Answer:
1) The quotient of r and 0.2 is equal to 40.
2) r divided by 0.2 is equal to 40.
We should first calculate the average number of checks he wrote
per day. To do that, divide 169 by 365 (the number of days in a year) and you get (rounded) 0.463. This will be λ in our Poisson distribution. Our formula is

. We want to evaluate this formula for X≥1, so first we must evaluate our case at k=0.

To find P(X≥1), we find 1-P(X<1). Since the author cannot write a negative number of checks, this means we are finding 1-P(X=0). Therefore we have 1-0.3706=0.6294.
There is a 63% chance that the author will write a check on any given day in the year.<em />

Answer:
#4.
- 3 < - 2 1/2
If you consider the number line, the numbers increase from left to right. The number on the left is smaller than a number on the right.
- 3 is smaller than -2 1/2, it means -3 is on the left from the -2 1/2 on the number line.
#5.
Jada's score is positive, it means the number reflecting the score is to the right from zero on the number line.
Isabel's score is negative, it means the number reflecting the score is to the left from zero on the number line.
Since Isabel's score is to the left from the Jada's score, she has lower score than Jada.
With the lowest score, Isabel is the winner.
Answer:
x = 5/6
Step-by-step explanation:
From the question, we are told that the value of the perimeter equals the value of the area
mathematically, the area of a rectangle is the product of its side lengths
we have this as;
5 * 4x = 20x
The formula for the perimeter is;
P = 2(l + b)
P = 2(5 + 4x)
So we equate this to the area above
20x = 2(5 + 4x)
20x/2 = 5 + 4x
10x = 5 + 4x
10x - 4x = 5
6x = 5
x = 5/6
