Answer:
The two events are not independent
Step-by-step explanation:
Two events are said to be independent only when the change in one event affect the other event.
Here the two given events are not independent.
Band weathers such as heavy rainfall, snowfall etc. leads to failure of traffic management system and thereby causes heavy traffic. This is easily seen in all major urban cities.
Hence, the two events are not independent as the traffic is affected by the weather conditions.

Ernest bought some cans of paint and 4/5 of a liter of special paint additive formulated to reduce mildew. Before painting his house, he used all of the additive to put 2/5 of a liter of additive in each can. How many cans of paint did Ernest buy?
Answer:
He bought 2 cans of paint
Step-by-step explanation:
If he put ⅖ in each, and ⅘ total, he would have had 2 cans
Quantity of special paint additive Ernest bought = [tex] \tt \frac{4}{5} \: of \: a \: litre [/tex]
Quantity of additive he put in each can = [tex] \tt \frac{2}{5} \: of \: a \: litre [/tex]
Number of cans of paint he bought :
[tex] =\tt \frac{4}{5} \div \frac{2}{5} [/tex]
[tex] = \tt\frac{4}{5} \times \frac{5}{2} [/tex]
[tex] = \tt\frac{4 \times 5}{5 \times 2} [/tex]
[tex] =\tt \frac{20}{10} [/tex]
[tex]\color{plum} = \tt2 \: paint \: cans[/tex]
▪︎Therefore, Ernest bought 2 paint cans.

What is the leading coefficient of the polynomial F(x) defined below?
Answer: 2
Step-by-step explanation:
The leading coefficient is just the value before the variable with the highest power. So first we must find the portion in your polynomial that has the highest degree. The highest degree simply means the variable with the highest power. The highest power is two, so we will look at the coefficient of that portion. The coefficient of 2x^2 is 2 .
Use binomial theorem to expand (2+X)5 in ascending powers of x up to the terms containing x3 and Use your expansion to find (1.9)5
Answer:
Diet and behavior
These awe-inspiring giants tend to be solitary animals—with the exception of females and their cubs—but at times they do congregate. Dramatic gatherings of grizzly bears can be seen at prime Alaskan fishing spots when the salmon run upstream for summer spawning. In this season, dozens of bears may gather to feast on the fish, craving fats that will sustain them through the long winter ahead.
Brown bears dig dens for winter hibernation, often holing up in a suitable-looking hillside. Females give birth during this winter rest, often to twins.
Grizzly bears are powerful, top-of-the-food-chain predators, yet much of their diet consists of nuts, berries, fruit, leaves, and roots. Bears also eat other animals, from rodents to moose.
Despite their impressive size, grizzlies have been clocked running at 30 miles an hour. They can be dangerous to humans, particularly if surprised or if humans come between a mother and her cubs.
Habitat
Grizzlies once lived in much of western North America and even roamed the Great Plains. These animals need a lot of space—their home range can encompass up to 600 square miles—so their ideal habitat is one that is isolated from development and has plenty of food and places to dig their dens.
Though European settlement gradually eliminated the bears from much of their original habitat, grizzly populations can still be found in parts of Wyoming, Montana, Idaho, and Washington State. They’re one of the most iconic residents of Yellowstone National Park. Many grizzlies also still roam the wilds of Canada and Alaska, where hunters pursue them as big game trophies.

A baker cut a pie in thirds. He cut each third into 4 equal pieces and each piece into 2 equal slices. He sold
14 slices.
What fraction of the pie did the baker sell?
The baker sold
of the pie.
Answer:
He sold 7/8 of pie.
Step-by-step explanation:
A pie cut in thirds = 3 pieces
Each of this 3 pieces is cut into 4 equal pieces, which equals
3 x 4= 12 pieces of cut pie.
Each of this piece is cut into 2 equal slices,
which equals 12 x 2= 24 slices of pie.
If he sold 14 slices, then the fraction sold is
14/24 = 7/8
He sold 7/8 of pie.

Assume that a driver faces the following loss distribution:Outcome Probability12,000 0.15 0 0.851. What is the expected loss?2. What is the standard deviation of loss?Now assume that this driver pools her losses with another driver facing the same loss distribution, and that the losses are not correlated.1. What is the expected loss for each member of the pool?2. What is the standard deviation of loss for each member of the pool?These two drivers decide to pool their losses with two other drivers with the same loss distribution, and all losses are not correlated. (This four-person group will be called Group A)1. What is the expected loss for each member of the pool?2. What is the standard deviation of loss for each member of the pool?These four drivers are considering pooling their losses with another group of four drivers (Group B) facing a different loss distribution (for each driver in the group):Outcome Probability28,000 0.0210,000 0.23 0 0.751. What is the expected loss for each member of this new pool of four drivers?2. What is the standard deviation of loss for each member of this new pool?Now, Group A and Group B decide to pool their risks, becoming a single pool of eight drivers (Group C).1. What is the expected loss for each member of this new 8-person pool of drivers?2. The standard deviation for each member of this new 8-person pool is fairly complicated to calculate. Directionally, though, how would you expect the standard deviation for the members of Group C to compare with the standard deviations of Group A and Group B (Higher/Lower/No Change). Why?If each driver were required to contribute an equal share to the Group C pool to cover losses, would the people in Group A choose to enter Group C? Would the drivers in Group B want to join the pool? Why or why not?If each driver were required to contribute an amount proportional to their own expected loss (this means that if the actual losses of Group C were equal to the Group C expected loss, then Group A drivers would contribute an amount equal to the Group A expected loss and Group B would make a contribution equal to the Group B expected loss), would the people in Group A choose to join the pool? Would the people in Group B want to join the pool? Why or why not?Finally, there is another group of four drivers (Group D) with the yet another loss distribution:Outcome Probability60,000 0.0125,000 0.1010,000 0.300 0.591. What is the expected loss for each member of Group D?2. What is the standard deviation for each member of Group D?3. Under what conditions, if any, would the Group A drivers be willing to pool with the members of Group D to become a single pool of eight drivers?
Answer:
- 1800 ; 4284.8579 ;
Step-by-step explanation:
Given the table :
Outcome _____ probability
-12000 ________ 0.15
__ 0 __________ 0.85
Expected loss, m: Σx*p(x)
(-12000 * 0.15) + (0 * 0.85)
-1800 + 0 = - 1800
Standard deviation = sqrt(Var(x))
Var(x) = Σx²*p(x) - m²
(-12000^2 * 0.15) + (0^2 * 0.85)] - 1800^2
21,600,000 - 3240000
= 18360000
Standard deviation = sqrt(18360000)
Standard deviation = 4284.8579

Answer:
v=16
Step-by-step explanation:
Multiply 8 on both sides
8* v/8= 8*2
8*8 cancels out because you reduce the numbers with the greatest common factor which is 8*8 the GCF of 8*8 is 8.
Multiply 8*2 which is 16
v=16
Answer:
C: 16.
Step-by-step explanation:
8 x 2 = 16. Therfore C is correct
