Answer:

Expected_A  = 1.36

Expected_B  = 1.54

Company A, as it has the lowest expected number of defective boards

Step-by-step explanation:

What is the expected number of defective circuit boards for company A?

To obtain this value, we multiply the probabilities of each, per the number of defective circuit boards

Expected_A = 0*(0.21) + 1*(0.3) + 2*(0.41) + 3*(0.08)

Expected_A  = 1.36

What is the expected number of defective circuit boards for company B?

Expected_B = 0*(0.18) + 1*(0.32) + 2*(0.28) + 3*(0.22)

Expected_B  = 1.54

Which company should be chosen for purchasing circuit boards?

Company A, as it has the lowest expected number of defective boards

Rose is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away
tensa zangetsu [6.8K]

The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise.

Answer:

Kindly check explanation

Step-by-step explanation:

If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.

Hypotenus² = opposite² + adjacent²

(refer to attached picture)

x² = 6² + 8²

x² = 36 +. 64

x² = 100

x = sqrt(100)

x = 10 meters

You can use the actual depth value to obtain the actual solution to your question.

What multiplication problem is equivalent to 3 3/8 divide by 3/8
Anni [7]

The expression 3\frac{3}{8}\div \frac{3}{8} can be written in multiplication problem as: 3\frac{3}{8}\times \frac{8}{3} or \frac{27}{8}\times \frac{8}{3}

Step-by-step explanation:

We need to find What multiplication problem is equivalent to 3\frac{3}{8}\div \frac{3}{8}

We are given: 3\frac{3}{8}\div \frac{3}{8}

Writing it in multiplication problem.

When division sign is changed to multiplication sign, the fraction is reciprocated.

3\frac{3}{8}\div \frac{3}{8}

Converting division into multiplication

3\frac{3}{8}\times \frac{8}{3}

or we can write as:

\frac{27}{8}\times \frac{8}{3}

So, the expression 3\frac{3}{8}\div \frac{3}{8} can be written in multiplication problem as: 3\frac{3}{8}\times \frac{8}{3} or \frac{27}{8}\times \frac{8}{3}

There were 2,626,418 deaths in 2014 according to the CDC. 614,348 of these deaths were caused by diseases of the heart and 136,0
Alex777 [14]

Answer:

= 0.714 (in decimal fraction)

The probability that the death in 2014 was not caused by heart diseases or Unintentional Injuries = 0.714

= 0.714

Step-by-step explanation:

Let's interpret the question our way ti solve it .

Total deaths in 2014:

2626418

Death caused by Heart Diseases:

614348

Death caused by Unintentional Injuries:

750401

Therefore, we can deduced that, the number of death not caused by Heart Diseases or Unintentional Injuries = Total deaths in 2014 minus sum of the recorded death.

= 2626418 - ( 614348 + 136053)

= 2626418 - 750401

= 1876017.

Now, the probability that there were death in 2014 is 1 (one)

To find the probability that death we're not caused by heart diseases or Unintentional Injuries:

= 1 - Pr (Death Caused by heart diseases) + Pr (Death causes by Unintentional Injuries)

= 1 - (0.234 + 0.052)

= 1 - 0.286

= 0.714

To Check:

= 1876017 / 2626418

Divide to the lowest term

=0.714
