Answer:

P( cinder cones ) =  13/37

P ( shield ) =  18/37

P ( stratovolcanoes) =  6/37

Step-by-step explanation:

We need to find the total number of volcanoes

13 +18 + 6 = 37

P( cinder cones ) = number of cinder cones/ total = 13/37

P ( shield ) = number of shield /total = 18/37

P ( stratovolcanoes) = number of Strato /total = 6/37

Step-by-step explanation:

(-4)²×(-4)² = (-4)⁴

(-4)¹⁰/(-4)^n = (-4)^(10‐n)

so,

(-4)⁴ = (-4)^(10 - n)

4 = 10 - n

-6 = -n

n = 6

Answer:

Step-by-step explanation:

Challenge 1

We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.

If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.

Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).

Remember that b cannot be negative.

===========================================

Challenge 2

In the general template provided, enter x = 0.

y = a(b)^x

y = a(b)^0

y = a(1) (1)

y = a

When x = 0 is plugged in, the result is y = a.

The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

Answer:

1. 1,200

2. 6

3. 0.0

4. -0.01187

5. 29.94065

6. 300,000

7. 35,999.9980

8. -239.4065

Step-by-step explanation:

1. 7 Days in a Week

  (3 x 7) - 12 = 24 - 12 = 12

  The question asks for the answer to be in the thousands place, which is (_,xxx.x)  

  Hence, 1,200 is the answer.

2. difference means subtract

   (5-2) + 3 = 3 + 3 = 6

   The answer is 6 because it says the ones place, which is (x_.x)

3. The answer is 0.0

You do not even have to do the math because multiplying by 0 will          always equal 0, but since it asks for the answer in the tenths place (x._),  then the answer is 0.0

4. To start, there are 28 days in February, on a non-leap year.

   There are 2 days in one weekend.

    28-2 = 26

    Next, the problem says divide by 2

    26/2 = 13

    Then, the problem says subtract the number in the thousands place, being 1,200, from the 13.

    13 - 1,200 = -1187

    FInally, the question asks us to put the answer in the hundredths place, which is (x.x_ ).

    The final answer is  -0.01187

5.  Tenth Place = 0.0

      Hundredths Place = -0.01187

      Ones Place = 6

       The problem is asking for the tenth, ones, and hundredth place to all be added up.

      0.0 + ( - 0.01187) + 6 = 5.98813      

      Then, the problem asks us to divided the answer, being 5.98813, by 2

      5.98813/2 = 2.994065

      Finally, the problem asks for us to put the answer in the the tens place,  which is _x.x.

      Therefore, the answer is 29.94065

6. To start, there are 24 hours in one day

   (24 x 2) = 48

    Then the problem asks for us to divide 48 by 16

    48/16 = 3

    Finally, the problem asks for us to put the answer in the hundred thousands place, which is (_xx,xxx.x)

    Therefore, the answer is 300,000.

7. Hundred Thousands Place = 300,000

   Thousands Place = 1,200

   The problem is asking us to multiply the hundred thousands place, being 300,000 by the thousands place, being 1,200.

   300,000 x 1,200 = 360,000,000

    Then, the problem is asking to subtract 12 from that answer, being 360,000,000.

    360,000,000 - 20 = 359,999,980

    Finally, the problem is asking to put the answer in the ten thousands place, which is (x_x.xx)

    The answer would be 35,999.9980.

8. Tens Place = 29.94065

   Ones Place = 6

   The problem is asking to subtract the number in the tens place, being 29.94065, from the number in the ones place, being 6.

   6 - 29.94065 = -23.94065

   Finally, the problem asks for the answer to be written in the hundred place, which is (x_xx.xx).

   Therefore, the answer is -239.4065

Answer:

Step-by-step explanation:

(1) Number of days in a week = 7

(3*7) - 12

= 21-12

= 9

9 in thousands place --> 9*1000 = 9000

(2) Difference of 5 and 2 = 5-2 = 3

Now, add 3

3 + 3 = 6

6 in ones place --> 6*1 = 6

(3) Any number multiplied by 0 = 0

So, 0 in tens place --> 00

(4) Number of days in a weekend = 2

Number of days in Feb (non-leap) = 28

Difference = 28-2 =26

∴ 26÷2 = 13

(5) \(\frac{\frac{1}{10}+ \frac{1}{100}+ 1 }{2}\)

Answer:

50mph

Step-by-step explanation:

Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.

A = 50+10

b = 50-10

A = 60

B = 40

A2 = 120

B3 = 120

120 = 120

You want the length of a rectangle that has an area of 155 m² and a width of 15.5 m.

The area formula is ...

  A = LW

Filling in the given values, we have ...

  155 m² = L(15.5 m)

Dividing by 15.5 m gives ...

Answer: x = 0.22 cents

Step-by-step explanation: This is my first time trying to help someone so if I get something wrong I AM SO SORRY!!!!

First, find the unit rate of both companies.

To find company A's unit rate find what is the numerator and denominator. This is 65/13. We want a unit rate where 1 is in the denominator, so we divide the top and bottom by 13:

65 cents / 13

--------------------

13 dollars / 13

Divide both by 13 and you get 5 cents per dollar.

Now find company B's unit rate. Find the numerator and denominator, 11/40.50. Now this time we want 1 where the denominator is again. So we divide the top and bottom by 40.5.

11 cents ÷ 40.5

----------------------------------

40.5 dollars ÷ 40.5

Divide by 40.5 and you get 0.271605 cents per dollar. Round to the hundreths and get 0.27 cents per dollar

Now time to find how much company A charges more than company B. subtract 0.27 by 0.05 and you have your answer! x = 0.22 cents

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Step-by-step explanation:
