The manager of a vacation resort believes that the ages of adult visitors to the resort can be modeled by a normal distribution.

The manager surveyed a random sample of 765 visitors and recorded their age. A summary of the responses is shown in the frequency table, where x represents the age of the visitor. a) Construct a histogram of the distribution of ages. (b) Write a few sentences to describe the distribution of ages of the adult visitors to the resort.

Step-by-step explanation:

(a) A histogram is like a bar graph, but with ranges instead of values.

(b) The distribution is approximately uniform, with slightly more people at the younger and older ends than in the middle.

(c) The ages do not appear to come from a normal distribution.  Normal distributions are bell-shaped, tall in the middle and short on the sides.

Answer:

log_{b}(b^{x r})

Step-by-step explanation:

A picture of the question is shown in the figure attached. There we can see that the step corresponding to Properties of exponents is the option:

log_{b}(b^{x r})

which is equivalent to

While exercising, Carly burns 450 calories per hour biking and 620 calories per hour playing racquetball. Sarah burns 560 calori
Katyanochek1 [597]

Answer:

A

Step-by-step explanation:

30 minutes = half an hour

Carly:

450/2 = 225

620/2= 310

225 + 310 = 535

Carly burned 535 calories total

Sarah:

560/2 = 280

510/2 = 225

280 + 225 = 505

Sarah burned 505 calories total

Carly burned more calories than Sarah

There were 8 judges at a gymnastics competition. Kathleen received these scores for her performance on the uneven parallel bars.
Korolek [52]

Answer:

below

Step-by-step explanation:

mean : 8.8

The mean is the average, so you find it by adding all the numbers together and dividing by n, or how many numbers there are. For this, I added to get 70.4 and divided that by 8 (8 total scores).

70.4/8 = 8.8.

median : 8.85

The median is the middle of the data set, so you put the numbers in increasing order (lowest number to highest number) and then finding the middle of that set. For this set, since there is an even number of numbers (8), you have to find the middle by adding the two middle numbers and dividing by 2.

8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2

The middle numbers are 8.8 and 8.9, so you add those together and divide by 2 to get 8.85.  

mode : 8.9

The mode is just what number appears most often. Because 8.9 appears three times in this data set, more than any other number, the mode is 8.9.

b. The mean reflects a typical score because it is the average, and is used most often when someone is expressing a typical or "average" score. It is the score most people are likely to get, and as there are no outliers in this data set, it reflects a typical score for this data set. It is also the same as the mode, or most often score, in this data set.

Colin drove 45 minutes to the airport. He arrived 90 minutes before his flight departed, and then he spent 70 minutes in the air
Mumz [18]

Answer: The numbers can be added in any order.

Step-by-step explanation:

To calculate the total time that Colin spent traveling from his house to the hotel the numbers can be added in any order because time is a scalar quantity. It cannot be negative.

A scalar quantity is the quantity which has only magnitude but not the directions. For example temperature (vector quantity), it can be both positive and negative but time cannot be negative, thus it is a scalar quantity.

Eileen is trying to test if the function f(x) = x2 + 2x + 5 is even, odd or neither. She produces the following work: f(– x) = (
Elina [12.6K]

Answer:

f(x) is neither even nor odd.

Step-by-step explanation:

For a function to be even f(x) = f(-x)  and  her results show that this is not the case.

For an odd function  -f(x) = f(-x) so we test this:

-f(x) =  -x^2 - 2x - 5 ; f(-x) =  x^2 - 2x + 5  -  so it is not odd.
