Domain of the function

Umnica [9.8K]

F(x) = ln (6-x); find the domain.

The domain of the "ln" function is (0, infinity), or "x is greater than zero."

Thus, the domain of the given function is "(6-x) is greater than zero."

Solve this: 6-x > 0. Add x to both sides. Then 6 > x, or x < 6 (answer)

Rama09 [41]

Answer: 1.300228

Step-by-step explanation:

The t-score we use for the confidence interval is two-tailed , i.e. the t-score should be used to find a ( $1-\alpha$ ) is given by :-

$t_{n-1, \alpha/2}$ , where n is the sample size.

Given : Level of confidence: $1-\alpha: 0.80$

Significance level : $\alpha: 1-0.80=0.20$

Sample size : n= 47

Then, degree of freedom : $n-1=46$

Now by using standard normal t-distribution table,

$t_{n-1, \alpha/2}=t_{46, 0.10}=1.300228$

Hence, the t-score should be used to find a 80% confidence interval estimate for the population mean = 1.300228

3x + 4y= 16 solve for y

Pepsi [2]

3x + 4y = 16
<u>- 3x -3x</u>
4y = -3x + 16 (divide each side by 4)
$\frac{4y}{4} = \frac{-3x+16}{4}$
y = -3/4x + 16/4

The answer is $y =- \frac{3}{4}x +4$
