In a 5000 m race on a 400 m track, each athlete must run 12 Â½ laps. kara runs the race at a constant pace and finishes in 17.5 min, while hannah runs at a faster pace and finishes 15.3 min. in fact, hannah ran fast enough that she passed kara during the race. how many laps had hannah run when she caught and passed kara?

Answers

Hannah had run 6 complete laps and is running the 7th lap when she surpasses the athlete Kara.

Who is an athlete?

An athlete (sometimes known as a sportsman or sportswoman) is a person who participates in one or more sports that require physical stamina, speed, or strength.

Professional and amateur athletes both exist. The majority of elite athletes have extremely well-developed bodies because to rigorous physical training, stringent exercise, and a tight food regimen.

Isotonic exercisers had a greater mean left ventricular end-diastolic capacity and are less prone to experience depression. Athletes are far more prone than the general public to go to massage parlors and pay for the services of massotherapists and masseurs due to their demanding physical activity. Athletes whose sport favors endurance over strength typically consume less calories than other athletes.

Calculations:

Total length of the race (L) = 5000 m

Time taken by Kara (tk) = 17.9 min = 1074 s

Kara's speed (vk) = L/tk = 5000/1074 m/s

Time taken by Hannah (th) = 15.3 min = 918 s

Hannah's speed (vh) = L/th = 5000/918 m/s

Let the number of laps Hannah had run when she passes Kara be n

Distance travelled by Hannah in this time = n*400 = 400n meters

Time taken by Hannah to run n laps = 400n/(5000/918)=367200n/5000=73.44n

Distance travelled by Kara in this time = (n-1)*400 = 400n - 400 meters

Time taken by Kara to run (n-1) laps = (400n-400)/(5000*1074)=(429600n-429600)/5000=85.92n-85.92

= 85.92n - 85.92 = 73.44n

= 12.48n = 85.92

= n = 6.88

An automobile purchased for $37000 is worth $2600 after eight
years. Assuming that the value decreased steadily each year,
what was the car worth at the end of the fifth year?

Answers

The car has a value of $ 15 500 at the end of the fifth year.

What is the value of a car in time?

In accordance with the statement, the value of an automobile decreases in time and decreases steadily. A stead decrease means that the value decreases linearly in time, whose formula is shown below:

C' = C + r · t (1)

Where:

C - Initial value of the car, in dollars.C' - Final value of the car, in dollars.r - Decrease rate, in dollars per time.t - Time.

If we know that C = $ 2 600, C' = $ 37 000 and t = 8, then the value of the car at the end of the fifth is:

r = (C' - C) / t

r = (2 600 - 37 000) / 8

r = - 4 300

t = 5

y = 37 000 - 4 300 · 5

y = 15 500

The car has a value of $ 15 500 at the end of the fifth year.

Answers

Relationships that have a uniform or constant rate are said to be proportional relationships. Because it does not employ a uniform rate, the price of food does not follow a proportional connection.

The missing table looks like this:

Bag cost

0 0

5 17.5

30 89

First, we calculate the slope (m) of the table using:

(x₁ y₁) = (0,0)

(x₂ y₂) = (5,17.5)

m₁=(y₂-y₁)/(x₂ -x₁)

m₁=(17.5-0)/(5-0)

m₁=3.5

The slope for the following points

(x₁ y₁) = (0,0)

(x₂ y₂) = (30,89)

m₂=(y₂-y₁)/(x₂ -x₁)

m₂=(89-0)/(30-0)

m₂=2.97

3.5 ≠2.97

Hence, the cost of food is not a proportional relationship because it does not use a uniform rate.

A study was performed with a random sample of 513 bolts produced at one factory. What population would be appropriate for generalizing conclusions from the study, assuming the data collection methods used did not introduce biases?.

Answers

Given that the study was conducted using a sample of 513 bolts produced at a single facility when there is no bias resulting from data gathering procedures, broad inferences may then be drawn.

All bolts manufactured by that factory would be covered by the conclusion?

Due to the fact that bolts made in the same factory will follow the results of an analysis of a sample made up of bolts from the same factory. The finding or conclusion would therefore be applicable to all bolts produced in the same factory because the environment for experimentation and production is the same there while it may differ in other factories. Conclusions from the study may not apply to the bolts made by other companies as a result of this bias.

Answers

278 is the value of IQR.

What do we mean by IQR?The interquartile range (IQR) is a way of measuring statistical dispersion, or the spread of data, in descriptive statistics. The IQR is also known as the midspread, the middle 50%, the fourth spread, or the Spread. It is defined as the difference between the data's 75th and 25th percentiles. To calculate the interquartile range (IQR), first, compute the median (middle value) of the data's lower and upper halves. These are quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The IQR is the distinction between quarters three and one.

To find the IQR:

Arrange in ascending order as follows:

311, 402, 410, 470, 478, 525, 541, 582, 688, 709, 904

The middle value or the median is 525.

IOR = Q₃ - Q₁

Q₁ from the lower half is 410 and Q₃ from the upper half is 688.

So, IOR = 688 - 410 = 278

Therefore, the value of IQR is 278.

13. Measuring bone density Individuals with low bone
density have a high risk of broken bones (fractures).
Physicians who are concerned about low bone density
(osteoporosis) in patients can refer them for special-
ized testing. Currently, the most common method for
testing bone density is dual-energy X-ray absorptiom-
etry (DEXA). A patient who undergoes a DEXA test
usually gets bone density results in grams per square
centimeter (g/cm²) and in standardized units.
7.
Judy, who is 25 years old, has her bone density
measured using DEXA. Her results indicate a bone
density in the hip of 948 g/cm² and a standardized
score of z = -1.45. In the reference population of
25-year-olet women like Judy, the mean bone density
in the hip is 956 g/cm².6
(b) Use the information provided to calculate the standard
deviation of bone density in the reference population.

Answers

Using the normal distribution, the standard deviation of bone density in the reference population is of 5.52 g/cm².

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

For this problem, the parameters are given as follows:

[tex]X = 948, z = -1.45, \mu = 956[/tex]

Hence we solve for [tex]\sigma[/tex] to find the z-score as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.45 = \frac{948 - 956}{\sigma}[/tex]

[tex]-1.45\sigma = -8[/tex]

[tex]\sigma = \frac{8}{1.45}[/tex]

[tex]\sigma = 5.52[/tex]

The standard deviation of bone density in the reference population is of 5.52 g/cm².

To find: All the sides of the triangular lot.

FInding:

Let the shortest side of the triangular lot be 'x'.

Then, according to the question, one side of the triangular lot = 100 + x and other = 300 + x

As perimeter of a triangle = sum of all the sides,

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. the curve at the top is more dispersed and has a greater standard deviation than the curve at the bottom, which is more concentrated around the mean and has a lower standard deviation.
