Probability of someone either owning a dog or being male.<br>

andrey2020 [161]

Answer:

c. 60.278%

Step-by-step explanation:

There is a 27.778% probability that someone owns a dog.

There is a 45% probability that someone is a male.

However, these two are not mutually exclusive. 12.5% both own a dog and are male. If we simply add 27.778% and 45%, we'll be double counting the overlap. To avoid this, we subtract 12.5%.

27.778% + 45% − 12.5% = 60.278%

Solve 3x²-x-2=0. Please show all work.

lorasvet [3.4K]

3x²-x-2=0

Δ=1+24=25 (Δ=b²-4ac)

x₁,₂= $\frac{1(+/-)\sqrt{25} }{6}$

x₁,₂= $\frac{1(+/-)5}{6}$

x1= $\frac{1+5}{6}$ =6/6=1

x2= $\frac{1-5}{6}$ = $\frac{-2}{3}$

x1=1

x2= $\frac{-2}{3}$

A cylinder has a circular base with a diameter of 12 ft the height of the cylinder is 4 feet what is the volume of the cylinder

Murrr4er [49]

Answer:

$452\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$r=12/2=6\ ft$ ----> the radius is half the diameter

$h=4\ ft$

substitute the values

$V=(3.14)(6^{2})(4)=452\ ft^{3}$

Rocky lends $3000 to Ken at 10% per annum and the Ken lends the same sum to like at 12% per annum. Find kens gain over a period

zalisa [80]

Let t = time

Between Rocky and Ken:

3000 + 3000(.10)(t)

Between Ken and Mike:

3000 + 3000(.12)(t)

Kens gain = The difference
