A population of insects grows exponentially, as shown in the table. Suppose the increase in population continues at the same rate.
from the given table
when x=0 , y=20
when x= 1 , y = 30
We use this information to find exponential growth equation
General form of exponential growth is
WE plug in the given values and find out value of a and b
when x=0 , y=20
20 = a
Now we find out b
when x= 1 , y = 30
divide both sides by 20
So exponential function becomes
Now we find the insect population at the end of week 11
We plug in 11 for x
Round the answer to nearest whole number
1730 is the insect population at the end of week 11
First, find the area of the larger sector (the 360-130=230 degree sector), then add the area of the triangle.
area of the larger sector:(230/360)π*11.1²≈247.17
area of the triangle when two sides and the angle between the two sides are given: (absinФ)/2. In this case, a=11.1, b=11.1, Ф=130
(11.1*11.1*sin130)/2≈47.19
the total area is 247.17+47.19≈294.4

Answer:
a)- Given that a student is a 10th grader, there is a 14% chance he or she has a job.
Step-by-step explanation:
Option (a) is correct here because Relative frequency means the probability of occurrence or number of time-specific event occurs to the total event.
Option (b) is not correct because We already know that student is in 10th or 11th grade, after that we get to know about 14% chance.
Option (c) & (d) are clearly not possible.
Answer:
false
Step-by-step explanation:
correct me if this is wrong, but it's actually x>1
Answer: 7(-4-x) —> -28-7x. 7(4+x) —> 28+7x. -7(-4+x) —> 28-7x. -7(4-x) —> -28+7x
