Answer:
0.139
Step-by-step explanation:
We are given that
Total number of cards=52
n=18
We have to find the probability of drawing at least 7 spades
Total number of spaded in deck of 52 cards=13
Probability of getting spade=
Probability,
Probability of getting no spade=
By binomial theorem of probability

P(x
The probability of drawing at least 7 spades=
The probability of drawing at least 7 spades=0.139
It will take 5.83 hours for the bacteria to reach 1119.
<h3>What is exponential Growth ?</h3>
Exponential growth is when the quantity increases according to the function

It is given in the question that
Initial number of Bacteria is 50
After 3 hours the bacteria has increased to 80
The bacterial growth is an exponential growth


Applying log on both sides
1.6 = 3*k
k = 1.6/3
k = 0.533
if this rate of growth continues, how much more time will it take for the number of bacteria to reach 1119

Therefore it will take 5.83 hours for the bacteria to reach 1119.

But send orange chicken and chow me in and chocolate now STAT 4-2=2
using 3.14 for Pi , since you didn't say what value to use
area = PI x r^2
Area of larger circle = 3.14 x 500^2 = 785,000 square units
area of smaller circles = 3.14 x 1^2 = 3.14 square units
785,000/ 3.14 = 250,000 small circles can fit into larger one
