x - 4 = y

The y-intercept is -8 and the slope is 2x so the graph would look something like this.

the metal bar/random line is almost the same size as the other two sides of the triangle. if one side is 32ft, then the opposite side is 32ft also. the bottom is 100ft, so we could eliminate C. because it couldnt be that number. now the bottom triangle, one side is 40ft so the other side has to be 40ft as well. its asking about the metal bar.

its either:

A. 53.2ft     or

B. 44.4

because the line is almost the same size as 32ft. its almost a equallateral triangle. i would go with A. though because if you imagine the line at the bottom of the line (100ft.) the line would go over half of it (and 53.2 is over half of 100) so i would say

A.53.2

To see if it is possible, you will want to create an equation.

3(4x+2) = 6(2x+2)

As you can see, you will need to use the distributive property for this equation.

12x + 6 = 12x + 12

Remove 6 from both sides.

12x = 12x + 6

Divide 12 by both sides

x = x + 0.5

Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer:

113.04 cubic inches

Step-by-step explanation:

First lets identify the equation to find the volume of a cone.

V= [tex]\pi[/tex] r^2 h/3

Next we'll plug in height and radius

h = 3

r = 6

V = [tex]\pi[/tex] 6^2 * 3/3

V = [tex]\pi[/tex] 36 * 3/3

V = [tex]\pi[/tex] 36 * 1

V = [tex]\pi[/tex] 36

V = 36[tex]\pi[/tex]

Now we'll use 3.14 for [tex]\pi[/tex] and times it by the 36

V = 36[tex]\pi[/tex]

V = 113.04

V= 113.04 cubic inches

Whitch of the following number is between 2/5 and 7/8

Answers

Answer:

The correct answer is B.

Lets go through explaination:

According to the question, the answer should be between 2/5 and 7/8

If we changed the fraction into decimal, we will get 2/5 as 0.4 and 7/8 as 0.875

So now, we have to get the numbers in between 0.4 and 0.875

Changing all the fraction in the form of decimal:

15/16 = 0.93753/4 = 0.753/8 = 0.3751/3 = 0.33333333333......

In the above answers, only no. B is between 2/5 and 7/8.

So, B is the correct answer.

The owner where your work explains that you're paid $8/hour and receives a $25 bonus each month for being the manager. If the owner hands you a check for $250, How many hours did you work this month? Write an equation and solve.

Answers

Answer:

28.125 hours

Step-by-step explanation:

Amount of money paid per hour = $8

Bonus of being a manager = $25

Total amount of money paid = $250

To find:

Number of hours worked for this month?

Solution:

Let the number of hours worked = [tex]h[/tex] hours

Amount of money paid for [tex]h[/tex] hours = $8[tex]h[/tex]

As per question statement:

Bonus + Amount of money paid for [tex]h[/tex] hours = $250

[tex]25 + 8h = 250\\\Rightarrow 8h = 250 -25\\\Rightarrow 8h = 225\\\Rightarrow h =\dfrac{225}{8}\\\Rightarrow \bold{h = 28.125\ hours}[/tex]

Therefore, the answer is:

Number of hours worked = 28.125 hours
