Answer:

e= - 2

Step-by-step explanation:

9e-7=7e-11

add 7 to each side of the equation ( -11 + 7 )

9e=7e-4

subtract 7e from both sides of the equation (9e-7e)

2e=-4

divide 2 to each side of the equation

e= - 2

1. The total area within any continuous probability distribution is equal to 1.00.
olchik [2.2K]

Answer:

1. True

2. False.

3. True.

Step-by-step explanation:

1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).

<em>Hence, for continuous probability distribution: probability = area</em>.

2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.

<em>Hence, it cannot be computed. </em>

3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.

<em>Hence, it can be computed. </em>

A bed is 2400 a discount of 25% was given on the
Brrunno [24]

Answer:

800

Step-by-step explanation:

Given: The selling price of bed is 2400.

          Discount offered is 25%

Lets assume the cost of bed be "x"

Discount offered on the cost price of bed= \frac{25}{100} \times x= 0.25x

∴ Discount offered on the cost price of bed= 0.25x

We know the selling price of bed after discount provided.

Finding the cost price of the bed.

⇒ x-0.25x= 2400

⇒ 0.75x= 2400

cross multiplying both side.

∴ x= \frac{2400}{0.75} = 3200

∴ Cost price of the bed is 3200.

We know selling price of the bed is 2400.

Now, finding the saving.

Saving on the price of bed= Cost price- selling price

Saving= 3200-2400= 800

Hence, saving on the purchase of the bed is 800.

The vertices of a triangle are A(0, 0), B(3, 8), and C(9, 0). What is the area of this triangle?
Harlamova29_29 [7]
Answer: 36 units squared.


Explanation:
Area of a traingle is given by,

| 0.5{x1(y2-y3) + x2(y3-y1) + x3(y1-y2)} |

Accepting the values of the coordinates in x's and y's,

x1 =0, y1=0

x2=3, y2=8

x3 =9, y3=0

= | 0.5 × (-72)|
= 36 unit squared.
