DAT MathCircle Area - ANS πr²
Area of a triangle - ANS A=1/2bh
Area of a square - ANS A=s²
Volume of a Sphere Formula - ANS V=4/3πr³
Volume of a cylinder - ANS V=πr²h
Combination Formula - ANS nCr = n!/r!(n-r)!
order DOES NOT matter
Permutation Formula - ANS nPr = n!/(n-r)!
order MATTERS
1 inch = ? cm - ANS 2.54 cm
1 mile = ____ feet - ANS 5,280 feet
1 ft = ? in - ANS 12 in
1 yard = ____ feet - ANS 1 yard = 3 feet
1 m = _ yard - ANS 1.1 yard
1 kg = ? Ibs - ANS 2.2 Ibs
1 lb= _ g = _ ounces - ANS 454 g = 16 ounces
vertical elipse formula - ANS y^2 / a^2 + x^2 / b^2 = 1
By definition, the y intercept must have an x-coordinate of - ANS zero
1 centi = _milimeters - ANS 10
, complementary angles - ANS Two angles whose sum is 90 degrees
90- angle
supplementary angles - ANS Two angles whose sum is 180 degrees
Sum of Internal Angles of a Polygon - ANS 180(n-2)
angle = # you got / number of the gon.
SD facts - ANS if the spacing of sd is same then the sd is the same even if one number range
is larger numbers.
when median number repeats= decrease spread of data
repeating the max number increases the spread of data
mean decreases spread of data.
if the data sets are reasonably symmetrical and contain a variety of points around the mean.
Does that mean it has a pretty big sd?
Diagonal of a square - ANS s^2+ s^2 = d^2
Distance Formula - ANS d = √[( x₂ - x₁)² + (y₂ - y₁)²]
midpoint formula - ANS (x₁+x₂)/2, (y₁+y₂)/2
Surface Area of a Cylinder - ANS 2πrh+2πr²
standard dev can not be greater than the - ANS max distance from the mean( the smallest
number )
price/ amount - ANS
Area of a parallelogram - ANS A=bh or l1xl2xsin (theta)
Compound Interest Formula - ANS A=P(1+r/n)^nt
FV = PV(1 + (rate))n
P is the starting population
r is the "interest rate" (written as a decimal the percent) per time period,
