The unit rate of the silver chain is $0.44 per inch.

What is the unit rate?

Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.

Given here: 16 inches of silver chain costs $36 and 18 inches cost $40.50

Thus we have the unit rate( dollar/inch) =36/16=40.50/18=4/9

Therefore the unit rate is given by 4/9 or 0.444 dollar per inch.

Hence, The unit rate of the silver chain is $0.44 per inch.

Find the slope of the line passing through the points (-9,4) (8,4)

Answers

Answer:

slope = 0

Step-by-step explanation:

1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:

[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]

Thus, the slope is 0.

As we can see in hint through it we can identify that it is right angled triangle so here

AB = 6

FE = BC ( being corresponding sides of congruent triangle)

BC = 8

Now In triangle ABC

perpendicular (p) = 6

base (b) = 8

hypotenuse (h) = ?

By using Pythagoras theorem we get

h = √ p² + b²

= √ 6² + 8²

= √ 100

= 10

So Now

AC = h = 10

The lifespans of gorillas in a particular zoo are normally distributed. The average gorilla lives 20.8 years; the
standard deviation is 3.1 years.
Use the empirical rule (68 – 95 - 99.7%) to estimate the probability of a gorilla living between 11.5 and 27 years.

Answers

If the mean is 20.8, one standard deviation each way is adding and subtracting 3.1, so 17.7 and 23.9 (68% of values)

Two standard deviations adding and subtracting 3.1*2 = 6.2, or 14.6 and 27.

Three standard deviations is 11.5 and 30.1

So we have
11.5 - 14.6 - 17.7 - 20.8 - 23.9 - 27 - 30.1

Going left to 11.5 is 3 standard deviations out, so 99.7/2 = 49.85%

Going right to 27 is 2 standard deviations out, so 95/2 = 47.5%

Add those two % to get 97.32%

This is hard to do without a picture so I hope that helps!
