C like circumference:
C = 2 π * r = 2 * 3,14 * 3,5 = 21,99 ≈ 22 m

A like area:
A = π r² = 3,14 * (3,5)² = 3,14 * 12,25 = 38,48 m

The profit y (in dollars) for a business from selling x coats is represented by y=56x . Graph the equation.

Agata [3.3K]

Answer:

The graph of the equation is also attached.

From the graph, it is clear that at x = 0, the value of y = 0

Hence, the line passes through the origin with the y-intercept 0.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the slope

b is the y-intercept

Given that the profit y (in dollars) for a business from selling x coats is represented by the equation

$y=56x$

comparing with the slope-intercept form of the line equation

m = 56

Determining the y-intercept

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

substitute x = 0 in the equation

y = 56(0)

y = 0

Thus, the y-intercept b = 1

Thus,

The equation y = 5x has:

The slope m = 56

The y-intercept b = 1

The graph of the equation is also attached.

From the graph, it is clear that at x = 0, the value of y = 0

Hence, the line passes through the origin with the y-intercept 0.

Leto [7]

Answer:

0.54,0.46,0.43

Step-by-step explanation:

Given that India is the second most populous country in the world, with a population of over 1 billion people.

The pdf of household size say X in India varies from 1 to 8.

The distribution is shown as follows

X 1 2 3 4 5 6 7 8 Total

P 0.02 0.09 0.18 0.25 0.20 0.12 0.08 0.06 1.00

a) the probability that there are less than 5 members in a household in India

= $P(X$

= $P(1 to 4) = 0.54$

b. the probability that there are 5 or more members in a typical household

in India

= $P(X\geq 5) = P(5 to 8)\\\\= =0.46$

c) the probability that the number of members in a typical household in India is strictly between 2 and 5

$=P(2$

Write an recursive formula for An, the nth term of the sequence 5, -2, -9,

oksian1 [2.3K]

Given:

The given sequence is:

$5,-2,-9,...$

To find:

The recursive formula for $a_n$ , the nth term of the sequence.

Solution:

We have,

$5,-2,-9,...$

Here, the first term is 5.

$-2-5=-7$

$-9-(-2)=-9+2$

$-9-(-2)=-7$

The common difference is -7.

The recursive formula for the nth term of the sequence is

$a_n=a_{n-1}+d$

Where, $d$ is the common difference.

Putting $d=-7$ in the above formula, we get

$a_n=a_{n-1}+(-7)$

$a_n=a_{n-1}-7$

Therefore, the recursive formula for the nth term of the sequence is $a_n=a_{n-1}-7$ .
