A credit card contains 16 digits between 0 and 9. However, only 100 million numbers are valid. If a number is entered randomly,

marusya05 [52]

Answer:

$P(valid) = 1 * 10^{-8}$

Step-by-step explanation:

Let us first find the number of possible credit card numbers that can be formed with the numbers 0 - 9.

We want to form a 16 digit number out of 10 digits, so, we have:

$N = 10^{16}$

There are $10^{16}$ numbers that can be formed.

There are only 100 million valid numbers ( $100 * 10^6 = 10^8$ ). Let the number of valid numbers be n.

Therefore, the probability of picking a number that is valid is:

P(valid) = n / N

$P(valid) = 10^{8} / 10^{16}\\\\P(valid) = 1 * 10^{-8}$

A circle has its center at the center of a square with 26-inch sides. Using 3.14 for pi, find the area of the square not covered

AlladinOne [14]

For squrae
area=side²
perimiter=4(side)

for circle
area=pir²
circumference=2pir

side=diameter, diameter/2=radius=side/2

find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches

areanotcovered=676-530.66=145.34 square inches not coverd

ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785
