Answer:
1/3
Step-by-step explanation:
You need to use slope formula. (the change in Y over the change in X = Slope [x1-x2/y1-y2 = slope]). I believe you can also use point slope formula, but I forgot how to do that one.
First, you would set up the equation.
7-9/-2-4 OR 9-7/4+2
you would then solve to get
-2/-6 OR 2/6
when simplified you get
1/3
for both. Hope it helps!
Answer:
300
Step-by-step explanation:
a triangle has 3 sides and so perimeter is just adding all the sides together so the perimeter is 30 that means each side is ten so multiply those all by ten as it says and then they are all 100. add them to get 300, hope this helps :)
Answer:
yes it is
Step-by-step explanation:
plug x and y in
3 * 5 - 10 = 5 <== And this is true

Answer: The probability is 1/190 = 0.005
Step-by-step explanation:
The probability of ordering two specific toppings out of 20 is:
For the first selection he can order 2 of them, peperoni or sausage, so the probability for the first selection is 2/20 = 1/10 (the number of correct options divided by the total number of options)
For the second selection we have only one option, because we assume that the other one was selected previously, here we also had a total of 19 toppings because one already was selected, the probability in this selection is 1/19.
The joint probability is equal to the product of those two probabilities:
P = (1/19)*(1/10) = 1/190 = 0.005
