A frog makes jumps, each exactly meter long. The directions of the jumps are chosen independently at random. What is the probability that the frog's final position is no more than meter from its starting position

Answers

Answer 1

Answer:

1 by 4

Step-by-step explanation:

The computation of the probability is as follows

Here we assume the moves in a complex numbers i.e. a, b and c

Now the frog begins with the starting point.

So it would become easy to represent the exactly one element in a set that has lower or equal than 1

|a + b + c| , |a + b - c|, |a - b + c|, |a - b- c|

So here the probability is 1 by 4

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

The amount Liam got on his 18th birthday is $34,251.05.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

Example:

P = 200

R = 2%

t = 3 years

compounded annually, n =1

A = $212.24

We have,

Principal = $20,000

Rate = 3%

There are 4 quarters in a year.

It is compounded quarterly.

This means,

n = 4

t = 18 years

The amount compounded quarterly.

A = 20,000 [tex](1 + 0.0075)^{72}[/tex]

A = 20,000 x [tex]1.0075^{72}[/tex]

A = $34,251.05

Thus,

The amount Liam got on his 18th birthday is $34,251.05.

Answer:

The linear equations which have one solution are C. [tex]4\cdot (-6) +4 = 2\cdot (r-3)[/tex], D. [tex]2\cdot (-4) = 5\cdot (r-3) +3[/tex] and E. [tex](20-1) +3\cdot r = 5\cdot (r-2) + 3[/tex].

What are the assumptions that we should check before conducting the hypothesis test?

Answers

Answer:

Assumptions before conduction hypothesis test are mentioned below in the explanation.

Step-by-step explanation:

As this question is incomplete, and I will try my best to answer this question.

We are asked in this question to write the assumptions that  we check before conducting the hypothesis test.

Solution:

Assumptions of hypothesis test:

1. We have to make assumption that all the observations are independent.

2. Secondly, we need to take assumption that, all the parent population of the data reflects normal distribution.

3. Furthermore, we need to assume that experimental error or random error is independently identical and normally distributed with mean "0" and variance of (σ^2).

Above are the assumptions that we should check before conducting hypothesis test.

Answer:

mass = 42 kg

Step-by-step explanation:

We know that we have the formula that

W = m * g

Then

given

weight (w) = 420

g = 10 m/s²

then

W = m* g

420 = m * 10

m = 420/10

m = 42 kg

Hope it helps :)

Answer:

Step-by-step explanation: weight = 420N

                                             mass= ?

                                    we know,

                                             weight = mass . acceleration due to gravity

                                             or,  420  = mass . 9.8
