Answer:

3 1/2

Step-by-step explanation:

4 1 3

_ - _ = _

6 6 6

Then we simplify. 3 3 1

_ ÷ = _

6 3 2

Then just add your 3 and there 3 1/2 is your asnwer

The difference between 3 4/6 and 1/6 will be 3 1/2.

Given numbers are:

(1)[tex]3\frac{4}{6}[/tex] [tex]=\frac{22}{6}[/tex]

(2)[tex]\frac{1}{6}[/tex]

A fraction is a part of a whole.

The Difference between [tex]3\frac{4}{6}[/tex] and [tex]\frac{1}{6}[/tex] will be = [tex](\frac{22}{6} )-(\frac{1}{6} )[/tex]

[tex]=\frac{22}{6} -\frac{1}{6}[/tex]

[tex]=\frac{21}{6}[/tex]

[tex]=\frac{7}{2}[/tex]

[tex]=3\frac{1}{2}[/tex]

Hence, the difference between 3 4/6 and 1/6 will be 3 1/2.

Answer:

J' = (-15, -10)

K' = (5, 20)

L' = (20, 10)

Step-by-step explanation:

Given the coordinates J(–3, –2), K(1, 4), and L(4, 2)

D5(ΔJKL) means we need to dilate the coordinates by a constant of 5

To do that, we will multiply the coordinates by a value of 5

D5(ΔJKL)

J' =  (5(–3), 5(–2)),

J' = (-15, -10)

K' = (5(1), 5(4))

K' = (5, 20)

L' = (5(4), 5(2))

L' = (20, 10)

Answer:

x  ≈ ± 3.87

Step-by-step explanation:

Given

x² - 3 = 12 ( add 3 to both sides )

x² = 15 ( take the square root of both sides )

x = ± [tex]\sqrt{15}[/tex]

Then x ≈ 3.87 or x ≈ - 3.87 ( to 2 dec. places )

Answer: 83

Step-by-step explanation: 17% of 500 is 85. If 17% is empty, that means that you'd take away that 15%. 500 - 85 = 415. If each page holds 5 cards, we need to split those cards up between the pages. 415/5 = 83, so 83 pages will be used.

Answer:

x = 6

y = 6[tex]\sqrt{2}[/tex]

z = 12

Step-by-step explanation:

the ratio of sides in a 30-60-90° triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2

therefore, 'x' must have a measure of 6

which means the hypotenuse must have a measure of 12

other triangle is a 45-45-90° triangle whose sides are in a ratio of 1 to [tex]\sqrt{2}[/tex]

this means that 'y' must be 12/[tex]\sqrt{2}[/tex] which is 6[tex]\sqrt{2}[/tex]

'z' must be 6[tex]\sqrt{2}[/tex] · [tex]\sqrt{2}[/tex] = 12

Answer:

We can convert a mixed number (or mixed fraction) to a decimal. Strategies to convert mixed fractions to decimals: Change the mixed fraction to an improper fraction and then divide. Convert the fractional part only and then add it to the whole number.

Answer:

Yes

Step-by-step explanation:

Any mixed number that you have, is really the whole number and a set amount of fractions behind it.

If you have 3  [tex]\frac{6}{9}[/tex], then you can change that to 3.6666.... If you have 1  [tex]\frac{1}{2}[/tex], then you can change that to 1.5.

Answer:

x < -2 (No, he shouldn't have reversed the inequality symbol).

Step-by-step explanation:

Given the algebraic expression;

19 - 2(1 - x) < 13

Opening up the bracket, we have;

19 + (-2*1) + (-2*-x) < 13

19 + (-2) + (2x) < 13

19 - 2 + 2x < 13

17 + 2x < 13

Rearranging the equation, we have;

2x < 13 - 17

2x < -4

Dividing both sides by 2, we have;

x < -2

Hence, your friend shouldn't have reversed the inequality symbol (sign).

Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.

For example, if we had re-arranged the equation as;

17 - 13 < -2x

4 < -2x

Dividing both sides by -2, we have;

4 > x

Answer:

1140 households

Step-by-step explanation:

The results of a computer survey of 80 households in Westville are shown in the table.

So from the table we can see that 6 households have 3 numbers of computers.

So the probability is [tex]$\frac{6}{80}$[/tex]

Therefore, the probability of number of houses from a total of 15,200 houses to have exactly three computers is = [tex]$\frac{6}{80} \times 15200$[/tex]

                                                          = 1140 houses

Answer:

x = 55, because if you look the whole entire bar is 180° in total but you dont have to worry about that because that's not what the question is wanting you to look at, If you look really close there is a half and half on both sides so that means there is a 90° angle so you would have to take 90-35 and that is what gives you your missing angle which is 55.

Answer:

Mila had $48 initially

Step-by-step explanation:

Let the amount of money they had be x

Mila spent $42; what is left would be x-42

Samuel spent $36: what is left would be x-36

So, what Mila had left is half of what Samuel has; that would be;

x-42 = 1/2(x-36)

2(x-42) = x -36

2x-84 = x -36

2x - x = 84 -36

x = $48

The statements which are correct are B, C and E.

Relative frequency is defined as the ratio of the frequency by the total count of the data values.

We have to find the relative frequency in each option.

A) Frequency of "like snowmobiles" and "like skateboards" = 80

Total count = 160

Relative frequency of "like snowmobiles" and "like skateboards" = 80 / 160 = 0.5 = 50%

B)  Frequency of "like snowmobiles" and "do not like skateboards" = 25

Total count = 160

Relative frequency of "like snowmobiles" and "do not like skateboards" = 25 / 160 = 0.15625 = 15.6%

C) Frequency of "like snowmobiles" and "like skateboards" = 80

Total row frequency = 105

The row conditional relative frequencies of "like snowmobiles" and "like skateboards" = 80 / 105 = 0.7619 = 76.19% ≈ 76.2%

D) Frequency of "do not like snowmobiles" and "like skateboards" = 45

Total row frequency = 55

The row conditional relative frequencies of "do not like snowmobiles" and "like skateboards" = 45 / 55 = 0.81818 = 81.82%

E) Frequency of "do not like snowmobiles" and "do not like skateboards" = 10

Total column frequency = 35

The column conditional relative frequencies of "do not like skateboards" and "do not like snowmobiles" = 10 / 35 = 0.2857 = 28.57% ≈ 28.6%

Hence the correct statements are B, C and E.

Answer: 17/19

Step-by-step explanation:

Number of red rocks = 6

Number of orange rock = 1

Number of blue rocks = 4

Number of white rock = 1

Number of yellow rocks = 7

Total number of rocks = 19

Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.

Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18

Probability of not getting an orange on both occasion will be:

= 18/19 × 17/18

= 17/19
