The mean cost for the replacement of these brake pads for four different vehicles is equal to $148.75.
What is a mean?A mean can be defined as a terminology that is used to connote a ratio of the sum of the total number of a data set to the frequency of the data set.
How to calculate the mean cost?Mathematically, the mean cost for the replacement of these brake pads for four different vehicles would be calculated as follows:
Mean cost = [120 + 235 + 98 + 142]/4
Mean cost = 595/4
Mean cost = $148.75.

The ratio of hybrid cars to gasoline-powered cars in the parking lot of a local office building is 3:11. if there are 280 cars in the lot and one is to be selected at random to get the reserved parking space nearest the building, find the probability the car selected is a hybrid. express your answer as a fraction.
Answer:
The probability that it will be a hybrid is 21.4%.
Probability is the ratio of number of occurrences to total number of possible occurrences.
Given a total number of 280 cars. The number of hybrid cars is gotten by using the ratio.
Number of hybrid cars = (3/14) * 280 = 60 cars
Probability of picking a hybrid car = Number of hybrid car/total number of cars = 60 cars / 280 cars = 21.4%
Therefore the probability that it will be a hybrid is 21.4%.

Compare the boiling points of 1-pentyne and 1-octyne. compare the vapor pressure curves of 1-butene and 1-heptene. explain your reasoning.
With regards to vapor pressure curves, we can say that 1-butene has higher vapor pressures at lower temperatures than 1-heptene.
How to Interprete Vapour Pressure Curves?
With regards to boiling points, 1-pentyne has a lower boiling point than 1-octyne.
With regards to vapor pressure curves, we can say that 1-butene has higher vapor pressures at lower temperatures than 1-heptene.
Now, these supposed differences in boiling points and vapor pressures arise due to thedifferences in the chain lengths of the molecules.
Larger molecules have stronger intermolecular forces of attraction than smaller molecules. Thus, more energy is required to move larger molecules into the vapor phase from the liquid state.

Intensive care units (icus) generally treat the sickest patients in a hospital. icus are often the most expensive department in a hospital because of the specialized equipment and extensive training required to be an icu doctor or nurse. therefore, it is important to use icus as efficiently as possible in a hospital. according to a large-scale study of elderly icu patients, the average length of stay in the icu is days (critical care medicine journal article). assume that this length of stay in the icu has an exponential distribution. do not round intermediate calculations.
a. Probability that the length of stay in the ICU is one day or less is:0.2614.
b. Probability that the length of stay in the ICU is between two and three days is:0.1426
c. Probability that the length of stay in the ICU is more than five days is:0.2198.
Probability
a. Probabilty of one day or less.
Using this formula
P(X≤1)=1-e^-ux
Since mean is 3.3 the decay parameter is:
u=1/3.3
Hence:
P(X≤1)=1-e^-1/3.3
P(X≤1)=1-e^-0.3030
P(X≤1)=1-0.7385991
P(X≤1)=0.2614
b. Probability of two and three days.
P(X≤2)=1-e^-ux
P(X≤2)=1-e^-2/3.3
P(X≤2)=1-e^-0.60606
P(X≤2)=1-0.54549589
P(X≤2)=0.45450
P(X≤3)=1-e^-ux
P(X≤3)=1-e^-3/3.3
P(X≤3)=1-e^-0.909091
P(X≤3)=1-0.402890
P(X≤3)=0.59711
Hence:
P(2≤X≤3)=0.59711-0.45450
P(2≤X≤3)=0.1426
c. Probability of more than 5 days.
P(X≤5)=e^-ux
P(X≤5)=e^-5/3.3
P(X≤5)=e^-1.515152
P(X≤5)=0.219775
P(X≤5)=0.2198 (Approximately)
Inconclusion the probability that the length of stay in the ICU is one day or less is:0.2614.

Which example shows an interaction between the urinary system and the circulatory system?
The main interaction between the urinary system and the circulatory system is both of the following parts of the human body work for the kidney.
The human body is the collection of many systems like the cardiovascular system for the heart, the urinary system for filtering the body, the circulating system for movement, and so on. All these functions help the body to regulate the smooth functioning of the body.
When the blood enters the kidney through arteries they go through the tiny capillaries that are seen in the urinary system. The blood entered into the kidney later moves to nephrons, where the blood is purified with the help of filters.
The waste that is obtained after the purification of the blood is then transferred to the vital substance that absorbs the bloodstream. It helps the body to manage and control the level of pressure in the blood.
Here the job of the heart is to simultaneously send the oxygenated blood all around the body and send the unwanted, discharged waste to the kidney where it helps to observe the required elements from the waste and transpose it to the urinary system.
The main work of the circulating system is to transpose the oxygenated blood to every part of the cell and provide them with sufficient nutrients.
From this system it is understandable that the similarities between circulatory and urinary system is both of the parts functions to remove waste from the body.
