Answer:
<em>hello your question lacks some information attached below is the complete question</em>
answer : NO
Step-by-step explanation:
Determine the probability of not selecting an obese subject in 3 trials
= P ( not obese in 3 randomly selected ) = ( 1 - 0.111 )^3
= 0.703
The probability > 0.05
hence it is insignificant therefore the answer is NO
Answer:
2414.42 cm^2
Step-by-step explanation:
volume = base x height
and we know that a cube will always have the same length for any side so volume is basically length^3
volume = length^3
8073 = x^3
x = ![\sqrt[3]{8073}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8073%7D)
use a calculator and you get that x = 20.06 cm
Surface area(SA) = 6a^2 (a is area)
a = x^2
so SA = 6(20.06)^2 = 2414.4216 ≈ 2414.42 cm^2
If he multiplied the first equation by 5, that would give us:
10x + 45y = 205
Now we need to get -45y to eliminate the y-terms, So we divide -45 / 5 and we get -9. So we multiply the 2nd equation by -9.
(I'm assuming the first equation is actually 2x + 9y = 41, and not 2x + 9 = 41)
