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 answer is C and please give me brainliet And a like!
Answer: it is c
Step-by-step explanation:
It has two of the same domain
It would be 9/25. First you find the common denominator which is 25 so then you convert 1/5 to 5/25 so now you have 4/25+5/25 which you would get 9/25 and since 9 can only be divided be 3 and 25 can't your answer would be 9/25.
(y-y1)=m(x-x1)
y-(-2)=4(x-3)
y+2=4x-12
y=4x-14
