Fraction numbers are known as numerator and denominator

On a number line, fractions are expressed in points that lie between two integers

The general form of fractions is A /B

Decimal numbers can be changed into mixed or ordinary fractions

Mixed fractions consist of integers and ordinary fractions

Decimal numbers have numbers in the form of thousands. Hundreds, tens, thousandths, hundredths, tenths and ones

The results of the division of decimal numbers with numbers 10,100,1000, 10000 and so on can be determined by shifting the comma to the left according to the number of zeros

If you divide a decimal number, you try to make the divisor an integer

Total fencing/week = 42.6 meters

Monday + Tuesday = 13.45+9.5 meters = 22.95 meters

so for 3 days (Wednesday-Friday) = 42.6 - 22.95 = 19.65 meters

Then on eachof the last three days : 19.65 : 3 = 6.55 meters

The distribution of heights of adult American men is approximately Normal with mean 69 inches and standard deviation 2.5 inches.
nalin [4]

Answer:

option C 13.5%

Step-by-step explanation:

As the heights of adults is normally distributed with mean=69 and standard deviation=2.5 so, the percent of men that are between 64 and 66.5 inches tall can be calculated as

P(64<X<66.5)=P[ (64-69)/2.5<(X-μ)/σ<(66.5-69)/2.5]

P(64<X<66.5)=P(-2<Z<-1)

P(64<X<66.5)=P(-2<Z<0)-P(-1<Z<0)

P(64<X<66.5)=0.4772-0.3413=0.1359

Thus, the percent of men are between 64 and 66.5 inches tall is 13.59%.

If we round the resultant quantity then it will be rounded to 13.6% but considering the given options, option C is most appropriate.
