How much sand would you need to fill this box ?

grin007 [14]

Step-by-step explanation:

We have,

l =5ft

b=2ft

h=3ft

$volume(v) = l \times b \times h$

v = (l*b*h)

v = (5*2*3)ft

v = (30)ft

.•. v = 30ft

Find all polar coordinates of point P where P = ordered pair 1 comma pi divided by 3.

baherus [9]

Answer:

(1, π/3 +2kπ), (-1, 4π/3 +2kπ) . . . where k is any integer

Step-by-step explanation:

Adding any multiple of 2π to the angle results in the same point in polar coordinates.

Adding 180° (π radians) to the point effectively negates the magnitude. As above, adding any multiple of 2π to this representation is also the same point in polar coordinates.

There are an infinite number of ways the coordinates can be written.

A polling organization asked a nation-wide random sample of 1600 new brides (those who got married in the past 2 years) the foll

iren [92.7K]

Answer:

It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.

Step-by-step explanation:

Given that:

sample size n = 1600

sample mean $\overline x$ = 20000

standard deviation = 5000

The objective is to choose from the given option about what most closely resembles the relevant box model.

The correct answer is:

It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.

However, if draws are made without replacement, the best estimate of the average amount for the bride will be $20,000

Similarly, the standard error for the sample mean = $\dfrac{s}{\sqrt{n}}$
