Answer:
Area of ΔPQR = 25 units
Step-by-step explanation:
We will use the following formula to calculate the area of triangle ΔPQR:
A = 1/2 | x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂) | = 1/2 |(-6(1+3) +2(-3-7) +(-1)((7-1)| =
A = 1/2 |-6 · 4 + 2 · (-10) + (-1) · 6| = 1/2 | -24-20-6| = 1/2 | -50| = 1/2 · 50 = 25
A = 25 units

Answer:
14 of the next twenty customers who place an order expected to order french fries
Step-by-step explanation:
For each customers, there are only two possible outcomes. Either they order french fries, or they do not order french fries. The probability of a customer ordering french fries is independent from other customers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
70% of the customers of a fast food chain order french fries
This means that
How many of the next twenty customers who place an order expected to order french fries?
This is E(X) when n = 20. So
14 of the next twenty customers who place an order expected to order french fries
