A summer resort rents rowboats to customers but does not allow more than four people to a boat. Each boat is designed to hold no more than 800 pounds. Suppose the distribution of adult males who rent boats, including their clothes and gear, is normal with a mean of 190 pounds and standard deviation of 10 pounds. If the weights of individual passengers are independent, what is the probability that a group of four adult male passengers will exceed the acceptable weight limit of 800 pounds?

Answers

Answer 1

Answer:

.023

Explanation:

190 x 4 = 760

New SD is 10 squared x 4 (people) and sqrt all that down to 20

Draw yourself a normal model. What's the P(the combined weights are at least 800 or above) This is an upper tail test.

So you find your z score (if it weren't normal than a t-score for means).

800-760/20 = 2

On your calc... under 2nd vars.....normcdf(2,9^9)

Which gives you .02275 rounded to .023 and that's A for you.

Answer 2

The probability of a group of 4 adult male passengers exceeding the acceptable weight restriction of 800 pounds would be:

- 0.023

Given that,

The maximum number of people to be present in the boat = 4

The maximum weight it can hold = 800 pounds

Mean = 190 pounds

Standard Deviation = 10 pounds

To find,

Probability of a group of 4 adult male passengers exceeding the acceptable weight restriction of 800 pounds = ?

P(∑X ≥ 800) [tex]=[/tex] [tex]1 - P[/tex]((∑X < 800)

[tex]=[/tex] [tex]1 - P[/tex]{(∑X - [tex]n[/tex]μ)/σ[tex]\sqrt{n}[/tex]} < {(800 - 760)/20)}

[tex]=[/tex] [tex]1 - P[/tex][tex](z < 2)[/tex]

= [tex]1 - 0.9772[/tex]

[tex]= 0.023[/tex]

Thus, 0.023 is the correct answer.

Answer:

The young boy (7-year-old son) is compared with his father (40-year-old man), the older man will experience more difficulty in learning the new language.

The 7-year old child has spent little time speaking his native language and can easily learn how to pronounce and speak the new language while the 40 year-old man will experience more difficulty in learning the new language due to number of years has been speaking his own native language.

Thus, we can conclude that when the young boy (7-year-old son) is compared with his father (40-year-old man), the older man will experience more difficulty in learning the new language.

What is the effect of paraquat on ATP, NADPH, and sugar? Paraquat inhibits PSI

Answers

Answer:

ATP increases, and NADPH and sugar decreases

Explanation:

ATP will rise, NADPH will fall, and sugar will decrease as a result of paraquat's action on these molecules. Another name for paraquat is methyl viologen. It is a poisonous substance that is applied as a herbicide to suppress weeds and grass.

What is the impact of paraquat on ATP, NADPH and Sugar?

When paraquat is added to an incubation containing lung microsomes and NADPH, the amount of NADPH oxidized and the amount of oxygen taken in both increase noticeably.

Reactive oxygen species (ROS) produced by paraquat result in lipid peroxidation, NF-B activation, mitochondrial damage, and apoptosis in a variety of tissues.

The quick, dramatic, and protracted oxidation of NADPH caused by paraquat in the lung is thought to trigger compensatory metabolic reactions. This is supported by the biochemical changes' paraquat induces in the lung.

Therefore, ATP will rise, NADPH will fall, and sugar will decrease.

The top of a 25-foot ladder is sliding down a vertical wall at a constant rate of 3 feet per minute. When the top of the ladder is 7 feet from the ground, what is the rate of change of the angle between the bottom of the ladder and the ground?

Answers

I think it’s 8.33 repeating

The rate of change of the angle between the bottom of the ladder and the ground is 10.286 feet per minute.

What is Pythagoras theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

The top of a 25-foot ladder is sliding down a vertical wall at a constant rate of 3 feet per minute.

Let x = distance of the bottom of the ladder from the wall.

And y = distance of the top of the ladder from the ground.

Applying Pythagoras theorem,

x² + y² = 25²   {equation 1}

7² + y² = 25²

y² = 625 - 49

y² = 576

y = √576

y = 24 feet.

The rate of change of the angle between the bottom of the ladder and the ground =

Differentiating the equation 1 with respect to time t.

2x dx/dt + 2y dy/dt = 0

dx/dt = -y dy/dt / x

dx/dt  = (-24) (-3) / 7

dx/dt = 10.286 feet per minute approximately.

Therefore, the rate of change is 10.286 feet per minute.
