natka813 [3]

Answer:

Step-by-step explanation:

To be right triangle has to verify the Pythagorean Theorem

hypothenuse² = (side 1 )² + (side 2)²

Since the hypothenuse is the largest of the sides we consider the largest number the hypothenuse and check the relation.

16, 30, 34

34² = 16²+30²; 1156 = 1156 ✅

16, 30, 34 are measurements of a right triangle

8, 14, 16

16² = 8² +14²; 256 = 260 ❌

8, 14, 16  is not a right triangle

10, 12, 16

16² = 10² +12²; 256 = 244 ❌

10, 12, 16 is not a right triangle

5, 12, 13

13² = 12²+5²; 169 = 169 ✅

5, 12, 13 are measurements of a right triangle

What is log6^e f rewritten using the power property?
marishachu [46]

Given expression : log_6e^f ..

We need to apply power property of logs to rewrite it.

According to log rule of exponents:

log_b a^n = n log_b(a)

If we compare given expression with the rule the exponent part is f, base is 6.

Therefore, we need to bring exponent f in front of log.

Therefore, log_6e^f  = flog_6 e.

<h3>And correct option is second option flog_6 e.</h3>

Calculate the correlation coefficient for the given data below:
Rasek [7]

The correlation coefficient of the data provided is -0.52.

<h3>What is the correlation coefficient?</h3>

Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.

Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.

Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52
