Answer:
7.1 cm^2
Step-by-step explanation:
Area = pie * radius^2
Area = pie * 1.5^2
= 7.0685
The probability for a football player to suffer more than three roken bones will be the the sum of probabilities for 4 broken bones and five broken bones. Looking at the chart provided we can see that the probablity for 4 four broken bones is P(4)=0.10, and for 5 broken bones is P(5)=0.15. Thus the probaility,
P(x>3)=0.10+0.15=0.25.
Answer:
351 adults and 275 students
Step-by-step explanation:
We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 626 tickets were purchased, then s+a=626.
We also know that 74 fewer student tickets then adult tickets. So s+76=a, the number of student tickets plus 76 will be the number of adult tickets.
We will solve by substituting one equation into the other. We substitute a=76+s into s+a=626. Simplify and isolate the variable a.
s+a=626
s+76+s=626
2s+76=626
2s+76-76=626-76
2s=550
s=275
This means that 275 students attended and 351 adults attended since 275+351=626.
Do you have answer choices or are they just fill in?
Answer:
RQ+SQ=RS
Step-by-step explanation:
Use the same reasoning as the first example. You could draw it if that helps.
R----------------------------Q-----------------------------S
RQ + SQ = RS
