David made a scale drawing of an Olympic-sized pool the pool is 20.5 in long and the drawing that I can shoot pool is 164 ft lon

SIZIF [17.4K]

Answer:

$Scale = 1\ in : 8\ ft$

Step-by-step explanation:

Given

$Scale\ Measurement = 20.5in$

$Actual\ Measurement = 164ft$

Required

Determine the scale

The scale is calculated using the following ratio:

$Scale = Scale\ Measurement : Actual\ Measurement;$

Substitute values for Scale and Actual Measurements

$Scale = 20.5\ in : 164\ ft$

Divide ratio by 20.5

$Scale = 20.5/20.5\ in : 164/20.5\ ft$

$Scale = 1\ in : 8\ ft$

This implies that: <em>1 inch on scale represents 8 ft in actual measurement</em>

Simplify the expression.

levacccp [35]

Hi there! The answer is 30.

We need to use PEMDAS to simplify.
P = parenthesis
E = Exponents
M = Multiply
D = Dividing
A = Adding
S = Subtracting

$10(4 \times 10 \div ( {6}^{2} - {4}^{2} ) + 1)$
First find the exponents inside the middlest parenthesis.

$10(4 \times 10 \div (36 - 16) + 1)$
Now add inside the parenthesis.

$10(4 \times 10 \div 20 + 1)$
Multiply inside the parenthesis that are left.

$10(40 \div 20 + 1)$
Divide inside the parenthesis

$10(2 + 1)$
Add inside the parenthesis.

$10(3)$
Multiply.

$30$
~ Hope this helps you!

The number of defective units in a production run of 850 circuit boards are normally distributed with 21 defective units and 3 d

Katen [24]

Answer:

82%

Step-by-step explanation:

We let the random variable X denote the number of defective units in the production run. Therefore, X is normally distributed with a mean of 21 defective units and a standard deviation of 3 defective units.

We are required to find the probability, P(17 < X < 25), that the number of defective units in the production run is between 17 and 25.

This can be carried out easily in stat-crunch;

In stat crunch, click Stat then Calculators and select Normal

In the pop-up window that appears click Between

Input the value of the mean as 21 and that of the standard deviation as 3

Then input the values 17 and 25

click compute

Stat-Crunch returns a probability of approximately 82%
