Answer:

Step-by-step explanation:

When the growth (or decay) amount is a fraction or percentage of the current amount, an exponential model is indicated. Here, it will be of the form ...

  value = (initial value) × (1 + (growth rate))^t

where t is the time period corresponding to the growth rate.

We are given that the initial value is $342,000 and the growth rate is 6% in a year. So, the model can be ...

  value = 342,000×1.06^t . . . . . where t is years after 2017

__

In 2025, we are 8 years after 2017, so the value is predicted to be ...

  value = $342,000×1.06^8 ≈ $545,096 . . . in 2025

__

In 2032, we are 15 years after 2017, so the value is predicted to be ...

  value = $342,000×1.06^15 ≈ $819,623 . . . in 2032

Answer:

0.647 = 64.7% probability that none of them has lost electricity in his/her household

Step-by-step explanation:

For each household, there are only two possible outcomes. Either they lost electricity, or they did not. The probability of a household losing electricity is independent of any other household. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

A rainstorm in Portland, Oregon, has wiped out the electricity in about 7% of the households in the city.

This means that [tex]p = 0.07[/tex]

6 members

This means that [tex]n = 6[/tex]

What is the probability that none of them has lost electricity in his/her household?

This is P(X = 0). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{6,0}.(0.07)^{0}.(0.93)^{6} = 0.647[/tex]

0.647 = 64.7% probability that none of them has lost electricity in his/her household

Answer:

43/120 ≈ 0.3583

Step-by-step explanation:

Adding up the folks who use two facilities counts the folks who use all three 3 times. So, the number who use two or more facilities is ...

 21 +16 +24 -2(9) = 43 . . . . people who use 2 or more facilities

The probability that a person chosen randomly from the 120 at the sports center uses at least 2 facilities is ...

43/120 ≈ 0.3583

Answer:

x = 30°

Step-by-step explanation:

the small triangle is equilateral

That means that side with angle x that shares the same side with the other triangle is also 40

so its isosceles

in the equilateral, all angles measure 60

so 180 -60 = 120

180 - 120 = 60

60/2 = 30

Answer:

2.1134 liters

Step-by-step explanation:

There are 4 quarts in a gallon and each quart is 1.0567 liters. 2 quarts are 1/2 a gallon. 1.0567*2=2.1134

9514 1404 393

Answer:

  2.  1.8927 L

  3.  603.22 cm²

Step-by-step explanation:

To convert units, multiply by a ratio whose value is 1. That is, the numerator and denominator are equal amounts, but have units that cancel ones you don't want and give you units you do want.

2.

  [tex]\displaystyle \frac{1}{2}\text{ gal}\times\frac{4\text{ qt}}{1\text{ gal}}\times\frac{1\text{ L}}{1.0567\text{ qt}}=\frac{4}{2\times1.0567}\text{ L}\approx\boxed{1.8927\text{ L}}[/tex]

__

3.

  [tex]A=LW=(8.5\text{ in})(11\text{ in})\times\left(\dfrac{2.54\text{ cm}}{1\text{ in}}\right)^2=\boxed{603.2246\text{ cm}^2}[/tex]

_____

Additional comment

It can be helpful to remember that a liter is larger than a quart. So 2 quarts will be less than 2 liters. (You may recall reading on the half-gallon container that it holds 1.89 L.)

The surface area of the square pyramid is, A. 80 in².

A three-dimensional figure is a pyramid. Its base is a flat polygon. The remaining faces are all triangles and are referred to as lateral faces.

The number of sides on its base is equal to the number of lateral faces. The line segments that two faces intersect to form its edges. The intersection of three or more edges forms a vertex.

The given figure is a pyramid having a square base.

The pyramid also has four triangular faces, each having a base of 5 in and a height of 8 in.

Therefore, the surface area of the pyramid is,

= 4[(1/2)×5×8] square inches.

= 80 in².

The answer is just one bro

Y= 3

Just did my test and got it correct

The correct equation describes the asymptote of the exponential function represented by this graph is,

⇒ y = 3

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since, The exponential function of the type,

⇒ y = a (bˣ) + c

Which has the horizontal asymptote at y = c.

Hence, From the given graph, we can see that as x tends to positive infinity, Thus, the curve tends to;

⇒ y = 3

Thus, The correct equation describes the asymptote of the exponential function represented by this graph is,

⇒ y = 3

Step-by-step explanation:

Boys: Girls

2     :   5

Question: How many boys are there if there are 90 girls?

The question is basically asking an equivalent ratio...

Let x be the number of boys.

[tex]\frac{2}{5}[/tex] = [tex]\frac{x}{90}[/tex]

90 ÷ 5 = 18

So, if you multiply 18 by the number of the previous girls (5) you get 90

Therefore, you multiply 18 with the previous no. of boys (2) and that would be you equivalent answer!

option A is the correct one.

Answer:

A=[tex]\pi[/tex]100

A=314.159

2 slices = 1/4

1/4x314.159=78.5399 centimters squared.

Paragraph:

    Firstly, the question has an error.  It says that the personal pan pizza is 80 cm³.  It should be cm², since it’s area and not volume. You have to figure out the area of the 20 inch pizza using A=[tex]\pi[/tex]r².  Since the diameter is 20, the radius is 10, and the area ends up being 314.159.  Two slices is 1/4 of the diameter, or 0.25.  Multiply 314.159x0.25, and. You get 78.5399 square centimeters.  This is just under the 80 that he is allowing himself, so he has made the correct choice.
