First you add all of the numbers up and then divide by how many numbers there are.
average = sum of data/number of data
Average = 152/20
Average = 7.6
Answer:
24% probability that both fund A and fund B will rise in price
Step-by-step explanation:
We have these following probabilities:
40% probability that fund A will rise in price.
If fund B rises in price, 60% probability that fund B does.
What is the probability that both fund A and fund B will rise in price
40% of A, and if A rises, 60% is B. Since the only outcome that interests us is both rising in price, we multiply these probabilities
24% probability that both fund A and fund B will rise in price
We know that a supplementary angle is 180 degrees because they add up to 180 degrees.
To solve for x:
Add the whole numbers
7x + 33 + 70 = 180
Subtract 103 on both sides.
7x + 103 = 180
-103 -103
Divide 7 on both sides to get x alone.
7x = 77
--- ---
7 7
x = 11
Check:
7(11) + 33 + 70 = 180
77 + 33 + 70 = 180
110 + 70 = 180
180 = 180
The angle
7(11) + 33
77 + 33
equals to
110
Which means that the angle is 110 degrees.
If she read 21/40, this means that she hasn’t read 19 of the 40 chapters.
You can divide 19/40 to get the decimal
19/40=0.475
Hope this helps!! :)
