Hi Briana.

All triangles have a total internal measurement of 180 degrees from their angles. Isosceles triangles have two similar side lengths, and one different side length also known as the base. Considering we have the base, we can determine the side lengths by using the following equation:
2x + 24 = 96
Let's get to solving!

2x + 24 = 96; subtract 24 from both sides.
2x = 72; divide both sides by 2 to solve for the measurement of each side length.
x = 36;

Your answer is B.) 36

I hope this helps!

Park Crest Middle School has a population of about 400 Eighth Graders.

Kobotan [32]

Answer:

$10^3$ times

Step-by-step explanation:

Given

Let

$P \to$ Park Crest Middle School

$T \to$ Total

So, we have:

$P = 400$

$T = 406240$

Required

Determine the number of times T is greater than P

This is calculated by dividing T by P.

i.e.

$n = \frac{T}{P}$

So, we have:

$n = \frac{406240}{400}$

$n = 1015.6$

Approximate

$n \approx 1000$

As a power of 10, we have:

$n = 10^3$

The lifetime of a certain type of battery is normally distributed with mean value 15 hours and standard deviation 1 hour. There

KIM [24]

Answer:

If the lifetime of batteries in the packet is 40.83 hours or more then, it exceeds for 5% of all packages.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 15

Standard Deviation, σ = 1

Sample size = 4

Total lifetime of 4 batteries = 40 hours

We are given that the distribution of lifetime is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling:

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{1}{\sqrt4} = 0.5$

We have to find the value of x such that the probability is 0.05

P(X > x) = 0.05

$P( X > x) = P( z > \displaystyle\frac{x - 40}{0.5})=0.05$

$= 1 -P( z \leq \displaystyle\frac{x - 40}{0.5})=0.05$

$=P( z \leq \displaystyle\frac{x - 40}{0.5})=0.95$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 40}{0.5} = 1.64\\x = 40.825 \approx 40.83$

Hence, if the lifetime of batteries in the packet is 40.83 hours or more then, it exceeds for 5% of all packages.
