What are the two types of reinforcers?

The class with the greatest frequency is the class "15.2 - 19" with a frequency of 7. The class with the least frequency is the class "0 - 3.8" with a frequency of 2.

To construct a frequency distribution with 5 classes for the given data representing time spent reading a political blog in a day, we need to determine the class intervals and calculate the frequency, midpoint, relative frequency, and cumulative frequency.

First, we find the range of the data:

Range = Maximum value - Minimum value

Range = 19 - 0

Range = 19

To determine the class width, we divide the range by the desired number of classes:

Class width = Range / Number of classes

Class width = 19 / 5

Class width ≈ 3.8

Now, we can construct the frequency distribution table:

Class          Frequency   Midpoint   R. Frequency   C. Frequency

0 - 3.8           2              1.9                2/20 = 0.1           2

3.8 - 7.6        4              5.7                4/20 = 0.2           6

7.6 - 11.4      4              9.5                4/20 = 0.2           10

11.4 - 15.2    3              13.3              3/20 = 0.15         13

15.2 - 19       7              17.1              7/20 = 0.35         20

By organizing the data into classes and analyzing the frequencies, we can gain insights into the distribution of reading time and identify the most and least common time intervals spent on reading the political blog.

Where there are 221 identical plastic chips number one through 221 in a box the probability Ricch on the box and randomly drawn chip number 170 is 0.00452

Assuming that each chip has an equal probability of being drawn and that Ricch is not a specific chip number, the probability of Ricch drawing chip number 170 is 1/221 or approximately 0.00452 (0.452%).

We can state the above because because there is only one chip numbered 170 out of a total of 221 chips.

2. Meeting facilities without lodging: are convention centers that do not includeaccommodation; usually located adjacent to or near a hotel(s).

3. Other: any convention and meeting facilities designed to hold large numbers of people.Can exist alone (e.g., stadiums, arenas, parks, etc.) or within other structures (e.g.,university lecture halls, museums, theaters). Usually do not include accommodation.

Answer:

there are 1/4 cups of Super Grain Cereal in the mixture

Explanation:

Super Grain cereal provides 240 calories per cup. Thus, for s cups of Super Grain cereal, there will be 240s calories

Crunchy Grain cereal provides 210 calories per 3/4 cups. Thus, 210 ÷ 3/4 per cup.

210 ÷ 3/4 = 280 calories, For c cups of Crunchy Grain cereal, there will be 280c calories

Jennifer mixes c cups of Crunchy Grain cereal, having 280 calories and s cups of Super Grain cereal, having 240 calories to get a final 1 cup mixture containing 270 calories, which can be expressed mathematically as:

280c + 240s = 270 ------- eqn(1)

Since, s cups of Super Grain cereal and c cups of Crunchy Grain cereal equals 1 cup, of the final mixture

c + s = 1 ------- eqn(2)

from eqn(2),

c = 1 - s

substitute c = 1 - s into eqn(1)

280(1 - s) + 240s = 270

280 - 280s + 240s = 270

- 40s = 270 - 280

-40s = -10

s = (-10)/(-40)

s = 1/4

Therefore, there are 1/4 cups of Super Grain Cereal in the mixture

The serving made by Jennifer on Tuesday contains 1/4 cup of Super Grain cereal. Thus, option B is correct.

The mathematical expression is given as the representation of the quantities in terms of variables.

The complete question is given in the image attached below.

The serving of 3/4 cup of Crunchy cereal = 210 calories

The serving of x cup of Crunchy cereal = 210/3/4 * x

The serving of x cup of Crunchy cereal = 280x calories

The serving of 1 cup Super Grain cereal = 240 calories

The serving of y cup of Super Grain cereal = 240y calories

The total serving made by Jennifer on Tuesday = 270 calories

280x + 240y = 270 calories

The serving made by Jennifer = 1 cup

x + y = 1 cup

x = 1 - y

Substituting the value of x in the equation of calorie:

280 (1 - y) + 240y = 270

280 - 280y + 240y = 270

280 - 270 = 280y - 240y

y = 1/4

The serving of super grain cereal made by Jennifer on Tuesday was y cup. Thus, super grain cereal in one cup was 1/4. Hence, option B is correct.
