Hello!
1.
The area of a rectangle is lenth * width
So 16 * 6 = 96
------------------------------------------------------------------------------------------------------
2.
The area of a square is a side^2
So 11^2 = 121
------------------------------------------------------------------------------------------------------
3.
The area of a parallelogram is base * height
So 14 * 9 = 126
------------------------------------------------------------------------------------------------------
4.
It is a parallelogram again
So 12 * 8 = 96
------------------------------------------------------------------------------------------------------
5.
The area of a triangle is
h is height and b is base
15 * 19 = 285
285/2 = 142.5
------------------------------------------------------------------------------------------------------
for number 6 I do not remember how to do that sorry
Hope this helps!<span />

Answer:
1.69% probability both are nervous around strangers.
24.31% probability at least one is nervous around strangers.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are nervous around strangers, or they are not. The people are chosen randomly, which means that the probability of a person being nervous around strangers is independent from other people. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
About 13% of the population of a large country is nervous around strangers.
This means that .
Two people are randomly selected
This means that .
What is the probability both are nervous around strangers?
This is
1.69% probability both are nervous around strangers.
What is the probability at least one is nervous around strangersnervous around strangers?
This is
24.31% probability at least one is nervous around strangers.
Remember that the point-slope form of a line is:
For a line with slope m and that passes through point (h,k)
Now, let's work on the line we're given. SInce the x-intercept is 6, we know that the line passes through (6,0).
Let's calculate the slope m :
Now, using point (5,3) we can get the following point-slope form for the line:
