I'm not sure exactly what you are trying to ask, but you can multiply the numerator and denominator by any number and it will stay the same value fraction, as long as you are multiplying them both by the same number.

Multiply both 3 and 7 by 2, this gives you equivalent fractions (there are more possible equivalent equations of course)

If △NMO ∼ △XYZ, and the area of △NMO is 147 square feet, find the area of △XYZ

sladkih [1.3K]

The area of △XYZ according to the figure is 363ft²

<h3>Area of triangles</h3>

The formula for calculating the area of a triangle is expressed as:

A = 0.5bh

b is the base
h is the height

<h3>Calculate area of each triangles</h3>

For the triangle △NMO

Area of △NMO = 0.5bh

147 = 0.5b(14/12)

147 = 7b/12

7b = 12 * 147

b = 252

b = 252ft

b = 3024in

Get the base of △XYZ

14/3024 = 22/XZ

XZ = 4,752in

Area of △XYZ = 0.5 (4,752)(22)

Area of △XYZ= 52,272in²

Area of △XYZ = 363ft²

Hence the area of △XYZ is 363ft²

The length of time a person takes to decide which shoes to purchase is normally distributed with a mean of 8.54 minutes and a st

Minchanka [31]

Answer:

0.0323 = 3.23%. Is unusual

Step-by-step explanation:

Using the normal distribution we can find z value with the mean and standard deviation as follows. x is the value we want to know its probability

z = (x - mean)/standard deviation

z = (5-8.54)/1.91

z = -1.85

Using z tables for normal distribution, for z = 1.85, we have an area under the curve of 0.9677. Since we want to know the probability for 5 minutes or less, we have to substract from

p = 1- 0.9677

p = 0.0323

An event with a probability less than 5% is considered unusual.
