Answer: the answer is B

Step-by-step explanation: I worked the equations out by using 2 points form the graph. First i plugged in point (2, 100), x=2 and y=100

100= 50 times 2 which is true

The second point i used (5, 250) and once i plugged it in it was true

Conclusion: B is the correct answer, just put coordinates that are on the points into the equation.

A triangle has side lengths of 34 in., 20 in., and 47 in. Classify it as acute, obtuse, or right.

Anestetic [448]

34^2 + 20^2 = 1156 + 400 = 1556

47^2 = 2209

because the squares of the 2 smaller sides is less than the square of the longer side the triangle is Obtuse

A college statistics class at a nearby university has 1,000 students enrolled in it. On a recent exam, the mean score was 75% wi

IceJOKER [234]

Answer:

38.11%

Step-by-step explanation:

Given that:

Mean (μ) = 75, standard deviation (σ) = 5

Z score is a measure in statistics to determine the variation of a raw score from the mean. It is given by the equation:

$z=\frac{x-\mu}{\sigma}$

To calculate the percentage of students scored between a 73 and 78 (C grade), we need to find the z score for 73 and then for 78.

For x = 73, the z score is:

$z=\frac{x-\mu}{\sigma}=\frac{73-75}{5} =-0.4$

For x = 78, the z score is:

$z=\frac{x-\mu}{\sigma}=\frac{78-75}{5} =0.6$

From the probability distribution table:

P(73 < x < 78) = P(-0.4 < z < 0.6) = P(z < 0.6) - P(z < -0.4) = 0.7257 - 0.3446 = 0.3811 = 38.11%
