In a particular year, the mean score on the ACT test was 22.5 and the standard deviation was 5.3. The mean score on the SAT math
RideAnS [48]

Question is incomplete ; The questions solved were picked from similar questions but different parameters. However, the solution pattern are exactly the same.

Answer:

- 0.0943

- 0.386

30.185

Step-by-step explanation:

Given :

ACT:

Mean score, m = 22.5

Standard deviation, σ = 5.3

SAT :

Mean score, m = 526

Standard deviation, σ = 101

1.)

Zscore for ACT score of 22:

Since the distribution is normal ; we use the relation ;

Zscore = (score - mean) / standard deviation

Score = 22

Zscore = (22 - 22.5) / 5.3 = - 0.0943

B.)

Zscore for SAT of 487

Zscore = (score - mean) / standard deviation

Score = 487

Zscore = (487 - 526) / 101 = - 0.386

C.)

ACT score, for ACT Zscore of 1.45

Zscore = (score - mean) / standard deviation

ZScore = 1.45

1.45 = (score - 22.5) / 5.3

1.45 * 5.3 = (score - 22.5)

7.685 = score - 22.5

Score = 7.685 + 22.5

Score = 30.185

mayflies can live at the bottom of lakes for 2 to 3 years before they become winged adults.Mayflies are between 4/10 inches and
Airida [17]

To simplify any fraction, look for a common factor in the top number
and the bottom number.  If you find one, divide the top and bottom
both by their common factor.  Eventually, you reach the point where
their only common factor is ' 1 ' ... that's when it's in simplest form.

4  and  10  both have  2  as a factor. 

When you divide top and bottom both by  2,  you have  2/5 .
This is the simplest form of  4/10 .

None of this has anything to do with mayflies.  You can use the same
process to simplify fractions in ANY situation where fractions arise.
