The population in the current year is 31.5 million and the real GDP is $814 million. The previous year's statistics were a popul
andrew11 [14]

Answer:

The change in the standard of living, measured by growth in real GDP per person, is 0.1356%

Step-by-step explanation:

Given,

In the current year,

Population = 31.5 million,

Real GDP = $814 million,

So, the real GDP per person = \frac{814}{31.5} ≈ 25.841

In the previous year,

Population = 31 million,

Real GDP = $800 million,

So, the real GDP per person = \frac{800}{31} ≈  25.806

Hence, change percentage = \frac{\text{Change in GDP per person}}{\text{Previous year GDP per person}}\times 100

=\frac{25.841-25.806}{25.806}\times 100

=\frac{0.035}{25.806}\times 100

=\frac{3.5}{25.806}

≈ 0.1356 %

I have to write the slope and equation of each line pictured in y = mx + b form.
Brut [27]

Answer:

y=7/3x+8

Step-by-step explanation:

You have to start at the 3and rise all the way to the 8 which is 7 and then run which is 3 so the slope mx is 7/3x. To find b which is the y intercept find the point where the line hits the y-axis.

Solve the equation by factoring. z2 − 6z − 27 = 0
Kisachek [45]
The answer is x= 9 and -3

You must fine 2 number that multiply to equal -27 and add to equal -6

(x-9) (x+3)
Then equal the parts of the binomial to zero

x - 9 = 0
x + 3 = 0

You must get x by its self.
When you do so, you'll have the answer as -3 and 9
