Answer:

x = ± i $\sqrt{2}$

Step-by-step explanation:

Given

3x² + 6 = 0 ( subtract 6 from both sides )

3x² = - 6 ( divide both sides by 3 )

x² = - 2 ( take the square root of both sides )

x = ± $\sqrt{-2}$

= ± $\sqrt{2(-1)}$

= ± ( $\sqrt{2}$ × $\sqrt{-1}$ ) → $\sqrt{-1}$ = i

= ± i $\sqrt{2}$

If two samples are selected from the same population, under what circumstances will the two samples have exactly the same t stat

WARRIOR [948]

If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean

The t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error.

Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers

Hence, If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean

Country A has a growth rate of 3.4% per year. The population is currently 4,118,000, and the land area of Country A is 29,000

Eduardwww [97]

Answer:

time period is 260.57 years

Step-by-step explanation:

given data

growth rate = 3.4 % = 0.034

population = 4118000

area P = 29000000000 square yard

to find out

time period that one person for every square yard of land need

solution

we will apply here population growth formula that is

total population P = initial population × $e^{rt}$ ..............1

here r is rate of growth and t is time period and

we consider here initial population is current population

so put value in equation 1 to get t

29000000000 = 4118000 × $e^{0.034t}$

take ln both side

ln 7042.25 = ln $e^{0.034t}$

8.8596 = 0.034 t

t = 260.57

so time period is 260.57 years
