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.
