Answer:
f(10)=sqrt(14)
Step-by-step explanation:
f(10) = sqrt(2x-6)
f(10)= sqrt(20-6)
f(10)=sqrt(14) - simplest form, no way to factor it.
Answer:
0.2839 = 28.93%
Step-by-step explanation:
In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z
Le x be tons of coal in a car
Z = (x – mean)/standard deviation
Z = (x – μ)/ σ
P (x<68.5) = P(z < (68.5-69)/0.9)
P (x<68.5) = P(z < -0.5555)
Then we use the z table to find the area under the curve.
P (x<68.5) = 0.2893
6-z
Z-6 would be wrong because the question said start with 6
I think it’s 60 if that’s what your asking
Answer: There are 17 times 13 in 223. The answer you divide 223 by 13 which would get you 17.153846153846.
