$(36)/(54)=(36:18)/(54:18)=(2)/(3)\n\n(47)/(n)=(2)/(3)\ \ \ |cross\ multiply\n\n2\cdot n=3\cdot47\n\n2n=141\ \ \ \ |divide\ both\ sides\ by\ 2\n\nn=(141)/(2)\n\n\boxed{n=70.5}$

$47/n = 36/54$

$47/n=2/3$

$47=2/3n$

$47=2n/3$

$47*3=2n$

$141=2n$

$141/2=n$

Evaluate. 103 • [12 ÷ (10 – 4 • 2)] + 3

Answers

103 • [12 ÷ (10 – 4 • 2)] + 3

PEMDAS. We need to take care of the parenthesis, first.

103 • [12 ÷ (10 – 4 • 2)] + 3

Inside the parenthesis, we must do the other parenthesis inside and follow PEMDAS in there.

103 • [12 ÷ (10 – 8)] + 3
103 • [12 ÷ (2)] + 3
103 • [12 ÷ 2] + 3
103 • [6] + 3
103 • 6 + 3

Now, we can do multiplication.

103 • 6 + 3
618 + 3
621

Your final answer is 621.

A shipment of marbles with a mean diameter of 27 mm and a standard deviation of 0.15 mm is normally distributed. By how many standard deviations does a marble with a diameter of 26.85 mm differ from the mean?

Answers

This could be solved by calculating the z-score. Itsdefinition is the number of standard deviations from the mean a data point is.The formula is,

Z =║Data point – Mean║ / Std. dev.

Z = ║26.85 mm – 27 mm║ / 0.15

Z = 1

Answer:

The answer would be 1
