We have an equation: 27/?= 36/100
Cross multiply:
36*?= 27*100
⇒ ?= 27*100/36= 75
36% of 75 is 27~
Answer:
80% of the students would vote for Tammy
Step-by-step explanation:
Since a Kimberly took a sample of 30 students from the school and it was found that 24 students said they would vote for Tammy. To determine Kimberly's best estimate of the number of students in the school who would vote for Tammy, we divide the number of students that said they would vote for tammy by the total number of student sample.
number of students who would vote for Tammy = students who said would vote for sammy / number of sample = 24 / 30 = 4/5 = 80%
Answer:
6
Step-by-step explanation:
fred has 2 peanut butter and 3 jelly
type 1 peanut butter can go with all three types of jelly = 3 pb&js where ther is one constant peanutbutter and 3 different jellys
type 2 peanut butter can go with all three jellies = 3 pb&js where there is one constant peanutbutter and 3 different jellies
3+3=6
there are 6 peanut butter and jelly sandwhiches he could make.
you can also just multiply the numbers (2x3=6)
Answer:
The correct answer is b.
Step-by-step explanation:
The wave equation is given generally as:
c(x, t) = Acos(kx - wt)
Where A = amplitude
k = wave number
w = angular frequency.
x = horizontal distance moves by the wave.
t = time
The options show to us that the wave depends only on t and not (x, t).
Hence, the wave equation becomes:
c(t) = Acos(wt)
Given that:
A = 5 V
f = 1 * 10⁶ Hz
Angular Frequency, w, is given as:
w = 2πf
w = 2 * π * 1 * 10⁶ Hz
w = 2π(1 * 10⁶)
The wave equation becomes:
c(t) = 5cos(2*π*1*10⁶)
The correct answer is b.
