Answer:
(b)0.56
(c)0.38
Step-by-step explanation:
(a)The tree diagram is attached.
P(Ben Fails)=1-0.8=0.2
P(Tom Fails)=1-0.7=0.3
(b)Probability that both will pass their driving test.
P(both will pass)=0.8 X 0.7 =0.56
(c)Probability that only one of them will pass their driving test.
P(Tom Bass, Ben Fails OR Ben Pass, Tom Fails)
=(0.7 X 0.2)+(0.8 X 0.3)
=0.14+0.24
=0.38
Step-by-step explanation:
= √2x × √8x³
= √(2.8x^4)
= √16x^4
= 4x²
Answer:
b
Step-by-step explanation:
The general equation for a circle is:
where (h,k) is center of circle
r = radius
For this example, from the graph you see the center is at (0,-3) and radius is 2.
h = 0, k = -3, r = 2
Sub into general equation:
