The probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 is approx b). 0.9428.

The intelligence quotient (IQ) test scores for adults are normally distributed with a population mean of 100 and a population standard deviation of 15. The standard deviation of the mean of a sample of 50 adults can be calculated as the population standard deviation divided by the square root of the sample size, or 15/√50 = 1.58.

Using a standard normal distribution table, the probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 can be calculated as the area under the standard normal curve between the z-scores corresponding to 98 and 103. These z-scores can be calculated using the formula z = (x - mean) / standard deviation, where x is the value of interest and mean is the population mean. The z-score for 98 is (98 - 100) / 1.58 = -1.27, and the z-score for 103 is (103 - 100) / 1.58 = 2.53.

The area under the standard normal curve between -1.27 and 2.53 can be found using a standard normal distribution table or a calculator with normal distribution functions. The probability of selecting a sample of 50 adults and finding that the mean of this sample is between 98 and 103 is approximately 0.9228, which is closest to the answer choice b. 0.9428.

Elisabeth needs 253 hours and 64/100 of an hour to read 34 books, which is stated as a mixed number in the simplest form as 253 3/5 hours.

In order to calculate the amount of time it takes Elisabeth to read 34 books, we need to calculate the amount of time it takes her to read 1 book first.

Since she reads 15 books in 112 hours, we can divide 112 by 15 to find the amount of time it takes her to read 1 book.

112 / 15 = 7.46

This means that it takes Elisabeth 7.46 hours to read 1 book.

Now we can multiply 7.46 by 34 to find the amount of time it takes her to read 34 books.

7.46 x 34 = 253.64

This means it takes Elisabeth 253.64 hours to read 34 books. Since this is a mixed number, we can convert it to its simplest form by subtracting the whole number from the decimal number and expressing it as a fraction.

253.64 - 253 = 0.64

Therefore, it takes Elisabeth 253 hours and 64/100 of an hour to read 34 books, which can be expressed as a mixed number in simplest form as 253 3/5 hours.

To find the time it took Clare to ride 10 miles, we can use the concept of speed, which is defined as distance divided by time. In this case, Clare's constant speed was 15 miles in 72 minutes, so her speed is 15/72 miles per minute.

Using this speed, we can calculate the time it took her to ride 10 miles by dividing the distance by the speed:

Time = Distance / Speed

Time = 10 miles / (15/72 miles per minute)

Time = 10 * 72 / 15 minutes

Time = 43.2 minutes

So, it took Clare approximately 43.2 minutes to ride 10 miles at her constant speed of 15 miles in 72 minutes.

The slope intercept form of an equation is y=-40x+140.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

From the given graph the coordinate points are (2, 100) and (1, 140).

Here, slope(m) = (140-100)/(1-2)

m= -40

Substitute m= -40 and (x, y)=(2, 100) in y=mx+c, we get

100=-40(1)+c

c=140

Substitute m= -40 and c=140 in y=mx+c, we get

y=-40x+140

y = x + 2 is the  other equation if its graph has a slope of 1.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

If the y-coordinate of the intersection point of the two equations is 2, and one of the equations is y = 3x + 5,

The other equation must be of the form y = mx + b, where m is the slope of the line and b is the y-intercept.

m=1 is the slope of the other equation.

y = mx + b

2 = 1x + b

b = 2 - 1x

b = 2 - x

In 5 years, the town will have 7,359 people living there.

Next, we can set up the exponential equation, using the initial population of 6,348 and the growth rate of 1.013:

P(t) = 6348 *[tex]1.013^t[/tex]

where t is the time since the initial population was formed. t is 5 in this instance. We can now incorporate this into the equation to determine the town's population after five years:
