Answer:
x=44
Step-by-step explanation:
For the two lines to be parallel, the two angles have to add to 180 degrees
45+3x+3 =180
Combine like terms
3x+48 = 180
Subtract 48 from each side
3x+48-48=180-48
3x=132
Divide each side by 3
3x/3 = 132/3
x =44
Answer:
Using the t-distribution, the 99% confidence interval for the true average number of alcoholic drinks all UF female students (over 21) have in a one week period is (3.25, 4.85).
We have the standard deviation for the sample, thus, the t-distribution is used to solve this question.
First, we find the number of degrees of freedom, which is the sample size subtracted by 1, thus:
Then, using a calculator, with and 169 df, we have that the two-tailed critical value is .
The margin of error is:
In this problem, , then:
The confidence interval is:
In this problem, , then:
The confidence interval is (3.25, 4.85).
Step-by-step explanation:
6x and 2x have the same variable and are raised to the same power. That means that they are like terms and can be combined.
6x + 2x = (6 + 2)x = 8x
So, 8x is the answer.
Answer: So angle 1=117-59=58
Step-by-step explanation: Exterior angle(117)=sum of two remote interior angles(1+59)
Answer:true
Step-by-step explanation: because -3.2 is smaller than -3 because negatives get smaller the bigger the negative
