For this case we must simplify the following expression:
We must add similar terms taking into account that:
- Equal signs are added and the same sign is placed.
- Different signs are subtracted and the major sign is placed.
Thus, the simplified expression is:
Answer:
We know that
the addition rule states that
P(A or B) = P(A) + P(B) − P(A and B)
in this problem
P(A)=0.72
P(B)=0.84
P(A and B)=0.64
so
P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64
P(A or B) = 0.92
the answer is
0.92 (92%)
Answer:
y-3= -3/4 -(x+0)
Step-by-step explanation:
y2-y1 3-0= 3
x2-x1 0-4= -4
slope is - 3/4
y= mx=b
y = -3/4x + 3
Answer:
60
Step-by-step explanation:
To find the mean;
add up the data
(50+60+60+70) =240
Then divide by the number of data points
240/4 = 60
The mean is 60
