Since there are 1500 people in your random sample, and the statistics show that 19.9% of people in that bracket smoke, convert your decimal to a percent (divide by 100, so you would get 0.199) and multiply that by the number in your sample, 1500. This gives you 298.5. You cannot have a fraction of a person, so round up to 299 people.
There will be 54 students on the Track team.
1.) 0.09 x 600
2.) 54
To check this answer, follow these steps
1.) 54 divide by 600
2.) 0.09
That means 54 is 0.09% of 600
1: Subtract 15 from both sides. 5x=13.
2: Divide both sides by 5.
Answer: 2.6, which is equal to 13/5. The answer is B.
Answer:
(- 3, 4)
Step-by-step explanation:
given the 2 equations
2x - y = - 10 → (1)
y = 4 → (2)
Substitute y = 4 into (1) and solve for x
2x - 4 = - 10 ( add 4 to both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
solution is (- 3, 4 )
8- 42/y
