The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.

To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.

A random sample of the closing stock prices in dollars for a company in a recent year is listed below. Assume that sigma is $2.

Answer:

[ 17.8941, 19.6621]

Step-by-step explanation:

Given:

widths :

18.41 19.11 18.67 18.97 21.97 17.26 18.69 16.73 21.97 16.43 21.97 21.66 18.77 17.93 15.47 16.44

Total number of observations = 16

Mean of the sample = $\frac{\textup{Sum of observations}}{\textup{Total number of observations}}$

= $\frac{\textup{300.45}}{\textup{16}}$

= 18.7781

For 90% confidence level, z value = 1.645

Therefore,

Margin of error, E = $z\frac{\sigma}{\sqrt n}$

= $1.645\times\frac{2.15}{\sqrt{16}}$

= 0.884

thus,

Confidence interval = Mean ± E

or

Confidence interval = [18.7781 - 0.884 , 18.7781 + 0.884 ]

= [ 17.8941, 19.6621]
