Answer:
The tree diagram is shown in the tree diagram is shown.
If the probability to hit is 0.7, then the probability to miss is 0.3.
P(hit, hit) = 0.7*0.7 = 0.49
P(hit, miss) = 0.7*0.3 = 0.21
P(miss, hit) = 0.3*0.7 = 0.21
P(miss, miss) = 0.3*0.3 = 0.09
Answer:
Problem:
180-144=36
36/2=18
A=18
Step-by-step explanation:
The full area of half of a circle is equal to 180 degrees. To find the missing value of both A's you must take the full degrees of 180 and subtract 144 from 180. Next you have to take the remaining number and divide it by two because both of the missing value's are equivalent.
Circle Circumference= 2πr
Diameter is given, but the formula requires the radius.
Radius= diameter ÷ 2= 1/2 ÷ 2= 1/2 * 1/2= 1/4= 0.25
C= circumference
π= 3.14
C= 2πr
substitute in numbers
C= 2(3.14)(.25)
C= 1.57 rounded to 1.6 miles
ANSWER: 1.6 miles
Hope this helps! :)
It would be 68 students more because if you subtract 17 from 85 you would get 68
