From the given each urn would contain 10 numbers (that is, from 0 to 9). The total number of sample points in the sample space can be calculated through the fundamental principles of counting. 

We simply multiply the number of numbers in each urn since there is no restriction.
                 sample space = 10 x 10 x 10 = 1000

Thus, there are 1000 possible outcomes for the lottery.

PLEASE HELP FASTTT!!!

Answer:

5 seconds

Step-by-step explanation:

Looking at your function (h(t) = -16t^2 + 48t + 160), I see that the peak height will be 196 feet, and that is achieved in 1.5 seconds.

h(1.5) = -16(1.5)^2 + 48(1.5) + 160

h(1.5) = -16(2.25)+ 48(1.5) + 160

h(1.5) = -36 + 48(1.5) + 160

h(1.5) = -36 + 72 + 160

h(1.5) = 36 + 160

h(1.5) = 196

Going down from that height, it would take 3.5 more seconds, so it would take 5 seconds in total

h(5) = -16(5)^2 + 48(5) + 160

h(5) = -16(25) + 48(5) + 160

h(5) = -400 + 48(5) + 160

h(5) = -400 + 240 + 160

h(5) = -400 + 400

h(5) = 0

Which numbers below are integers but not natural numbers?<br><br> 1, - 5.41,3root12, 0, -3, -9/7,23
m_a_m_a [10]

Answer:

0 and -3

Step-by-step explanation:

Natural numbers are all whole numbers from 1 to infinity. i.e

1, 2, 3, 4 . . .

These numbers do not include 0.

Integers are all whole numbers (positive and negative) including 0. i.e

. . ., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, . . .

These numbers are all natural numbers including their negative counterparts (i.e negatives of the natural numbers) and also 0.

<em>So from the options in the question:</em>

1 is a natural number as well as an integer

-5.41 is not a natural number neither is it an integer.

3 root 12 (written as 3\sqrt{12}) is neither a natural nor an integer number.

0 is an integer but not a natural number

-3 is an integer but not a natural number

-9/7 is neither a natural nor an integer number.

23 is a natural number as well as an integer

Therefore, 0 and -3 are integers but not natural numbers

The safe load, L, of a wooden beam supported at both ends varies jointly as the width, w, and the square of the depth, d, and in
MakcuM [25]

Answer:

joint variation means L (safe load) is directly proportional to both w and d2

inverse proportionality means L = k/l

So the equation is:

L = k(wd2/l)

You are given:

w = 6 in

d = 5 in

l = 12 ft

L = 7666 lbs

7666 = k(6*52/12)

Solve for the constant, k.

7666 = k (6*25/12)

7666 = k (150/12)

7666 = k (12.5)

613.28 lbs/(ft.in3) = k

Use this k-value to solve for L in the last part of the question.

What safe load, L would a beam 3 in. wide, 7 in. deep and 15 ft long of the same material support? (Round off your answer to the nearest pound.)

w = 3 in

d =7 in

l = 15 ft

k = 613.28 lbs/(ft.in3)

Final Safe load = 6010.144 lbs *** Edited for clarity and to fix a multiplication erro
