Step-by-step explanation:
2 times a number, 2y
the sum of that and 9, 2y+9 ‘is’ 7
2y+9=7
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
D the slopes are negative reciprocals
Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
Check my math, as I just did it in my head
Roberta it would cost 52.80 for 22 wings
