Answer:

-7

Step-by-step explanation:

You first multiply both sides by 10 to get rid of the decimal points, we don't want them.

25x + 100 = 10x - 5

Then, you subtract 100 from both sides:

25x = 10x - 105

Then, you subtract 10x from both sides:

15x = -105

Lastly, you divide by 15 on both sides:

x = -7

So, your answer is -7 :)

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.

What is the area of this figure?

Kipish [7]

Answer:

Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

Step-by-step explanation: hope this helps
