Answer:
The percentage of people that could be expected to score the same as Matthew or higher on this scale is:
= 93.3%.
Step-by-step explanation:
a) Data and Calculations:
Mean score on the scale, μ = 50
Distribution's standard deviation, σ = 10
Matthew scores, x = 65
Calculating the Z-score:
Z-score = (x – μ) / σ
= (65-50)/10
= 1.5
The probability based on a Z-score of 1.5 is 0.93319
Therefore, the percentage of people that could be expected to score the same as Matthew or higher on this scale is 93.3%.
Answer:
C. -1 9/10, -1/2, 0.4, 3/5
Step-by-step explanation:
Using a number line, we can see that negative numbers are to the left of '0' and positive numbers are to the right of '0'. To compare numbers for increasing order, we would start with the lowest number to the farthest left on the number line to the greatest number to the farthest right. Placing the following numbers on the number line, the furthest to the left is -1 9/10, then -1/2, followed by 0.4 and then the greatest, 3/5. You can also compare by converting them all into decimals:
-1 9/10 = -1.9
-1/2 = -0.5
0.4 = 0.4
3/5 = 0.6
Answer:
-18 - 24y.
Step-by-step explanation:
6(-3-4y)
We use the distributive law to give:
6 * -3 + 6* -4y
= -18 - 24y.
