Answer:

0.375 pounds of melon was given away by Melanie.

Step-by-step explanation:

We are given the following in the question:

Initial weight of melon =

$1\dfrac{1}{8}\text{ pounds}$

Wait of remaining piece =

$\dfrac{6}{8}\text{ pounds}$

Pounds of melon Melanie gave away =

Initial weight of melon - Wait of remaining piece

$= 1\dfrac{1}{8} - \dfrac{6}{8}\\\\=\dfrac{9}{8}-\dfrac{6}{8}\\\\=\dfrac{3}{8} = 0.375\text{ pounds}$

Thus, 0.375 pounds of melon was given away by Melanie.

250 students were asked to choose their favorite color. How many more students chose purple than red as their favorite color? 26

nevsk [136]

Answer:

10 more students chose purple than red as their favorite color

Step-by-step explanation:

Step 1

Determine the proportion of students that chose each color

purple=26%

red=22%

Step 2

Use the expression for the number of students per color as follows;

Number of students per color=proportion per color×total number of students

for purple;

proportion that chose purple=26%

total number of students=250

replacing;

Number of students that chose purple=(26/100)×250=65 students

for red;

proportion that chose red=22%

total number of students=250

replacing;

Number of students that chose purple=(22/100)×250=55 students

Step 3

Difference=65-55=10

10 more students chose purple than red as their favorite color

Let x be a random variable with pmf pk = c/k2 for k = 1, 2, …a. estimate the value of c numerically. note that the series conver

kaheart [24]

$f_X(x)=\begin{cases}\dfrac c{k^2}&\text{for }k\in\{1,2,\ldots\}\\0&\text{otherwise}\end{cases}$

Because this is a valid PMF, you must have

$\displaystyle\sum_{k\ge1}f_X(x)=\sum_{k\ge1}\frac c{k^2}=1$

Recall that

$\displaystyle\sum_{k\ge1}\frac1{k^2}=\dfrac{\pi^2}6$

so the above sum is

$\displaystyle\sum_{k\ge1}\frac c{k^2}=\frac{c\pi^2}6=1$

which means that you must have

$c=\dfrac6{\pi^2}\approx0.6079$
