The slope of the line below is -3. Which of the following is the point-slope
Anna [14]

Given:

The slope of the line is -3.

The line passes through the point (2,-2).

To find:

The point-slope form of the line.

Solution:

Point slope form: If a line passes through the point (x_1,y_1) with slope m, then the point-slope form of the line is:

y-y_1=m(x-x_1)

The slope of the line is -3 and it passes through the point (2,-2). So, the point-slope form of the line is:

y-(-2)=-3(x-2)

y+2=-3(x-2)

Therefore, the required point slope form of the given line is y+2=-3(x-2).

A supervisor has determined that the average salary of the employees in his department is $40,000 with a standard deviation of $
mihalych1998 [28]

The z-score for 36,000 is (36,000 - 40,000) / (15,000 / √25) = -1.333

The z-score for 42,000 is (42,000 - 40,000) / (15,000 / √25) = 0.6667

P(36,000 < x < 42,000) = P(-1.3333 < z < 0.6667)

P(z < 0.6667) - P(z < -1.3333)

0.7475 - 0.0913

0.6562

Weather Station stayed The chance of it raining is 3/5. What percent would that be?
murzikaleks [220]
Answer:

60% chance of rain

Explanation;

A way you can get the percentage would be putting the fraction in your calculator. For example here it is 3/5, when the denominator is 5 you can say 20% for each whole number.

1/5 = 20% chance
2/5= 40% chance
3/5=60% chance
4/5= 80% chance
5/5= 100% chance
