What is the average number of heartbeats per second?
2 beats per second
1 1/2 beats per second 1 Start Fraction 1 over 2 End Fraction beats per second
3 beats per second
2/3 beat per second
And since I got a 100 on meh test even though I guessed it all ima give da answers
1) 3/2
2) 1 1/2
3) 399
4)D
5) graph C
(Your yw! (-_-) I was bored dats why I gave da answers)
nawh i'll pass
.
Oops wrote it wrong
its 1 1/2
I bet the answer was wrong lmao. never trust bots bro.
The average number of heartbeats per second is 1 1/2 beats per second or 1.5 beats per second.
To calculate the average number of heartbeats per second, we can find the mean (average) of the given values.
The given values are:
2 beats per second
1 1/2 beats per second (1 1/2 can be written as 3/2)
3 beats per second
2/3 beat per second
To find the average, add up the values and divide by the total number of values:
2 + 3/2 + 3 + 2/3 = (4/2) + (3/2) + (6/2) + (2/3) = 15/2 + 2/3
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 6.
(15/2) * (3/3) = 45/6
(2/3) * (2/2) = 4/6
Now, we can add the fractions:
45/6 + 4/6 = 49/6
The average number of heartbeats per second is 49/6, which is approximately 8 1/6 beats per second.
To find the average number of heartbeats per second, we need to calculate the mean value using the provided options.
Option 1: 2 beats per second
Option 2: 1 1/2 beats per second
Option 3: 3 beats per second
Option 4: 2/3 beat per second
To calculate the average, we add up all the options and divide the sum by the number of options.
Calculating the average:
2 + 1 1/2 + 3 + 2/3
First, we need to convert the mixed fraction to an improper fraction:
1 1/2 = 3/2
Now we can add up all the options:
2 + 3/2 + 3 + 2/3 = 4 + 3/2 + 2/3
To simplify the expression, we need to find a common denominator. In this case, we can multiply the fraction 3/2 by 3/3 and the fraction 2/3 by 2/2:
4 + (3/2 * 3/3) + 2/3 * 2/2
= 4 + 9/6 + 4/6
Next, we add the fractions:
4 + 9/6 + 4/6 = (4 + 9 + 4)/6
= 17/6
Now, to find the average, we divide the sum by the number of options:
17/6 ÷ 4
To divide fractions, we multiply by the reciprocal:
17/6 ÷ 4 = 17/6 * 1/4
= 17/24
Therefore, the average number of heartbeats per second is 17/24 beats per second.
Identify the constant of proportionality from the graph
2 2 32 Start Fraction 3 over 2 End Fraction 23 Start Fraction 2 over 3 End Fraction 12
To identify the constant of proportionality from the given data points, we need to examine the relationship between the input and output values in the graph.
The input values (x-axis) are:
2
3/2
2/3
The output values (y-axis) are:
32
23
12
To determine the constant of proportionality, we can compare the ratios of the output values to the corresponding input values.
For the ratio of the first data point:
32 / 2 = 16
For the ratio of the second data point:
23 / (3/2) = (2/3) * 23 = 46/3
For the ratio of the third data point:
12 / (2/3) = (3/2) * 12 = 18
The ratios of the output values to the corresponding input values are:
16, 46/3, 18
These ratios are not equal, indicating that there is no constant of proportionality present in the given data points.
Just pick one
Alright, let's pick the first data point: 2 and 32. The constant of proportionality can be found by dividing the output value (32) by the input value (2).
32 / 2 = 16
Therefore, the constant of proportionality from this data point is 16.
That’s not one of the answers
Apologies for the confusion. Looking at the given options and data points, the constant of proportionality is not explicitly provided. Without additional information or a clear pattern in the data points, it is not possible to determine the constant of proportionality from the given options.
JUST PICK AN ACTUAL OPTION
Apologies for the confusion. Let's pick the third option:
23 Start Fraction 2 over 3 End Fraction
To identify the constant of proportionality, we can compare the ratios of the output values to the corresponding input values.
For the given option, the input value is 2/3 and the output value is 23.
To find the constant of proportionality, we divide the output value by the input value:
23 / (2/3) = 23 * (3/2) = 34.5
Therefore, the constant of proportionality from the given option is approximately 34.5.
THE ANSWERS ARE
2
3/2
2/3
1/2
PICK ONE OF THE ANSWERS
Apologies for the confusion. Let's pick the first option: 2.
For the given option, there is no specific data point provided. However, we can assume that the relationship between the input and output values is a direct proportion.
In a direct proportion, the constant of proportionality will be the same for all data points. Therefore, the constant of proportionality from the given option is 2.
The correct answer is
1
1 ___
2
