Answer:

Approximately 53.9%

To be exact, answer is 48700/903

Step-by-step explanation:

Percentage of men = Men ➗ Total population

48700 + 41600 = 90300

48700/90300 is approximately 0.539

0.539 * 100 = 53.9

Answer:

53.931339977852% (you can round)

Step-by-step explanation:

You add up 48,700 and 41,600 and you would get 90,300 as the overall population. Then you would put it in fraction form if you want to convert it into a percentage. The fraction form would be 48,700/90,300. You could simplify it to 487/903. Then you do 487 x . You would cross multiply and get

___ = ___

903 100

903x = 48700. Then you would divide each side by 903 and get x = 53.931339977852% (you can round)

Answer:

e = 7.5

Step-by-step explanation:

Hi,

15 = e/0.5

You need to find what e equals. To do that, you need e all by itself. So to get e by itself in this equation, you need to multiply by 1/2 (same thing as 0.5). 15 x 0.5 is equal to 7.5.

To check your work, 7.5/0.5 is equal to 15.

So you know it's correct.

I hope this helps you :)

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for

RSB [31]

L (water level) = -0.5 d (days) +34

Place 26 into the (L) variable and solve

26= -0.5 d + 34

0.5 d = 8

d=16

Assume that the poisson distribution applies and that the mean number of hurricanes in a certain area is 7.2 per year.

SCORPION-xisa [38]

Part A:

The poisson distribution is given by

$P(x;\mu)=e^{-\mu}\cdot \frac{\mu^x}{x!}$

Thus, given that the mean number of hurricanes in a certain area is 7.2 per year.

The probability that, in a year, there will be 6 hurricanes is given by

 $P(6;7.2)=e^{-7.2}\cdot \frac{7.2^6}{6!} \\ \\ =0.000747\times \frac{139314.0695}{720} \\ \\ =0.000747\times193.492 \\ \\ =0.1445$

Part B:

In a 45-year period, the number of years that are expected to have 6 hurricanes is given by 0.1445 x 45 = 6.5 years.

Part C:

The poisson distribution worked here because, the observed value of the number of years that hurricanes occurred in a 45 year period which is 6 is very close to the calculated value which is 6.5

If the car spends 2.5 hours going 35 miles per hour on the trip, how long does it spend going 55 miles per hour?

aleksklad [387]

Simple problem, just use a proportion:
2.5/35 = X/55
Now cross multiply:
137.5 = 35X
X = 3.928

In t hours the train has traveled s miles. Find the formula for v, the speed of the train (in mph) in terms of t and s. Find the

Finger [1]

Answer:

Speed of the train is 60 mph.

Step-by-step explanation:

Given:

In t hours the train has traveled s miles.

t= 3 hrs

s= 180 miles

W need to find the formula for v, the speed of the train (in mph) in terms of t and s.

Also we need to calculate v.

Now by the definition of speed which is stated below.

"Speed is defined as the distance covered by an object per unit time."

"So, mathematically, speed of train v mph is equal to distance traveled by the train s miles divided by time t hours which it takes to cover the distance."

$v=\frac{s}{t}\\$

Now Substituting given values of t and s in above equation we get.

v= $v=\frac{180}{3}=60 \ mph$

Speed of the train is 60 mph
