In the United States, most competitive swimming pools are 25 yards long. This is the most standard length competition pool, and the one most commonly mistaken for an Olympic sized pool (by those who were not competitive swimmers).Most US high schools, public recreation centers, universities and YMCA's have 25-yard pools. Swimmers refer to this type of pool as "short course", or "short course yards". On paper, the acronym is SCY.

The percent error of the estimate is -2.14%

In this question, the figures are given as

Estimate = 5.5 cm

Actual = 5.62 cm

The percentage of the error is then calculated using the following equation

Error percentage = (Estimate - Actual)/Actual * 100%

Substitute the known values in the above equation, so, we have the following representation

Error percentage = (5.5 - 5.62)/5.62 * 100%

Evaluate

Error percentage = -2.14%

Hence, the error percentage is -2.14%

The value of Y when X = 4 in the regression line that has the slope of 2,5 is a) 26

The equation of a straight line with slope m and y-intercept b is given by  :

y = mx + b.

Where

1. y is the dependent variable (i.e., the value of y depends on x)

2. x is the independent variable

3. m is the slope of the line, representing the rate of change of y with respect to x

4. b is the y-intercept, the point where the line intersects the y-axis when x = 0.

This equation can be used to describe the relationship between two variables, and it can be used to make predictions about the value of y for a given value of x, or to find the value of x for a given value of y.

From the question we have the following information :

1. Slope ( or m ) is 2.5

2. The intercept ( y-intercept or b ) is 16

So, using the values given (slope = 2.5, y-intercept = 16), we have:

y = mx + b

y = 2.5x + 16

When X is 4, substituting X with 4 in the equation gives us:

y = 2.5 * 4 + 16 = 26

So the value of Y when X is 4 is 26. Answer: a) 26.

Using L'hopital we can see that the limit is equal to 1/22

Here we want to take the limit of x tending to zero for x/sin(22x)

Notice that when x = 0, both numerator and denominator are zero, so we need to take the limit of the first derivatives, for:

y = x

y' = 1

And for:

y = sin(22x)

y' = 22*cos(22x)

Now taking the limit we will get:

\(\lim_{x \to 0} \frac{1}{22cos(22x)} = \frac{1}{22cos(0)} = 1/22\)

That is the value of the limit.

The length of line segment AB is 5 units.To find the length of line segment AB, we can use the distance formula, which is based on the Pythagorean theorem.

The distance formula calculates the distance between two points (x1, y1) and (x2, y2) in a coordinate plane.

Let's calculate the length of AB using the given coordinates for points A and B:

Coordinates of point A: A = (4, -5)

Coordinates of point B: B = (7, -9)

The distance formula is given by:

\(d = [(x2 - x1)^2 + (y2 - y1)^2]\)

Substituting the coordinates of A and B into the formula:

\(d = [(7 - 4)^2 + (-9 - (-5))^2]\\d =[(3)^2 + (-4)^2]\)

d = √[9 + 16]

d = √25

d = 5

Therefore, the length of line segment AB is 5 units.

The distance formula calculates the straight-line distance between two points in a two-dimensional space. In this case, it determines the distance between points A and B in the coordinate plane. By applying the formula and substituting the given coordinates, we find that the length of AB is 5 units.

The probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Since the probability density function is uniform, the probability of the friend being between 10 and 30 minutes late is equal to the area of the rectangle that lies between x = 10 and x = 30, and below the curve of the probability density function.

The height of the rectangle is equal to the maximum value of the probability density function, which is 1/30 since the interval of possible values for x is [0, 30] minutes.

The width of the rectangle is equal to the difference between the upper and lower limits of the interval, which is 30 - 10 = 20 minutes.

Therefore, the probability of the friend being between 10 and 30 minutes late is:

P(10 < x < 30) = (height of rectangle) x (width of rectangle)

= (1/30) x 20

= 2/3

≈ 0.6667

So the probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

Initial measure 63 inches

After dividing the sandwich by 3, the measure of one piece is 21 inches

After dividing one of the previous pieces of the sandwich by 3, the measure of one piece is 7 inches

After dividing one of the previous pieces of the sandwich by 2, the measure of one piece is 7/2 inches

Therefore, the longest piece measures 21 inches and the smallest piece measures 7/2. Subtracting 7/2 from 21, we have:

The length of AE¯¯¯¯¯ is 5√2 cm.

Since quadrilateral ABCD is a square, all four sides are congruent. Let's denote the length of one side as s. Therefore, the length of BD¯¯¯¯¯ is equal to s.

Given that the length of BD¯¯¯¯¯ is 10 cm, we can conclude that s = 10 cm.

Now, we need to find the length of AE¯¯¯¯¯. Looking at the square, AE¯¯¯¯¯ is the diagonal connecting opposite corners.

In a square, the diagonal divides the square into two congruent right triangles. We can use the Pythagorean theorem to find the length of the diagonal.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the diagonal (the hypotenuse) is the same as the side length, s.

Applying the Pythagorean theorem:

s^2 = AE¯¯¯¯¯^2 + AE¯¯¯¯¯^2

10^2 = AE¯¯¯¯¯^2 + AE¯¯¯¯¯^2

100 = 2 * AE¯¯¯¯¯^2

AE¯¯¯¯¯^2 = 50

Taking the square root of both sides:

AE¯¯¯¯¯ = √50

Simplifying the square root:

AE¯¯¯¯¯ = √(25 * 2) = 5√2 cm

Now it should look like this: (90-((50/5)*6)) + 2

First, divide 50 by 5 and get 10

So now it will be like this: (90-(10 x 6) + 2

Next, multiply 10 by 6 and you'll get 60.

The problem is looks like this: (90 - 60) + 2

Then, subtract 60 from 90 and get 30.

The correct linear equation that shows the relationship between the two types of wood purchased by the contractor is option A. 45(x+3)=60x.

Let's break down the problem,

The contractor purchased 45 units of expensive wood and 60 units of cheap wood for the same total price.

Let's assume that the price of the 60 units of cheap wood is x.

According to the problem, 45 units of expensive wood cost $3.00 more per unit than 60 units of cheap wood. This means that the price of the 45 units of expensive wood is (x+3).

Now, we can set up the equation,

The total cost of 45 units of expensive wood + Total cost of 60 units of cheap wood = Total cost of wood purchased

45(x+3) + 60(x) = 105(x)

Simplifying this equation, we get:
45x + 135 + 60x = 105x
105x = 135
x = 1.29

Therefore, the price of the 60 units of cheap wood is $1.29, and the price of the 45 units of expensive wood is $4.29.

Substituting the value of x in option A, we get:
45(x+3) = 45(1.29+3) = 45(4.29) = 193.05
60x = 60(1.29) = 77.4

Total cost of wood purchased = 193.05 + 77.4 = 270.45

This confirms that option A is the correct linear equation that shows the relationship between the two types of wood purchased.

Answer:

Step-by-step explanation:

Let x be the number of pounds of oak wood chips used and 75-x be the number of pounds of pine wood chips used.

The cost of x pounds of oak wood chips at $3.30 per pound is 3.30x dollars. The cost of (75-x) pounds of pine wood chips at $2.60 per pound is 2.60(75-x) dollars.

Since the total cost of the mixture is $2.80 per pound and there are 75 pounds in the mixture, the total cost of the mixture is 2.80(75) = 210 dollars.

Solving the equation 3.30x + 2.60(75-x) = 210 for x gives x ≈ 21.43.

Therefore, the lumber company used approximately 21.43 pounds of oak wood chips and 75-21.43 = 53.57 pounds of pine wood chips to make a 75-pound mixture costing $2.80 per pound.
