The probability that the dog that's selected will weigh less than 30 pounds will be 55%.

<h3>How to calculate probability?</h3>

From the information given, it was stated that 45% of the dogs weigh more than 30 pounds. Therefore, the probability that the dog that's selected will weigh less than 30 pounds will be:

= 1 - 45%

= 55%

The probability that it weighs more than 30 pound given that it has long fur will be 27%.

The events are independent since the occurence of one doesn't affect the other one.

A fan oscillates 250* and can be felt from a distance of 4 feet away . To the nearest tenth what area of the room can feel the w

Vanyuwa [196]

Answer:

$A=256.67ft^2$

Step-by-step explanation:

From the question we are told that:

Fan oscillates $\theta=250$

Distance $d=>Raduis\ r=4 feet$

Since

$250\textdegree =180\textdegree +70\textdegree$

Generally the equation for the area A is mathematically given by

$Area=Area\ of\ semi\ circle\ + area\ of\ 70\textdegree sector$

$A=A_{sm}+A_{70\textdegree}$

Where

$A_{sm}=\frac{1}{2} \pi r^2$

$A_{sm}=\frac{1}{2} 3.14 4^2$

$A_{sm}=25.12ft^2$

$A_{70\textdegree}=\frac{1}{2}r^2 \frac{70\textdegree}{360\textdegree}$

$A_{70\textdegree}=\frac{1}{2}*4^2* \frac{70\textdegree}{360\textdegree}$

$A_{70\textdegree}=1.55ft^2$

Therefore the area A is given as

$A=A_{sm}+A_{70\textdegree}$

$A=25.12ft^2+1.55ft^2$

$A=256.67ft^2$

A town has a population of 5000 and grows at 4% every year. What will be the population after 7 years, to the nearest whole numb

dimulka [17.4K]

Answer: The population would be 6580 after 7 years.

Step-by-step explanation:

The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

y = b(1 + r)^ t

Where

y represents the population after t years.

t represents the number of years.

b represents the initial population.

r represents rate of growth.

From the information given,

b = 5000

r = 4% = 4/100 = 0.04

t = 7 years

Therefore

y = 5000(1 + 0.04)^7

y = 5000(1.04)^7

y = 6580
