About how many times more likely is a 17-year-old driver to crash with three passengers than with one passenger? about twice as likely about three times as likely about four times as likely about five times as likely

Answers

Answer:

A. twice as likely

Explanation:

right on Edge.

About three times as likely is a 17-year-old driver to crash with three passengers than with one passenger.

Research studies have shown that the presence of passengers in a vehicle can increase the risk of crashes for young and inexperienced drivers. A 17-year-old driver is generally more likely to be involved in a crash when there are multiple passengers in the car compared to having just one passenger.

While the exact increase in risk may vary depending on various factors, it is commonly estimated that the risk of crashing with three passengers is approximately three times higher than with one passenger. This highlights the importance of considering passenger-related distractions and managing the number of passengers in a vehicle, especially for newly licensed teenage drivers.

prove that 2sin A/cos 3A + 2 sin3A/cos 9A +2sin9A/cos27A = tan 27A-tanA​

Answers

Answer:

2 sin A / cos 3A + 2 sin 3A / cos 9A + 2 sin 9A / cos 27A = tan 27A - tan A

2 sin A/cos 3A

Multiply with cos A to Numerator and denominator

= 2 sin A cos A/cos 3A cos A 

Formula (sin 2A = 2 sin A cos A)

= sin 2A / cos 3A cos A 

Formula [ (sin a-b) / cos a cos b = tan a - tan b ]

So, 

= sin 3A - A / cos 3A cos A

= tan 3A - tan A----> Equation 1

Apply same procedure we get

2 sin3A / cos 9A = tan 9A - tan 3A---> Equation 2

2 sin 9A / cos 27A = tan 27A - tan 9A----> Equation 3

Add Equation 1,2 and 3

tan 3A - tan A + tan 9A - tan 3A + tan 27A - tan 9A = tan 27A - tan A

2 sin A / cos 3A + 2 sin 3A / cos 9A + 2 sin 9A / cos 27A = tan 27A - tan A

O Only emptying when it is completely full.
O Noting the brand of ostomy bag that is used.
Checking the condition of the skin around the stoma.

Answers

The correct answer is D. Checking the condition of the skin around the stoma.

Explanation

The ostomy is a surgical procedure in which a hole is made in the abdomen to remove the digestive or urinary tract, with the aim that the waste from the body is expelled into a bag for collection.

This surgical intervention is performed on patients who have altered digestive or urinary function due to different causes (mainly cancer or inflammatory bowel diseases).

When disposing of a disposable ostomy bag it is necessary to take the following factors into account: Hygiene should be done with water and neutral soap, with a soft sponge. In addition, the condition of the skin around the stoma must be taken into account, taking into account that it must be pink or red and be moist in a normal state. If it shows another color or smell, it is advisable to visit the doctor.

On the other hand, some factors do not affect in any way the change of the osteoma bag, such as having the help of the family, since this process can be carried out only by the patient, emptying only when it is full because it is You can empty earlier if required, and observe the brand of ostomy bag being used, as this does not mean any major change from this treatment, as long as special bags are used for this procedure. According to the above, the correct answer is D.

Women of childbearing age are more likely to develop autoimmune diseases than men of a similar age. Please select the best answer from the choices provided. T F

Answer:

true :)

Explanation:

Ed 2022

Women have two X chromosome genes, while men have one, hence they are more likely to acquire autoimmune illnesses due to the higher mutation rate.

What is autoimmune disease?

An autoimmune disease is one in which the body's natural defense mechanism is unable to differentiate between its own cells and those of other organisms, leading to the inappropriate destruction of healthy cells by the immune system. There are about 80 different forms of autoimmune illnesses, and they can manifest themselves in a wide variety of ways across the body.

Because women have a greater number of genes that originate from the X chromosome than men do (women have two, while men only have one), there is a much greater possibility that a larger number of mutations will take place. This puts women at a greater risk for the development of autoimmune diseases than men do.

One, his shop wouldn't fit in our basement, and two, there was no way the lathe, weighing fifteen hundred pounds, and the milling machine, weighing two thousand pounds, could be carried into the basement.
