Answer:

6q or 6 * q

John and Ellen bought a big pizza. Ellen are 2/4 of the pizza and John ate 1/3 of pizza. How much did they eat all together? How much was left over? ( hint 12 is the lowest common denominator)

(I put 1/4 but it said it was wrong:/) pls help h

Answers

Answer:

Pizza eaten together: 5/6,

Pizza left over: 1/6

Step-by-step explanation:

~ If Ellen ate 2/4th of the pizza and John ate 1/3 of the pizza, provided that the pizza counts as a whole ( 1 )... ~

1. Let us simplify 2/4th to be ⇒ 1/2, through simple algebra

2. To see how much they ate together we would neglect that the pizza counts as a whole but simply add 1/2 by 1/3rd.

3. Through simple algebra: 1/2 + 1/3 = 3/6 + 2/6 = Pizza eaten together: 5/6

4. Now to find out how much pizza was left over, we would need the fact that a pizza ⇒ 1 whole. It would be that 1 - 1/2 - 1/3 ⇒ Pizza left over, through the Partition Postulate. In fact, the pizza left over would simply be 1 whole - the pizza eaten together ( 5/6 ).

5. Through algebra: 1 - 1/2 - 1/3 = 1 - 5/6 = Pizza left over: 1/6

Answer:

How much did they eat all together? 5/6

How much was left over? 1/6

[tex] \\ [/tex]

Step-by-step explanation:

How much did they eat all together?

[tex] \frac{2}{4} + \frac{1}{3} \\ = \frac{6}{12} + \frac{4}{12} \\ = \frac{10}{12} \\ = \frac{5}{6} [/tex]

[tex] \\ [/tex]

32%
689

99.75

Answers

Answer:

About 68% (is that an answer choice?)

Step-by-step explanation:

In a normal distribution (a bell curve), about 68 percent of the data is in the range between one standard deviation below the mean to one standard deviation above.  If your mean is 27, and the standard deviation is 3, then one deviation below to one above would be 27 - 3  to 27 + 3, or 24 - 30.

Step-by-step explanation:

The angle given is in the 3rd quadrant, so the tangent is negative. The reference angle is ...

  180° -162° = 18°

Tangent is an odd function, so ...

  tan(-x) = -tan(x)

This means we can write the required ratio two ways:

What is the level of measurement for each of the following variables? a. Distance students travel to class b. A classification of students by the state of birth c. A classification of students by ethnicity d. A classification of workers by industry e. Selling price of the Statistics textbook f. Student IQ ratings

Answers

Answer/Explanation:

There are basically 4 main levels of measurement or scales of measurement. They are:

1. Nominal scale: this deals with variables that are categorised, and numbers o i.e.r alphabets assigned are just for the sake of naming, and as such has no numeric value.

2. Ordinal scale: this scale is only used to show order or ranking if variables.

3. Interval scale: in this type of scale, numbers that are ordered have meaningful divisions.

4. Ratio scale: this can be like to interval scale, in that, the ordered numbers have meanings. However, unlike the interval scale, when zero is used, meaningful deductions can be made as zero is meaningful.

Therefore, level of measurement for the variables given in the question are as follows:

a. Distance students travel to class: ratio scale. I.e. zero in this scale is meaningful and would mean no distance was travelled

b. A classification of students by the state of birth: nominal scale, i.e. this only serves the purpose of categorization. The scale here has no numeric value,

c. A classification of students by ethnicity: nominal scale

d. A classification of workers by industry: nominal scale

e. Selling price of the Statistics textbook: ratio scale

f. Student IQ ratings: interval scale, i.e., zero in this scale is not meaningful.

Ricky has a bowl with 80 jelly beans in it there are 16 red, 24 green 12 yellow, 20 orange, and 8 black jelly beans ricky takes one jellybean from the bowl without looking what is the possibility that it is a yellow jellybean

Answers

Answer:

Probability = number of yellow jellybeans / total number of jellybeans

=  24 / 80

=  3/10.

Step-by-step explanation:

Answer:

15%

Step-by-step explanation:

There are 80 total jelly beans, as stated in the question. Therefore, there are 80 "Total Events".

There are 12 yellow jellybeans in the bowl. Therefore, there are 12 preferred events, since the question asks the probability of pulling one yellow jellybean randomly.

[tex]\frac{\text{Preferred Events}}{\text {Total Events}} =\frac{12}{80}[/tex]

I do not know what form the question prefers, so I did the probability in all forms.

Probability as a decimal:

Divide 12 by 80.

[tex]12/80 = 0.15[/tex]

There is a 0.15 chance that Ricky would pull out a yellow bean.

Probability as a Percent:

Divide 12 by 80.

[tex]12/80=0.15[/tex]

Convert into a percent. Multiply 0.15 by 100.

[tex]0.15*100=15[/tex]

There is a 15% chance that Ricky would pull out a yellow bean.

Probability as a Fraction:

Simplify 12/80.

[tex]\frac{12/2}{80/2} =\frac{6/2}{40/2} =\frac{3}{20}[/tex]

There is a [tex]\frac{3}{20}[/tex] chance that Ricky would pull out a yellow bean.

Calculate an estimate of the mean travelling time.​

Answers

Answer:

24.8 mins

Step-by-step explanation:

Time > timemark > frequency

0 – 10 > 10/2 = 5 > 5

10 – 20 > (10+20)/2 = 15 > 15

20 – 30 > (20+30)/2 = 25 > 13

30 – 40 > (30+40)/2 = 35 > 10

40 – 50 > (40+50)/2 = 45 > 7

The mean time for the 50 people is given by:

Mean = summation (mid time x frequency) / total frequency

Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50

Mean = [25 + 225 + 325 + 350 + 315] / 50

Mean = 1240 / 50

Mean = 24.8 mins

The mean traveling time of the given data will be 24.8 minutes.

What is Mean?

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.

   Time >     timemark     >    frequency

 0 – 10 >      10/2 = 5       >          5

10 – 20 > (10+20)/2 = 15  >         15

20 – 30 > (20+30)/2 = 25 >       13

30 – 40 > (30+40)/2 = 35 >        10

40 – 50 > (40+50)/2 = 45 >         7

The mean time for the 50 people is given by:

Mean = summation (mid time x frequency) / total frequency

Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50

Mean = [25 + 225 + 325 + 350 + 315] / 50

Mean = 1240 / 50

Mean = 24.8 mins

The mean traveling time of the given data will be 24.8 minutes.

A 13​-pound mixture of coffee that contains both decaffeinated and regular coffee costs ​$34. The decaffeinated coffee costs ​$2 per​ pound, and the regular coffee costs ​$3 per pound. ​(a) Let x be the weight of the decaffeinated coffee and y be the weight of the regular coffee. Write a system of equations whose solution gives the amount of each type of coffee in the mixture. ​(b) Use the method of substitution to solve the system of equations.

Answers

Answer:

Weight of decaf coffee = 5 pounds.

Weight of regular coffee = 8 pounds.

Step-by-step explanation:

(a) Let x be the weight of decaf coffee and y the weight of regular coffee. Then:

x + y = 13

2x + 3y = 34

(b) From the first equation x = 13 - y, so substituting for x in second equation:

2(13 - y) + 3y = 34

26 - 2y + 3y = 34

y = 34 - 26 = 8.

Substituting for y in the first equation:

x + 8 = 13

x = 5.

Answer:

x = -2 or x = 1/3 thus: B & C

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + 7 x - 2 = 2 x - x^2

Subtract 2 x - x^2 from both sides:

3 x^2 + 5 x - 2 = 0

The left hand side factors into a product with two terms:

(x + 2) (3 x - 1) = 0

Split into two equations:

x + 2 = 0 or 3 x - 1 = 0

Subtract 2 from both sides:

x = -2 or 3 x - 1 = 0

Add 1 to both sides:

x = -2 or 3 x = 1

Divide both sides by 3:

Answer: x = -2 or x = 1/3

b) (t + 4)( t + 2)

d) (t + 4)(t – 2)

Answers

Answer:

Step-by-step explanation:

Try completing the square:  t^2 - 2t + 1 - 1 + 4 becomes (t - 1)^2 + 3.  If we set this equal to zero we get (t - 1)^2 = -3.  Normally we'd take the square root of both sides, but because that -3 is negative, this is not possible, and the square root of positive 3 is not integer.  Thus, the correct response here is "prime."
