Answer:

c

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

3x - y = 1 → (2)

Adding the 2 equations term by term will eliminate the term in y

4x = 4 ( divide both sides by 4)

x = 1

Substitute x = 1 into either of the 2 equations and evaluate for y

Substituting into (1)

1 + y = 3 ( subtract 1 from both sides )

y = 2

Solution is (1, 2 ) → c

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

Write the word sentence as an inequality. Then solve the inequality.
Agata [3.3K]
The solution is x>18.

The problem tells us that 3 less than a number: x-3
is more than 15. >15
So the inequality is x-3>15. When we isolate x to simply the inequality, we add 3 to both sides, to get x>18.
