What is the value of y2 – x2 when y = 6 and x = 5?

Papessa [141]

Answer:

y^2 - x^2 = 11

Step-by-step explanation:

y^2 - x^2 = ?

Substitute.

y = 6

x = 5

Becomes:

6^2 - 5^2 = ?

Solve.

6^2 = 6 x 6

6 x 6 = 36

5^2 = 5 x 5

5 x 5 = 25

36 - 25 = 11

In a random sample of 64 people, 48 are classified as 'successful.' Determine the sample proportion of 'successful' people.

hichkok12 [17]

Answer:

The sample proportion of 'successful' people is $\frac{3}{4}$ .

Step-by-step explanation:

The sample consist of 64 people and 48 of them are 'successful'. Hence, the proportion of 'successful' people is:

$p = \frac{n}{N}$

Where:

$N$ - People that forms the sample, dimensionless.

$n$ - People classified as 'successful', dimensionless.

Given that $n = 48$ and $N = 64$ , the sample proportion of 'successful' people is:

$p = \frac{48}{64}$

$p = \frac{3}{4}$

The sample proportion of 'successful' people is $\frac{3}{4}$ .
