What is the equation of the line through (2, –1) and (0, 5)?

Answers

Answer 1

Answer:

B

Step-by-step explanation:

To find the equation, we can use the point-slope form:

Where m is the slope and (x₁, y₁) is a point.

First, we will need to find the slope. Since we have two points, we can use the slope formula:

Let (2, -1) be (x₁, y₁) and let (0, 5) be (x₂, y₂). Substitute appropriately and evaluate:

Therefore, the slope m is -3.

Now, we can use the point-slope form. We also need a point. Let’s use (2, -1) for consistency. So, we will substitute -3 for m and (2, -1) for (x₁, y₁). This yields:

We will now convert this to slope-intercept form. Simplify the left and distribute the right:

Subtract 1 from both sides. Therefore, our equation is:

Thus, our answer is B.

Answer 2

Answer:

(y-y1)=m(x-x1)

y+1=5+1/0-2(x-2)

y+1=6/-2(x-2)

-2y-2=6x-12

6x+2y+14=0

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.

Answer:

Step-by-step explanation:

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

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.
