Angles: Arcs & Angles Need Help Thank You!!

Answers

Answer 1

Answer:

See answers below

Step-by-step explanation:

1) The typr of triangle in a semicircle is a right angle. Hence the measure of  m<ABC  is 90degrees

2) m<DEF = 1/2(144)

m<DEF = 144/2

m<DEF = 72degrees

3) From the trinagle

4x+3 + x+7 +90 ==180

5x + 100 = 180

5x = 180-100

5x = 80

x = 80/5

x = 16

<QRD =  x+7

m<QRD = 16 + 7

m<QRD = 23degrees

4)  Angle in the same segment are equal

5x-37= 3x+1

5x - 3x = 1+37

2x = 38

x = 38/2

x =19

arc NM = 2m<P

arc NM = 2(3x+1)

arc NM = 2(3(19)+1)

arc NM = 2(58)

arcNM = 116degrees

a data set has a mean 25 and standard deviation 5 find the z score of 39

Answers

The answer to your question is 14/5

Answer:

[tex]\boxed {\boxed {\sf z=2.8}}[/tex]

Step-by-step explanation:

The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:

[tex]z= \frac{x- \bar x}{s}[/tex]

where x is the value, x-bar is the mean, and s is the standard deviation.

We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.

x= 39 x-bar= 25 s=5

Substitute the values into the formula.

[tex]z= \frac{ 39-25}{5}[/tex]

Solve the numerator.

[tex]z= \frac{ 14}{5}[/tex]

[tex]z=2.8[/tex]

The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.
