Answer:

B. 0.602%

Step-by-step explanation:

Probability is essentially (# times specific event will occur) / (# times general event will occur). Here, we have a few specific events: draw a quarter, draw a second quarter, draw a penny, and draw another penny. The general event will just be the number of coins there are to choose from.

The probability that the first draw is a quarter will be 4 / (4 + 8 + 9) = 4/21.

Since we've drawn one now, there's only 21 - 1 = 20 total coins left. The probability of drawing a second quarter is: (4 - 1) / (21 - 1) = 3/20.

The probability of drawing a penny is: 9 / (20 - 1) = 9/19.

The probability of drawing a second penny is: (9 - 1) / (19 - 1) = 8/18.

Multiply these four probabilities together:

(4/21) * (3/20) * (9/19) * (8/18) = 864 / 143640 ≈ 0.602%

The answer is B.

Answer:

0.602%

Answer:

The MAD is: 2

Step-by-step explanation:

First, you add all the terms together. So we get 49.

Then, we divide 49 by the amount of terms. There are 7 terms, so we do 49/7.

We get 7. Now we have to find out the distance between each point and the mean, which is seven.

Now, we add all the distances together. We get 14.

Now, we divide 14 by the amount of terms, which is 7. 14/7 is 2.

The answer is b.

The correct option is b. The mean absolute deviation of the data set is 2.

To find the mean absolute deviation (MAD) of the data set [tex]\(\{8, 5, 12, 4, 5, 8, 7\}\)[/tex], follow these steps:

1. Calculate the mean (average) of the data set.

[tex]\text{Mean} = \frac{\sum \text{data points}}{\text{number of data points}} \\\\\text{Mean} = \frac{8 + 5 + 12 + 4 + 5 + 8 + 7}{7} = \frac{49}{7} = 7[/tex]

2. Find the absolute deviations from the mean for each data point.

[tex]|8 - 7| &= 1 \\|5 - 7| &= 2 \\|12 - 7| &= 5 \\|4 - 7| &= 3 \\|5 - 7| &= 2 \\|8 - 7| &= 1 \\|7 - 7| &= 0 \\[/tex]

3. Calculate the mean of these absolute deviations.

[tex]\text{Mean Absolute Deviation} = \frac{\sum \text{absolute deviations}}{\text{number of data points}} \\\\\text{Mean Absolute Deviation} = \frac{1 + 2 + 5 + 3 + 2 + 1 + 0}{7} = \frac{14}{7} = 2[/tex]

So, the mean absolute deviation of the data set is: b. 2

Answer:

2137 kg

Step-by-step explanation:

The number of fish the fisherman harvest in the first five days is

512 kg.

Given,

A fisherman harvested 350 kg of fish on Monday.

From Monday to Friday, the amount of fishes, be harvested increased by

10% per day.

We need to find the total amount of fish the fisherman harvest in the

first five days.

Round your answer to the nearest whole number.

We multiply the required percentage with the given amount.

Example:

10% of 500 = 10/100 x 500 = 10 x 5 = 50

We have,

Each day 10% increases.

Monday:

350 kg of fishes

Tuesday:

350 x 10%

= 350 x 10/100

=350 x 1/10

= 35

The number of fishes:

= 350 + 35

= 385 kg

Wednesday:

385 x 10%

= 385 x 1/10

= 38.5

The number of fishes:

= 385 + 38.5

= 423.5 kg

Thursday:

423.5 x 10%

= 423.5 x 1/10

= 42.35

The number of fishes:

= 423.5 + 42.35

= 465.85 kg

Friday:

465.85 x 10%

= 465.85 x 1/10

= 46.585

The number of fishes:

= 465.85 + 46.585

= 512.435 kg

Rounding to the nearest whole number we get,

= 512 kg

Thus the number of fish the fisherman harvest in the first five days is

512 kg.

Answer:

The perimeter of the quarter-circle is 200 cm.

Step-by-step explanation:

Given that the angle of quarter-circle is 90°. So using Length of Arc formula, you are able to find the length of curve :

[tex]arc = \frac{θ}{360} \times 2 \: \pi \: r[/tex]

Let r be radius = 56 cm,

Let θ = 90°

[tex]arc = \frac{90}{360} \times 2 \times\pi \times 56[/tex]

[tex] = \frac{1}{4} \times 2 \times \pi \times 56[/tex]

[tex] = \frac{1}{2} \times \pi \times 56[/tex]

[tex] = 28\pi \: cm[/tex]

We have already found the arc. Next we have to add up together to find the perimeter :

[tex]p = 56 + 56 + 28\pi[/tex]

[tex]p = 112 + 28\pi[/tex]

[tex]p = 200 \: cm \: (3s.f)[/tex]

Answer:

Option "A" is the correct answer to the following question.

Step-by-step explanation:

Complementary angles ⇒ If the sum of two angles becomes 90 degrees, we can say that this is a complementary pair of angles.

In the given situation angle ∠RST and ∠TSU are a pair of complementary angles.

∠RST + ∠TSU = 90° (Complementary angles)

So, we say that the option "A" is the correct answer.

The correct statement is Option A) m∠RST + m∠TSU = 90°

To determine which statement is true for two complementary angles ∠RST and ∠TSU, we need to understand the definition of complementary angles in geometry.

Complementary angles are two angles whose measures add up to 90 degrees. Therefore, the correct option is:

A) m∠RST + m∠TSU = 90°

This is because, by definition, if two angles are complementary, their measures always sum up to 90 degrees. For instance, if m∠RST is 30 degrees, then m∠TSU must be 60 degrees so that their sum is 90 degrees.

Answer:

Yes. parallel lines are known to have the same slope, but perpendicular lines will always have negative-reciprocal slopes.

This holds true for all lines that are not vertical or horizontal

This holds true for all lines that are not vertical or horizontal. A horizontal line has a slope of 0, and a vertical line has an undefined slope. These lines are perpendicular, but the rule of negative reciprocals does not apply because you cannot divide by zero.

Let’s prove that the product of the slopes of two perpendicular lines is -1.

Let’s consider two lines, Line 1 and Line 2, that are perpendicular to each other.

Line 1: Let’s say the slope of Line 1 is m1.

Line 2: Now, let’s consider Line 2 which is perpendicular to Line 1. Let’s say the slope of Line 2 is m2.

Since Line 1 and Line 2 are perpendicular, the angle between them is 90 degrees. Now, the tangent of the angle between two lines is equal to the absolute difference of their slopes divided by 1 plus the product of their slopes.

tan(90) = |m1 - m2| / (1 + m1*m2)

But we know that tan(90) is undefined, which implies that the denominator of the right side of the equation must be zero.

So, 1 + m1*m2 = 0, which implies that m1*m2 = -1.

Therefore, we have proved that the product of the slopes of two perpendicular lines is -1.

Using trigonometry and the tangent function, the height of the taller building, with a 42˚ angle of elevation from the smaller 32-foot building 35 feet away, is calculated to be approximately 63.514 feet. The formula tan(42˚) = (h₂ - 32) / 35 is utilized where tan(42˚) ≈ 0.9004. Solving this equation gives the height of the taller building.

The question asks: Two buildings are 35 feet apart. The elevation angle from the top of the smaller building to the top of the taller building is 42˚. The smaller building is 32 feet high. Find the height of the taller building.

To solve this problem, we will use trigonometry, specifically the tangent function, which relates an angle of a right triangle to the ratio of the opposite side to the adjacent side.

Let's denote the height of the smaller building as h₁ = 32 feet, the height of the taller building as h₂, and the horizontal distance between the buildings as 35 feet. The elevation angle from the top of the smaller building to the top of the taller building is 42˚.

First, we determine the difference in height (Δh) between the two buildings:

→ tan(θ) = opposite/adjacent

In this case:

→ tan(42˚) = (h₂ - h₁) / 35

We solve for the height difference:

→ (h₂- 32) = tan(42˚) * 35

Using a calculator to find tan(42˚):

→ tan(42˚) ≈ 0.9004

Substituting the value:

→ (h₂ - 32) = 0.9004 * 35

→ h₂ - 32 ≈ 31.514

Adding 32 to both sides:

→ h₂ ≈ 31.514 + 32

→ h₂ ≈ 63.514

Therefore, the height of the taller building is approximately 63.514 feet.

Answer:

I'm positive that the

answer is B 8

Answer: C

Step-by-step explanation:

Alright, first let’s review what compound interest is. Instead of simple interest which pays interest on the principal, it pays interest on the amount in the bank each year, so it basically pays interest on the principal with previous interest. Lets run this example through the years:

Year 1:

= $1800 + 5% (Of 1800)

= $1800 + $90

= $1890

Year 2:

= $1890 + 5% (of 1890)

= $1890 + $94.5

= $1984.50

Year 3:

= $1984.50 + 5% (of 1984.50)

= $1984.50 + $99.23 (I rounded it to the nearest hundredth from its original state, $99.225)

= $2083.73

Year 4:

= $2083.73 + 5% (of 2083.725)

= $2083.73+ $104.19 (I rounded it to the nearest hundredth from its original state, $104.1865)

= $2187.92

Year 5:

= $2187.92 + 5% (of $2187.92)

= $2187.92 + $109.40 (rounded to the nearest hundredth from 109.396)

= $2297.32

This is as close as you can get to answer C, it’s just off one cent because of all the rounding!

Step-by-step explanation:

his per pound is 75 cents

Ed charges $3.75 for 5 pounds of cabbage, which makes his unit rate $0.75 per pound. To compare his unit rate with other farmers, calculate each of their unit rates and compare them to Ed's. Farmers work with a "going rate" like most agricultural markets, which reflects the competitive nature of the industry.

To determine whether the unit rate charged for cabbage by other farmers is less than, equal to, or greater than the unit rate charged by Ed, it is necessary to calculate Ed's unit rate first. Ed charges $3.75 for 5 pounds of cabbage, which means the unit rate is $3.75 ÷ 5 pounds = $0.75 per pound.

Once we have Ed's unit rate, we can compare it with the rates provided by other farmers. Without the rates from other farmers included in the question, the specific comparison cannot be completed. However, if another farmer is charging a different price for a quantity of cabbage, you would calculate their unit rate the same way and compare it to Ed's $0.75 per pound. If the unit rate of another farmer is less than $0.75, then they charge less than Ed. If it is greater than $0.75, they charge more than Ed. If it is equal to $0.75, then they charge the same as Ed.

Understanding unit rates is crucial as it helps consumers make informed decisions and ensures that farmers like Ed maintain competitiveness within the market, similar to the conditions agricultural growers face. Farmers generally adhere to a "going rate", which represents a price point that is influenced by supply and demand within a competitive market.

Explanation:

For now, focus solely on the orange boxplot. The first quartile Q1 is the left edge of the box, which is at 3.5; while the value of Q3 is 7.5 (right edge of the box). The interquarile range (IQR) is ...

IQR = Q3 - Q1

IQR = 7.5 - 3.5

IQR = 4

This is basically the width of the box. Ignore the whiskers when it comes to the IQR.

Let A = 4 as we'll use it later.

---------------------------------

Find the IQR for the blue box plot

Q1 = 6 = left edge of the blue box

Q3 = 9.5 = right edge of the blue box

IQR = Q3 - Q1

IQR = 9.5 - 6

IQR = 3.5

Let B = 3.5 as we'll use it later

---------------------------------

Subtract the values of A and B to find the difference of the IQR values

A - B = 4 - 3.5 = 0.5
