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

1 month 29 days but if the month have 29 days each then the it will be 2 months
The <u>cost</u> of his meal at a cafe is $36.00 and Cristofer wants to leave a <u>10% tip</u>. So to find what is his <u>total bill</u>, you have to <u>count 10% from</u> $36.00.
Note that
$36.00 -- 100%,
$x -- 10%.
Write aproportion:
Then
Therefore, the total bill consists of $36.00 for the meal and $3.60 tip:
$36.00 + $3.60 = $39.60.
Answer: $39.60
