Answer with Step-by-step explanation:
Contain Buy Do not contain Buy Total
Spam 48 12 60
Not Spam 4 36 40
P(it contains the word buy and it is spam)=48/100
P(It is spam)=60/100
Baye's theorem states that:
P(A given B)=P(A∩B)/P(B)
P( it contains the word buy, Given that an email is spam)
=P(it contains the word buy and it is spam)/P(It is spam)
= 0.48/0.60
=0.80
Hence, Correct option is:
A.] 0.80
Increasing the value of a would change the slope of the function specifically it would increase as well. Therefore, the line would be steeper than the original. The term ab represents the slope of the function and changing either one would result to the change of the steepness of the line.
Answer:
$7.50
Step-by-step explanation:
<u>If she is not a member:</u>
to print 350 pictures, she will pay 0.2 * 350 = $70
<u>If she IS a member:</u>
to print 350 pictures, she will pay 0.15(350) + 10 = $62.5
THus, the amount she saves is 70 - 62.5 = $7.50
