4. 5 pages
The answer is 5 pages because if Kosta read 1/4 of an 8 page chapter, she read 1/4*8 of a chapter, because of means multiply, which equals 2 pages. Add the three pages Christina read, and you'll get 2+3=5 pages.
6. 9 sections
The answer is 9 sections because eating 1/3 of the 12 sections means eating 12*1/3 of the sections, because of means multiply, which equals to 4, and if you add that to the sections you ate, you'll get 4+5=9 sections.
Hope this helped!
Given expression: − 11.50 (1.32 + 0.48).
We need to simplify it and get the answer in decimals.
Note: In order to simplify above given expression, we need to apply order to operations.
According to order to operations, we need to simplify parenthesis first.
So, we need to add 1.32 + 0.48 first.
1.32 + 0.48 = 1.80.
So, − 11.50 (1.32 + 0.48) would become -11.50(1.80).
Now, we need to multiply -11.50 by 1.80.
-11.50(1.80) = -20.7.
<h3>Therefore, final answer is -20.7.</h3>
Answer:
(a) 81st
=NORM.INV(0.81;0;1)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
(d) 24th
=NORM.INV(0.24;0;1)
(e) 11th
=NORM.INV(0.11;0;1)
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
For this case we can find the percentiles with the Norm.inv function in Excel and we got:
(a) 81st
=NORM.INV(0.81;0;1)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
(d) 24th
=NORM.INV(0.24;0;1)
(e) 11th
=NORM.INV(0.11;0;1)
Depends on how many she needs......
Based on the inventory on hand, the lead time, and the standard deviation, the in-stock probability will be 96.56%
<h3>What is the in-stock probability?</h3>
To find the in-stock probability, you first need to find the Z score as:
= On-hand inventory / Standard deviation x √(lead time + 1)
Solving gives:
= 5,050 / 800 x √(11 + 1)
= 5,050 / 2,771.28
= 1.82
With a Z score of 1.82, the probability according to the Z tables will be 96.56%
