The cross section is shaped like a circle.

A cone is a three-dimensional geometric object with a flat base and a smooth transition to the apex or vertex.

If a cone is sliced such that the cross section is perpendicular to its base and intersects its vertex, the cross section will be a circular shape. This is because the cross section cuts through the entire cone at a right angle, producing a circle that is defined by the curved surface of the cone and the slicing plane. The diameter of the circle is equal to the base diameter of the cone, and its center is located at the midpoint of the base.

Answer: 8

Step-by-step explanation:

CF looks like the radius of the circle.

ED looks like the diameter.

.: ED = 2 x CF = 2 x 4 = 8

.: ED = 8

Answer:

The length of ED, or the diameter, is 8

Step-by-step explanation:

As the other person explained, CF is the radius, as the radius is from the centermost point to the edge.  I also see that ED is the diameter, as the diameter is from edge to edge, going through the centermost point.  Therefore, since the diameter is double the radius, we can solve this with the following equation:

2 * r = d, where r is radius and d is diameter.

2 * 4 = d

8 = d

Answer: 1/5

Step-by-step explanation:

When dividing fractions, use the strategy of KCF (keep, change, flip). Keep the first fraction (this is a must) and then flip the second fraction.

In this case it would be 6/5. Then multiply both fractions, this would be 1 by 6 and 6 by 5. (6/30) in simplest form is 1/5, in the end to get the simplest form you would have to divide both the numerator and denominator by their common factor.

Answer:

0.86

Step-by-step explanation:

Probability of at least one set is green is

P = P(GG) + P(Green,not Green) + P(Not green, Green)

= (0.8 X 0.6) + (0.8x 0.4) + (0.2x 0.3)

=> 0.48 + 0.32 + 0.06

= 0.86

The company needs to adjust the bottling procedures since p < α i.e., 0.0117 < 0.10. Using z-score test statistics, the required value is obtained.

The mean of a dataset is the sum of all values divided by the total number of values. It's the most commonly used measure of central tendency and is often referred to as the “average.”

Deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean.

How to calculate the z-score?

The z-score is calculated by

z = ( - μ)/(σ/√n)

Where :- sample mean; μ - population mean; σ - standard deviation; n - sample size.

It is given that,

Population mean μ = 12 oz

Sample size n = 40

Sample mean  = 12.2 oz

Standard deviation σ = 0.7 oz

Constructing the test hypothesis as below:

H0: μ = 12 oz

Ha: μ < 12 oz (as close as possible)

Then, the z-score is

z = (12.2 - 12)/(0.7/√40)

 = 0.2/0.1106

 = 1.808

Thus, the required p-value for the obtained test score is p = 0.0117 from the distribution table.

Since p(0.0117) < 0.10(significance level), the null hypothesis is rejected.

Therefore, the company needs to adjust the bottling procedures since the mean volume of all beverages differs from 12 oz.

Step-by-step explanation:

25 cents = $0.25

the ratio is 5/0.25 (5 dates for $0.25)

now we need to convert this to $5 in the denominator. and we need to multiply the numerator with the same factor.

and then the numerator will tell us how many dates we get for $5 in the denominator.

0.25 × x = 5

x = 5/0.25 = 20

indeed, 20 quarters = $5

so, we do

Step-by-step explanation:

The proportion of the variation in the dependent variable y that is explained by the estimated regression equation is measured by the coefficient of determination.

What is coefficient of determination?

The effectiveness of a statistical model in forecasting a result is shown by the coefficient of determination (R²). The dependent variable in the model is a representation of the result.

R² can have a value of 0 or 1, with 1 being the maximum achievable. Simply said, a model's R² will be closer to 1 the more accurate its predictions are.

R² is a more precise measure of goodness of fit. The amount of volatility in the dependent variable that the model can account for.

You can typically tell whether your linear regression data's R² is high or low by graphing it. The graphs below, for instance, display two sets of simulated data:

Dots represent the observations.

The line of best fit, or predictions of the model, is displayed as a black line.

Answer:

The function rule is: \(y = -3x-5\)

Step-by-step explanation:

Using the given input/output values, we can take two pairs of input-output values for finding the rule.

The function is a linear function as the input and output are changing linearly.

Required pairs are:

(1,-8)  and (2, -11)

The general rule for linear function is:

\(y = mx+b\)

m is the slope of the function calculated using the formula

\(m = \frac{y_2-y_1}{x_2-x_1}\)

Putting the values

\(m = \frac{-11+8}{2-1}\\m = \frac{-3}{1}\\m = -3\)

Putting in equation

\(y = -3x+b\)

To find the value of b, putting (1,-8) in the equation

\(-8 = -3(1) +b\\-8 = -3+b\\-8+3 = b\\b = -5\)

Putting the values

\(y = -3x-5\)

Hence,

The function rule is: \(y = -3x-5\)

Answer:

C) 18

Step-by-step explanation:

All you have to do is solve the equation.

2.25x + 5 = 45.50 (subtract 5 on each side)

2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)

x = 18

40.50/2.25 = 18

Answer:

18 Miles

Step-by-step explanation:

If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.

Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

a) The circle crosses the y-axis at the points (0, 6) and (0, -2). b) the radius of the circle is 5. c) (i) The length of CP is √34. (ii) The length of PQ is 10.

(a) To find the y-coordinates of the points where the circle crosses the y-axis, we substitute x = 0 into the equation of the circle:

0² + y² + 6(0) - 4y = 12

y² - 4y = 12

y² - 4y - 12 = 0

To solve this quadratic equation, we can factor it:

(y - 6)(y + 2) = 0

Setting each factor to zero, we find two possible values for y:

y - 6 = 0 => y = 6

y + 2 = 0 => y = -2

Therefore, the circle crosses the y-axis at the points (0, 6) and (0, -2).

(b) To find the radius of the circle, we can complete the square to rewrite the equation of the circle in standard form:

x² + y² + 6x - 4y = 12

(x² + 6x) + (y² - 4y) = 12

(x² + 6x + 9) + (y² - 4y + 4) = 12 + 9 + 4

(x + 3)² + (y - 2)² = 25

Comparing this equation with the standard form of a circle, (x - h)² + (y - k)² = r², we can see that the center of the circle is at (-3, 2) and the radius is √25 = 5.

Therefore, the radius of the circle is 5.

(c) (i) To find the length of CP, we can use the distance formula between two points. The coordinates of C are (-3, 2), and the coordinates of P are (2, 5).

The distance formula is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the coordinates into the formula, we have:

CP = √((2 - (-3))² + (5 - 2)²)

= √(5² + 3²)

= √(25 + 9)

= √34

Therefore, the length of CP is √34.

(ii) To find the length of PQ, we can use the fact that PQ is a tangent to the circle. The radius of the circle is 5, and the line segment CP is perpendicular to PQ.

Since CP is perpendicular to PQ, CP is the radius of the circle. Therefore, CP = 5.

Therefore, the length of PQ is equal to 2 times the length of CP:

PQ = 2 * CP

= 2 * 5

= 10

Therefore, the length of PQ is 10.

To find the corresponding points on the graph obtained by shifting f up 1 unit and to the left 3 units, we apply the given transformations to the original points.

For the point (-3, 5), shifting it up 1 unit gives us (-3, 5 + 1) = (-3, 6). Then, shifting it to the left 3 units gives us (-3 - (-3), 6) = (0, 6).

For the point (4, -2), shifting it up 1 unit gives us (4, -2 + 1) = (4, -1). Then, shifting it to the left 3 units gives us (4 - (-3), -1) = (7, -1).

Suppose that the bug starts at the origin (0,0) and travels a distance of a units due east on the first day, and that there is a real number r with 0<r < 1 such that each day after the first, the bug walks r times as far as the previous day. On day n, the bug travels along the vector v that has magnitude ar^{n-1} and direction (cos(n.60°), sin(n.60°)). Then P is the terminal point of the infinite sum of the vectors v1 , v2 .... coordinate of this sum is

a(cos 0° + r cos 60° + r² cos 120° + .......)

Because the angles repeat after 6 terms, this sum is equal to

where S  =cos0 +r cos60 + r^{2} cos120.....

Similarly , T = sin 0 + r Sin60 + ...

Answer:

The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal is 20 times

Step-by-step explanation:

The given information are;

For the Lazarus' Boat Rentals company

The yearly charges by Lazarus' boat company = $105

The charge each time a member rents  a boat  = $9.50

For the Robert's Boat Rentals company

The yearly charges by Robert's boat company = $0

The charge each time a member rents  a boat  = $14.75

Let the number of times required before the charges for both Lazarus' Boat Rentals company and Robert's Boat Rentals company to be equal, we have;

$105 + $9.50 × t = $14.75 × t

∴ t = $105/($14.75 - $9.50) = 20 times
