Hey i think the only mistake i caught was when you put 3 points under the line mark instead of only needing 2.
Possibly another mistake at 3a, Only 2 points (but i could be wrong)




Divide both sides by -2. We know that since 2 is negative, it'll be < (less than) 0. So, the direction of inequality will change.

Divide 26 by -2..we'll get the answer as -13.

Now, subtract 3 from both the sides.

Subtracting -13 by 3..we'll get the answer as -16.

Divide both sides by 2. We know that since 2 is positive, the direction of inequality will remain the same.

Divide -16 by 2..we'll get the answer as -8.

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
Answer:
any, equal
Step-by-step explanation:
A Simple Random Sample reflects that any individual in the population has an equal chance of being selected.
Descending order...largest to smallest
the largest one is the one with the biggest exponent
so the first term is : 7z^4
