If a fair die is rolled 6 times, what is the probability, rounded to the nearest

Mathematics
1 answer:
zloy xaker [14]3 years ago
3 0

Answer:

Step-by-step explanation:

The probability of getting something other than a 6 is

5/6

The probability of getting 5 sixes is

1/6 * 1/6 * 1/6 * 1/6 * 1/6 * 5/6

5 / 6^6 =0.000107167

And if you should draw all sixes The Probability is

(1/6)^6 = .000021433

The probability of getting at least 5 sixes is the sum of these two numbers.

0.0001286

Rounded to the nearest 1/1000 is 0. In other words, not very likely which you probably knew without the math.

A rectangular school banner has a length of 60 inches and a width of 48 inches. A sign is made that is similar to the school ban
natulia [17]

Answer:

The ratio of the length of the banner to the length of the sign = 54/17

So....since they are similiar figures, the widths will have the same ratio

And the ratio of the area of the banner to the area of the sign will be the square of this ratio  

Step-by-step explanation:

[54/17]^2  = 2916/289

If EF bisects angle CEB, angle CEF=7x + 21 and angle FEB = 10x - 3, find the measure of DEB.
morpeh [17]

Answer: DEb = 26°

Step-by-step explanation:

<u>Given information</u>

CEF = 7x + 21

FEB = 10x - 3

<u>Given expression deducted from the definition of the bisector</u>

FEB = CEF

<u>Substitute values into the expression</u>

10x - 3 = 7x + 21

<u>Subtract 7x on both sides</u>

10x - 3 - 7x = 7x + 21 - 7x

3x - 3 = 21

<u>Add 3 on both sides</u>

3x - 3 + 3 = 21 + 3

3x = 24

<u>Divide 3 on both sides</u>

3x / 3 = 24 / 3

x = 8

<u>Find the sum of the angle of CEF and FEB</u>

 7x + 21 + 10x - 3

=7 (8) + 21 + 10 (8) - 3

=56 + 21 + 80 - 3

=77 + 80 - 3

=157 - 3

=154

<u>Subtract 154 from the straight angle</u>

DEB = 180 - 154

\boxed{DEB = 26}

Hope this helps!! :)

PLEASE HELP!!!!!! what is the purpose of arithmetic and geometric sequences?
goblinko [34]

Answer:

An arithmetic sequence has a constant difference between each term. ... A geometric sequence has a constant ratio (multiplier) between each term. An example is: 2,4,8,16,32,… So to find the next term in the sequence we would multiply the previous term by 2.

Delicious77 [7]

Answer:

6 crayons more

Step-by-step explanation:

At Dante's party, each child gets 192/16 = 12 crayons each

At Maria's party, each child gets 234/13 = 18 crayons each.

Therefore, each child at Maria's party gets 18-12 = 6 crayons more each than at Dante's party.
