Step-by-step explanation:
The question says the diameters of 50 pillars were measured. However, only the measurements of 20 pillars were provided.
So, I will work with 20
Given
Solving (a): Frequency distribution table
Using the given intervals:
The table is as follows:
The class mark is the average of the class interval
For instance: The class mark of 61 - 70 is:
<em>This is applied to other intervals</em>
Solving (b): The histogram
<em>See attachment for histogram</em>
The frequency is plotted on the y-axis while the class interval, on the x-axis.
Answer:
-12 47/60
Step-by-step explanation:
-(1 1/5) + (-8 3/4 -2 5/6) = -(1 + 8 + 2 + 1/5 + 3/4 + 5/6)
= -(11 + 12/60 +45/60 +50/60) . . . 60 is the LCD of 1/5, 3/4, 5/6
= -(11 + 107/60) . . . . . . . . . . . . . . . . add the fractions
= -(12 47/60) = -12 47/60 . . . . . . . write as a mixed number
___
Your graphing calculator may be able to do this for you. Many handle mixed numbers with ease.
Answer:
a=3
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2+4^2 = 5^2
a^2 +16 = 25
a^2 =25-16
a^2 = 9
Taking the square root of each side
sqrt(a^2) = sqrt(9)
a =3
