Answer:
6,7,8,9,10
Step-by-step explanation:
Diameter = 4 inches
Radius = diameter/2 = 4/2 = 2 inches
Area = πr^2 = π(2)^2 = 4π = 12.57 inches squared approx.

u=kv
6=k(-7)
k=-6/7
u=kv
u =-6/7 * 4
u =-24/7
Answer: u = -24/7 or -3 3/7
Answer:
(a) Probability he or she will answer all 10 problems correctly is 0.5
(b) Probability he or she will answer at least 9 problems correctly is 0.95
Step-by-step explanation:
(a) Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 10 problems
Number of total outcomes = 20 problems
Probability he or she will get all 10 problems correctly = 10 ÷ 20 = 0.5
(b) Probability he or she gets at least 9 problems correctly means he or she either gets 9 or the 10 problems correctly
Probability he or she gets at least 9 problems correctly = (9÷ 20) + (10÷20) = 0.45+0.5 = 0.95
