Answer:

The sample space is S={HHH, TTT, HTT, HHT, TTH, THH, THT, HTH}

Step-by-step explanation:

Given that a coin is flipped three times.

H represents heads, and T represents tails.

we have to find the sample space.

The sample space contains $2^n=2^3=8$ elements.

As three times the coin is flipped.

∴ The possible outcomes i.e the sample space is

S={HHH, TTT, HTT, HHT, TTH, THH, THT, HTH}

The first choice is correct option.

The population of a town is decreasing at a rate of 3.2% per year. In 2015, there were 14,250 people. What is the first year tha

notsponge [240]

The answer is D
you would set up an equation like this
14,250 x .032
this will give you how much the population is decreasing per year. Which is 456 people per year.
You then take 2015 and find the difference between that number and 2025 and do it with all of the other years too.
For example 2025-2015 is 10 years
You then take 10 x 456 to tell you how much the of population you lost in those 10 years. You will then take that number which is 4,560 and do 14,250-4,560 to get 9,650.

Find the radius, and the approximate circumference and area of the circle below. (Use 3 for \pi)

Marina CMI [18]

Answer:

Circ=37.704, Area= 112.112

Step-by-step explanation:

Circumference= pi *Diameter

Taking pi=3.142, Diameter=12

Circ=3.142*12=37.704

Area= pi * r^2

Area= 3.142*6*6=112.112

Solve for r in terms of s, t, and u. t=u-s+r

Verdich [7]

Answer:

r = t - u - s

Step-by-step explanation:

To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.

t = u - s + r

t - u = s + r

t - u - s = r

Find two positive real numbers whose product is a maximum. (enter your answers as a comma-separated list.) the sum of the first

Vladimir [108]

the sum of the first and three times the second is 54.

x + 3y = 54

3y = 54 - x

y= 54 /3 - x / 3 = 18 -x /3

xy = x (18 -x /3) = 18x - x^2 / 3 = - 1/3 x ^ 2 + 18 x


since a<0, it is concave downward, and the vertex is the maximum value. That vertex occurs at x= - b /2a = (-18) / (-2/3) = 12


The first number is x=12.
The second is y = 18 -x /3 = 18- 12/ 3 = 18 - 4 = 14
