Complete question :
Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is
Answer:
1.26
Step-by-step explanation:
Given that:
For ACT:
Mean score, m = 19.3
Standard deviation, s = 5.3
Zscore for ACT score of 26;
Using the Zscore formula :
(x - mean) / standard deviation
x = 26
Zscore :
(26 - 19.3) / 5.3
= 6.7 / 5.3
= 1.2641509
= 1.26
Answer:
The value of y = 62°
and x = 50°
Step-by-step explanation:
=> 57° + y + 61° = 180°
=> 118° + y = 180°
=> y = 180° - 118
=> y = 62°
Now ,
x° + y° + 67° = 180° { sum of angles of a triangle is 180° }
=> x° + 62° + 68° = 180°
=> x + 130° = 180°
=> x = 180° - 130°
=> x = 50°
Answer is C) 51
Angle y is 62 degrees because it forms a straight line with the angles next to it (57 and 61) so angle y must be 62.
There are 180 degrees in a triangle so 180-62-67 = 51
