Answer:
The correct option is A. 14%
Step-by-step explanation:
There is a 70% chance of rain tomorrow
⇒ The probability that it will rain tomorrow = 0.7
There is a 20% chance that the volleyball game will be postponed
⇒ The probability that the volleyball game will be postponed = 0.2
Now, We need to find the probability that it will rain tomorrow and the volleyball game will be postponed
⇒ The probability that it will rain tomorrow and the volleyball game will be postponed = Probability that it will rain × Probability that the volleyball game will be postponed
⇒ The probability that it will rain tomorrow and the volleyball game will be postponed = 0.7 × 0.2
⇒ The probability that it will rain tomorrow and the volleyball game will be postponed = 0.14
⇒ The probability that it will rain tomorrow and the volleyball game will be postponed = 0.14 × 100
⇒ The probability that it will rain tomorrow and the volleyball game will be postponed = 14%
Thus, the correct option is A. 14%
Answer:
<u>Option A. about 1 seconds</u>
Step-by-step explanation:
Let the initial speed u and the final speed v
Time t , distance s and acceleration of gravity g
The equation of motion are:
v = u + gt ⇒(1)
s = ut + 0.5 gt² ⇒(2)
v² = u² + 2gs ⇒(3)
Marques drops a plate from a height of 5 feet.
So, u = 0 , s = 5 ft , g = 9.8 m/sec²
Substitute at (2)
s = ut + 0.5 gt²
5 = 0 * t + 0.5 * 10 * t²
∴ t² = 5/(0.5*9.8) = 1.02
∴ t = √1.02 = 1.01 seconds ≈ 1 seconds (to the nearest integer)
<u>The answer is option A. about 1 seconds</u>
Answer:
Ratio scales
If the scale of the plan is 1 : 100 this means the real measurements are 100 times longer than they are on the plan
