Answer:

75\sqrt{2}(\sqrt{3}-1)

Step-by-step explanation:

In every right triangle, a leg is given by the multiplication of the sine of its opposite angle and the hypothenuse.

In this case, the opposite angle of x is 15°, and the hypothenuse is 300. So, we have

x = 300\sin(15) = 75\sqrt{2}(\sqrt{3}-1)

Help out please thank you

Answer:

x = 26

Step-by-step explanation:

The three angles form a straight line, so they will sum to 180

4x - 8  + 34  + 76- x = 180

Combine like terms

3x+ 102 = 180

Subtract 102 from each side

3x+102-102 = 180-102

3x= 78

Divide each side by 3

3x/3 = 78/3

x = 26

Suppose that g(x) = f(x) + 6. Which statement best compares the graph of
Alenkasestr [34]

Answer:

The graph of the function  is shifted 6 units above that of the graph of f.

Step-by-step explanation:

Assuming that f and g are functions that map real numbers to real numbers, the graph of f is the set

{f(x) : x in R }

and the graph of g is the set

{g(x) : x in R}

where R is the set of real numbers. Since g(x) = f(x), the graph of g is then

{f(x) + 6 : x in R}.

Comment on the role that the number of observations plays in resistance.
weqwewe [10]

Answer:As the sample size​ increases, the impact of the misrecorded data on the mean decreases.

Step-by-step explanation:

The size of an experiment is very important in a research. Large experimental size with many sample unit helps to minimize error this is because the error is shared among all the samples but when an experimental unit is small the error is usually high.

As sample sizes increases the number of misrecorded data on the mean decreases this is because error is usually spread across all samples in a large sample size and the mean is the average performance of the samples.
