If Joel and Duncan split the 15 ounces of hot chocolate evenly, then they each got half of the container.

To find out how much hot chocolate each boy got, we need to divide the total amount of hot chocolate by the number of people sharing it. Since there are two boys, we can divide 15 by 2 to get the amount of hot chocolate each boy received: 15 ÷ 2 = 7.5

Therefore, each boy got 7.5 ounces of hot chocolate to drink while they went sledding.It's important to note that when dividing something equally between two people, we divide by two since there are two individuals.

In this case, each boy received half of the container, or half of the total amount of hot chocolate. This type of division is known as "fair" or "equal" sharing, as both parties receive an equal portion.

The expression of total number of hours worked by the 15 employees is 505 .

An expression is a mathematical statement that combines numbers, variables, and/or operators to represent a quantity or relationship. It can be evaluated or simplified, but does not have an equals sign and is not a complete equation.

To find the total number of hours worked by the 15 employees, we need to add up the hours worked by each individual employee.

Let's say that employee 1 worked x1 hours, employee 2 worked x2 hours, and so on, up to employee 15 who worked x15 hours. Then, the total number of hours worked by the 15 employees can be expressed as:

Total number of hours = x1 + x2 + ... + x15

To solve this expression, we need to know the specific number of hours worked by each employee. If we are given this information, we can simply substitute the values into the expression and add them up to find the total number of hours.

we can calculate the total number of hours worked as:

Total number of hours = 40 + 30 + 35 + ... + 20

The outer perimeter is 76.12 ft according to given question.

what is perimeter?

Perimeter is a term used in geometry to refer to the total distance around the outside of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape. For example, in a rectangle, the perimeter is calculated by adding the length of all four sides. In a circle, the perimeter is called the circumference and is calculated as the distance around the edge of the circle.

The perimeter of a semicircle is the sum of the length of its straight edge and half the circumference of the circle.

In this case, the radius of the semicircle is given as 8 units, so the circumference of the corresponding full circle is 2πr = 2π(8) = 16π units.

Half the circumference of the circle is therefore 8π units.

The straight edge of the semicircle is simply the diameter of the circle, which is twice the radius, or 2(8) = 16 units.

So, the perimeter of the semicircle is the sum of the straight edge and half the circumference:

Perimeter = 16 + 8π

Using approximate value for pi (π = 3.14), the perimeter can be expressed as:

Perimeter ≈ 16 + 8(3.14) ≈ 40.12 units.

The perimeter of a rectangle is given by the sum of the lengths of its four sides.

In this case, the length of the rectangle is given as 10 units and its width is given as 8 units.

Therefore, the perimeter of the rectangle is:

Perimeter = 2(Length + Width) = 2(10 + 8) = 2(18) = 36 units.

So, the perimeter of the rectangle with length 10 units and width 8 units is 36 units.

Step-by-step explanation:

after a little bit of thinking and experimenting we find that the function multiplied x by 6 and subtracts 2.

y = 6x - 2

formally, we find this by using the normal linear form

y = ax + b

and we use the given data points to find a and b.

4 = a×1 + b = a + b

10 = a×2 + b = 2a + b

so, by adding a on one side and adding 6 on the other side, we keep the balance.

therefore, a = 6

the first equation gives us then

4 = 6 + b

b = -2

and that's it.

so,

for x = 10 we get as output (y)

Answer:

C. (45+2+7)-(43+2+7) / 5+3

Step-by-step explanation:

To find the average rate of change of h(x) on the interval -3 ≤ x ≤ 5, we need to evaluate the following expression:

[h(5) - h(-3)] / (5 - (-3))

We have:

h(5) = 4(5) + 2 + 7 = 29

h(-3) = 4(-3) + 2 + 7 = -5

Substituting into the formula, we get:

[29 - (-5)] / (5 - (-3)) = 34 / 8 = 17 / 4

Therefore, the expression that gives the average rate of change of the function h(x) on the interval -3 ≤ x ≤ 5 is:

(a) μx  15.55 cubic feet. The standard deviation is the square root of the variance, i.e., θx = 1.881 cubic feet

The mean, or expected value, of x can be calculated as μx = Σ(xi * P(xi)) where xi are the possible values of x and P(xi) are their corresponding probabilities. Thus, μx = (13.40.2) + (15.80.5) + (19.3*0.3) = 15.55 cubic feet.

To calculate the standard deviation, we first need to calculate the variance, which can be obtained as θ²x = Σ((xi-μx)² * P(xi)). Thus, θ²x = ((13.4-15.55)²0.2) + ((15.8-15.55)²0.5) + ((19.3-15.55)²*0.3) = 3.54.

Therefore, the standard deviation is the square root of the variance, i.e., θx = √3.54 = 1.881 cubic feet (rounded to four decimal places).

C.) P = 3(a+2)-4

The formula which describes the relation between the height of the apple tree and the height of the pine tree p is P=3(a+2)-4, the correct option is C.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

Growth of apple tree= 2feet

Now,

Let's call the original height of the apple tree "h". According to the problem, if the apple tree grew 2 feet and then tripled its height, it would become 4 feet shorter than the pine tree. So we can write:

3(h+2) - 4 = p

Simplifying, we get:

3h + 2 = p

Now we can see that option (D) P=3a+10 is very similar to our expression, but it has a constant term of 10 instead of 2. This constant term does not match the problem statement, which says that the apple tree would be 4 feet shorter than the pine tree, not taller. Therefore, option (D) is not the correct answer.

Option (A) P-4=3a+2 also does not match the problem statement. If we solve for p, we get:

P = 3a + 6

This means that the apple tree would be 6 feet shorter than the pine tree, not 4 feet shorter as stated in the problem.

Option (B) P=2(a+3)+4 also does not match the problem statement. If we solve for p, we get:

P = 2a + 10

This means that the apple tree would be 10 feet shorter than the pine tree, not 4 feet shorter as stated in the problem.

Option (C) P=3(a+2)-4 matches our expression from earlier. If we solve for p, we get:

P = 3a + 2

Therefore, by equation the answer will be P=3(a+2)-4.

The dimensions of the gray rectangle are approximately 61.9 km by 218.1 km.

The distance around a rectangle's outside edge is known as its perimeter. It is computed by summing the measurements of the rectangle's four sides. The perimeter P of a rectangle with sides of length l and width w is given by:

P = 2l + 2w.

By understanding that a rectangle contains two pairs of equal sides (length and breadth), and that the distance around the rectangle is equal to the total of these four sides, one may deduce this formula.

Let us suppose the dimensions of the gray triangle as x and y.

The perimeter of rectangle is given as:

P = 2(1 + b)

For the blue triangle we have:

P = 2(72 + 68)

For the gray triangle we have;

P = 2(x + y)

Equating the two since they are equal we have:

2(72 + 68) = 2(x + y)

280 = x + y

We also know the area of the gray triangle thus:

xy = 3876

Substituting y = 280 - x into the second equation, we get:

x(280 - x) = 3876

x² - 280x + 3876 = 0

x = (280 ± √(280² - 4(1)(3876))) / 2

x ≈ 62.7 or x ≈ 61.9

We may discard the negative answer since a rectangle's dimensions cannot be negative.

Substituting the value of x we have:

y = 280 - 61.9 = 218.1 km.

Hence, the dimensions of the gray rectangle are approximately 61.9 km by 218.1 km.

In attempts to reduce greenhouse gas emissions and the effects of climate change, these sources must be taken into account.

A mathematical equation is a claim that two expressions are equal, typically represented with an equal sign (=) between them. The terms "left hand side" (LHS) and "right hand side" (RHS) of the equation, respectively, refer to the expressions on either side of the equal sign. Equations are a common tool for problem solving because they may be used to depict relationships between variables or quantities and to determine the value(s) of the unknown variable(s) that satisfies the equation. For instance, the link between the variables x and the integers 2, 5, and 11 is represented by the equation 2x + 5 = 11. Finding the value of x that makes the left and right sides of the equation equal is necessary to solve this equation.

The 90% confidence interval for the average number of hours of sleep for working college students is between 6.15 and 6.85 hours.

Therefore, the answer is option (a) 6.15 and 6.85 hours.

A confidence interval is a statistical range of values within which we can be reasonably confident that the true value of a population parameter lies. It is commonly used in inferential statistics to estimate an unknown population parameter, such as a mean or a proportion, based on a sample from that population.

To calculate the 90% confidence interval for the average number of hours of sleep for working college students, we'll use the formula:

Confidence Interval = Sample Mean ± (Critical Value x Standard Error)

Where:

Sample Mean: 6.5 hours (the average number of hours of sleep)

Critical Value: t-value corresponding to a 90% confidence level with 100 degrees of freedom (101 students - 1)

Standard Error: Standard Deviation / Square Root of Sample Size

Let's plug in the values and calculate the confidence interval:

Standard Error = 2.14 / √101 ≈ 0.2139

Confidence Interval = 6.5 ± (1.660 x 0.2139)

Confidence Interval = 6.5 ± 0.3546

Lower Bound = 6.5 - 0.3546 ≈ 6.1454

Upper Bound = 6.5 + 0.3546 ≈ 6.8546

Rounding to the hundredths place, the 90% confidence interval for the average number of hours of sleep for working college students is between 6.15 and 6.85 hours.
