Answer:
J(x)=(-1x+4)^1/2
Step-by-step explanation:
Answer:
The angles are in the ratio of 2:3 and if you convert the ratio to units, the total units of the sum of the angles is 5 units. 5 units is thus equivalent to 90 and 1 unit is equivalent to 18. One angle is 2 units and hence is 36 degrees and the other angle is 3 units and hence is 54 degrees.
Answer:
The correct answer is 90
Step-by-step explanation:
17 + 36= z- 37 ADD 17 AND 36
53= z-37 BRING 37 OVER TO 53 AND ADD
z = 90 FINAL ANSWER
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
