Write a cosine function that has an amplitude of 3, a midline of 2 and a period
1 answer:
Answer:
f(x) = 3 cos (2Pi / period value ; x )+ 2
or see answer using 2 as the period see answer in bold below.
Step-by-step explanation:
cosine function amplitude of 3 is A = 3
The period is used to find B
You need to show period value as the denominator and work out from there with 2PI as a function numerator to show as 2pi / period can be a data angle
C is the adding value.
Acos (Bx) + C
A = 3
Bx = 2 pi / period
C = + 2
However f 2 is also the period found
then we just plug in 2 to above formula
f(x) = 3 cos (2Pi / 2 ; x )+ 2
f(x) = 3cos (x pi) + 2

Answer:
(a) P(next ball with blue) = (b) P(Not to be red) =
(c) P(drawing 70 times yellow ball) = .
Step-by-step explanation:
Given that,
The total outcomes of the color of tile are :-
Red , Red, Blue, Yellow, Blue, Red, Green, Red, Blue, Green.
From the Question,
Total number of outcomes = 10
(a) What is the probability that her next draw will be blue ?
Red = 4,
Blue = 3,
Green = 2,
Yellow = 1.
P(next ball with blue) = .
(b) What is the probability that her next draw will NOT be red?
P(Red ball) =
But we have to find
P(Not to be red) =
(c) If Amy draws 70 more times with the same tiles from the question above, what probability would you expect a yellow?
P(Yellow ball) =
drawing it 70 times we get the probability
P(drawing 70 times yellow ball) = .
