Considering the mean and range concepts, it is found that the correct option is:

C. On average, Athens have a higher temperature. However, temperatures in Madrid vary more.

<h3>What are the mean and the range of a data-set?</h3>
  • The mean of a data-set is given by the sum of all observations divided by the number of observations.
  • The range is given by the subtraction of the highest value by the lowest.

In this problem, Athens has a higher mean, while Madrid has a higher range, hence the correct option is:

C. On average, Athens have a higher temperature. However, temperatures in Madrid vary more.

Naya [18.7K]

Answer:

\frac{51}{8} cups.

Step-by-step explanation:

It is given that the ingredients for making chocolate cookies are \frac{3}{4} cup of brown sugar, \frac{1}{4} cup of white sugar, \frac{3}{2} cup of butter, \frac{11}{8} cup of flour, and \frac{5}{2} cup of chocolate chips.

Now, we have to calculate the total number of cups of ingredients needed in making chocolate cookies.

So, it will be given by

(\frac{3}{4} + \frac{1}{4} + \frac{3}{2} + \frac{11}{8} + \frac{5}{2}) cups

= \frac{3 \times 2 + 1 \times 2 + 3 \times 4 + 11 + 5 \times 4}{8} cups

= \frac{51}{8} cups. (Answer)

On a biased dice the probability of getting 1 is 0.3. The ice is rolled 150 times. How many ones would you expect to roll?
Montano1993 [528]

Answer:  45

=====================================================

Work Shown:

n = number of rolls = 150

p = probability of rolling a "1" = 0.3

n*p = expected number of "1"s that show up out of the 150 rolls

n*p = 150*0.3

n*p = 45

We expect about 45 ones will show up.

Factor completely 2x^2 − 2x − 40. 2(x − 5)(x 4) (2x − 10)(x 4) (x − 5)(2x 8) 2(x − 4)(x 5)
Zina [86]
2x^2 - 2x - 40 = 2x^2 -10x + 8x - 40 = 2x(x - 5) + 8(x - 5)

= (x-5)(2x+8) = 2(x-5)(x+4)
