In a city with a population of 1 million, 500 people have been diagnosed with cancer, whereas the rest of the people do not have
Leni [432]

Class distribution is considered to be normal using normal approximation to binomial.

A frequency distribution is a table that shows classes or intervals of data with a count of the number in each class.

Given :

In a city with a population of 1 million

i.e Population size (N) = 1 million = 1000000

From which 500 people have been diagnosed with cancer

Let X : No. of people  have been diagnosed with cancer

X = 500

Population proportion (p) :

p = XNp =5001000000p = 0.0005

So , the proportion of people who do not have cancer (q)=1-p

                                                                                               =1-0.0005

                                                                                               =0.9995

Here the distribution of X is Binomial

Such that :

i. No. of trials are fixed

ii. Probability of success is constant (p=0.0005)

iii. Possible outcomes are two (having cancer or not)

Here we can use normal approximation to Binomial

Because N is very large

So  class distribution is considered to be normal using normal approximation to binomial.

A + B= 180°

(5x+20)+(9x-92)=180°

14x-72=180°

14x=252

x=18

A=5(18)+20

A=110

A principal of 750$ is invested in an account at 9% per year simple interest. What is the account total after 5 years
balandron [24]
Hi there
The formula of the future value of simple interest is
A=p (1+rt)
A future value?
P principle 750
R interest rate 0.09
T time 5years
So
A=750×(1+0.09×5)
A=1,087.5

Good luck!

Answer:

Corresponding angles theorem.

Step-by-step explanation:

The corresponding angles theorem states that corresponding angles are congruent.

Pretty much means that every other angle is congruent if two lines are parallel and a line traverses them.
