Answer:

Step-by-step explanation:
We are given a triangle
whose sides are
a=12
b=8
c=13
Since, c is largest among them
So, angle C must be largest angle
we can find angle C
we can use law of cosine formula

now, we can plug values


now, we can find angle
we get

<span>29+10j= -11
</span><span>29+10j - 29 = -11 - 29 (subtract 29 to both sides)
10j = -40
10j/10 = -40/10 (divide both sides by 10)
j = -4

Answer: 0.27648
Step-by-step explanation:
Given : The proportion of all individuals have group A blood : p=0.040
Total individuals give blood : n= 6
Let X be the number of individuals have group A blood.
Since all individual are independent of each other.

Formula :
, where n= sample size , p = probability of getting success in each trial.
The probability that exactly three of the individuals have group A blood. :

The probability that exactly three of the individuals have group A blood. is 0.27648
ANSWER:
INFERENTIAL STATISTICS
STEP-STEP-BY EXPLANATION:
Inferential statistics are mathematical tools for estimating how likely it is that a statistical result based on data from a random sample is representative of the population from which the sample is assumed to have been selected.
It can make inferences from data to more general conditions like
* estimate the degree of confidence that can be placed in generalizations from a sample to the population from which the sample was drawn. (generalize your sample to a larger population)
