Answer:

10 x 10 = 100 so the area of 1 side is 100

there is 6 sides and the surface area is all the areas added up

he pulse rates of 179 randomly selected adult males vary from a low of 43 bpm to a high of 115 bpm. Find the minimum sample size
malfutka [58]

Answer:

97

Step-by-step explanation:

Given that:

Low = 43bpm

High = 115 bpm

Error = 3

α = 90%

To find the range estimate :

Standard destviation = (high - low) / 4

Standard deviation = (115 - 43) / 4

Standard deviation = 72/4 = 18

The sample size,(n) :

n = [(Zα/2 * sd)/E] ²

2 - tail = (Zα/2) = 1.645

[(Zα/2 * sd)/E] ² = [(1.645 * 18) / 3]² = (29.61/3)²

= 97.41

Sample size = 97

What is the volume of a square pyramid with base edges of 60 inches and a height of 10 inches?
vichka [17]

Answer:

The volume is 12000 in^3

Step-by-step explanation:

From the question ,

L= 60\:in. and H=10\:in.

The volume of a pyramid is given as

V=\frac{1}{3} \times area\:of\:the\:base \times height

From the question, the base of the pyramid is a square.

Hence base area is given by L^{2}

This implies that the volume of the pyramid is

=\frac{1}{3} \times L^{2}\times H

=\frac{1}{3}\times 60^{2} \times 10

=\frac{36000}{3}

=12000 in^3

Serial numbers for a product are to be made using 2 letters followed by 3 numbers. If the letters are to be taken from the first
Daniel [21]
2 Letters chosen among 6 with no repeat:
a) the first has 6 ways
    the second has 5  ways

Then to choose 2 letters among 6, with no repeat, there are 6x5 = 30 ways

 b) 3 numbers are taken from the digits 0 through 9 with repeats (total = 10)
     the first has 10 ways
     the second has 10  ways
    the third has 10  ways

Then to choose 3 numbers among 10, with repeat, there are 10x10x10= 1000 ways
And the total serial numbers that can be generated is
30 x 1000 = 3000
