Answer:
Step-by-step explanation:
Since 2 triangle are similar
So sides of both triangle are equal
So 72/X=12/10
X= 72x10/12
=60
X=60 is the answer
In the given figure we have two similar triangles:
a) Triangle ABC
b) Triangle ADE
Two sides of triangle ABC are 2 and x
The two corresponding sides of triangle ADE are (2+1)=3 and 1
The ratio of corresponding sides of similar triangles is always equal, so we can write:
Therefore, the measure of x will be 2/3
Answer:
slope = 1
Step-by-step explanation:
slope = (y2 - y1)/( x2-x1)
slope = -2-3/-3-2
slope = -5/-5
slope = 1
Answer: The required probability is 0.615.
Step-by-step explanation:
Let A be the event that a product receives good reviews.
Let E₁ be the event that the product is highly successful.
Let E₂ be the event that the product is moderately successful.
Let E₃ be the event that the product is poor.

(a) What is the probability that a product attains a good review.
So, it becomes,

Hence, the required probability is 0.615.
Answer:
15/4.
Step-by-step explanation:
4th term = a1 r^3
= 30(1/2)^3
= 30/8
= 15/4.
