Answer:
x = 3
Step-by-step explanation:
x = (sq rt 3)( sq rt 3) because the leg opposite the 30 degree angle (sq rt 3) times the set value of sq rt 3 = the leg adjacent to the 30 degree angle.
x = (sq rt 3)(sq rt 3)
x = 3

A basketball coach kept stats for his team in free throw percentage and steals (among others). At the last game, Erin's free throw percentage was 79% and she had 4 steals. The team averaged 87% from the free throw line with a standard deviation of 12 and they averaged 7 steals with a standard deviation of 3. In which category did Erin do better compared with her team
Answers
Answer:
Due to the higher z-score, she did better in the free throw category.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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:
She did better in the category that she had the higher z-score:
Free-throws:
Her free throw percentage was 79%, which means that [tex]X = 79[/tex]
The team averaged 87% from the free throw line with a standard deviation of 12, which means that [tex]\mu = 87, \sigma = 12[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{79 - 87}{12}[/tex]
[tex]Z = -0.67[/tex]
Steals:
She had 4 steals, which means that [tex]X = 4[/tex]
Averaged 7 steals with a standard deviation of 3, which means that [tex]\mu = 7, \sigma = 3[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{4 - 7}{3}[/tex]
[tex]Z = -1[/tex]
Due to the higher z-score, she did better in the free throw category.

WILL MARK BRAINLYIST what are the values of X,Y, and z
Answers
Answer:
x=111, y=36, z=76
Step-by-step explanation:
Therefore x is 111 degrees
To find y, we will use the triangle method. We know that a triangle adds to 180, and so do two adjacent angles on a straight line.
180-66 = 114
180 - 114 - 30 = y
Therefore y is 36 degrees.
Same principles with z.
180- 119 = 61
180 - 61 - 43 = z
Therefore, z is 76 degrees.
Final:
x = 111
y = 36
z = 76
