Answer:
The expected cost of the company for a 3000 tires batch is $120255
Step-by-step explanation:
Recall that given a probability of defective tires p, we can model the number of defective tires as a binomial random variable. For 3000 tires, if we have a probability p of having a defective tire, the expected number of defective tires is 3000p.
Let X be the number of defective tires. We can use the total expectation theorem, as follows: if there are 
events that partition the whole sample space, and we have a random variable X over the sample space, then
.
So, in this case, we have the following
.
Let Y be the number non defective tires. then X+Y = 3000. So Y = 3000-X. Then E(Y) = 3000-E(X). Then, E(Y) = 2949.
Finally, note that the cost of the batch would be 40Y+45X. Then
1) vertical line
2) neither
3) horizontal line
4) neither- these two overlap.

5 through 6 equation: a²+b²=c²
5) 5²+.8²=c²
25+.64=c²
√25.64=√c²
√25.64=C or 5.063=C
6) 2²+8²=c²
4+64=c²
√68=√c²
√68=C or 8.246=C

It's 26×10×10×10 because there are 26 possibilities (a-z) for the first letter and 10 possibilities (0-9) for each number. That makes the answer 26,000.
We conclude that after 50 days, there will be 67 lily pads.
<h3>how many will there be after 50 days?</h3>
We know that the number increases by 25% every 10 days.
In 50 days we have 5 groups of 10 days, so there will be five increases of 25%.
We know that the initial number is 22 lily pads, if we apply five consecutive increases of the 25% we get:
N = 22*(1 + 25%/100)*...*(1 + 25%/100%)
( the factor (1 + 25%/100%) appears five times)
So we can rewrite:
N = 22*(1 + 25%/100%)⁵
N = 22*(1 + 0.25)⁵ = 67.1
Which can be rounded to the nearest whole number, which is 67.
So we conclude that after 50 days, there will be 67 lily pads.
