Answer:
4 : 1
Step-by-step explanation:
Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:
2² : 1² = 4 : 1 . . . . . . ratio of triangle areas
Answer:
P(-A) = 0.388
Step-by-step explanation:
By the <u> PROBABILITY POSTULATE: </u>
P(A) + P(not A) = 1
Here, P(A) = 0.612
So, P(not A) = P(-A) = 1 - 0.612 = 0.388
⇒P(-A) = 0.388
Answer:
x=−7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
