On a given line, (on one side) there are a total of 180°

if one line in Problem #3 is bisected by a line, with one half X and the other 120°,

do 180° (the total) minus 120° which=60°

now the hard part, that line that bisected the first line is bisecting a line that is parallel to your second line, the one with <5 and <6

this means that the big angle formed in the first one with 120° is the same angle as in the second line, leaving <5 as 120°
which means <6 is 60°, like in the top part of the problem. You're basically flipping the top line upside down, I hope it helps.

dimaraw [331]

Answer:

the points are (35,30) you may need to search a graph online i used desmos

Step-by-step explanation:

1.     x= Jacksons Cups   y= Lucius Cups2.       x -  y= 5           6x + 3y = 300Substitution:                                                 6 (y+5) + 3y = 300             6y + 30 + 3y = 300                9y =   270                dived both by 9                         y=30        Sub y for other equation            x - 30 = 5         add 30 to both sides           x = 35        Answer:   (35, 30)     Graphing:   x- y = 56x+ 3y = 300solve both for y y = x-5 6x + 3y = 300minus 6x from both sides the points are in y = mx + b y= 1x -5 y= -2x + 100  I will also leave the ss of the graph in the comments if you cannot see it  My labels for the x-axis is Jacksons cups and y Is luscious cups.  Elimination:x - y = 5 6x + 3y = 300 First I manipulated the equations by the following    - 6 (x - y = 5 )   1(6x  + 3y = 300 )      -6x + 6y = -30        6x + 3y  = 300          The 6 x's cancel  and add the y's and real numbers together           9y = 270           dived both by 9                   y= 30        Sub y for other equation                      x - 30 = 6                add 30 to both sides                x= 30  The points are  (35, 30) The solution is (35,30)They represent how many cups they sold.   35 is Jackson cups and 30 is Lucious's cups

The mean for a data set is 60. The Z-score for
Vladimir [108]

Answer:

D. a = 60 and b = 58.8

Step-by-step explanation:

Z-score:

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.

Z-score for data point a is 0.

This means that a is the mean, that is, a = 60.

The z-score for data point b is -0.4.

This means that b must be a value below the mean, that is, a value below 60.

The option that satisfies a = 60 and b < 60 is option D, which is the answer.
