A teacher gave a unit test to both of her statistics classes. The mean test grade for Class A was 77 points, with a standard deviation of 5 points, whereas the mean test grade for Class B was 80, with a standard deviation of 7 points. Kyle, in Class A, received an 82 on the test, and Caleb, in Class B, received an 87. Whose performance on the unit test was better relative to their class?
Answers
Answer:
i think they would be the same
Step-by-step explanation:
77+5=82 or 77-5=72
so he is within the range of 72-82
80+7=87 80-7=73
so he is also within the range of 73-87
Since both Kyle and Caleb scored 1 standard deviation above their respective class means, we can conclude that their performances were relatively equal.
What is standard deviation?A standard deviation is a measure of how far apart the data is from the mean.
A low standard deviation indicates that data is clustered around the mean, whereas a high standard deviation indicates that data is more spread out.
To determine whose performance was better relative to their class, we need to calculate their z-scores, which tell us how many standard deviations a particular score is from the mean.
For Kyle in Class A:
z-score = (82 - 77) / 5 = 1
This means that Kyle's score is 1 standard deviation above the mean for his class.
For Caleb in Class B:
z-score = (87 - 80) / 7 = 1
This means that Caleb's score is also 1 standard deviation above the mean for his class.
Thus, we can conclude that Kyle and Caleb's performances were comparable because they both scored one standard deviation above their respective class means.

John is performing an experiment in which a solution alternates between a clear color and a bluish-purple color at a regular time interval. He observes that the time interval between color changes is 30 seconds (s). Sally replicates the experiment with the same solution, but at a temperature that is 10 degrees Celsius (°C) higher. What is the most likely time interval between color changes at this higher temperature?
Answers
Answer:
15 seconds
Step-by-step explanation:
The given parameters for the experiment are;
The time it takes the solution to change from a clear color to a bluish-purple color at a given temperature = 30 seconds
The temperature at which Sally replicates the experiment with the same solution = 10°C higher than the temperature the experiment was carried out by John
Given that the process involves a change in color, which is a characteristic of a chemical reaction, and that the rate of a chemical reaction increases as the temperature of the reacting system is increased, we have time it takes for the solution to change color at a temperature increased by 10°C, will be a time lesser than 30 seconds

Answer:
The value of 2 pennies and 3 dimes is 17¢. The value of p pennies and d dimes is (p×1)+(d×5)
Step-by-step explanation:
Use the formula (p×1)+(d×5).
Insert the number of pennies and dimes into the formula: (2×1)+(3×5).
Solve the equation: (2×1)+(3×5)
= 2+(3×5)
= 2+15
= 17
So, there are 17¢ in 2 pennies and 3 dimes.

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the first cyclist bike in 45 minutes?
Answers
Answer:
9 miles
Step-by-step explanation:
If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.
30+15=45
6+3=9
The first cyclist bikes 9 miles in 45 minutes.
Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:
60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X
Therefore, the first cyclist bikes 9 miles in 45 minutes.
