15. A manufacturer of electronic calculators is interested in estimating the fraction of defective units produced. A random samp

Answer:

220 items must be sold to achieve break-even.

Step-by-step explanation:

550 + 3.00x = 5.50x

550 = 2.50x

220 = x

The weight corresponding to the 40th percentile is 182.41 pounds.

The question appears to be incomplete. Here’s the complete inquiry:

Samir is quite skilled with the gun. When he targets a specific aim at the shooting range, he has a 0.95 probability of striking it. On one occasion, Samir sets out to shoot 10 targets consecutively.

If he has the same chance of hitting each of the 10 targets, what is the likelihood that he will miss at least one?

Response:

40.13%

Step-by-step breakdown:

Let 'A' represent the event of successfully hitting all targets in 10 trials.

The complement of 'A' is

Now, since Samir has a consistent probability of hitting each target at 0.95.

Now,

We know that the combined probability of an event and its complement equals 1.

<pThus,

Consequently, the probability that he misses at least one target among 10 attempts is 40.13%.

Greetings from MrBillDoesMath! The answer is: 669/221 Discussion: The ratio of 669 to 221 equals 669/221. Observing the factors, 669 is 3 * 223 and 221 is 13 * 17. As all these factors are distinct primes, nothing cancels in their ratio. Thus, 669/221 remains in its simplest form.
