Answer:
Check the explanation
Step-by-step explanation:
1. The level of education as high school diploma (31% area).
Therefore the most frequent education level is High school Diploma.
2. Suppose there are 200 people in random sample. Pie diagram shows the percentage of people with Bachelor's degree is 19%
Therefore the number of people having Bachelor's degree among 200 people = 200×19% = 38
Therefore the answer is 38 .
3. Now the population size given is 6000. The percentage of individuals who have some collage but no degree is 17%
Therefore the number of individuals among 6000 individuals who have some collage but no degree = 6000×17% = 1020
Thereforethe answer is 1020 .
4. The percentage of individuals who have an associate's degree is 9% as per the pie diagram. The above pie diagram is based on a random sample of individuals. If we take another sample then also we may get different result. Therefore if we considere the entire population of U.S.A. the percentage of individuals who have an associate's degree may differ from 9% .
Answer: 2 can go into 120 60 times.
Step-by-step explanation:
120/2 = 60
Solve your system of equations step by step.
x−2y=14;x+3y=9
Solve x−2y=14 for x:
x−2y+2y=14+2y (Add 2y to both sides)
x=2y+14
Substitute (2y+14) for x in x+3y=9:
x+3y=9
2y+14+3y=9
5y+14=9(Simplify both sides of the equation)
5y+14+−14=9+−14 (Add -14 to both sides)
5y=−5
5y5=−55 (Divide both sides by 5)
y=−1
Substitute (−1) for y in x=2y+14:
x=2y+14
x=(2)(−1)+14
x=12(Simplify both sides of the equation)
So,
y=-1
x=12
Answer is C)
Answer:
Step-by-step explanation:
Where a graph intersects the x-axis is where the solutions or zeros of the quadratic are found...where y = 0.
If the points of intersection are x = -1 and x = 3, then putting those into factors gives us (x + 1)(x - 3) = 0. FOIL that out to get the quadratic.
which simplifies to
Looks like the third option there.
