Max tossed a fair coin 3 times. What is the probability of getting heads in the first two trials and tails in the last trial?
Answers
H=heads
T= Tails
HHH TTT
HHT TTH
HTH THT
HTT THH
Since 8 things can happen and only one of them is what you want, the probability is 1/8
Another way to think about it is each toss has 1/2 of coming up as you want it to.
Three tosses are 1/2 x 1/2 x 1/2 which is 1/8
You could get this answer by creating a tree diagram or by thinking about the possibilities that exist.
Realm of possibilities with one toss:
H or T.
Realm of possibilities with two tosses:
H, H
H, T
T, H
T, T
Realm of possibilities with three tosses:
H, H, H
H, H, T <--- 1/8 chance of taking place
H, T, T
T, T, T
T, T, H
T, H, H
T, H, T
H, T, H

PLEASE HELPPP!! Triangle HJK and triangle PMK are similar right triangles.The coordinates of all the vertices are integers.Which statement is true about the slope of HK and the slope of PK?A) The slope of HK is less than the slope of PK, because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for HK than it is for PK. B) The slope of HK is equal to the slope of PK, because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for HK as it is for PK. C) The slope of HK is greater than the slope of PK, because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for HK than it is for PK. D) The relationship between the slope of HK and the slope of PK cannot be determined, because the triangles are congruent.

Answer: Hello there!
The pairs in the table are: 3 carrots to 9 cucumbers, (dividing both sides by 3, we get 1 carrot to 3 cucumbers) wich has a ratio of 1:3.
after we got 4 carrots to 12 cucumbers, we could divide both sides by 4, and we also get a ratio of 1:3
And we can see this for all the pairs in the table, you always need to use cucumbers equal to three times the amount of carrots tat you used.
So if you use one carrot you need to use 3 cucumbers; wich ads to a total of 4 vegetables.
This is the less amount of vegetables that you can use because you can't use less than one carrot. (because you need to use whole vegetables)
Then the correct option is C.
Answer:
4
Step-by-step explanation:
The ratio of carrots to cucumber is 1:3.
The sum of their fewest amount is 4

we see that in D, we have 6x^2 which is quadratic, not linear
D is ansre
15. isolate y
emember you can do anything to an equaiton as long as you do it to both sides
12x-4y=20
add 4y to both sides
12x+4y-4y=20+4y
12x+0=4y+20
12x=4y+20
minus 20 both sides
12x-20=4y+20-20
12x-20=4y+0
12x-20=4y
divide both sides by 4
12/4x-20/4=4/4y
3x-5=1y
3x-5=y
y=3x-5
