Answer:
Step-by-step explanation:
value of 4, and you want to square it or exponent 2
so 4^2 = 4x4
=16
What is ^-2
It does the same operation however because to is negative it really means putting 4 in the denominator so 2 becomes positive. Inverse of the exponent 2
1/4^2 is the same as 4^-2
which will both give 1/16
Required area of shaded portion
= Area of square ABCD - 4 × area of one quadrant
The LCM of 6 and 14 would be 42.
Answer:
0.0016
Step-by-step explanation:
let p = growth probability = 60/100 = 0.6
q = probability of not growing = 1-0.6 = 0.4
Bernoulli equation is used to finish the probability
if exactly one grows, then 9 does not grow
That would be;
P(x = 1) = 10C1 p^1 q^9
= 10 * 0.6^1 * 0.4^9 = 0.001572864 = 0.0016 to 4 d.p
Answer:
350
Step-by-step explanation:
