for both categorical and numerical variables the difference between the relative frequency and the percent frequency is option B: The percent frequency equals the relative frequency multiplied by 100.

Relative frequency and percent frequency are two measures of the frequency of an event or category within a data set.

Relative frequency is the ratio of the number of times an event or category occurs divided by the total number of events or categories.

Percent frequency is the relative frequency expressed as a percentage. This means that it is equal to the relative frequency multiplied by 100. In other words, the percent frequency represents the proportion of occurrences of an event or category as a percentage of the total number of events or categories.

So, the difference between relative frequency and percent frequency is that relative frequency is a ratio, while percent frequency is the same ratio expressed as a percentage.

When you write it this way you distribute it so 10 is outside the parenthesis so you time 10 to bout of the numbers inside of it then add.

Answer/Step-by-step explanation:

All numbers that are divisible by 9 are also divisible by 3.

Since 3 goes into 9, if 9 is a factor, 3 is also a factor.

Example:

81 is divisible by 9.

So, 81 is also divisible by 3.



Another example:

1,273,050 is divisible by 9.

So 1,273,050 is also divisible by 3.

But the other way around is not necessarily true. If 3 goes into a number, 9 may or may not go into the number.

That is, if a number is divisible by 3, you cannot necessarily know that it is divisible by 9.

Example (seems like it works):

18 is divisible by 3. 18 is also divisible by 9.

But it doesn't work every single time so it cannot be a rule.

Example(sometimes it doesn't work):

24 is divisible by 3.

24 is not divisible by 9.

The distance in feet from the bottom of the lighthouse to the ferry is 154 feet.

What is the angle of depression?

The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line. It is basically used to get the distance of the two objects where the angles and an object's distance from the ground are known to us.

The angle of depression is always measured from the horizontal.

A triangle is formed by the lighthouse, the ground, and the ferry. The angle of depression is not in the triangle, but it is equal to the angle of elevation at the ferry. (Alternate angles on parallel lines)

The angle at the top of the lighthouse, inside the triangle is:

90° − 37° = 53°

The distance to the boat is the side opposite the angle of 63° while the height of the lighthouse is the adjacent side.

opposite / adjacent = tan53°

distance / 116 = tan53°

distance = 116 × tan53°

= 153.932 feet

= 153.9 feet. (approximately)

Container 1: The unit rate for Container 1 from Home Depot is $14.98 per gallon. Container 2: The unit rate for Container 2 from Lowes is $115.00 per gallon. The unit rate for each container tells us how much one gallon of paint costs from each store.

The unit rate for the paint from Home Depot is $14.98 per gallon and the unit rate for the paint from Lowes is $115.00 per gallon. This tells us that the paint from Home Depot is cheaper than the paint from Lowes.

Step 1: To calculate the rate for each container, divide the cost of the container by the number of gallons in the container.

Container 1: $14.98 per gallon = $14.98 / 1 gallon

Container 2: $115.00 per gallon = $115.00 / 1 gallon

Step 2: To calculate the unit rate for each container, divide the cost of the container by the number of units in the container.

Container 1: $14.98 per gallon = $14.98 / 1 unit

Container 2: $115.00 per gallon = $115.00 / 1 unit

Step 3: The unit rate for each container tells us how much one gallon of paint costs from each store.

Container 1: The unit rate for Container 1 from Home Depot is $14.98 per gallon.

Container 2: The unit rate for Container 2 from Lowes is $115.00 per gallon.

The theory used in this question is the concept of unit rate, which is used to compare the prices of different products.

Unit rate is defined as the cost per unit of measure (e.g., price per gallon, price per pound, etc.).

In this case, we are using the unit rate of price per gallon to compare the prices of paint from Home Depot and Lowes.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] + [tex]\frac{2}{3}[/tex]  The common denominator is 12  make equivalent fractions with 12 as the denominator

[tex]\frac{1}{4}[/tex] x [tex]\frac{3}{3}[/tex] = [tex]\frac{3}{12}[/tex]

[tex]\frac{2}{3}[/tex] x [tex]\frac{4}{4}[/tex] = [tex]\frac{8}{12}[/tex]

[tex]\frac{3}{12}[/tex] + [tex]\frac{8}{12}[/tex] = [tex]\frac{11}{12}[/tex]

To complete the square for the equation x2 - 16x + 60 = -12, add 64 to each side of the equation. This will give us x2 - 16x + 124 = 52.

Then, factor out the coefficient of x2 (1) and the coefficient of x (16). This will give us (x - 8)2 = 52. Finally, subtract 52 from both sides to get (x - 8)2 = 0. Solving for x yields x = 8.

The probability that George drove given that he is late is approximately 0.355 or 35.5%.

Let's call the event of George being late "L". The problem is asking for P(Drives | L), which is the probability that George drove given that he is late.

We can use Bayes' theorem to find this probability:

P(Drives | L) = P(L | Drives) * P(Drives) / P(L)

P(L | Drives) is the probability that George is late given that he drove, which is given as 55%.

P(Drives) is the prior probability that George drives, which is given as 20%.

P(L) is the overall probability that George is late, which can be found by summing up the individual probabilities of George being late for each mode of transportation and weighting it by the corresponding prior probability of using that mode of transportation:

P(L) = P(L | Walks) * P(Walks) + P(L | Cycles) * P(Cycles) + P(L | Drives) * P(Drives) + P(L | Bus) * P(Bus)

P(L | Walks) is the probability that George is late given that he walks, which is given as 15%.

P(Cycles) is the prior probability that George cycles, which is given as 30%.

P(Bus) is the prior probability that George takes the bus, which is given as 40%.

P(L | Bus) is the probability that George is late given that he takes the bus, which is given as 20%.

Substituting these values into the formula for P(L) and simplifying:

P(L) = 0.15 * 0.10 + 0.10 * 0.30 + 0.55 * 0.20 + 0.20 * 0.40

= 0.155

Finally, substituting the values for P(L | Drives), P(Drives), and P(L) into the formula for P(Drives | L) and simplifying:

P(Drives | L) = 0.55 * 0.20 / 0.155 = 0.55 / 0.155 = 3.548

Answer:

Step-by-step explanation:

A) To find the length of AD, we first find the length of the CD.

CD = (BE + EC)/2 = (3x + 12 + 6x - 9)/2 = 9x + 3

AD = CD = 9x + 3

B) To find x, we use the fact that DG is the perpendicular bisector of EC and BG. This means that EG = BG = x.

EG = BG = x

EC = 2EG = 2x

Substituting in EC = 6x - 9, we get:

2x = 6x - 9

4x = 9

x = 9/4 = 2.25

C) To find BC, we use the fact that BC = AB - 2BE

BC = AB - 2BE

BC = 10 - 2(3x + 12)

Substituting in x = 2.25, we get:

BC = 10 - 2(3 * 2.25 + 12)

BC = 10 - 2 * 21

BC = 10 - 42

BC = -32

Answer:

AD = 5, x = 7, BC = 66

Step-by-step explanation:

a) We know that DG is a perpendicular bisector, so it should divide AB into two equal parts, each equal to half the length of the total line segment.
So, AD = AB/2
= 10/2
= 5

b) Now, BE and EC are part of the same segment, as they share a common point E. Also, at E we have perpendicular bisector EG.
Again, the two parts BE and EC should be equal.
Given, BE = 3x + 12 and EC = 6x - 9
3x + 12 = 6x - 9
3x = 21
x = 7

c) Now, BC would be twice the length of one of the segments divided by the perpendicular bisector. So, BC = 2BE
= 2 * (3x + 12)
= 2 (3*7 + 12)
= 2 * 33
= 66

The answer will be option C (3.90 cm).

To find the diameter, we need to determine the exact length reading on the main scale and then add the Vernier scale reading. We know that 10 divisions of the Vernier scale coincide with 9 divisions of the main scale.

If the zero of the Vernier scale lies slightly to the left of 3.2 cm on the main scale, then we can assume that it lies between the 3rd and 4th division of the main scale. Since the 4th division of the Vernier scale coincides with a main scale division, we can determine that the length reading on the main scale is 3.3 cm.

Next, we need to determine the Vernier scale reading. Since the 4th division of the Vernier scale coincides with a main scale division, the reading on the Vernier scale is 0.1 cm. Adding the main scale reading (3.3 cm) and the Vernier scale reading (0.1 cm), we get a total length reading of 3.4 cm.

Since the cylinder is tightly placed between the jaws of the callipers, we can assume that this length reading is equal to the diameter of the cylinder. Therefore, the diameter of the cylinder is 3.4 cm. The answer is closest to option C (3.90 cm).
