Answer:
Option A is the correct answer
Step-by-step explanation:
A. The difference of twice the cube of a number and 11
The answer is = 4 points per minute
Answer:
We use cosine rule also called cosine law which states
c^2=a^2+b^2-2abcosC
given
a=8cm, b=7cm, c=9cm cos C?
9^2=8^+7^2-2*8*7 cos C
expand
81=64+49-112 cos C
like terms together
81-113=-112 cos C
-32=-112cos C
multiply both sides by -1
32=112cos C
divide both sides by 112
32/112=cos C
cosC=0.2857
find cos inverse of 0.2857
angle C= 73.40
It should be 5√3
Because 25 x 3 = 75
√25=5 so u bring that out and keep the 3 in because it’s a prime number
The top 15% (85th percentile) is the cutoff value
such that
where
is the corresponding cutoff for the standardized normal distribution. We have
, and so
