Required

Complete the blanks

To do this, we simply carry out the division operation.

So, we have:

$\frac{47}{2} \to 6$

$\frac{60}{12} \to 5$

$\frac{40}{10} \to 4$

$\frac{56}{8} \to 7$

Suppose the distribution of home sales prices has mean k300, 000 and standard

777dan777 [17]

<u>Given</u>:

Mean,

$\mu = 300,000$

Standard deviation,

$\sigma = 50,000$

The Chebyshev theorem will be used for the solution of the given query,

i.e., $P(|X - \mu| < k \sigma ) \geq 1-\frac{1}{k^2}$

(i)

⇒ $1-\frac{1}{k^2} = 0.75$

$k = 2$

The lower limit will be:

= $\mu - k \sigma$

= $300000-2\times 50000$

= $200000$

The upper limit will be:

= $\mu + k \sigma$

= $300000+2\times 50000$

= $400000$

hence,

The 75% houses sold are between:

⇒ (200000, 400000)

(ii)

⇒ $\mu -k \sigma = Lower \ limit$

By putting the values, we get

$300000-50000k = 150000$

$300000-150000=50000k$

$150000=50000k$

$k=\frac{150000}{50000}$

$=3$

now,

⇒ $1-\frac{1}{k^2} = 1-\frac{1}{3^2}$

$=\frac{8}{9}$

$=0.8888$

$=88.88$ (%)

hence,

88.88% houses sold between 150000 and 450000.

(iii)

⇒ $\mu - k \sigma = Lower \ limit$

By putting the values, we get

$300000-50000k = 170000$

$300000-170000=50000 k$

$130000= 50000 k$

$k = \frac{130000}{50000}$

$=2.6$

now,

⇒ $1-\frac{1}{k^2} = 1-\frac{1}{2.6^2}$

$=0.8521$

$=85.21$ (%)

hence,

85.21% houses are sold between 170000 and 430000.

Tanya [424]

each bowl of ice crem creats a profit of $0.35

For the profit made with 3/4 bowl of icecream : multiply 3/4 by $0.35

$\begin{gathered} \text{ Profit for the }\frac{3}{4}\text{ bowl of icecream=}\frac{3}{4}\times0.35 \\ \text{ Profit for the }\frac{3}{4}\text{ bowl of icecream=}0.2625\text{ } \end{gathered}$

Profit made by 3/4 bowl of icecream is $0.2625
