Answer:
The parent sine graph
has a range of -1 ≤ y ≤ 1
It crosses the x-axis x = 0° ± 180°n
The maximum points occur when x = 90° ± 360°n and y = 1
The minimum points occur when x = 270° ± 360°n and y = -1
The sketch the graph of function
we simply move the graph of
up 2 units.
So this means it will have a range of 1 ≤ y ≤ 3
It no longer crosses the x-axis.
The maximum points occur when x = 90° ± 360°n and y = 3
The minimum points occur when x = 270° ± 360°n and y = 1

It’s a 4/12 chance of rolling a 3 or 8
Answer:
2/3
Step-by-step explanation:
In the problem the question is How much longer so that means subtract.
10/12 - 1/6 =2/3
Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met
Unit rate for $40 for 100 books is $0.40 and the unit rate for $75 for 250 books is $0.30. so the $75 for 250 books is better. to find unit rate you do 40/100 and 75/250
