Answer:
1/10.
Step-by-step explanation:
Prob(Spinning a 1) = 1/5.
Prob(Flipping a Head) = 1/2.
Probability of a 1 then a head = 1/5 * 1/2 = 1/10.
Note: we multiply the probabilities because the 2 events are independent.
<h3>
Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
10 + x = 62
62: Total Amount
10: The sum of 10
X: Jenny’s savings
Answer:

Step-by-step explanation:
2 × 
= 2 × 10 × 10 × 10 × 10
= 2 × 100 × 100
= 200 × 100
= 20000
And

= 2 × 2 × 2 × 2
= 4 × 4
= 16
Step-by-step explanation:
Let the equation of the line be y = mx + c
since the line is parallel to y = -1/2x + 1, the two lines have the same gradient.
therefore, m = -1/2
sub (-4, -1):
-1 = -1/2(-4) + c
c = -3
therefore equation of the line is y = -1/2x - 3
