Based on the given data, the box plot that represents the temperature recordings in Mr. Jensen's science class for two weeks is the first box plot: Temperature (°F) 54 52 56 58 62 60. This box plot visually displays the distribution and range of the recorded temperatures.

In this box plot, the minimum temperature recorded is 52°F, the lower quartile is 54°F, the median is 56°F, the upper quartile is 58°F, and the maximum temperature is 62°F. The box itself represents the interquartile range (IQR), which shows the spread of the middle 50% of the data. The whiskers extend from the minimum to the maximum values, and any data points beyond the whiskers are considered outliers.

By examining the box plot, we can observe that the majority of temperatures fall within the range of 54°F to 58°F, as indicated by the box. The median of 56°F represents the middle value of the data set, dividing it into two equal halves. The whiskers show that there are no outliers present in the data.

Answer:

x = 38.7

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opposite/ adjacent

tan x = 8/10

Take the inverse tan of each side

tan ^-1 ( tan x) = tan ^-1 (8/10)

x = tan ^-1 (8/10)

x =38.65980825

To the nearest tenth

x = 38.7

The probability of drawing a pair when selecting three cards at random from a standard 52-card deck is approximately 0.1694, or about 16.94%.

To calculate the probability of drawing a pair of cards from a standard 52-card deck when selecting three cards at random, we need to consider the number of favorable outcomes (pairs) and the total number of possible outcomes.

First, let's determine the number of favorable outcomes. For a pair, we need two cards of the same rank (e.g., two 7s, two Queens, etc.) and any third card that is different from the pair.

The number of ways to choose a rank for the pair is 13 (one for each rank). For each rank, there are four cards of that rank in the deck. Therefore, the number of ways to select two cards of the same rank is given by:

Number of ways to choose a pair = 13 * (4 choose 2) = 13 * 6 = 78

After selecting the pair, there are 50 cards remaining in the deck. The third card must be of a different rank from the pair. There are 48 cards remaining with different ranks from the pair.

Therefore, the number of favorable outcomes (pairs) is 78 * 48 = 3,744.

Next, let's calculate the total number of possible outcomes when selecting three cards from a standard deck. The total number of ways to choose any three cards from 52 cards is given by:

Total number of possible outcomes = (52 choose 3) = 22,100

Finally, we can calculate the probability of drawing a pair:

Probability of drawing a pair = Number of favorable outcomes / Total number of possible outcomes

= 3,744 / 22,100

≈ 0.1694

Therefore, the probability of drawing a pair when selecting three cards at random from a standard 52-card deck is approximately 0.1694, or about 16.94%.

Answer:

The length of the arc travelled by the swing is approximately 3.77 m  

Step-by-step explanation:

The given parameters of the swing are;

The swing base height of the swing above the ground = 72 cm

The swing base height above the when the swing travels an angle of 60° = 252 cm

Therefore we have;

r × cos(60°) = r - 180

180 = r - r × cos(60°)

r = 180/(1 - cos(60°)) = 360

r = 360 cm

The length of the arc travelled by the swing in meters, \(l_{arc}\) is given as follows;

\(l_{arc} = \dfrac{\theta}{360 ^{\circ}} \times \pi \times 2\times r\)

Therefore;

\(l_{arc} = \dfrac{60^{\circ}}{360 ^{\circ}} \times \pi \times 2\times360 = \dfrac{1}{6} \times \pi \times 720 = 120 \cdot \pi\)

The length of the arc travelled by the swing, \(l_{arc}\) = 120·π cm

∴ The length of the arc travelled by the swing, \(l_{arc}\) = 1.2·π m ≈ 3.77 m

If there are 20 blondes in a class, 25 Brunettes, and 5 Redheads in a class, the proportion of the class that is blonde is 0.40 and the probability that someone in the class in blonde is 0.60.

There are 50 people in the class

There proportion is given by:

20/50, 25/50, 5/50: 40%, 50%, 10%

0.40 is blonde and 0.60 probability

Probability represents the chances of some event happening. It is theoretical. Proportion summarizes how frequently some event actually happened. Let us consider an example:

If we flip a fair coin, the probability that it will land on heads is 0.5 or 50%.

However, if we flip a fair coin 20 times then we can actually count the proportion of times it landed on heads. For example, perhaps it landed on heads in 60% of the flips.

The probability of landing on heads is theoretical, but the proportion of times the coin landed on heads is empirical – we could actually count the proportion.

So, on solving the provided question, we can say that percentage  = 1/15 X 100 = 15%

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Answer:

Option C is the correct answer.

C.  5•(-20)

Step-by-step explanation:

We are told that the insurance payment for the car follows a certain pattern that can be represented through an expression. The payment is decreasing by $20 every year. As we don't know the total payment amount per period, so we cannot calculate how much is paid per period/year for insurance but we can calculate the rate at which this payment is decreasing.

Change in payment = t * (-20)

The above expressions can be used to calculate the amount of change in payment i payment is decreasing by a constant $20 every year, after t years.

So, if we want to calculate the change in payment after say 5 years, we can replace t with 5 in the equation and calculate the change,

Change in payment = 5 * (-20)

Change in payment = - $100

The domain and range of the inverse relation are {2, 3, 5, 7, 8} for both.

The given relation consists of the points 2, 3, 5, 7, and 8. To find the domain and range of the inverse relation, we need to swap the x-values with the y-values. The resulting set of values will represent the domain and range of the inverse relation.

In the given relation, the x-values are 2, 3, 5, 7, and 8, and the corresponding y-values are not provided. To find the inverse relation, we swap the x-values with the y-values.
After swapping the values, we obtain the following set of points: (2, 2), (3, 3), (5, 5), (7, 7), and (8, 8). These points represent the inverse relation.
The domain of the inverse relation is the set of x-values from the swapped points, which is {2, 3, 5, 7, 8}. This means that these are the values for which there exist corresponding y-values in the original relation.
Similarly, the range of the inverse relation is the set of y-values from the swapped points, which is also {2, 3, 5, 7, 8}. These are the values that correspond to the x-values in the original relation.
Therefore, the domain and range of the inverse relation are {2, 3, 5, 7, 8} for both.

1                           185

2                           140

4                                50

5                            5

To complete the table for John's drive, we need to substitute different values of x into the equation y = 230 - 45x to calculate the corresponding distances from Surt (y) at different times (x).

In this table, the time (x) represents the number of hours John has been driving, and the distance from Surt (y) represents the corresponding distance he has covered from Surt in miles.

For example, when John starts driving (x = 0), he is 230 miles away from Surt. As time progresses, the distance from Surt decreases by 45 miles for every hour of driving, according to the equation y = 230 - 45x.

By substituting different values of x into the equation, we can determine the distance from Surt at various points in John's drive.

The volume of plaster Darla needs for the miniature stairs is 418³.

The volume is the space occupied by a three-dimensional object.

Volume is the product of the multiplication of length, width, and height.

We first calculate the total volume for this situation, assuming that the stairs have not cut portions.

Secondly, calculate the volume of the cut portions and subtract the result from the total volume to get the volume of the stairs, which represents the quantity of plaster required by Darla.

Length of the miniature stairs = 12 cm

Width of the miniature stairs = 11 cm

Height of the miniature stairs = 4 cm

The volume of the stairs with the cut portion = 528 cm³ (12 x 11 x 4)

The length of the cut portion of the stairs = 12 cm

The width of the cut portion of the stairs = 11 cm

The height of the cut portion of the stairs = 2 cm (4 - 2)

The volume of the cut portion of the stairs = 110 cm³ (11 x 5 x 2)

The volume of the stairs without the cut portion = 418 cm³ (528 - 120)

The total volume of plaster can also be computed separately as the volume of the larger object plus the volume of the smaller object.

418 cm³= (7 cm x 4 cm x 11 cm) + (5 cm x 2 cm x 11 cm)

= (308 cm³ + 110 cm³)

Thus, the quantity (volume) of plaster Darla needs is 418 cm³.
