Based on the given equation condition, the number of children is 182, the number of students is 94 and the number of adults is 91 respectively.

What is an equation?

A statement that affirms the equivalence of two expressions joined by the equals symbol "=" is known as an equation. The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign.

Let c represent the number of children, s represent the number of students and a represents the number of adults. Then,

According to the question,

or, c+s+a = 367 ....................(i)

or, a=c/2 .................. (ii)

or, 5c+7s+12a = 2660 ................ (iii)

Multiply equation (i) with 5, then

7c+7s+7a = 7(367)= 2569......... (iv)

subtract (iv) from (iii), we get

-2c +5a = 2660-2569 = 91

From (ii), -2c +5(c/2) = 91

or, 0.5c = 91

or, c = 182

Then, a = 182/2 = 91

And, s = 367-c-a = 367-182-91 = 94

Hence, the number of children is 182, the number of students is 94 and the number of adults is 91 respectively.

The condition that is it preferable to use stratified random sampling rather than simple random sampling is C. The population can be divided into a large number of strata so that each stratum contains only a few individuals

Stratified sampling is a method of sampling from a population that can be divided into subpopulations in statistics. When sampling subpopulations within an overall population in statistical surveys, it may be advantageous to sample each subpopulation independently.

Stratified random sampling is a sampling method that divides a population into smaller subgroups known as strata. Strata are formed in stratified random sampling, or stratification, based on members' shared attributes or characteristics, such as income or educational attainment.

Answer:

y = 10 + 5x

Step-by-step explanation:

We are told he travelled 10 km away from the city by bus.

Now, after that he walked by foot in the same direction at the speed of 5 km/h.

Now, distance = speed x time

In x hours, distance he will have walked by foot = 5x

Which means total distance he has covered both by bus and walking by foot = 10 + 5x

We are told y is the distance from the city after x hours of walking.

Thus;. y = 10 + 5x

Number of pounds of banana sold is, 14

And, Number of pounds of grapes sold is, 36

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Each pound of banana sell for $2.

And, Each pound of grapes sell for $1.

Now, Let number of pounds of sell banana = x

And, Number of pounds of sell grapes = y

Since, There are 50 pounds of fruits are sell.

So, We can formulate;

⇒ x + y = 50   .. (i)

And, Each pound of banana sell for $2.

And, Each pound of grapes sell for $1.

Hence, We get;

⇒ $2x + $1y = $64

⇒ 2x + y = 64  .. (ii)

Substitute value of y from (i) in (ii), we get;

⇒ 2x + y = 64

⇒ 2x + (50 - x) = 64

⇒ 2x + 50 - x = 64

⇒ x = 64 - 50

⇒ x = 14

And, From (i);

⇒ x + y = 50

⇒ 14 + y = 50

⇒ y = 50 - 14

⇒ y = 36

So, Number of pounds of sell banana = 14 pounds

And, Number of pounds of sell grapes = 36 pounds

The tuxedo was rented for 4 days.

Let's start by assigning variables to the unknowns. Let "x" be the number of additional days rented, and "d" be the total number of days rented (including the first day).

From the given information, we know that the flat fee for the rental is $150, so the cost of the additional days is the total cost minus the flat fee, which is $300 - $150 = $150. We also know that the cost for each additional day is $50. Therefore, we can set up the equation:

$150 + $50x = $300

Subtracting $150 from both sides, we get:

$50x = $150

Dividing both sides by $50, we get:

x = 3

So the tuxedo was rented for 3 additional days, making the total number of days rented:

Answer:

srry but search 12 z6xs

Step-by-step explanation:

(a) The total interest that Ravi will have to pay is $120.  (b) The total repayment amount will be $920.

a) The interest rate is 5% per year, so Ravi will pay 5% * 800 = $40 per year in interest.

Since he borrowed the money for 3 years, he will pay a total of 3 * 40 = $120 in interest.

b) The total repayment amount will be the principal amount of $800 plus the interest of $120, for a total of 800 + 120 = $920.

Simple interest formula: I = P * r * t

Where:

I is the interest

P is the principal amount

r is the interest rate

t is the time in years

Interest per year: 5% * 800 = $40

Total interest: 3 * 40 = $120

Total repayment amount: 800 + 120 = $920

The given data is represented in the attachment.

a) Explain why yields from one type of corn are not independent of the yields from the other type of corn.

Yields from one type of corn are not independent of the yields from the other type of corn because, as the corns are planted in two similar plots, they could compete during watering process, even the amount of nutrients shared and the type of air. This means one corn may get more nutrients than the other. Therefore, they are not independent (they are dependent).

b) Based on the summary statistics, GM is expected to more likely obtain yield greater than 123, because 123 is greater than mean for regular corn but less than mean for GM corn.

Thus,

P(yield>123|GM)>0.5; and P(yield>123|Regular)<0.5

The mass of one kitten is 1.8 Kg

Mean, median, and mode are the measures of central tendency, used to study the various characteristics of a given set of data. A measure of central tendency describes a set of data by identifying the central position in the data set as a single value. We can think of it as a tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendencies are Mean, Median, and Mode. Choosing the best measure of central tendency depends on the type of data we have.

The arithmetic mean of a given data is the sum of all observations divided by the number of observations. For example, a cricketer's scores in five matches are as follows: 12, 34, 45, 50, 24. To find his average score in a match, we calculate the arithmetic mean of data using the mean formula:

Mean = Sum of all observations/Number of observations

Mean = (12 + 34 + 45 + 50 + 24)/5

Mean = 165/5 = 33

Given:

Total kittens= 46

So,

Mean= Total mass/ number of kittens

mean= 0.8* + 1*3 + 1.2*4+ 1.4 * 6+ 1.6*8+ 1.8*8+ 2*7+ 2.2*5 + 2.4 * 2 + 2.6*1+3.8*1 / 46

Answer:

(see explanation below)

Step-by-step explanation:

The x-intercept is where the line intersects with the x-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the x-axis at (-2, 0). Therefore, the x-intercept is -2.

The y-intercept is where the line intersects with the y-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the y-axis at (0, 4). Therefore, the y-intercept (also represented by the variable b) is 4.

The rules of operations states that we deal with parentheses first. So, inside the parentheses, we have, 2 times 3. Multiply that. That gives us 6. So now, the equation looks like this:

(6)^2 + 5^2

Now we have to work with the exponents. So, square both numbers.

(6)^2 = 36

5^2 = 25

Now we have:

36 + 25

Now we add. 36 + 25 = 61

61 is your answer.
