Answer:
D. All three functions have the same minimum value
Step-by-step explanation:
f(x) = -3 sin (x-pi) +2
Sin has a minimum value of -1, but since it is multiplied by a negative, we want its maximum value
sin has a maximum of 1
f (min) = -3(1) +2 = -1
g(x) has a minimum at x =3
g(minimum) = -1
h(x) = (x+7)^2 -1
The smallest a squared value can be is zero
= 0 -1
h(min) =-1
Answer:
x = 22/25
Step-by-step explanation:
Given
2 1/5 x
---------- = -----------
10 4
Using cross products
2 1/5 * 4 = x*10
Change 2 1/5 to an improper fraction
2 1/5 =(5*2+1)/5 = 11/5
11/5 *4 = 10x
44/5 =10x
Multiply each side by 1/10 to isolate x
44/5 *1/10 = 10x * 1/10
44/50 = x
Divide top and bottom by 2
22/25 = x

Answer:

Step-by-step explanation:
From the question we are told that:
Percentage of student to get A 
Sample size 
Generally Number of student to get A is



Therefore
Probability that one student gets an A grade is mathematically by





25+15=40, so to find percent of voters for candidate B you do 25/40 multiplied by 100.
