The health care Jimmy’s employer offers is a fee-for-service plan in which Jimmy and his family must pay for $12,500 in health r

elated services in a calendar year before the insurance company begins to pay. Jimmy and his family have several health related issues that demand $685.00 each month. If one of Jimmy’s children were to become seriously injured at the end of the year, how much would the related health costs need to be in order for the insurance company to assume responsibility? a. $984.58 b. $4,280.00 c. $11,815.00 d. $14,417.92

First of all, let's find what the monthly $685 amounts to after a year. $685 x12 = $8,220. After one year, the family will have spent $8,220 for healthcare. However, the threshold of $12,500 must be reached before claiming any payment from insurance. Therefore, the costs related to Jim's seriously injured child will have to amount to: $12,500 - $8,220 = $4,280. The cost to bear in relation to Jim's injured child must be $4,280 or else he won't be able to claim any refund.

In a semiconductor manufacturing process, three wafers from a lot are tested. Each wafer is classified as pass or fail. Assume t
Angelina_Jolie [31]

Answer:

P(X = 0) = 0.027

P(X = 1) = 0.189

P(X = 2) = 0.441

P(X = 3)= 0.343

Step-by-step explanation:

The probability mass function P(X = x) is the probability that X happens x times.

When n trials happen, for each x \leq n, the probability mass function is given by:

P(X = x) = pe_{n,x}.p^{x}.(1-p)^{n-x}

In which p is the probability that the event happens.

pe_{n,x}, is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:

pe_{n,x} = \frac{n!}{x!}

The sum of all P(X=x) must be 1.

In this problem

We have 3 trials, so n = 3

The probability that a wafer pass a test is 0.7, so p = 0.7

Determine the probability mass function of the number of wafers from a lot that pass the test.

P(X = 0) = (0.7)^{0}.(0.3)^{3} = 0.027

P(X = 1) = pe_{3,1}.(0.7).(0.3)^{2} = 0.189

P(X = 2) = pe_{3,2}.(0.7)^{2}.(0.3) = 0.441

P(X = 3) = (0.7)^{3} = 0.343

)) Matt's bill for breakfast at a restaurant was $91. He left an 18% tip. What was the total
gladu [14]

Answer:

$107.38

Step-by-step explanation:

$91 (the price) multiplied by the percentage 18% (91 x 18 = 1630) (1638/100=16.38 [the tip})

$91 (th original price) + 15.38 (the tip) = $108.38 (final price)

How many cans of paint are needed to cover an area of 2200 square units if one can of paint covers in area 400 square units
sergij07 [2.7K]

Answer:

6

Step-by-step explanation:

You have a total area of 2,200 sq units to cover... and each can of paint covers 400 sq units.  So, you'll need:

2200 sq units / 400 sq units/can = 5.5 cans

In such problems, we always round up, since you will need 5 full cans of paint, and half of a 6th can.

So, in total you will need 6 cans of paint to cover all 2,200 sq units.

3 Ramón makes nectar for a hummingbird feeder by mixing 8 cups of water with 2 cups of sugar. Tiffany makes nectar by mixing 9 c
Butoxors [25]

Answer:

Tiffany's nectar is more sugary

Step-by-step explanation:

Given

Ramon:

Water = 8\ cups

Sugar = 2\ cups

Tiffany

Water = 9\ cups

Sugar = 3\ cups

Required

The nectar with more sugar

To do this, we simply calculate the fraction of sugar in both nectar.

This is calculated as:

Fraction = \frac{Sugar}{Sugar + Water}

For Ramon:

Fraction = \frac{2}{8 + 2}

Fraction = \frac{2}{10} = 0.20

For Tiffany

Fraction = \frac{3}{3 + 9}

Fraction = \frac{3}{12} = 0.25

From the calculations above:

0.25 > 0.20

Hence: Tiffany's nectar is more sugary
