Since Louis jumped 270 times in 6 hours this means that she jumped:
45 times per hour.
Now we need to find how many times she jumped per minute to do this we have to remember that one hour has 60 minutes then we divide the number of jumps per hour by the 60 minutes, that is:
This means that she jumps 0.75 times per minute. Finally to find out how many times she jumped in foour minutes we multiply the 0.75 by 4:
Therefore, Louis jumped 3 times in four minutes.
Answer:
Kendra ate 1/4 pounds of blueberries.
Step-by-step explanation:
The amount of blueberries Sean had = 1/3 pound
The amount of blueberries Kendra ate = 3/4 of Total available
= 3/4 of (1/3 pounds)
Now, we need to find out the 3/4 amount of 1/3 pound.
3/4 of 1/3 pound =
⇒ 3/4 of the amount 1/3 pound = 1/4 pound
Hence Kendra ate 1/4 pounds of blueberries.
Answer:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
And then the best predicted value of y for x = 41 is:
Step-by-step explanation:
For this case we assume the following dataset given:
x: 38,41,45,48,51,53,57,61,65
y: 116,120,123,131,142,145,148,150,152
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
And then the best predicted value of y for x = 41 is:
