Answer:
x = 7
Step-by-step explanation:
The segment marked 6x is the midline of the triangle, so is half the length of the base.
6x = 1/2(84)
x = 42/6 = 7
The value of x is 7.
Answer:
58%
Step-by-step explanation:
This is a problem of conditional probability.
Let A represent the event that student has dark hair.
So P(A) = 55% = 0.55
Let B represents the event that student has blue eyes.
So, P(B) = 60% = 0.60
Probability that student has blue eyes and dark hairs = P(A and B) = 35% = 0.35
We are to find the probability that a randomly selected student will have dark hair, given that the student has blue eyes. Using the given formula and values, we get:

Therefore, there is 0.58 or 58% probability that the student will have dark hairs, given that the student has blue eyes.
Answer:
2000
Step-by-step explanation:
Increase 1000 by 1000 in addition.
Modeled in an equation, the situation is 1000 + 1000.
1000 + 1000 = 2000
Answer:
3x-4
Step-by-step explanation:
y=ax+b general type of the line
a is the slope
y=3x+b
put 5 instead of the x and put 11 instead of the y
11=15+b
b=(-4)
Equation is 3x-4
