4 1/3 divided 5 1/6<br> Please help me!
Effectus [21]

Answer:

6/31

Step-by-step explanation:

4 1/3 ➡ 13/3

5 1/6 ➡ 31/6

to divide two rational expression you should turn the second number upside-down(finding its reciprocal) then multiply them :

13/3 × 6/31 = 26/31

The interior angles formed by the sides of a pentagon have measures that sum to 540°.
alexgriva [62]

Answer:

The Solution to the Sum

Your solution after multiplying the 3 with the 180 degrees is 540 degrees. This is true for any pentagon you have. Regular pentagons where all the sides and angles are the same will have a sum of interior angles of 540 degrees.

Write an equation of the line that passes through (1,2) and is perpendicular to the line y= 1/3x+4
zvonat [6]

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be perpendicular, their slopes have to be the negative reciprocal of each other. (Basically flip the sign +/- and the fraction(switch the numerator and the denominator))

For example:

Slope = 2 or \frac{2}{1}

Perpendicular line's slope = -\frac{1}{2}   (flip the sign from + to -, and flip the fraction)

Slope = -\frac{3}{4}

Perpendicular line's slope = \frac{4}{3}  (flip the sign from - to +, and flip the fraction)

y = 1/3x + 4        The slope is 1/3, so the perpendicular line's slope is -\frac{3}{1} or -3.

Now that you know the slope, substitute/plug it into the equation:

y = mx + b

y = -3x + b       To find b, plug in the point (1, 2) into the equation, then isolate/get the variable "b" by itself

2= -3(1) + b     Add 3 on both sides to get "b" by itself

2 + 3 = -3 + 3 + b

5 = b

y = -3x + 5

Answer:

The z-score for the trainee is of 2.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The mean of the test scores is 72 with a standard deviation of 5.

This means that \mu = 72, \sigma = 5

Find the z-score for a trainee, given a score of 82.

This is Z when X = 82. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{82 - 72}{5}

Z = 2

The z-score for the trainee is of 2.

Please help me answer this and learn how to find the equation for line of best fit
const2013 [10]

Answer:

y=-12/5x+62

Step-by-step explanation:

to solve this i turned two point form, 5,50 and 17 1/2,20, into slope intercept form by using the formula y-y1=(y2-y1/x2-x1)(x-x1), which when input with the data becomes y-50=(20-50/17 1/2-5)(x-5) which then becomes y-50=-12/5(x-5), then y-50=-12/5x+12, and finally y=-12/5x+62
