Q1.
Perimeter = 2(Length + Width)
Perimeter =
Q2.
Answer:
x ≥ 0
y ≥ 0
x + y ≥ 5
29.50 × x + 43.00 × y ≤ 200
= 29.50x + 43y ≤ 200
Step-by-step explanation:
From the question we are told that:
If x and y represent the number of tickets Paige purchased for the 2 types of seats, Paige would like to attend at least 5 concerts.
The inequalities that models the situation above is given as:
x ≥ 0
y ≥ 0
x + y ≥ 5
Also from the question, we were told that: There are two types of seats at the concerts, which are priced at $29.50 and $43.00. Paige would like to attend at least 5 concerts and spend no more than $200.
The inequalities that models the situation above is given as:
29.50 × x + 43.00 × y ≤ 200
29.5x + 43y ≤ 200
Therefore, the system of inequalities that could Paige use to model this situation is:
x ≥ 0
y ≥ 0
x + y ≥ 5
29.50 × x + 43.00 × y ≤ 200
= 29.5x + 43y ≤ 200
Answer:
Correct option is b. Procedure results in a binomial distribution.
Step-by-step explanation:
Consider that <em>X</em> is Binomial random variable. The properties that are satisfied by <em>X</em> are:
- There are <em>n</em> independent trials.
- Each trial has only two outcomes: Success & Failure.
- Each trial has the same probability of success.
Suppose a roulette wheel is spun and the number of times the ball lands on '16' is observed.
If the random variable <em>X</em> is defined as the number of times the ball lands on '16', then the random variable <em>X</em> follows a Binomial distribution.
Because,
- Each spin is independent of each other
- Success: The ball lands on '16'
- Failure: The ball does not lands on '16'
- The probability of the ball landing on '16' is for each trial.
Thus, the correct option is b. Procedure results in a binomial distribution.
"Supplementary angles" means "angles add to 180 degrees"
So if x is one angle and 67 degrees is the other, and the two angles are supplementary, then x+67 = 180
The answer is choice A
