Exercise 2.2 gave the following data (in increasing order) for the attribute age: 13, 15, 16, 16, 19, 20, 20, 21, 22, 22, 25, 25

Response:

1 B

2 A

3 B

Detailed explanation:

1

The population refers to the entire sample from which part of the event is being analyzed. Essentially, in a set, the population includes everything collectively. From the provided statement, our goal is to identify the population. The population is B.

All NBA players since 1966. This selection is because it is from this set that the draft picks were chosen, ultimately narrowed down to 45% being center backs.

2

The specified attribute is A.

Being a No. 1 draft pick, as it's the central focus of the statement itself

3

B sample proportion. As mentioned earlier, the population consists of all NBA players since 1966, so a population proportion would contain a statement like this.

45% of all NBA players since 1966...

Consequently, it's a sample proportion since it pertains to the draft pick, as opposed to the NBA players

Answer:

The transformation is a reflection over the x-axis followed by a translation 6 units left and 2 units down.

Step-by-step explanation:

To determine the order of transformations from ΔABC to ΔA"B"C", note that the figure first changes to ΔA'B'C', and then to ΔA''B''C''.

The transition from ΔABC to ΔA'B'C' involves a reflection over the x-axis, as ΔA'B'C' appears as a mirror image flipped vertically.

Next, moving from ΔA'B'C' to ΔA''B''C'' entails shifting the figure left by 6 units and downward by 2 units. This matches a translation by -6 in the x direction and -2 in the y direction.

Thus, the accurate description is:

Reflection across the x-axis followed by a translation of -6 units in x and -2 units in y.

Answer: A total descent of 8260 feet occurred for all four balloons.

Step-by-step explanation:

Based on the information provided:

Number of hot air balloons = 4

Minutes of descent = 7

Descent rate per minute = 295 feet

Thus, the overall change in altitude for all four balloons can be calculated as:

Thus, a total descent of 8260 feet was experienced by the four balloons.

Let's start by calculating the cost of the first 10 boxes, which totals $75, and the next 10 boxes cost $55.

Together, these 20 boxes amount to $130 spent. With $18 remaining, you can purchase 4 more boxes since 18 divided by 4.5 equals 4.

Therefore, the maximum number of boxes you can buy with $148 is 24.

Response:

$3,000

Detailed breakdown:

This scenario is centered around compound interest, with the formula for compound interest defined as

Provided Data

A = final amount  =?

P = initial principal balance  = $2,500

r = interest rate = 2.1%= 0.021

t = number of time units passed= 14 years

By inserting our data into the compound interest equation, we can determine the final amount

Therefore, rounding to the nearest hundred gives us an account balance of $3,000
