The codes of the countries are 34, 35 and 36
How to determine the codes of the countries?The given parameters are
Sum of codes = 105
Where the numbers are consecutive numbers
This means that
B = A + 1
C = A + 2
So, we have
A +A + 1 + A + 2 = 105
Evaluate the like terms
3A = 102
Divide through by 3
A = 34
So, we have
B = A + 1 = 34 + 1 = 35
C = A + 2 = 34 + 2 = 36
Hence, the codes of the countries are 34, 35 and 36

What is a decimal number?A decimal number is a number that consists of a whole number and a fractional part separated by a point. For example – 3.5, 6.79, 78.32, etc.
Given here: Given the proper fraction as 1/4
To convert a fraction to a decimal, we'll just divide the numerator...by the denominator.
Thus 1/4=0.25
1/2=0.5
Now the difference between each of the given points is 1/2-1/4=0.25
And 1/4-0=0.25
Also 1-1/4=0.75
Thus the point 1/4 is equidistant from the points 0 and 1/2 but is 0.75 units away from 1
Hence, The given point 1/4 lie closer to 0& 1/2 than 1

2.5+x =81−8.1 find x
Answer:
\( \sf \: x = 70.4\)
Step-by-step explanation:
Given equation,
→ 2.5 + x = 81 - 8.1
Now the value of x will be,
→ 2.5 + x = 81 - 8.1
→ 2.5 + x = 72.9
→ x = 72.9 - 2.5
→ [ x = 70.4 ]
Hence, value of x is 70.4.

in the inspection of tin plate by continous electrolytic process, .15 imperfections are spotted on one minute average. find the probability that three imperfection plates are spottwd in three minutes
The probability of spotting 3 imperfections plates in 3 minutes is .3352.
The probability of spotting 3 imperfections plates in 3 minutes can be calculated using the binomial probability formula. This formula is used to calculate the probability of getting a certain number of successes in a certain number of trials (n), given a certain probability of success (p) for each trial.
In this case, the probability of success (p) is .15 and the number of trials (n) is 3. The formula for this is:
\(P(X = 3) = 3C3(.15)^3(1-.15)^(3-3)\)
P(X = 3) = .3352
Therefore, the probability of spotting 3 imperfections plates in 3 minutes is .3352.

A circle has a circumference of 38 meters. what is the radius of the circle (in meters)? round your answer to two decimal places. include the units in the answer.
The final answer is: 6.09 meters.
The circumference of a circle is given by the formula C = 2πr, where C is the circumference, r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14.
To find the radius of a circle given its circumference, you can use the formula: r = C / 2π
Plugging in the values given in the problem, we get: r = 38 meters / 2π
Then we will get r= 38/2(22/7)
Therefore, the radius of the circle is approximately 6.09 meters. Rounded to two decimal places, the radius is 6.09 meters.

Find the lateral surface area of a regular pyramid with a triangular base if each edge of the base measures 8
inches and the slant height is 5 inches.
In this case, the base of the pyramid is a triangle with each edge measuring 8 inches, and the slant height is 5 inches.
The lateral surface area of a regular pyramid with a triangular base can be found using the formula: LSA = (1/2) * perimeter of base * slant height.
To find the perimeter of the base, we multiply the length of one edge by the number of edges in the base. Since the base is a triangle, it has 3 edges. Therefore, the perimeter of the base is 3 * 8 = 24 inches.
Using the formula for the lateral surface area, we have LSA = (1/2) * 24 * 5 = 60 square inches.
Hence, the lateral surface area of the regular pyramid with a triangular base, given the edge length of 8 inches and a slant height of 5 inches, is 60 square inches.

A cotton candy vendor has 27 cones of blue cotton candy to sell. If the blue cotton candy is 75% of the total number of cones, how many total cotton candy cones does he have?
Answer:
36
Step-by-step explanation:
Let the total number of cotton candy = A
Number of blue cotton candy = 27 cones
Percentage of blue cotton candy = 75%
Therefore, the total number of cotton candy is calculated as:
27/A × 100 = 75%
2700/A = 75
Cross Multiply
75A = 2700
A = 2700/75
A = 36
Therefore, the amount of total cotton candy that we have is 36.

Answer:
Larger number = 16
Step-by-step explanation:
Forming the equation,
→ x + (x + 1) + (x + 2) = 45
→ 3x + 3 = 45
Now the value of x will be,
→ 3x + 3 = 45
→ 3x = 45 - 3
→ x = 42/3
→ [ x = 14 ]
The value of larger number is,
→ x + 2
→ 14 + 2 = 16
Hence, larger number is 16.

suppose that the ages of medical residents are normally distributed with a mean of 27 years and standard deviation 2 years. what percent of medical residents are less than 28 years old?
The percent of medical residents less than 28 years old is 69.15%.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value = 28
μ = mean = 27
σ = standard deviation = 2
z-score = (28 - 27) / 2
z-score = (1) / 2
z-score = 0.5
Find the probability that corresponds to the z-score in the z-table. (see attached images)
at z = 0.5, p = 0.6915
Multiply the probability by 100 to get the percentage.
% = p x 100
% = 0.6915 x 100
% = 69.15
Hence, the percent of medical residents that are less than 28 years old is 69.15%.

How to Find the Area of Similar Figures?Where A and B represent the areas of two similar figures, and a and b are their corresponding side lengths, respectively, the formula that relates their areas and side lengths is:
Area of figure A / Area of figure B = a²/b².
Given that the two figures are similar as shown in the image above, find each of their respective side lengths if we are given the following:
Perimeter of smaller figure = 20 m
Area of smaller figure = 19.6 m²

Sia sells large candles for $3 each and small candles for $2 each. she sold 17 candles for $46.00 How many of each size candle did she sell?
Answer:
The number of large size candles sells are 12 and the number of small size candles are 5 .
Step-by-step explanation:
As given
Sia sells large candles for $3 each and small candles for $2 each.
She sold 17 candles for $46.00.
Let us assume that the large size candle sells are x .
Let us assume that the small size candle sells are y.
Equation becomes
x + y = 17
3x + 2y = 46
Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .
3x - 3x + 2y - 3y = 46 - 51
-y = - 5
y = 5
Put in the equation x + y = 17 .
x + 5 = 17
x = 17 - 5
x = 12
Therefore the number of large size candles sells are 12 and the number of small size candles are 5 .

The common characteristics shared by functions are the domain and the y-intercept. Option B and Option E
The two characteristics that functions have in common are:
B) Domain: The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. It represents the values for which the function has a corresponding output.
OE) Y-intercept: The y-intercept of a function is the point where the graph of the function intersects the y-axis. It represents the value of the function when x = 0. The y-intercept is a constant value for a given function and is shared by all points on the graph with the same y-coordinate.
A) Range: The range of a function refers to the set of all possible output values (y-values) that the function can produce. It represents the values that the function can take on as its output. The range can vary depending on the type of function and any restrictions or limitations on the output values.
C) Minimum: The minimum of a function refers to the lowest value that the function can attain within a given interval. It represents the point(s) on the graph where the function reaches its lowest value. However, not all functions have a minimum, as some may have a maximum or no extreme points at all.
OD) X-intercept: The x-intercept of a function is the point(s) where the graph of the function intersects the x-axis. It represents the value(s) of the input variable (x) for which the function output (y) is equal to zero. While many functions have x-intercepts, not all functions necessarily have them.
