Kelsey, a marine biologist, has determined that the population (y) of Blue Whales off the coast of Antarctica varies with time,
in months, (x). The population changes have been mapped using the graph below. What is the range of the population of Blue Whales off the coast of Antarctica from months 0 to 10?
1 answer:
Answer: The answer is (A) [0,100].
Step-by-step explanation: Given in the question that a marine biologist Kelsey determined that the population of Blue Whales off the coast of Antarctica varies with time as shown in the given graph.
The population of Blue Whales (y) is plotted on the Y-axis and the time in months (x) is plotted on the X-axis.
We need to find the range of the population of Blue Whales off the coast of Antarctica from 0 to 10 months.
We can see from the attached graph that
when x = 0, then y = 0,
when x = 10, then y = 100.
That is, when time varies between 0 to 10 months, then the population of Blue Whales varies between 0 and 100.
Thus, the correct option is (A) [0,100].

Answer:
Step-by-step explanation:
Given:
A = 96°
B = 25°
C = 59°
a = 13
Required:
b and c
SOLUTION:
Use Sine Rule to find the measure of a and b, respectively.
✍️Thus, to find b, use,
Plug in the values
Multiply both sides by sin(25)
(nearest tenth)
✍️To find c, use,
Plug in the values
Multiply both sides by sin(59)
(nearest tenth)
Answer:
0.096
Step-by-step explanation:
The bag contains 10 white , 12 blue, 13 red , 7 yellow and 8 green balls.
All the events of drawing a ball will be independent
so selecting one ball white and one red will be
using the multiplication rule of probability we get
P= P(blue)* P(white) + P(white)*P(blue)
as its said to get one blue and one white but does not specify to get which ball at which place
P=
P= = 0.096
