A. x>-5, that is greater than -5, so not this one
B. 5<x, that means x is bigger than 5, so not
C. x is greater than or equal to -10, so not this one
D. x is less than 10, so this one
D is answer
The value of z* should be used to construct a 97 confidence interval of a population mean is 2.17.
<h3>What is confidence interval?</h3>
A degree of uncertainty and certainty in a sample process is measured by confidence intervals. They can choose from a variety of probability limitations, the most frequent becoming a 95% or 99% confidence level.
Some characteristics of confidence interval are-
- Statistical tools, such as the t-test, are used to compute confidence intervals.
- Confidence intervals are used by statisticians to quantify uncertainty in such a sample variable.
- A researcher, for example, may randomly select multiple samples drawn from the same population and compute a confidence interval for every sample to determine how well it might represent the real value of a population variable.
- The generated datasets are all unique; some intervals contain the genuine population parameter while others do not.
Now, according to the question;
The confidence level is given 97%.
Thus, the crucial value of z for a 97% confidence interval is 2.17, as determined by a z score table, which is as follows:

Therefore the obtained probability for the z-score of 2.17 is 0.97.

Answer:
1.6
Step-by-step explanation:
First things first is to find what line QP corresponds with which is line MN
After that you find what multiplied into 5 would make it 2. The easiest way of ding so is to divide 2 by 5 which is 0.4. Now you want to find what line PR corresponds with which is OM. Now you multiply 4 (length of line OM) by 0.4 to find the length of line PR which is x. So now line PR is equal to 1.6 and x. Which also means that x=1.6
Answer:
510 ft²
Step-by-step explanation:
in the triangle
base (b) = 5 ft
height of the triangle (h1) = 12 ft
height of the prism = 15 ft
Now
Lateral surface area (LSA)
= perimeter of triangular base * height
= ( 13 + 5 + 12) * 15
= 450 ft²
Total surface area
= LSA + 2 * area of triangular base
= 450 + 2 * 1 / 2 * b * h1
= 450 + 5 * 12
= 450 + 60
= 510 ft²
