What is the last one number 12
Answer:
3/3
Step-by-step explanation:
x2 minus x1 over y2 minus y1
Answer:
.3
Step-by-step explanation:
The probability distribution in the second row simply shows the probabilities for each number in the first row.
To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.
P(-5) = 0.15
P(0) = 0.05
P(5) = 0.1
0.15 + 0.05 + 0.1 = 0.3
Hiiii i just commented but it works now!
THE ANSWER IS: 9
let the length FJ be x
since the triangles are similar, set up a ratio that matches the corresponding sides
so the longest side of the triangle over the shortest side of the triangle
set the ratios equal to each other
to solve for 16+x, multiply 15x15 then divide by x
rewrite that as 225/x = 16+x
solve for x
you’ll get two answers: -25 and 9
since the side length can’t be negative, the answer is 9
Answer:
Out of a class of 8 boys and 4 girls, a group of 7 people is chosen at random.
Find the probability that the group of 7 includes one particular boy. Find the probability that the group of 7 includes at least 2 girls?
boys= 8
girls= 4
total= 12
probability that the group of 7 includes a boy= 8/12= 2/3
probability that the group of 7 includes at least 2 girls= 4/12= 1/3
