When rolling a fair, eight-sided number cube, determine P(number greater than 6).
0.25
0.50
0.66
0.75
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

Tom's brother saw an advertisement for a special at Muscle Fitness. Membership is $15
monthly, with a mandatory additional $100 charge for equipment maintenance.
Tom saw on television that Platinum Gym was having a grand opening in a few months.
Tom is considering a membership at Platinum Gym. Platinum Gym charges a one-time
registration fee of $60, and membership is $20 a month.
Tom's brother tells him that the Muscle fitness deal is better than the one offered by
Platinum Gym. Is he correct?
(a) Write an expression to represent the membership cost of Muscle Fitness for x
months.
(b) Write an expression to represent the membership cost of Platinum Gym for x
months.
(b) At what month will both memberships cost the same overall? Show your work. (2
Answer:
80 - 20 = $60 for reservation and 15 + 20 every month 20 x + 60 + equal muscle fitness
Tom Brady was wrong the cost of line cost the same amount Platinum cost $20 a month and $60 for reservations as the muscle fitness there's no better deal or Worse still cost the same amount
Answer: A) 80 - 20 = $60 for registration and 15 + 5 = $20 every month. 20x + 60= cost of Muscle Fitness B) Tom's brother is wrong. They cost the same amount. Platinum Gym cost's $20 a month and $60 for registration as well as Muscle Fitness. There is no better deal or worse deal. They cost the same amount.

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.

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

At an office supply store, Samantha bought 5 notebooks and 2 pens for $9.
Jeffrey bought 3 notebooks and 2 pens for $6. Write a system of equations to represent this situation.
Answer: Let x be the cost of one notebook and y be the cost of one pen. Then we can write the following system of equations to represent the situation:
5x + 2y = 9
3x + 2y = 6
This system represents the fact that Samantha paid $9 for 5 notebooks and 2 pens, and Jeffrey paid $6 for 3 notebooks and 2 pens.
Step-by-step explanation:
Answer: hope this helps ♡
5x + 2x = 9
3x + 2x = 6
Step-by-step explanation:
x = cost of 1 item
Samantha → 5x + 2x = $9
Jeffrey → 3x + 2x = $6
5x + 2x = 9
3x + 2x = 6

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
