Step-by-step explanation:
area including track=area of 2 semi circles+area of rectangle
=2×1/2×π×46²+86×65
=2116 π+5590
area of grass=2×1/2×π×40²+80×65=1600π+5200
≈10226.55 m²
area of track=2116π+5590-1600π-5200
=516π+390
≈2011.06 m²
Answer:
Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
= 
- 
← subtract numerators leaving the common denominator
= 
= 
= 
← cancel common factor (y - 1) on numerator/denominator
=
Probability of getting an order from Restaurant A or an order that is accurate is 1.21,
The events are not disjoint events.
<h3>
What is the probability?</h3>
Probability is used to calculate the odds that a random event would occur. The odds that the random event happens lie between 0 and 1.
Total number of accurate orders = 332 + 277 + 244 + 150 = 1,003
Total number of orders = 31 + 51 + 30 + 10 + 1003 = 1,125
Total number of orders from restaurant A = 332 + 31 = 363
Probability of getting an order from Restaurant A = total number of orders from restaurant A / total number of orders
363 / 1125 = 0.32
Probability that the order is accurate = number of accurate orders / total number of orders
1003 / 1125 = 0.89
Probability of getting an order from Restaurant A or an order that is accurate = 0.32 + 0.89 = 1.21
Disjoint events are events that are mutually exclusive. If one event happens, the other event cannot happen
