Answer:
1.716*10^-3
Step-by-step explanation:
(4.4*10^-6)*(3.9*10^2)=0.001716
To convert 0.001716, we need to move the decimal places three places to the right to make sure the number is between 1 and 10. Moving three places to the right makes the exponent negative.
The principal will donate 1.50 for every dollar the fifth graders raise
The correct answer is 1 + 3i.
In order to get the answer to this, only add like terms. Add first the constants in the front.
3 + -2 = 1
Now add the imaginary terms
-5i + 8i = 3i
Then you can put the two together as a term and write as 1 + 3i.
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
