Answer:

a) 16.5 inches

b) 1.64 radian

c) 22.3feet

Step-by-step explanation:

s = rθ \:

a) r = 3in

θ = 5.5rad

s = 3 × 5.5

= 16.5in

b) s = 6.4in

r = 3.9in

6.4 = 3.9 × θ

θ = 1.64rad (3sf)

arc=  \frac{θ}{360}  \times 2 \: \pi \: r

c) θ = 126°

arc = 49ft

49 = (126÷360)×2×3.142×r

r = 49 ÷ 2.1994

= 22.3ft (3sf)

(Correct me if i am wrong)

This is a probabilty, problem

firstly, let us bring out the sample space and size

the sample space is

9 apples,

5 bananas,

1 orange, and

5 peaches

The sample size is (9+5+1+5)= 20    

The probability of picking a banana is

Pr(banana) =5/20

=1/4

The probability of picking an apple

Pr(apple) = 9/20

The probability of picking up a banana and an apple with replacement is

=1/4+9/20

=9/80
