C-Child ticket

4C-Adult tickets

6.10C+9.90(4C)=1188.20

6.10C+39.60C=1188.20

45.70C=1188.20

Divide both sides by 45.70 to get C.

C=26

This means 26 child tickets were sold that day.

Let's check our answer:

26×6.10=158.60

26×4=104 (Adult tickets)

104×9.90=1029.60

158.60+1029.60=1188.20

Therefore, 26 child tickets were sold on Friday.

Simple interest is the interest calculated on the principal at a given rate for a time period.

The equation used to solve for the rate of interest r is r = (A/P - 1) / t.

It is the interest calculated on the principal at a given rate for a time period.

We have,

A = P + Prt ______(1)

A = amount

P = principal

r = rate

t = time in years

To find the rate of interest we will have to solve (1).

A = P + Prt

A = P (1 + rt)

A/P = 1 + rt

Subtract 1 on both sides.

A/P - 1 = rt

Divide t on both sides.

(A/P - 1) / t = r

r = (A/P - 1) / t

Thus,

The equation used to solve for the rate of interest r is r = (A/P - 1) / t.

Slip system can be used to give more than fair chances of selection where the number of slips for one is more than the other.

There are multiple ways of selecting random sample like tossing a coin, flipping a die, lottery system.

Describing a method which can be used to provide more than a fair chance of selection is as follows:

Julie has 3 friends, so make the total number of slips say n

where n is not a multiple of 3.  

If n is not a multiple of 3 then her 3 friends will not get an equal chance of being selected.

Consider n=5

She has 3 friends, so 2 slips has repeated names, thus creating more chance of being selected than the one who has name only on one slip.

Thus, this method may result in more chance of selection of one over other.

Answer:

The answer is C

Step-by-step explanation:

Just calculate it

The measures of angles A and B must be complementary (add up to 90°) and differ by 90°If sin A = cos B, then we can use the trigonometric identity sin A = cos (90° - A) to get:

sin A = cos B

sin A = sin (90° - B)

Setting the two expressions for sin A equal to each other, we have:

cos B = sin (90° - B)

Using the trigonometric identity sin (90° - x) = cos x, we can write:

cos B = cos (90° - B)

This means that either:

B = 90° - A

or

B = A + 90°

In other words, the measures of angles A and B must be complementary (add up to 90°) and differ by 90°.

Multistage sampling is a probability sampling technique that involves sampling in stages or multiple steps. In this technique, a large population is divided into smaller subgroups, and then a random sample is selected from each subgroup.

Here is an example of multistage sampling:

Suppose we want to conduct a study on the prevalence of a certain disease among high school students in a particular country. The population of high school students in the country is very large, so it is not feasible to sample all of them. Instead, we can use multistage sampling to select a representative sample.

In the first stage, we randomly select a certain number of schools from different regions of the country. Let's say we select 20 schools.

In the second stage, we randomly select a certain number of classes from each of the selected schools. Let's say we select 2 classes from each of the 20 schools, resulting in a total of 40 classes.

In the third stage, we randomly select a certain number of students from each of the selected classes. Let's say we select 10 students from each of the 40 classes, resulting in a total of 400 students.

This process of selecting a sample in stages is an example of multistage sampling. By selecting schools, classes, and students in a random and systematic way, we can obtain a representative sample of high school students in the country, which can be used to estimate the prevalence of the disease.

Answer: Ramesh has 80,000 100Rs, 120,000 50Rs and 200,000 10Rs.

Step-by-step explanation:

From the question, the ratio of number of 100, 50 and 10Rs notes is 2:3:5respectively and the total cash with ramesh is 400000.

Total ratio = 2+3+5 = 10

100Rs = 2/10 × 400000

= 80,000

50Rs = 3/10 × 400000

= 120,000

10Rs = 5/10 × 400000

= 200,000

Ramesh has 80,000 100Rs, 120,000 50Rs and 200,000 10Rs.

The correct answer is 5/2. The median trapezoid is the line segment that bisects the area of the trapezoid and has its end points on the 2 bases of the trapezoid.

The median length is √( (3/2)^2 + (4/2)^2 ) = √(9/4 + 16/4) = √(25/4) = 5/2. So, the length of the median of the trapezoid is 5/2.

Since the diagonals of a median trapezoid bisect each other, the median of the trapezoid is the line segment that connects the midpoints of the diagonals. To find the median length, we can use the distance formula, which is the square root of the sum of the squares of the differences in the x-coordinates and y-coordinates of the 2 points. In this case, the median length is the square root of the sum of the squares of 1/2 length of the diagonals.

The length of the median of the trapezoid will be 5/2 units.

Given that the median trapezoid is the line segment that divides the trapezoid's area and has its ends on its two bases,

The median length will be:

√( (3/2)^2 + (4/2)^2 )

= √(9/4 + 16/4)

= √(25/4)

= 5/ units

So, the length of the median of the trapezoid is 5/2.

The median of a median trapezoid is the line segment that links the midpoints of the diagonals since the diagonals of a median trapezoid bisect one another. We may use the distance formula, which is the square root of the sum of the squares of the differences in the x-coordinates and y-coordinates of the two points, to get the length of the median. The median length in this instance is equal to the square root of the sum of the squares of the diagonals' half-lengths.

Answer: for this problem. What we're going to do essentially, this is an exercise of using the formula for finding the derivative of the inverse of a function. So we have the derivative of the inverse of F would be equal to one over the derivative of F. So F prime evaluated at f inverse of X. So in this case we have X equals three. So F inverse of three, prime will be equal to one over F prime evaluated at f inverse of three. Now, looking at the table of values that you have, well, F inverse of three is going to be the X value such that X equals, or the the X values such that F equals three. So we can see that F equals three when X equals negative one. So we have one over F prime evaluated at negative one and F prime of negative one, we can see it is equal to one. So we'd have won over one or just one is the final answer.
