Can three line segments with the given lengths form a right triangle?
musickatia [10]

Answer:

Yes

12, 35, 37

16, 30, 34

20, 21, 29

No

18, 24, 42

Step-by-step explanation:

Required

Determine which length form a right triangle

To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths

So:

(1) 12, 35, 37 --- Yes

37^2 = 35^2 + 12^2

1369 = 1225 + 144

1369 = 1369

(2) 16, 30, 34 --- Yes

34^2 = 16^2 + 30^2

1156 = 256 + 900

1156 = 1156

(3) 18, 24, 42 --- No

42^2 =18^2 + 24^2

1764 =324 + 576

1764 =900

1764 \ne 900

(4) 20, 21, 29 -- Yes

29^2 = 20^2 + 21^2

841= 400 + 441

841= 841

The equation y+6=1/3(x-9) is written in point-slope form. What is the equation written in slope-intercept form?
Margaret [11]

y+6=1/3(x-9)

Moved all terms from left to right that doesn't contain y

Y=-6 +1/3x-3

Simplify

Y=1/3x-9

Assume that the random variable X is normally​ distributed, with mean muequals45 and standard deviation sigmaequals10. Compute t
saul85 [17]

Answer:

0.1069 = 10.69%

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this question:

\mu = 45, \sigma = 10

Between 57 and 69

This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So

X = 69

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

Z = \frac{69 - 45}{10}

Z = 2.4

Z = 2.4 has a pvalue of 0.9918

X = 57

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

Z = \frac{57 - 45}{10}

Z = 1.2

Z = 1.2 has a pvalue of 0.8849

0.9918 - 0.8849 = 0.1069 = 10.69%
