Answer:
There isn't enough buckets for all of the dirt to be in a bucket.
Step-by-step explanation:
From the question,
She has 20 buckets and would like to put 2.56 pounds of dirt into each bucket.
Hence, the total number of dirt that can be in the 20 buckets is
20 × 2.56
= 51.20 pounds of dirt
Slyvia has 51.76 pounds of dirt.
51.76 - 51.20
= 0.56 pounds of dirt.
From the above calculation we can say that there isn't enough buckets for all of the dirt to be in a bucket
Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form
f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9
Answer:
yes . The Expected value must always be one of its possible values of x
Step-by-step explanation:
<u>For example</u> :-
Alex's z score of 1.6 means her frequency of anxiety symptoms are 1.6 standard deviations more than the mean of all patients.
Z-score is defined as the relationship between a particular value or data to the mean of all the data present in a normal distribution. When the z-score is zero that means the data is equal to the mean.
where x=raw data,
=mean and
= standard deviation
Standard Deviation is a measure of how dispersed a data set is around its mean or central value. Numerically Standard deviation is defined as the square root of the variance of the distribution.
- Lower standard deviation means the data is clustered together
- A higher standard deviation means that the data is spread out over a larger area.
In the given problem as the z-score of Alex is given as 1.6, we can infer that the frequency of anxiety symptoms for Alex is 1.6 standard deviations more than the mean data.
Therefore from the above formula
