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:
Step-by-step explanation:
Let us first find the hypotenuses of the right triangle.
![c=\sqrt{12^2+9^2} =\sqrt{225} = 15](https://tex.z-dn.net/?f=c%3D%5Csqrt%7B12%5E2%2B9%5E2%7D%20%3D%5Csqrt%7B225%7D%20%3D%2015)
![sin(theta) = 12/15 = 4/5\\cos(theta) = 9/15 = 3/5\\tan(theta) = 12/9 = 4/3\\csc(theta) = sin(theta)^{-1} = 5/4\\sec(theta) = cos(theta)^{-1} = 5/3\\cot(theta) = tan(theta)^{-1} = 3/4](https://tex.z-dn.net/?f=sin%28theta%29%20%3D%2012%2F15%20%3D%204%2F5%5C%5Ccos%28theta%29%20%3D%209%2F15%20%3D%203%2F5%5C%5Ctan%28theta%29%20%3D%2012%2F9%20%3D%204%2F3%5C%5Ccsc%28theta%29%20%3D%20sin%28theta%29%5E%7B-1%7D%20%20%3D%205%2F4%5C%5Csec%28theta%29%20%3D%20cos%28theta%29%5E%7B-1%7D%20%3D%205%2F3%5C%5Ccot%28theta%29%20%3D%20tan%28theta%29%5E%7B-1%7D%20%3D%203%2F4)
Answer:
-8 < x, the answer is B
Step-by-step explanation:
Since its starting from -8 and your going to the greater side of the numberline teh variable will be greater than -8, whenever the circle is filled it just means greater than or equal to depending on which side its going. If its filled in, it means that its greater than or equal to or less than or equal to depending on which side its going towards.
Reminder:
<--------------- Negative side/Lower -----------------------> Positive side/Greater
