3+0+4+7+0+4+5+3+6+8/10

40/10

4

Answer:

The mean is 4.

Step-by-step explanation:

When you add 3+0+4+7+0+4+5+3+6+8 you get 40 and because there are 10 numbers you would divide 40 by 10 and get 4.

Mean-the average of all of the numbers in a data set...to find the mean you simply add all of the given numbers together and then divide that sum by the total amount of numbers given, then you will get your mean.

Answer:

x = 6

y = -1

Step-by-step explanation:

-2x + 5y = -17 ------ equation 1

3x- 10y = 28 ------- equation 2

equation 1× 2

-4x + 10y = -34 ------- equation 3

equation 2 + equation 3

-x = -6

x = 6

x = 6 substitute for equation 1

-12 + 5y = -17

5y = -5

y = -1

Answer:

5

Step-by-step explanation:

1/8 divided by 5 equals 1/40

Answer:

[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]

Step-by-step explanation:

Let 'x' be the number to which 1/8 had to be divided to get 1/40

so the equation becomes

[tex]\frac{1}{8}\div \:x=\frac{1}{40}[/tex]

[tex]\frac{\frac{1}{8}}{x}=\frac{1}{40}[/tex]

[tex]\frac{1}{8x}=\frac{1}{40}[/tex]

[tex]\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c[/tex]

[tex]1\cdot \:40=8x\cdot \:1[/tex]

[tex]40=8x[/tex]

switch sides

[tex]8x=40[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}=\frac{40}{8}[/tex]

[tex]x=5[/tex]

x=5 is the number.

Therefore,

1/8 divided by 5 = 1/40

i.e.

[tex]\frac{\frac{1}{8}}{5}=\frac{1}{40}[/tex]

SOLUTION CHECK

[tex]\frac{\frac{1}{8}}{5}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{c}=\frac{a}{b\cdot \:c}[/tex]

[tex]=\frac{1}{8\cdot \:5}[/tex]     ∵ [tex]\frac{\frac{1}{8}}{5}=\frac{1}{8\cdot \:5}[/tex]

[tex]=\frac{1}{40}[/tex]

Step-by-step explanation and answer:

The 6 sides of the die are numbered 1,2,3,4,5,6

There are 3 odd and 3 even numbers

probability of an odd number on 1st roll is:

3/6=1/2

When you want A AND B probabilities, you multiply

the events A and B

The number less than 3 are 1,2, so the probability is:

2/6=1/3

so the probability of both events are going to be:

(1/2) *(1/3)=1/6
