To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 17.16 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 17.16 is 100%, so we can write it down as 17.16 = 100%.
4. We know, that x is 62.4% of the output value, so we can write it down as x=62.4%
5. Now we have two simple questions:
1) 17.16 = 100%
2) x=62.4%
Where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
17.16÷x=100%÷62.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 62.4% of 17.16
17.16÷x=100/62.4%
(17.16÷x)×x=(100÷62.4%)×x
17.16=1.60256410256×x
(1.60256410256) to get x
17.16÷1.60256410256=x
10.70784=x
x=10.70784
Now we have:
62.4% of 17.16=10.70784
So 10.70784 is your answer
Hope this helps :)
(a) We need to figure out the deciles for a normal distribution curve in this part.
In order to do so, we need to find the z score corresponding to probability 0.10 and 0.90 on the normal distribution curve.
Upon looking at the normal distribution table, we can see that the probability P = 0.10 corresponds to a z score of -1.28 and probability P = 0.90 corresponds to a z score of 1.28.
Therefore, deciles are -1.28 and 1.28 for a normal distribution curve.
(b) In this part, we are given that mean height is 69.5 inches and standard deviation in height is 2.7 inches. Therefore, we can find the deciles using the z score formula as shown below:
Therefore, the required deciles are 66.044 and 72.956
Answer:
b=1/2
Step-by-step explanation:
2logb - 3logb = log8b - log4b
log
- log
= log8b - log4b
log(
) = log(2)
∴1/b = 2
∴b = 1/2
Answer:What’s the question-
Step-by-step explanation:9-4 and greater than -19? Oh 5 because 9-4=5 but it’s greater than -19 because -19 is a negative number.
