Answer:
Required probability is 0.19
Step-by-step explanation:
The two-way table for the given data is,
Fiction Non-Fiction Total
9th grade 35 8 43
10th grade 52 12 64
Total 87 20 107
It is required to find the probability of the students who prefer to read non-fiction novels, given that they are in 9th grade.
That is, to find the conditional probability 
.
Now, 
So, we get,
<h3>Thus, the required probability is 0.19.</h3>
I do not have a video but to convert a fraction to a decimal, you divide the numerator by the denominator or make the denominator equal to one hundred. For example, to convert 1/5 to a decimal, you write 1/5 as 20/100, which as a decimal is written as .2
Answer:
Option c is correct !!
Step-by-step explanation:
[ Refer to the attachment ]
As y = mx + c is an equation to represent the straight line ; we equate the given line with this equation !!
Where m is slope of the line
and c is y intercept !!
We get , m = -3/2 and c = 4
Also, two perpendicular lines follows the equation :-
Where m nth is slope of nth line !!
Answer:
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
Hope this helps!
