Answer:
x= -2
Step-by-step explanation:
7x-3=4x-9
3x-3= -9
3x= -6
x= -2
Answer:
What is the probability that a randomly selected person is on the swim team?
28 out of 67 people are on the swim team
so that's 28/67
41.7910448% round to the nearest tenth
41.8% is the answer.
Step-by-step explanation:
Volume of Cylinder A is pi times the area of the base times the height
π r2 h = (3.1416)(4)(4)(15) = 753.98 ft3
Volume of Cylinder B is likewise pi times the area of the base times the height
π r2 h = (3.1416)(6)(6)(7) = 791.68 ft3
After pumping all of Cyl A into Cyl B
there will remain empty space in B 791.68 – 753.98 = 37.7 ft3
The percentage this empty space is
of the entire volume is
37.7 / 791.68 = 0.0476 which is 4.8% when rounded to the nearest tenth
-6 < 3n + 1 < = 10
solve from the center out to both the left and the right. subtract 1
-7 < 3n <=9
divide by 3
-7/3 -7/3 = -2 1/3 so if we are to use INTEGERS ONLY that would have to be rounded to -2 because the inequality is saying x has to be GREATER than negative two and one third.
Checking: -6 < 3(-2) + 1 < = 10
-6 < -1 < = 10
I think I found the complete problem which is shown in the attached picture. The given function is a piecewise function.
So, from months 1 to 3, we follow the equation: y = -x + 8
@x = 1, y = -1 + 8 = 7
@x = 2, y = -2 + 8 = 6
@x = 3, y = -3 + 8 = 5
Then, from months 4 to 12, we follow the equation: y = x
@x = 4, y = 4
@x = 5, y = 5
And so on and so forth. Thus, the table of data should be:
x y
