When rolling a fair, eight-sided number cube, determine P(number greater than 6).

0.25
0.50
0.66
0.75

Answers

0.75

Step-by-step explanation:

The most appropriate choice for probability of an event will be given by-

Probability of getting a number greater than 2 on a 8 sided die is 0.75

What is probability of an event?

Probability of an event gives the information about how likely an event is going to happen.

Probability is calculated by number of favourable outcomes divided by total number of outcomes.

Probability is always greater than or equal to zero and less than or equal to 1

Probability of unsure event is 0 and probability of sure event is 1.

Calculation

Here,

Favorable outcomes (Numbers greater than 2 on a eight - sided die) = {3, 4, 5, 6, 7, 8}

Number of favourable outcomes in rolling a 8 sided die = 6

Total number of outcomes in rolling a 8 sided die = 8

Probability of getting a number greater than 2 on a 8 sided die =

= 0.75

In an experiment, Mary will flip a coin 9 times. Will the relative frequency of her coin landing on heads be equal to the probability the coin will land on heads? How do you know?

yes because, it’s a 50-50 either way so it will be the same, unless your counting the fact whatever side faces up when you flip it is a tiny bit more likely (I’ve tried it before and it’s true! Whatever side is facing upwards is more likely!) that doesn’t count in math terms though.

Answers

Answer:

Let the tree be x, the puppies be y, and the flowers be z.

Given: x + 26 = 114

When finding x: x = 114 - 26

x = 88, Therefore the tree has a value of 88.

Given: y + y + y = 159

When finding y: 3y = 159

y = 159/3 = 53, Therefore the puppies have a value of 53 each.

Given: z - 26 = 200

When finding z: z = 200 + 26

z = 226, Therefore the flowers have a value of 226.

Step-by-step explanation:

h*h*h*h = h^4

j*j*j = j^3

thus answer is h^4 * j^3

Hi your answer would be h^4*j^3

Explanation:
There are 4 H’s being multiplied by themselves meaning it’s H to the 4th power then it’s the same process with J; J to the 3rd power. Finally you’d multiply H to the 4th and J to the 3rd. I hope this helps :)

70 faculty members at a school 14 of the faculty members are male. what percentage of the faculty is female? please show your work.

Answers

Answer: 80% of the faculty is female

Step-by-step explanation:

To find the percentage of the faculty that is female, we need to first determine how many faculty members are female.

Number of female faculty members = Total faculty members - Number of male faculty members

Number of female faculty members = 70 - 14

Number of female faculty members = 56

Now we can calculate the percentage of the faculty that is female by dividing the number of female faculty members by the total faculty members and multiplying by 100.

Percentage of female faculty members = (Number of female faculty members / Total faculty members) x 100

Percentage of female faculty members = (56 / 70) x 100

Percentage of female faculty members = 0.8 x 100

Percentage of female faculty members = 80%

Therefore, 80% of the faculty at this school is female.

Q1. A sample of students is taken from the school's A honor roll. The school estimates that there are 360 students on the A honor roll. Using the sample, how many students on the A honor roll are 8th graders?

Q2. If there are 360 students in the school on the A honor roll, how many students are 7th graders?

Answers

Q1: 126 students on the A honor roll are 8th graders. First you add 15+11+14. You get 40. Divide 360 by 40 you get 9. Multiply 9 by 14 that is 126.

Q2. 99 students on the A honor roll are 7th graders. You add 15+11+14=40. 360/40=9. 9 x 11 = 99.

Write an equivalent expression for 1/4 (8x + 32) - 7x - 14

Answers

Answer:

-(5 x + 6)

-5 x - 6

Step-by-step explanation:

You could choose one of those. While I was simplifying I got both of those. Let me know if both are correct or only one of them.

1/4 ( 8x + 32) - 7x - 14
= 1/4 . 8 (x + 4 ) - 7x - 14
= 2 ( x+ 4) - 7x - 14
= 2x + 8 - 7x - 14
= ( 2x - 7x) + ( 8 - 14 )
= -5x - 6 or - ( 5x + 6)
