Now, as you can see - these are ordered pairs. So, in order to find possible solutions - we have to plot this inequality on a graph!

So, let's do this. I am using GeoGebra in order to graph this inequality.

Alright, so... Now I'm going to go through, and look at each ordered pair and see if they are covered by the shaded region!

Answer A: False
Answer B: False
Answer C: True
Answer D: True
Answer E: True
Answer F: True

Hopefully, this helps you! =)

Right, because it has two even sides for the right and angle and the right is a hypotenuse.

Two adjacent sides of a parallelogram have length of 5 cm and 11 cm. Each of the two diagonals divide the parallelogram into two

lora16 [44]

Answer:

20 cm

Step-by-step explanation:

Since the diagonals have to be prime numbers, and they have to be able to be sides of a triangle, the formula would be 6<x<16. The prime numbers in this group are 7, 11, and 13. Since 7 is the smallest prime number in this group and 13 is the largest, 7+13=20.

In a large class of introductory Statistics students, the professor has each person toss a fair coin 1111 times and calculate t

lutik1710 [3]

Answer:

Given:

Sample size, n = 11

P = 0.5

a) The shape of the histogram will be symmetrical. This is because the probability of getting heads and tails is equal.

b) The histogram is centered at

p = 0.5 (because of equal probability of obtaining heads and tails).

c) How much variability would you expect among these proportions?

Here, we are to find the standard deviation.

Let's use the formula:

$\sigma = \sqrt{\frac{pq}{n}}$

Where

p = 0.5(probability of getting heads)

q = 0.5 (probability of getting tails)

Therefore

$\sigma = \sqrt{\frac{0.5 * 0.5}{11}}$

= 0.0227 ≈ 0.023

The standard deviation is 0.023

d) A normal model should not be use here because the success/failure condition is violated, since each student only flips the coin 11 times, it impossible to obtain both at least 10 heads and at least 10 tails. Here, the sample size is too small.
