A student had 10 marks in mathematics. But he remembers only 7 of them:
1,1,2,2,3,4,5. The mode of the marks is 3 and the mean is 2.9. What are the
missing marks? Once you manage to find these marks, create a frequency
table for the students' scores and visualize the results with a bar chart.

Answers

Answer:

The missing marks are 3, 3, and 5.

Step-by-step explanation:

Since the mode is 3, that means it's the number that occurs most often. The numbers 1 and 2 occur twice so there must be at least 3 3's on the list. But since the mean is 2.9, the third mark cannot be a 3 because it will make the mean only 2.7 so the 3rd mark can be either a 4 or a 5. Using 5 will make the mean 2.9. I take it that you know how to make a bar graph for this problem.

8. When nominal GDP is $900 and the price index is 150, real GDP would equal
$60
$135
$600
$1,350
$6,000

Answers

Answer:

$600

Step-by-step explanation:

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

Nominal GDP is GDP calculated using current year prices while Real GDP is GDP calculated using base year prices. Real GDP has been adjusted for inflation.

Price index measures how prices change over a period of time. It is a measure of inflation

Real GDP = (nominal / price index) x 100

($900 / 150) X 100 = $600

Find the probability of rolling a number less
than 3 on a die.


Pls help

Answers

Step-by-step explanation:

When a die is rolled, here it's Total possible outcome is= 6

and sample space is = 2 ( i.e. 1 & 2)

So. Probability of getting less than 3 = 26

=13

That's it

I think the answer is 33% probability of rolling a number less than 3. Or 2/6 probability if you are looking for a fraction.
Probability is always the how many over the total. In a die there are 6 chances. And to get less than 3 is only 2 chances. So the fraction is 2/6. Now if you want to find the percent you would have to divide 2 by 6. That will get you 0.333. If you round and make it into a percent that would be 33%.
