The population of a certain country is approximated by the following equation, where x is the number of years since 1980 and P i

marissa [1.9K]

Answer:

In 2010 the population become 206,123,000.

Step-by-step explanation:

Consider the provided equation.

$P=2.748x + 126.199$

Where P represents the population in millions.

We need to determine the year in which the country had population of 206,123,000.

As P is in millions so divide 206,123,000 by one million.

$\frac{206,123,000 }{1,000,000}= 206.123$

Substitute P = 206.123 in above equation.

$206.123=2.748x + 126.199$

$79.924=2.748x$

$x=\frac{79.924}{2.748}$

$x=29.08$

30 year from 1980 the population become 206,123,000.

In 2010 the population become 206,123,000.

vodka [1.7K]

Answer:

150, 200, 300

Step-by-step explanation:

sum the parts of the ratio , 3 + 4 + 6 = 13 parts

divide the total by 13 to find the value of one part of the ratio

650 ÷ 13 = 50 ← value of 1 part of the ratio , then

3 parts = 3 × 50 = 150 ← number of sweets Cia gets

4 parts = 4 × 50 = 200 ← number of sweets Mia gets

6 parts = 6 × 50 = 300 ← number of sweets Tia gets

at the district competition for the 5th grade jump-rope of the year, The following number of jumps without stopping recorded per

Serggg [28]

Well first to find the mean you will have to add up all the numbers together.
5,299 is the total. After you have done that count how many numbers there are. There are 24 numbers. Divide 5,299 by 24 and you get about 220.8. So the mean is 220.8 To find the median number of jumps, write out all the numbers in order from least to greatest. I think you can do this part! The middle number is your answer. If there is no middle number, get the two numbers that are on each side of the middle and divide by 2. Hope I helped!
