Answer: a=2 b= 11/6 or 1 5/6
Step-by-step explanation:
Step-by-step explanation:
could not find the formula ?
the volume of a cylinder is ground area × height.
and the ground area is a circle.
so, all in all we get
pi×r²×h
with r being the radius (half of the diameter), and h being the height.
in our case we get
pi×(140/2)²×10 = pi×70²×10 = 49000×pi =
= 153,938.04... cm³
Answer:
D) Standard deviation is 5.41
Step-by-step explanation:
We are given
count N = 9
Sum ∑xi = 113
Mean = ∑xi /N = 12.55
Standard deviation = where i = 1 to 9
upon substituting the values we get
Standard deviation = = 5.41
0.1875
Step-by-step explanation:
Step 1:
Let the given expression in word form be expressed as
Step 2:
Let us we simplify it using BODMAS rule.
(-12)/ ( 3(-8-8-6) + 2)
(-12) / (3(-22)+2)
0.1875
