Answer:
List the factors of 450
1,450
3,150
5,90
6,75
9,50
10,45
15,30
18,25
The factor with the sum of 43 is 18+25
25-18=7 so the difference is 7
hope this helps

Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- p = probability of success = 0.4
- q = 1 - p = 0.6
- n = number of trials = 100
P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
<u>Using a binomial probability calculator</u> :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

The probability that has a basic model purchase extended warranty will be 0.1935 or 19.35%.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
A company that manufactures video cameras produces a basic model and a deluxe model.
Over the past year, 45% of the cameras sold have been of the basic model.
Of those buying the basic model, 43% purchase an extended warranty, whereas 50% of all deluxe purchasers do so.
If you learn that a randomly selected purchaser has an extended warranty.
Then the probability that has a basic model purchase extended warranty will be
P = 0.45 × 0.43
P = 0.1935
P = 19.35%
