You would divide a side of the larger rectangle by the smaller rectangle and it would give an answer of 1.5. To check if your correct times your answer by one of the sides on the smaller triangle
Answer:y=1/6x+2
Step-by-step explanation:
Y=1/6x+b
Plug in (-6,1)
1=1/6(-6)+b
1=-1+b
Add 1 to both sides
1+1=b
2=b
Y=1/6x+2
Answer:
So we use the t-distribution to compute a confidence interval for the average age of people using online dating services
Step-by-step explanation:
Confidence interval for a mean.
We have to decide between the t-distribution and the z-distribution.
T-distribution: We use the sample standard deviation.
Z-distribution: We use the population standard deviation.
In this problem:
The average age of those that were using online dating services was 35 years old with a sample standard deviation of 12 years.
So we use the t-distribution to compute a confidence interval for the average age of people using online dating services
Answer:
x = -45
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides:
(x/5) * 5 = (-9) * 5
x = -9 * 5
x = -45
x = -45 is your answer.
