Answer:
91 push-ups
Step-by-step explanation:
The probability that both of them have the secret decoder ring will be 0.1305.
Inside the box of every cereal box contains a surprise gift.
The store manager assures employees that 22 of the 60 boxes on the shelf have a secret decoder ring.
And inside the other 38 boxes on the shelf contain a different gift.
If two cereal boxes are randomly selected from the shelf to purchase.
Then the probability that both of them have the secret decoder ring will be
The total events will be
Total event = ⁶⁰C₂
Total event = 1770
The favorable events will be
Favorable event = ²²C₂
Favorable event = 231
Then the probability will be
P = 231/1770
P = 0.1305

Answer:
exact arc length = 21pi
approximate arc length (using calculator) = 65.9734457253857
approximate arc length (using 3.14 for pi) = 65.94
units are in feet
============================================
Work Shown:
L = (x/360)*2*pi*r
L = (315/360)*2*pi*12
L = 21pi = exact arc length in terms of pi
If you use your calculator's stored version of pi, then L is approximately
L = 21pi
L = 65.9734457253857
Or if you end up using pi = 3.14, then
L = 21*pi
L = 21*3.14
L = 65.94
Fairly close to the other approximation though a bit off because pi = 3.14 is just a rough approximation.

Step-by-step explanation:
A culture of bacteria grows exponentially according to the following general exponential growth function;
where;
p(t) is the population at any given time t.
p(0) is the initial population
k is the growth constant
From the information given we have;
p(0) = 1500
at t = 5, p(t) = 2300; p(5) = 2300
We shall use this information to determine the value of k;
Divide both sides by 1500;
Therefore, the population of the bacteria at any time t is given by;
