The fewest hamsters David can have are 15

A number system is defined as a system of writing to express numbers.

Given that David has 4 cages of hamsters.

The second cage has 1/2 as many hamsters as the first.

The third cage has 1/2 as many hamsters as the second.

The fourth cage has 1/2 as many hamsters as the third.

Let the first cage has n number of hamsters

the first cage has n/2 number of hamsters

the second cage has n/4 number of hamsters

the third cage has n/8 number of hamsters

the third cage has n/16 number of hamsters

4=n+n/2+n/4+n/8+n/16

n=15

Hence, the fewest hamsters David can have are 15

Given

A rectangular park of length 60 m breadth 50 m encloses with volleyball court of length 18 m and breadth 10 m.

To find:

The area of the park excluding the court at the rate of Rs 110 per square meter.​

Solution:

Area of a rectangle is:

[tex]Area=length \times breadth[/tex]

Area of whole park is:

[tex]A_1=60 \times 50[/tex]

[tex]A_1=3000[/tex]

Area of volleyball court is:

[tex]A_2=18 \times 10[/tex]

[tex]A_2=180[/tex]

Now, the area of the park excluding the court is:

[tex]A=A_1-A_2[/tex]

[tex]A=3000-180[/tex]

[tex]A=2820[/tex]

Therefore, the area of the park excluding the court is 2820 square meter.

Answer:

0.1269 = 12.69% probability that the entire batch will be rejected.

Step-by-step explanation:

CD's are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

4500 CDs, which means that [tex]N = 5000[/tex]

150 defective, which means that [tex]k = 150[/tex]

4 are selected, which means that [tex]n = 4[/tex]

What is the probability that the entire batch will be rejected?

At least 1 defective, which is:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,4500,4,150) = \frac{C_{150,0}*C_{4350,4}}{C_{4500,4}} = 0.8731[/tex]

So

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8731 = 0.1269[/tex]

0.1269 = 12.69% probability that the entire batch will be rejected.

Answer:

It's a square with four equal sides each side is 6cm. The angles at the four edges are all same have 90° between each two sides. You can calculate the area of the four triangles by using the formula 1/2 × hight × base. The hight will be 6 divided by 2 which is equal 3cm, and the base will be 6cm. So the area of each triangle is 1/2×3×6=9cm^2.

Answer:

5sqrt2

Step-by-step explanation:

Using the pythagorean theorem, we get 5^2+5^2=c^2. C is the diagonal here. 25+25=c^2, c^2=50. c=sqrt50. Simplifying it, we get the diagonal as 5sqrt2.

Answer:

8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

This is a special right triangle with angle measures 90-60-30 degrees

The side lengths are like the following :

The side length that sees 90 degrees is represented with x

The side length that sees 60 degrees is represented with x[tex]\sqrt{3}[/tex]

The side length that sees 30 degrees is represented with 2x

the side that sees 90 degrees is given as 16 so x = 8 and so  a = 8[tex]\sqrt{3}[/tex]

x = 44.8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos 48 = 30/x

x cos 48 = 30

x = 30 / cos 48

x=44.83429

Rounding to the nearest tenth

x = 44.8

Step-by-step explanation:

5 ^ 1/3  * 25 ^ 1/3

Rewriting 25 and 5^2

5 ^ 1/3  * 5^2 ^ 1/3

We know that a^b^c = a^ (b*c)

5 ^ 1/3  * 5^ 2/3

We know a^b  * a^c = a^(b+c)

5^ ( 1/3 + 2/3)

Answer:

S.I = $1,608,000

Step-by-step explanation:

Given the following data;

To find the simple interest, we would use the formula;

S.I = PRT

Where;

Since the interest is being paid every two months (six times a year), the 4% interest will be divided by 6.

Thus: 4% every two months = [tex] 4 * \frac {2}{12} [/tex] = [tex] \frac {8}{12} [/tex]  = 0.67% = 0.0067

4 years = 4 * 6 = 24 two-month years.

Substituting the values into the formula, we have;

S.I = 10.000.000 * 0.0067 * 24

S.I = $1,608,000

Answer:

2.5%

Step-by-step explanation:

Given :

Mean, μ = 190

Standard deviation, σ = 30

Probability that more than 250 books are borrowed ;

x = 250

P(Z > z)

Z = (x - μ) / σ

P[Z > (x - μ) / σ] = P[Z > (250 - 190) / 30]

P(Z > z) = P(Z > 2)

P(Z > 2) = 1 - P(Z < 2) = 1 - 0.97725

P(Z > 2) = 1 - P(Z < 2) = 0.02275

(0.02275 * 100)% = 2.275%

2.5% is closest to 2.275%

Answer:

a) X( w ) = 1 /jw -   e^-jw / jw

b) X1(t) = 1  for  0.5  

   X1(t) = 0 for elsewhere

Step-by-step explanation:

x(t) continuous time function = 1

interval ( 0,1 )   also x(t) = 0 outside the given interval

a) Determine the continuous time Fourier transformation of x(t)

x( t ) = u(t) - u(t - 1 )

x ( w ) = 1 /jw -   e^-jw / jw

b) supposing x1(t) = x(2t)

x1(t) = u(t) - u ( t - 0.5 )

x1(t) = 1  for  0.5  

x1(t) = 0 for elsewhere

Step-by-step explanation:

The centroid divide a median in two parts, with ratio 1/3 and 2/3.

In particular the part between the centroid and the point where the median touches the side is 1/3 of the median.

We can build this proportion:

ST : 1/3 = IT : 3/3

9 : 1/3 = IT : 1

IT = 9 * 3 = 27

Answer:

Hello the answer is 5x - y = 30!

Step-by-step explanation:

m = (0 (-5))/(6 - 3) = (0 + 5)/(3) = 5/3

y = mx + b

O = (5/3)(6) + b

O = (30/3) + b

O = 10 + b

-10 = b

3y = 5x - 30

3y + 30 = 5x

5x - 3y = 30

Answer:

The base is 90 sq

Step-by-step explanation:
