Answer:
False
Step-by-step explanation:
Given that a distribution of numbers has the following five-number summary: 13.7, 24.5, 38.9, 50.0, 73.2
These five numbers are known as minimum, I quartile, Median, III quartile and max respectively.
This gives an idea about the scatter of data on either side of median, the interquartile range, and also help to find outliers if any.
But std deviation is the square root of variance. Variance is the average of sum of squares of deviations from the mean.
Hence without knowing mean and each entry just with five number summary we may not be able to find out the standard deviation.
Answer:
1,800
Step-by-step explanation:
Why is because 6 is over for and u estimate to the nearest hundredth and then again the six is still there so u estimate the with the 100 place with give u a 800 so its 1,800
First you get "y" by itself. To do so you divide 2 on both sides.
y = 3/2x + 5
To write an equation of a line that is PARALLEL to this equation, the slopes have to be the SAME. So the slope is 3/2.
You then use the equation:
y = mx + b
SInce you know "m" you plug it in.
y = 3/2x + b
Now you need to find b. To do so you plug in the point (2, -5) into this equation.
-5 = 3/2(2) + b
-5 = 3 + b
-8 = b
Finally you plug in b and you get your new equation.
y = 3/2x - 8
Answer:
d=6h
Step-by-step explanation:
Speed of the raft= 6 miles per hour
Total distance (d) of the raft= rate × number of hours
d=r*h
Independent variable is the number of hours(h)
Dependent variable is the distance (d)
Equation for the situation
d=r*h
d=distance
r=rate
h=number of hours
From the question,
r=6 miles per hour
Therefore,
The equation is
d=r*h
d=6*h
d=6h
