The geometric mean of a number and four times the number is 22. What is the number?
The number, such that the geometric mean of the number and four times the number is 22, will be 11.
What is the Arithmetic and Geometric mean of two numbers a and b ?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.

Suppose that 10% of people own dogs. If you pick two people at random what is the probability that they both own a dog?
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.
What is probability?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

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.
Consider the next two days.
What is the probability it rains on both days?
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
What is the probability?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
How to calculate the probability?
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

Clarissa (the surveyor from our book) is at home and needs to figure out how tall her wall is in order to replace one of the lights. She places the mirror on the ground 27 feet from the wall. Clarissa is 9 feet from the mirror, and Clarissa's eyes are 6 feet from the ground.
Answer:
The height of the wall is 18 ft.
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:
9/6 = 27/x [where x = height of the wall]
x = 27*6/9 = 18 ft.
A spinner has three unusual sections: red, yellow, and blue.. The table shows the results of Nolan’s spins. Find the probability of landing on each color.
Answers:
Red = 1/3Yellow = 7/15Blue = 1/5====================================================
Explanation:
Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.
Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5If there are 48 double decker buses in a depot and 24 single, what percentage of the buses are single decker?
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.

A scientist is studying the relationship of two quantities S and T in an experiment. The scientist finds that
under certain conditions, as the quantity of S increases, the quantity of T decreases. After taking
measurements, the scientist determines that 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. Which of the
following is a differential equation that could describe this relationship?
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.
What is differential equation?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,
[tex]S \propto \dfrac{1}{log_e T}[/tex]
Hence the differential equation that describe the relationship between S and T is,

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
