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

Answer 1
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!

I NEED HELP!!! PLS

Answers

Answer:

m∠Y=50°

Step-by-step explanation:

So, we know that ∠S+∠Y=90 and that m∠S=2(m∠Y)-60.

If you plug those things into the equation, you get (2[m∠Y]-60)+m∠Y=90.

Then you multiply 2 and m∠Y: 2m∠Y-60+m∠Y=90.

Combine like terms: 3m∠Y-60=90.

Then you add 60 to both sides: 3m∠Y=150

Divide 3 on both sides: 3∠Y=50

What is linear equation in one variable?

The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.

According to the given question

Justin is 2 years older than 1/4 of his brother's age.

Let the age of Justin be x years.

Also, Justin's brother age is 12 years.

Therefore,

The age pf Justin is given by

[tex]x = 2 + \frac{1}{4}(12)[/tex]

solve the above linear equation

⇒ x = 2 + 3

⇒ x = 5 years

Hence, Justin's age is 5 years.

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.
