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.

If you multiply 2 times $2.00, you get $4.00. If you add $2.00 and $2.00 you get $4.00. If you multiply 3 times $1.50, you get $4.50. If you add $3.00 to $1.50 you also get $4.50. If you multiply 5 times $1.25 you get $6.25. If you add $5.00 to $1.25 you also get $6.25. Six times what amount of money would give the same amount as $6.00 added to that amount?

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

Step-by-step explanation:
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

You are looking for the price of 4 pairs of shoes after 20 days of being on sale. You have $100 and you have to find out whether you can buy these shoes.
How to solve:
After 20 days 1 pair of shoes will cost:
$40/1 x 2/5 = 16$
40-16 = 24
So 1 pair of shoes will cost $24 after 20 days.
24x4 = $96
4 pairs of shoes after 20 days cost $96. We have 100$, So we will be able to purchase it.

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
