The perimeter of a rectangular window is 264 cm.
If the width of the window is 56 cm, what is its length?

Answers

Answer:

length = 76 cm

Step-by-step explanation:

The perimeter = (2 × width) + (2 × length)

264 = (2×56) + (2 × length)

264 = 112 + (2 × length)

264 - 112 = 2 × length

152 = 2 × length

152/2 = length

76 = length

length = 76 cm

A woman invested $15,000 part in 7% stocks and the remainder in 9% bonds. If her yearly yield from both investments is $1,230.00, how much did she invest at each rate?

Answers

Using the simple interest relation, the amount invested in stocks and bond respectively is $15,000 and $2000

Simple interest

Principal × rate × time

Let her total principal = p

Stock :

Interest = 15000 × 0.07 × 1 = 1050

Bond :

Interest = (p - 15000) × 0.09 = 0.09p - 1350

Total interest earned :

1050 + 0.09p - 1350 = 1230

-300 + 0.09p = 1230

0.09p = 1230 + 300

0.09p = 1530

p = $17000

Hence,

Amount invested in stock at 7% = $15000

Amount invested in bond at 9% = $17000 - 15000 = $2000

The average person’s speed when riding a bike along a street is 18 kilometers per hour. What conversion factor can be used to convert this speed to meters per hour?

StartFraction 1 meter Over 1,000 kilometers EndFraction
StartFraction 1,000 meters Over 1 kilometer EndFraction
StartFraction 1,000 kilometers Over 1 meter EndFraction

Answers

Answer:

The given average speed =  18 km per hour

Now, as we know from the conversion parameters:

 1000 meters   = 1 km

or 1 meter =  ( 1/ 1000) kilometer

So, we can use the above information to convert average speed into meters per hour.

The given speed =  18 km / hr = 18 x (1000) meters /hr

                            = 18,000 meters / hr

Suppose that an airline overbooks seats on their flights. In particular, it sells 300 tickets for a flight when there are only 270 seats available. On average, we expect 15% of those with tickets to not show up. What is the probability that we will have enough seats for everyone who shows up

Answers

Using the normal approximation to the binomial, it is found that there is a 0.994 = 99.4% probability that we will have enough seats for everyone who shows up.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean.  After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].

In this problem:

15% do not show up, so 100 - 15 = 85% show up, which means that [tex]p = 0.85[/tex].300 tickets are sold, hence [tex]n = 300[/tex].

The mean and the standard deviation are given by:

[tex]\mu = np = 300(0.85) = 255[/tex]

[tex]\sigma = \sqrt{np(1-p)} = \sqrt{300(0.85)(0.15)} = 6.185[/tex]

The probability that we will have enough seats for everyone who shows up is the probability of at most 270 people showing up, which, using continuity correction, is [tex]P(X \leq 270 + 0.5) = P(X \leq 270.5)[/tex], which is the p-value of Z when X = 270.5.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{270.5 - 255}{6.185}[/tex]

[tex]Z = 2.51[/tex]

[tex]Z = 2.51[/tex] has a p-value of 0.994.

0.994 = 99.4% probability that we will have enough seats for everyone who shows up.
