Lets get started :)
2 + 2 + x - 7 = 21
11 + x = 21
We have to subtract 11 on both sides to isolate x
11 ( - 11 ) + x = 21 ( - 11 )
11 and 11 cancels out
x = 10

(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:
cups of flour.
Step-by-step explanation:
Given that:
is the number of cups of water to be mixed with flour for making tortillas.
is the number of cups of flour to be mixed with water for making tortillas.
Relation between
and
is given by the equation:

To find:
Number of cups of flour to be added if number of cups of water to be used is 1.
Solution:
We are given an equation with two variables.
Value of one variable is given and we have to find the value of other variable.

Number of cups of flour to be added =
