Answer:
6m/s
Explanation:
Given the information :
an object travels 16 metre in 4 seconds and then another 16 metre in 2second.
what is the average speed of the object?
First portion of travel:
Distance = 16 meters
Time = 4 seconds
Second portion:
Distance = 16 meters
Time = 2 seconds
Speed is calculated as the proportion of distance traveled to the time taken.
Speed = distance / time
First portion :
Speed attained
Distance / time = speed
16 meters / 4 seconds = 4m/s
Second portion:
Speed attained
Distance / time = speed
16 meters / 2 seconds = 8m/s
Average speed :
(first portion + second portion) / 2
(4m/s + 8m/s) / 2
12m/s ÷ 2
= 6m/s

Answer:
Increase aggregate demand.
Explanation:
A fiscal policy that is designed to slow the rate of economic growth will, ceteris paribus increase aggregate demand. This policy is also known as the contractionary policy.
The basic function of this policy is to slow the economic growth and basically try to flatten out the rate of inflation. It also effects the aggregate demand, the graph of which shifts to the right, meaning triggering an increase. This is done because the long term effects of inflation can effect the standard of living as recession would.
Answer:
1. 0.06
2. 0.38
3. 0.52
4. 0.06
Explanation:
1) Both decline = P1(D) × P2(D)
= 0.2 × 0.3
= 0.06
(stock 1 declines and stock 2 declines)
2) Exactly one rises:
= P1(R) × [P2(U) + P2(D)] + P2(R) × [P1(U) + P1(D)]
= 0.2 × [0.4+ 0.3] + 0.3 × [0.6 + 0.2]
= 0.14 + 0.24
= 0.38
(stock 1 rises and {stock 2 declines or remains unchanged})
or (stock 2 rises and {stock 1 declines or remains unchanged})
3) Exactly one unchanged:
= P1(U) × [P2(R) + P2(D)] + P2(U) × [P1(R) + P1(D)]
= 0.6 × [0.3 + 0.3] + 0.4 × [0.2 + 0.2]
= 0.36 + 0.16
= 0.52
4) Both rise = P1(R) × P2(R)
= 0.2 × 0.3
= 0.06
Even though stocks, securities, and mutual funds are higher-risk investments, many people invest in them because they give higher rate of return.
<span>The rate of return are higher on high risk investments compared with low risk investments. This is because high risk investment have a big possibility of incurring losses, however, if said investment venture is successful and it generates a huge profit, its return is also bigger than when you invest in low risk investments.</span>
