Answer:

ornament area = 379.8 cm²paint needed: 114 bottles

Step-by-step explanation:

The surface area of one cone with slant height s and radius r is ...

  SA = πr² +πrs = πr(r+s)

For the cone that is half an ornament, the surface area is ...

  SA = (3.14)(4.2 cm)(4.2 cm + 10.2 cm) = 189.9072 cm²

The area of one ornament is the area of two cones:

  one ornament area = 2×189.9072 cm² ≈ 379.8 cm²

60 ornaments will be 120 cones, so will have a total surface area of ...

  total area = 120(189.9072 cm²) = 22,788.864 cm²

__

If one bottle of paint will cover 201 cm², then the number of bottles of paint required is ...

  (22788.864 cm²)/(201 cm²/bottle) ≈ 113.4 bottles

Step-by-step explanation:

In Prof. Leahy's class, if a student does homework most days, the chance of passing the course is 90%. On the other hand, if a student does not do homework most days, the chance of passing the course is only 30%. Prof. Leahy claims that 70% of his students do homework on a regular basis. If a student is chosen at random from Prof. Leahy's class, find the following probabilities:

a. p(the student did not do homework and he/she passed the course)
b. p(the student did not do homework given that she/he passed the course)

Answers

Answer:

a) p(the student did not do homework and he/she passed the course) = 0.09

b) p(the student did not do homework given that she/he passed the course) = 0.125.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

a. p(the student did not do homework and he/she passed the course)

If a student does not do homework most days, the chance of passing the course is only 30%. 100 - 70 = 30% don't do homework on a regular basis.

So

0.3*0.3 = 0.09

p(the student did not do homework and he/she passed the course) = 0.09

b. p(the student did not do homework given that she/he passed the course)

Conditional probability.

Event A: Passed the course

Event B: Did not do homework.

p(the student did not do homework and he/she passed the course) = 0.09

This means that [tex]P(A \cap B) = 0.09[/tex]

Probability that the student passes the course:

90% of 70%(do homework)

30% of 30%(do not do homework).

This means that:

[tex]P(A) = 0.9*0.7 + 0.3*0.3 = 0.72[/tex]

p(the student did not do homework given that she/he passed the course)

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.09}{0.72} = 0.125[/tex]

So

p(the student did not do homework given that she/he passed the course) = 0.125.

A company that manufactuers small canoes has a fixed cost of $14,000. It cost $40 to produce each canoe. The selling price is $80 per canoe

Answers

Answer:

The company manufactures about 350 canoes, obtaining $ 28,000 after selling them all.

Step-by-step explanation:

Given that a company that manufactures small canoes has a fixed cost of $ 14,000, and it cost $ 40 to produce each canoe while the selling price is $ 80 per canoe, to determine the number of canoes that the company produces and the amount of money it makes after selling them, the following calculation must be carried out:

14/000 / 40 = X

350 = X

350 x 80 = 28,000

Thus, the company manufactures about 350 canoes, obtaining $ 28,000 after selling them all.

Answer:

  5 ft

Step-by-step explanation:

You are given the area and base lengths of a trapezoid and asked for its height. The formula for the area of a trapezoid is useful.

  A = (1/2)(b1 +b2)h

Filling in the given information, you have ...

  30 ft² = (1/2)(4 ft +8 ft)h

  30 ft² = (6 ft)h . . . . . . . . . . . simplify

  h = (30 ft²)/(6 ft) = 5 ft . . . . divide by the coefficient of h

The height of the trapezoid is 5 feet.
