The equation representing the relationship between the number of weeks (w) and the number of books collected (b):

b = 10w + 0

b = 10w

We can observe from the table that the number of books collected increases by 10 for each week.

Thus, there is a linear relationship between the number of weeks (w) and the number of books collected (b). We can represent this relationship using the equation:

b = mw + c

where b is the number of books collected, w is the number of weeks, m is the slope (rate of change), and c is the y-intercept (number of books collected at week 0).

The slope (m) is the change in the number of books collected per week, which is 10. We can now find the y-intercept (c) by substituting one of the points from the table into the equation. Let's use the point (1, 10):

10 = 10 * 1 + c

c = 0

Now we have the equation representing the relationship between the number of weeks (w) and the number of books collected (b):

b = 10w + 0

b = 10w

Answer:

x = 45 degrees

Step-by-step explanation:

All angles in a triangle will add up to 180 degrees.  So far we have 57 degree of 180.  We also see a supplementary angle, with one side being 102 degrees, so the other is 78 degrees, because it must add up to 180.  We see that the arrows in the bases show that the corners are even, so now we know two corners: one with 57 degrees and the other with 78.  

Now, follow this equation to find x:

57 + 78 + x = 180

135 + x = 180

According to the given information, if 5 cups of flour are used in the recipe, we should use 5/3 cups of sugar.

Multiplication is an arithmetic operation that involves combining two or more numbers to get a product. It is a way of repeatedly adding a number to itself a certain number of times. The number being multiplied is called the multiplicand, while the number of times it is being multiplied is called the multiplier. The result of the multiplication operation is called the product

If the recipe requires 2 cups of flour for every 2/3 cups of sugar, we can write this relationship as:

2 cups of flour : 2/3 cups of sugar

To find out how many cups of sugar should be used if 5 cups of flour are included, we can set up a proportion:

2 cups of flour / 2/3 cups of sugar = 5 cups of flour / x cups of sugar

where x is the number of cups of sugar we want to find.

To solve for x, we can cross-multiply:

2 cups of flour * x cups of sugar = 2/3 cups of sugar * 5 cups of flour

2x = (2/3) * 5

2x = 10/3

x = 5/3

Therefore, According to the given information,  if 5 cups of flour are used in the recipe, we should use 5/3 cups of sugar.

Answer:

If the point (1,5) lies on a circle with center (0,0), then the radius of the circle is the distance from the center to the point (1,5), which is:

r = sqrt((1-0)^2 + (5-0)^2) = sqrt(26)

So the equation of the circle is:

x^2 + y^2 = 26

To find a point in quadrant 2 that lies on the circle, we need to find a point with a negative x-coordinate and a positive y-coordinate that satisfies this equation.

Among the given options, only (a) (-5,1) and (e) (-2,3) have a negative x-coordinate. Let's check if they satisfy the equation of the circle:

For point (a) (-5,1):

x^2 + y^2 = 26

(-5)^2 + 1^2 = 26

25 + 1 = 26

This point does not lie on the circle.

For point (e) (-2,3):

x^2 + y^2 = 26

(-2)^2 + 3^2 = 26

4 + 9 = 26

This point also does not lie on the circle.

Therefore, among the given options, there is no point in quadrant 2 that lies on the circle.

Step-by-step explanation:

since the center of the circle is at the origin, that means that the circle is evenly going through all four quadrants - one quarter arc after the other.

the point (1, 5) is in the first quadrant (upper right one, positive x, positive y).

the circle arc in the second quadrant (upper left one, negative x, positive y) is the mirrored image of the arc in the first quadrant across the y-axis.

so, the point on it gets mirrored too.

that means, it's coordinates are then the same y and the x is converted to its negative value :

(-1, 5)

that is the easily identifiable point in the second quadrant that has to be on the circle.

The probability that the mean tariff rate of 400 randomly selected​ railroad-car shipments of ethanol will be within ​$80 of the mean tariff rate of all​ railroad-car shipments of ethanol is: 0.305.

The interpretation of the statement that the probability of the sample mean being within $80 of the population mean is 0.305 is that if we take multiple samples of 400 ethanol railroad-car shipments, about 30.5% of the time, the sample mean tariff rate will be within $80 of the population mean tariff rate.

To arrive at the propability, we will first list the data as follows:

Standard deviation of tariff rates, σ = $1200

Sample size, n = 400

Margin of error, E = $80

Standard deviation of sample mean = σ/√n = 1200/√400 = 60

To find the probability, we need to calculate the z-score for the margin of error.

z = E / standard deviation of sample mean = 80 / 60 = 4/3.

When we use the standard normal distribution table, we will arrive at  the probability of a z-score between -1.33 and 1.33. This probability is approximately 0.305.

The diameter of the circle is approximately 947.15 meters.

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference and r is the radius of the circle.

We can use this formula to find the radius of the circle given its circumference:

C = 2πr

942 = 2πr

Dividing both sides by 2π, we get:

r = 942/2π

Now, we can use the formula for the diameter of a circle in terms of its radius:

d = 2r

Substituting the value we found for r, we get:

d = 2(942/2π) = 942/π

Using a calculator to approximate π as 3.14, we can evaluate the expression to get:

d ≈ 947.15 meters

Answer:

The perpendicular bisector of a line segment AB is the line that passes through the midpoint of AB and is perpendicular to AB.

To find the equation of the perpendicular bisector of segment AB, we can follow these steps:

M = ( (x1 + x2)/2, (y1 + y2)/2 )

where A = (x1, y1) and B = (x2, y2).

M = ( (-6 + 14)/2, (4 - 12)/2 ) = (4, -4)

m = (y2 - y1) / (x2 - x1)

m = (-12 - 4) / (14 - (-6)) = -16/20 = -4/5

m_perp = -1/m

m_perp = -1/(-4/5) = 5/4

y - y1 = m(x - x1)

y - (-4) = (5/4)(x - 4)

Simplifying, we get:

y + 4 = (5/4)x - 5

(5/4)x - y - 9 = 0

So, the formula that expresses the fact that an arbitrary point P(x, y) is on the perpendicular bisector of segment AB is:

The mean absolute deviation of the entire data set is 4.

To find the mean absolute deviation (MAD) of the given data set, we need to follow these steps:

Calculate the mean (average) of the data set.

Subtract the mean from each data point to find the deviation.

Take the absolute value of each deviation.

Calculate the mean of the absolute deviations.

Let's calculate the MAD for the given data set: 18, 13, 6, 14, 11, 22.

Calculate the mean.

Mean = (18 + 13 + 6 + 14 + 11 + 22) / 6 = 84 / 6 = 14.

Calculate the deviation for each data point.

Deviation = data point - mean.

Deviation for 18 = 18 - 14 = 4.

Deviation for 13 = 13 - 14 = -1.

Deviation for 6 = 6 - 14 = -8.

Deviation for 14 = 14 - 14 = 0.

Deviation for 11 = 11 - 14 = -3.

Deviation for 22 = 22 - 14 = 8.

Take the absolute value of each deviation.

Absolute deviation = |deviation|.

Absolute deviation for 4 = |4| = 4.

Absolute deviation for -1 = |-1| = 1.

Absolute deviation for -8 = |-8| = 8.

Absolute deviation for 0 = |0| = 0.

Absolute deviation for -3 = |-3| = 3.

Absolute deviation for 8 = |8| = 8.

Calculate the mean of the absolute deviations.

Mean absolute deviation = (4 + 1 + 8 + 0 + 3 + 8) / 6 = 24 / 6 = 4.

If the radius of smaller-saw is 1.25 in, and radius of larger-saw is 2 inches, then larger-saw is 4.71 inches greater the smaller-saw.

The "Circumference" of a circle is defined as the distance around the boundary of a circle, it is also called perimeter of circle;

The diameter of the smaller saw can be calculated as:

⇒ diameter = 2 × radius = 2 × 1.25 inches = 2.5 inches;

The diameter of the larger saw is 1.5 inches greater than the diameter of the smaller saw, which means,

⇒ diameter of larger saw = diameter of smaller saw + 1.5 inches,

⇒ diameter of larger saw = 2.5 inches + 1.5 inches = 4 inches;

So, Circumference of circle is = 2 × π × radius;

The Circumference of "smaller-saw" = 2 × 3.14 × 1.25 inches,

⇒ circumference of smaller saw = 7.85 inches;

circumference of "larger-saw" = 2 × 3.14 × 2 inches

⇒ circumference of larger saw = 12.56 inches;

The difference in circumference between the two saws is:

⇒ circumference of larger saw - circumference of smaller saw

Step-by-step explanation:

If a person stands at a point and looks up at an object, the angle between their horizontal line of sight and the object is called the angle of elevation.

To find how far away from the building you are standing, we need to find the distance labelled "x" on the attached diagram. We can do this by modelling the given scenario as a right triangle and solving for x by using the tangent trigonometric ratio.

[tex]\boxed{\tan \theta=\sf \dfrac{O}{A}}[/tex]

where:

Given information:

As your eyes are 5 ft above the ground, we have to model the line of sight as 5 ft above ground level.  Therefore, the side of the right triangle opposite the angle of elevation is the height of the building less 5 ft:

[tex]\implies \sf 1000 \; ft - 5\; ft=995 \; ft[/tex]

Let "x" be the horizontal distance between you and the building.

Therefore, the values to substitute into the tangent ratio are:

Substitute these values into the ratio and solve for x:
