Answer:

<h2>ANSWER→ </h2>
  • 16 miles
  • 12 minutes is 1 /5 of a hour
  • 80 ÷ 5 is 16
  • or 80x 1.466 =117.28 ft per second
  • 12 minutes x 60 seconds is 720
  • 117.28× 720= 84,441.6
  • 84441.6÷ 5280= 15.992 miles.

In 1990 four towns had the same population. Since then, the population of town 1 grew by a factor of 1.02, the population of tow
Alborosie

Answer: Town 1

Step-by-step explanation:

Town 1's population is growing at a factor of 1.02 which means that it is increasing by 2% a year.

Town 2 is growing at a factor of 0.999 which means that it is decreasing at a rate of:

= 1 - 0.999

= 0.1%

Town 3's population is increasing by 150 a year and town 4 is 200 people a year.

Town 1 will eclipse them all eventually because it is <u>growing proportionally at 2%</u>.

Towns 3 and 4 will eventually see 150 and 200 people fall below 2% of their town's population which means they will be growing at a slower rate than Town 1.

A wire 390 in. long is cut into two pieces. One piece is formed into a square and the other into a circle. If the two figures ha
jeka57 [31]

Answer:

Step-by-step explanation:

Let x is the length of the square side.

We know: the two figures have the same area

<=> x^{2} = πr^{2} (r being radius)

<=> x = \sqrt{II} r

perimeter square = 4x = 4*r*\sqrt{II}

perimeter circle = 2*r*π

<=> 390 = 4*r*\sqrt{II}  + 2*r*π

<=> r = 29.16

=> perimeter square =  4*29.16*π

=> perimeter circle = 58.32π

A study was done to compare people's religion with how many days that they have said they have been calm in the past three days.
nadezda [96]

Answer:

The probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.

Step-by-step explanation:

Represent the provided data as follows:

Compute the probability of the number of Protestants that were calm for 2 out of 3 days as follows:

P (Calm\ for\ 2\ days\ |\ Protestants) = \frac{n (Protestants\ who\ were\ calm\ for\ 2\ days}{n (Protestants}

The number of Protestants surveyed is, <em>n</em> (Protestants) = 99.

The number of Protestants who were calm for 2 days,

<em>n</em> (Protestants who were calm for 2 days) = 6

The required probability is:

P (Calm\ for\ 2\ days\ |\ Protestants) = \frac{n (Protestants\ who\ were\ calm\ for\ 2\ days}{n (Protestants}\\=\frac{6}{99}\\ =0.060606\\\approx0.061

Thus, the probability of the number of Protestants that were calm for 2 out of 3 days is 0.061.
