Paid same amount is important.
5 hours each one, and 4 babysitters
5*4 is 20
And if there's 170 dollars she paid in total, then each babysitter earned 170/20 per hour, which is 8.5 dollars per hour
2 x 5
2+2+2+2+2= 10
2 x 5= 10
Answer:
The percentile that corresponds to an IQ score of 115 is 34.13 %
Step-by-step explanation:
Here, we want to find the percentile that corresponds to an IQ score of 115.
To calculate this percentile, we start with making observations. From the question, we are told that the mean score is 100 while the standard deviation is 15.
Now we want to find the percentile for a score if 115. For a score of 115, we can see that the difference between this score and the mean is 15 which is exactly equal to the standard deviation.
What this means is that the score is within +1 SD of the mean.
For a score of within +1 SD of the mean, the percentile is 34.13%
A score at the mean is the 50th percentile, a score which is 1 SD above or below the mean has a percentile value of 34.13%
Please, I will like you to check the attachment to see how percentiles are valued given the number of standard deviations a particular value is from the mean.
Answer:
The slope of the graph is: m = -6
The y-intercept of the graph is: b = 2
And the graph of the equation is shown below.
Step-by-step explanation:
We know that the slope-intercept form is

Where m is the slope and b is the y-intercept
Given the equation

comparing with the slope-intercept form
slope = m = -6
y-intercept = b = 2
Thus,
The slope of the graph is: m = -6
The y-intercept of the graph is: b = 2
And the graph of the equation is shown below.
They are because 2.7 squared + 3.6 squared = 4.5 squared (=20.25)
Pythagoras Theorem is that a squared + b squared = c squared
So the 2 smallest numbers squared will equal the larger one squared if it is a pythagoreom triple
