Answer: probability 0.01 %

Step-by-step explanation:

P(A) = 10% = 10/100 = 0.10

pick two people -

= P(A).P(A)

= 0.10 times 0.10

= 0.01

probability = 0.01

The probability that they both own a dog is 1/50 or 0.02.

Probability is the chance of happening an event or incident.

Given, 10% of people own dogs.

Let, there are 100 people.

Therefore, the number of people own dogs is

= 100 × 10%

= 10

If I pick two people at random, then the probability that they both own a dog is

= 2/100

= 1/50

= 0.02

Answer:

x² + y² = 6

Step-by-step explanation:

The standard form of the equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Here r = [tex]\sqrt{6}[/tex] , then

x² + y² = ([tex]\sqrt{6}[/tex] )² , that is

x² + y² = 6

The number, such that the geometric mean of the number and four times the number is 22, will be 11.

The arithmetic mean of two numbers [a] and [b] is equal to (a + b)/2  and their geometric mean is equal to  [tex]\sqrt{ab}[/tex]

We have the geometric mean of a number and four times the number is 22.

According to the question, we can write -

G.M. = [tex]\sqrt{ab}[/tex]

Assume that the number is [x]. Then the second number will be [4x]. So -

22 = √4x²

22 = √(2x)²

2x = 22

x = 11

Therefore, the number, such that the geometric mean of the number and four times the number is 22, will be 11.

=> y = √(x + 36)

Answer:

17.28

Step-by-step explanation:

Totall buses: 48+28 = 72

% Of single decker: 72×(24÷100) = 17.28

Approximately 33.33 percentage of the buses in the depot are single-decker buses.

To find the percentage of single-decker buses, we need to calculate the ratio of the number of single-decker buses to the total number of buses (single-decker and double-decker) and then multiply by 100.

The total number of buses in the depot is given as 48 double-decker buses + 24 single-decker buses = 72 buses.

The number of single-decker buses is 24.

The ratio of single-decker buses to the total number of buses is 24 buses / 72 buses = 1/3.

To find the percentage, we multiply the ratio by 100:

(1/3) * 100 = 33.33%

Therefore, approximately 33.33% of the buses in the depot are single-decker buses.

Differential equation is a way to represents the function and its variable by relating them.Hence the differential equation that describe the relationship between S and T is,

[tex]S \propto \dfrac{1}{log_e T}[/tex]

Given-

The quantity of S increases, the quantity of T decreases.

The rate of change of the quantity of S with respect to the  quantity of T present is inversely proportional to the natural logarithm of the quantity of T.

Differential equation is a way to represents the function and its variable by relating them.

As the quantity of S changes with respect to the  quantity of T present is inversely proportional. Thus,

[tex]S \propto \dfrac{1}{T}[/tex]

But quantity of S changes inversely proportional to the natural logarithm of the quantity of T. The natural logarithm of a  number is its logarithm to the base of e (constant).

Thus the equation can be given is,

Step-by-step explanation:

I have taken a look at the question, and will label the diagram accordingly. Check the attachment.

We are asked to calculate the height of the wall. Well, the incidence ray is equal to the reflected ray, so therefore by AA we have similar triangles. Setting up a proportion to determine the height of the wall:

Answer:

1.)

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

Conditional probability ;

0.47

Step-by-step explanation:

Let :

E = Excellent ; A = Average ; N = not up to standard

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.

The probability that Leo is coming :

Leo ; Excellent = 0.7

Leo ; Average = 0.3

Leo; Not up to standard = 0.2

Hence, probability they Leo is coming :

(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)

0.35 + 0.06 + 0.06

= 0.47

Answer:

  (x +10)(x -4)

Step-by-step explanation:

Compare the factored and expanded forms:

  (x +p)(x +q) = x^2 +(p+q)x +pq = x^2 +6x -40

That is, the constants in the binomial factors will be factors of -40 that have a sum of 6. This is where your knowledge of multiplication tables is helpful.

  -40 = -1×40 = -2×20 = -4×10 = -5×8

The sums of these factor pairs are 39, 18, 6, 3, respectively. So, the one we want is (-4)(10) = -40. Now that we know the values of 'p' and 'q', we can write the factorization ...

  x^2 +6x -40 = (x -4)(x +10)

Answer:

Day 1=0.075

Day 2=0.0375

Step-by-step explanation:

Divide each day by 2

The probability it rains on both days if the probability that it rains in London on any particular day is 0.3 is 0.595

The probability is the likeliness of happening an event. It can be calculated by using the following formula:

Probability=Number of events/Number of total outcomes

The probability that it rains in London on any particular day is 0.3

If it rains then the probability of it raining the following day decreases to 0.15.

The probability that it rains on the second day=1-0.15=0.85

The probability that it rains on the third day=0.85-0.15=0.7

The probability that it rains on both is=0.85*0.7=0.595

Hence the probability that it rains on both is 0.595
