Enter your answer in the box.
mean =
%

Answers

Answer 1

Answer:

Mean = 92.4%

Step-by-step explanation:

You add all of the percentages and divide by how many percentages are there, like, 98 + 97 + 83 + 94 + 90 = 462, since there are 5 percentages, divided it by 5 which gives you 92.4%!

What fraction of the floats were not from a sports team? Write in simplest form.

Answers

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Fraction of the floats that belongs to sports team = [tex]\frac{6}{18}[/tex]

                                                                                  = [tex]\frac{1}{3}[/tex]

Therefore, fraction of floats that were not from a sports team = 1 - fraction of floats that belongs to sports team

= 1 - [tex]\frac{1}{3}[/tex]

= [tex]\frac{2}{3}[/tex]

[tex]\frac{2}{3}[/tex]rd fraction of Parade Float were not from a sports team.

Is 7/12 greater than or less than 4/3

Answers

Answer:

[tex]\frac{7}{12}[/tex] is less than [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Hi there,

When solving this problem, it is highly recommended to have the same denominator. This will make it significantly easier to answer these types of questions.

Since three is a factor of 12, we can multiply the denominator by four to get the same denominator value. This makes [tex]\frac{4}{3}[/tex] equivalent to  [tex]\frac{16}{12}[/tex].

Now that we have the same denominator, it is clear that [tex]\frac{7}{12}[/tex] is less than [tex]\frac{4}{3}[/tex].

Hope this gives you a clearer idea about this concept. Cheers.

The melting temperature of tin is about 231˚ C and the melting temperature for oxygen is about -218˚ C. What is the difference in the melting temperatures for tin and oxygen?

a.144
b.13

Answers

Answer:

[tex]D = 512^\circ[/tex]

Step-by-step explanation:

Given

[tex]Tin=231^\circ[/tex]

[tex]Oxygen=-218^\circ[/tex]

Required

The difference in their melting points

This is calculated as:

[tex]D = |Oxygen - Tin|[/tex]

[tex]D = |-281^\circ - 231^\circ|[/tex]

[tex]D = |-512^\circ|[/tex]

[tex]D = 512^\circ[/tex]

The difference is 512 degrees

Belle deposited money into a savings account. This table gives the value of her account for the first 14 months after the initial deposit. The data can be modeled using an exponential function. \

Years 2 4 6 8 10 12 14
Account value $106 $113 $119 $126 $135 $143 $152

Based on the data, which amount is closest to the value of the account 24 months after the initial deposit?

$180
$200
$240
$280

Answers

Answer:

280

step by step:

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

| years | account value |

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

|    2    |          106           |

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

|    4    |          113           |

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

|    6    |          119            |

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

|    8    |          126           |

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

|   10    |          135           |

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

|   12    |          143           |

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

|   14    |          152           |

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

( haha i had some fun making this table above ^ )

using the table above, we know that

10 + 14

= 24

which means we also have to add up the account value for both of these months

135 + 152

= 285

since the question was asking us which number was the closest then we know that the answer must be 280

if you wanted you could even double check that answer by doing '12 + 12'

12 + 12 = 24

143 + 143 = 186

again since it is the closest to the number 280 then 280 is once again your answer

hope this helps you! :)

Which of the following ordered pairs is a solution to y=2^x

Answers

What are the choices?

Can someone give the answer

Answers

Answer:

(2, -2)

Step-by-step explanation:

Given the equation

x - y = 4 ... 1

6x+y = 10 ...2

Add both expressions

x+6x = 4 + 10

7x = 14

x = 14/7

x = 2

Substitute x = 2 into equation 1;

From 1;

x - y = 4

2 - y = 4

y = 2-4

y = -2

Hence the solution to the system of equation is (2, -2)

Buy any mistakes in the renaming of the fractions below show the correct remaining 9 / 4 = 9 / 12 2 / 3 + 6 / 12

Answers

Step-by-step explanation:

3/4=9/12 CORRECT

2/3=6/12 FALSE

Step-by-step explanation:

What is done to top of the fraction must be done to the bottom as well in order for the renaming to be true.

3*3 = 9

4*3 = 12

Therefore proven to be true

However,

2*3 = 6

but 3*3 = 9

The second fractions is renamed incorrectly and should be either 2/4=6/12 or 2/3=2/9
