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:
{-6}
Step-by-step explanation:
Step 1 Raise both sides of the equation to the index of the radical in the case 2



Step 2 Factor
(x + 6)(x + 6) = 0
x + 6 = 0
x = - 6
Step 3 Check -6

The dimension of the rectangular prism are,

Hence, the volume of the prism,



Now, the volume of a cube = side³,
If side =
ft,
Then the volume of each cube,

Hence, the number of cubes that can be packet in the prism





Answer:
a = 18/b²
Step-by-step explanation:
Step 1: Write equation
1/3ab² = 6
Step 2: Solve for <em>a</em>
- Multiply both sides by 3: ab² = 18
- Divide both sides by b²: a = 18/b²
