Answer:

x = -3

Step-by-step explanation:

First, we compute -5(x + 7). -5(x + 7) = -5x - 35. Plugging this into the equation, we have -5x - 35 = -14 + 2x Next, we combine like terms by moving all terms with the variable x to the left side. We have -5x - 2x = -14 + 35. We simplify the equation into -7x = 21. Divide 21 by -7, and we get x = -3.

Answer: x=-3

Step-by-step explanation:

Ok let's start by using the distributive property

$(-5)(x)+(-5)(7)=-14+2x\\-5x-35=-14+2x$

Now subtract 2x from both sides

$-5x-35-2x=2x-14-2x\\-7x-35=-14$

Next add 35 to both sides

$-7x-35+35=-14+35\\-7x=21$

Finally divide both sides by -7

$\frac{-7x}{-7} =\frac{21}{-7} \\x=-3$

Answer:

Because we don't know the exact shape of the population distribution since they are not Normally distributed and they are also not very non-Normal

Step-by-step explanation:

We are given;

Population standard deviation;μ = 200

Population standard deviation; σ = 35

Sample size; n = 30

We are told that the weights are not Normally distributed and they are also not very non-Normal. Therefore it means we don't know the exact shape of the population distribution and as such we can't calculate the probability that a randomly selected passenger weighs more than 200 pounds.
