Answer:
Her oldest was 9, and the other 2 were 2
Answer:
total population in the year 2000=4400
total population in the year 2010=5060
no of people increased=5060-4400
=660
increase percent=660/4400*100%
=3/20*100%
=15%
Step-by-step explanation:
15/100*5060
0.15*5060
759
in 2020 population will be
5060+759
5819
therefore the population will be 5819 in 2020
Answer:
x = 45.6°
Step-by-step explanation:
As we can see, this is a right triangle, so there are known relationships
well to start we have to know the relationship between angles, legs and the hypotenuse
α = x°
a: adjacent
o: opposite = 5
h: hypotenuse = 7
sin α = o/h
cos α = a/h
tan α = o/a
we see that it has (angle, hypotenuse, opposite)
is the sine
sin α = o/h
sin x = 5/7
x = sin^-1 (5/7)
x = 45.58°
if we want to round to the nearest tenth
x = 45.58° = 45.6°
Answer:
a) 
b) 
c) 
Step-by-step explanation:
For this case we have the following probability distribution function:
X P(X)
1 0.04
2 0.12
3 0.18
4 0.24
5 0.13
6 0.15
7 0.10
8 0.04
___________
Total 1.00
Part a
For this case we want this probability:

Part b
What is the probability that there are 5 or more members in a typical household in India? (Round your answer to 2 decimal places.)
For this case we want this probability:

Part c
What is the probability that the number of members in a typical household in India is strictly between 2 and 5? (Round your answer to 2 decimal places.)
We want this probability:
