38.8 is the answer. Using pemdas you should find work leading to that
Answer:
the solution is (4, 1).
Step-by-step explanation:
The goal here is to "solve this system of linear equations." You need to share that along with the equations.
We can begin the solution by substituting 3y + 1 for x in the second equation:
2(3y + 1) + 4y = 12
Performing the multiplication, we get 6y + 2 + 4y = 12, or 10y = 10.
Then y must be 1.
Substituting 1 for y in the first equation, we get x = 3(1) + 1 = 4
Thus, the solution is (4, 1).
Answer:
d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
Step-by-step explanation:
Confidence interval of a proportion p.
We build a confidence interval at the x% level from a sample.
With this, we can say that we are x% sure that the true population propotion is in the interval.
The 95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true population proportion is between 0.53 and 0.59.
So the correct answer is:
d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
$4.00 + $2.25* number of miles
$4.00 + $2.25* 8.7= $23.58
6/8 simplifies to 3/4.
Divide both numbers by 2 and you can then simplify.
