Answer:
b
Step-by-step explanation:
b
Answer:
Formula: a² + 2ab + b² = (a + b)²
The square root of 1/9x² = 1/3x so a = 1/3x and b = 1/5y.
The answer is (1/3x + 1/5y)².
Answer:
t distribution behaves like standard normal distribution as the number of freedom increases.
Step-by-step explanation:
The question is missing. I will give a general information on t distribution.
t-distribution is used instead of normal distribution when the <em>sample size is small (usually smaller than 30) </em>or <em>population standard deviation is unknown</em>.
Degrees of freedom is the number of values in a sample that are free to vary. As the number of degrees of freedom for a t-distribution increases, the distribution looks more like normal distribution and follows the same characteristics.
Answer:
(41/12)g+-23/12
Step-by-step explanation:
3(5g−1)
/4 - (2g+7)/6
(15g-3)/4 - (2g+7)/6---> distributive property
3(15g-3)/12 - 2(2g+7)/12--->make the denominators same
(45g-9)/12 - (4g+14)/12---distributive property
