Answer:

Yes ,it represents a binomial experiment.

Step-by-step explanation:

In order for a probability experiment to represent a binomial experiment ,there are three conditions.

1) There should be a fixed number of trials.

2) Trials should be independent.

3)Each trial can result in two outcomes.

In this experiment ,there is a fixed number of trial ,since it is administered to 180180 individuals.

Outcome on an individual does not affect the outcome of others.

Individuals respond as favorably or not ,so it can be reduced to two outcomes.

All conditions are met, so it can be considered as binomial experiment.

Write each sum using summation notation<br> 12 + 22 + 32 + 42 + ⋯ + 10000^2
Murljashka [212]

Answer:

50,00,70,000

Step-by-step explanation:

The given sequence is Arithmetic Progression.

Arithmetic Progression is a sequence in which every two neighbor digits have equal distances.

Here first we will find the number of terms

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

Now, In given sequence: 12, 22, 32, 42, ⋯ , 100002

a = 12, d = 10, n = ? and  aₙ= 100002

∴ 100002  = 12 + (n - 1) × (10)

⇒ 99990 = 10(n - 1)

⇒ n = 10000

Now using the formula of Sum of Arithmetic Sequence,

Sₙ = n÷2[2a + (n - 1)d]

⇒ Sₙ = (10000÷2)[2 × 12 + 9999 × 10]

⇒ Sₙ = 5000 [ 24 + 99990]

⇒ Sₙ = 5000 × 100014 = 50,00,70,000

It is estimated that the population of the world is increasing at an average rate of 1.09%. The population was about 7,632,819,3
morpeh [17]

Answer:

The equation that represents the population after T years is

P_{t}  = 7,632,819,325 [1 +\frac{1.09}{100} ]^{T}

Step-by-step explanation:

Population in the year 2018 ( P )= 7,632,819,325

Rate of increase R = 1.09 %

The population after T years is given by the formula

P_{t}  = P [1 +\frac{R}{100} ]^{T} -------- (1)

Where P = population in 2018

R = rate of increase

T = time  period

Put the values of P & R in above equation we get

P_{t}  = 7,632,819,325 [1 +\frac{1.09}{100} ]^{T}

This is the equation that represents the population after T years.

What is the solution to the system of equations 2x-y=7 and y=2x+3
Yuri [45]
Make y the subject in both equations

2x-y=7

-y=-2x+7

y=2x-7

For the second equation

y=2x+3

The two equations are parallel because they have the same gradient or slope but different y intercepts.

This type of equations have no solution because they will never intersect.

NO SOLUTION

The correct answer is C
