Answer:

Option B.

Step-by-step explanation:

Continuous probability distribution : A probability distribution is called a continuous probability distribution, if its random variable X is a continuous variable and it can take infinite values (Real values).

Number of boxes cannot be a decimal value. So, it is not a continuous variable. Thus, option A is incorrect.

Temperature of a day is a continuous variable. So, temperature of a day can be represented using a continuous probability distribution. So, option B is correct.

Marks in a test paper cannot represent a continuous variable. Thus, option C is incorrect.

Number of students who uses the internet cannot be a fractional or decimal value. So, it is not a continuous variable. Thus, option D is incorrect.

Therefore, the correct option is B.

Help with #2 it has to do with number 1 that is the polygon you need to find the area of it.

Katena32 [7]

Okay, it's the equation to how find area any other way. A=L×W

This means *picture above*

So then you count over each line meaning 1.
This means L=9 and a 1/2. Since its in between the 2 an 3 on the x-axis.
Now for W or width. It equals 3 since you can count 2 lines and one either ends of the polygon is 1/2 each this creates one when added together.

All you do from there is multiply 9 and 3. This should give you A=area.

Write an equation to find the amount of interest $450,000 earns in 1 year at a simple interest rate of 3.5%.

telo118 [61]

Answer:

The required equation for the amount of Simple Internet = $\frac{450,000 \times 1 \times 3.5}{100}$

Step-by-step explanation:

Here , Principal amount = $450,000

Time = 1 year

Rate of Interest = 3.5%

Now,SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

So, here SI = $\frac{450,000 \times 1 \times 3.5}{100}$

Hence, the required equation for the amount of Simple Internet = $\frac{450,000 \times 1 \times 3.5}{100}$

Total revenue is 3,000 cost of goods 1,500 total selling expence is 500 what is profit

12345 [234]

Cost of goods = 1,500
Selling expense = 500

Total cost in selling = 1500 + 500 = 2000

Profit = Total Revenue - Total cost in selling = 3000 - 2000 = 1000

Profit = 1000

Hope this explains it.

The company makes a profit of 15% on every faucet sold. What is the profit on one shower faucet ?

Rama09 [41]

Answer:

Hi there!

Your answer is:

D: 18.00$

Step-by-step explanation:

First, we plug in all the numbers under the columns "Kitchen Sink", "Bathroom Sink" and "Shower" in our matrix calculator as A. Then, we plug in all the numbers under "Total Selling Price" in our matrix calc as B. Then, we perform the equation A^-1 * B. We will look to the 3rd row for this, since shower is our "z" and the third row represents z

Since profit is determined by .15 * 120, we calculate this. Your answer is 18.

Hope This Helps
