Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Mashutka [201]

Step-by-step explanation:

The dot is called a decimal point. It is also called the decimal separator. It separates whole numbers from fractional numbers.

In this example;

24.671

The numbers before the point, 24 is the whole number

The numbers after the point, 671 are the fractional portion of the number. They represent 6 tenths, 7 hundredths and 1 thousandths.

Also, the number of digits after the point tells you how many decimal place the number is in. In this example the number of decimal places is 3.

A different species of cockroach has weights that follow a normal distribution with a mean of 50 grams. after measuring the weig

Finger [1]

Given:
μ = 50 g, the mean
Let σ = the standard deviation.

For the random variable x =55 g, the z-score is
z = (55 - 50)/σ

We know that P(x > 55) =0.14 (14%).
From standard tables,
P(x > 55) = 0.14 => z = 0.36 (see the figure below).

Therefore
(55 - 50)/σ = 0.36
5/σ = 0.36
σ = 13.9

Answer: 13.9 grams
