In a density curve, the proportion of data is represented by the area under the curve. So option B is correct.

The probability that an observation chosen at random falls within a given interval is represented by the area under a density curve, which is a smooth representation of a probability distribution. As a result, the area under the curve between the respective points is proportional to the percentage of data that falls inside a given range.

The area under the curve that directly represents the proportion of data. The intervals of values on the vertical and horizontal axes are used to plot the curve and are important for interpreting the graph, but they do not directly represent the proportion of data. The length of the curve is not relevant for determining the proportion of data, as it can vary depending on the scaling of the graph.

Answer: 37

Step-by-step explanation:

let x be the number of students who pass "fante". Then the number of students who passed "Ga" will be x + 6.

with the added information that 8 students passed both we can say:

(x + x + 6) - 8 = 60

2x + 6 = 68

2x = 62

x = 31

.: x + 6 = "only Ga pass" = 37

The question does not make it clear if it is asking for students who *only* passed Ga, or students who passed Ga + those who passed both. I'll assume the former though. Otherwise the answer would be 37 + 8 = 45 students

Measure of angle B is 36.87°.

Trigonometric functions are defined as the real functions or the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given is a right angled triangle.

We have to find measure of angle B.

Cosine of an angle in a right angled triangle is equal to the ratio of it's adjacent side to the hypotenuse.

Hypotenuse = AB = 5

Adjacent side to B = CB = 4

Cos B = 4/5

∠B = Cos⁻¹ (4/5)

     = 0.6435 radians

Answer:

W when c = 4 is 0.128.

Step-by-step explanation:

The relationship between A, C and W can be represented by the following equations:

A = k√c

W = m/a^3

Where k and m are constant of proportionality.

Since A is directly proportional to the square root of c, we can write k = A/√c. Substituting the values of A and C when c = 49, we have:

k = 35/√49 = 35/7

Since W is inversely proportional to a^3, we can write m = W * a^3. Substituting the values of W and A when a = 2, we have:

m = 16 * 2^3 = 128

Now we have both k and m, we can find the value of W when c = 4.

A = k * √c = 35/7 * √4 = 10

W = m/a^3 = 128/10^3 = 0.128

So, the value of W when c = 4 is 0.128.

The total number of new cars made by a factory from 1,254 tires as each car required four tires is equal to 314 ( round off to nearest whole number ).

Total number of tires in the factory is equal to 1,254

Number of tires required by each new car is equal to 4 tires.

The total number of new car made by a factory is equal to :

4 tires = 1 new car

⇒ 1 tire = ( 1 / 4 ) new car

⇒ 1,254 tires = 1,254 ×  ( 1 / 4 ) new car

⇒ 1,254 tires = ( 1,254 / 4 ) new cars

⇒ 1,254 tires =  313.5 new cars

But number of new cars cannot be in the decimals or fraction.

Round off to the nearest whole number .

⇒ 1,254 tires =  314 new cars ( nearest whole number )

Therefore the total number of new cars made by a factory is equal to 314 new cars.

Anyways,

The height of the nth bounce can be calculated using the formula:

h_n = h_1 * 0.68^(n-1)

Where h_1 is the height of the first bounce, h_n is the height of the nth bounce, and 0.68 is the percentage of the height lost with each successive bounce.

Substituting the given values, we have:

h_9 = 5 * 0.68^(9-1)

h_9 = 5 * 0.68^8

h_9 = 5 * 0.265

h_9 = 1.325

So the height of the 9th bounce would be approximately 1.3 feet, rounded to the nearest tenth.

A polynomial term is an expression composed of constants, variables, and exponents.

A polynomial term is an expression composed of constants, variables, and exponents. Constants are the numerical values that don't change, while variables are values that can change. Exponents are numbers that indicate how many times a number is multiplied by itself. For example, 2^3 means 2 multiplied by itself 3 times, or 8. A polynomial term is an expression that combines constants, variables, and exponents, such as 6x^2 - 3x + 5. In this expression, 6, -3, and 5 are constants, x is a variable, and 2 and 1 are exponents. A polynomial term can also contain fractions, such as (2x + 1)/3. In this case, 2, 1, and 3 are constants, and x is a variable. Polynomial terms are the building blocks of polynomials, which are equations that consist of multiple polynomial terms.

a) Formula that gives the total yearly expense as a linear function of the number of dairy cows is E = 21,000 + 2,000C.

b) Formula that gives I as a linear function of C is I = 7,000C. The smallest number of cows the dairy needs to break even is 5.

(a) Let's call the number of dairy cows "C".

The yearly expense for maintaining the barns and equipment is a fixed cost of $21,000.

The yearly expense for feeding and caring for each dairy cow is $2,000.

To find the total yearly expense, we can add the fixed cost of maintaining the barns and equipment to the variable cost of caring for the cows:

E = 21,000 + 2,000C

This is a linear equation that gives the total yearly expense as a function of the number of dairy cows.

(b) Each dairy cow produces 3,500 gallons of milk per year.

The dairy sells milk for $2.00 per gallon.

To find the yearly income for the dairy, we can multiply the number of gallons of milk produced by the price per gallon:

I = 2.00(3,500)C = 7,000C

This is a linear equation that gives the yearly income as a function of the number of dairy cows.

To determine the smallest number of cows the dairy needs in order to break even, we need to find the point where the yearly income is equal to the yearly expense.

Setting I = E, we get:

7,000C = 21,000 + 2,000C

Simplifying and solving for C, we get:

5,000C = 21,000

C = 4.2

Since we cannot have a fraction of a cow, we round up to the nearest whole number.

To choose an appropriate scale for the y-axis.

we need to consider the range of values in the data set.

The lowest value is 15 minutes

and the highest value is 60 minutes

Range of values is 60 - 15 = 45 minutes.

It's best to choose a scale that divides the range of values into equal intervals.

One possible option is to use a scale where each unit represents 5 minutes of time. This would allow us to represent the data accurately without making the bars too small or too large.

The equation that represents the given scenario is 35 + 0.45d = 63.80

The linear equation is a mathematical statement that is solved for an unknown value. The linear equation is straight in a graph where the variable will represent an unknown value in the given problem.

To find the required equation, first calculated the charge according to the given problem and form the linear equation using the given variable.
