The data in the tables below were collected from first year students at a community college. The variable is "number of credit c

Oliga [24]

Solution :

It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :

1. $P(x) \geq 0$

2. $\sum_z P(x) = 1$

Now consider,

$\sum_z P(x) = 1$

⇒ $P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$

⇒ $0.61+T+0.14+0.01+0.01+0.03=1$

⇒ $0.8+T=1$

⇒ $T=1-0.8$

= 0.2

Therefore, the value of T is 0.2

Thus, option (c) is correct.

The number a exceeds the number b by 50 percent. By what percent is the number b smaller than the number a?

Julli [10]

50%, because to exceed is to be larger than, so if A is larger than B by 50%, then that means that B is 50% smaller than A.

Answer:

Step 5

Step-by-step explanation:

The mistake is in step 5.

The previous step was

$step \: 4 : 2 + 10 \div 2$

The order operations, PEDMAS, must be applied:

We have Addition and Division here,

Using PEDMAS, we must divide first to get:

$step \: 5 : 2 + 5$

We can now add to get:

$step \: 6: 7$

Therefore the mistake occurred at step 5
