Answer:

a. Discrete

b.Continuous

Step-by-step explanation:

a. A discrete random variable has a countable number of possible values.

-The probability of each value of a discrete random variable is between 0 and 1, and the sum of all the probabilities is equal to 1.

-The number of free dash throw attempts are countable. Hence, a Discrete Random Variable.

b. -A continuous random variable is a random variable where the data can take infinitely many values.

-A continuous random variable is a random variable is qualitative in nature.

-The amount of rainfall will take different values in different April months. Hence Continuous Random Variable.

Prove the following statement.
gayaneshka [121]

Answer:

You can prove this statement as follows:

Step-by-step explanation:

An odd integer is a number of the form 2k+1 where k\in \mathbb{Z}. Consider the following cases.

Case 1. If k is even we have: (2k+1)^{2}=(2(2s)+1)^{2}=(4s+1)^{2}=16s^2+8s+1=8(2s^2+s)+1.

If we denote by m=2s^2+2 we have that (2k+1)^{2}=8m+1.

Case 2. if k is odd we have: (2k+1)^{2}=(2(2s+1)+1)^{2}=(4s+3)^{2}=16s^2+24s+9=16s^{2}+24s+8+1=8(2s^{2}+3s+1)+1.

If we denote by m=2s^{2}+24s+1 we have that (2k+1)^{2}=8m+1

This result says that the remainder when we divide the square of any odd integer by 8 is 1.

ASAP PLEASE HELP!!!
Mariulka [41]

Z score = (x -mean) /  standard deviation.

For this problem X = 50 cm.

Z-score = (50 - 49.2) / 1.8

Z score = 0.8 / 1.8

Z score = 0.44

Look up 0.44 on a z-score table.

0.44 = 0.6700

0.67 x 100 = 67% will be 50 cm or longer.
