g Suppose that you randomly selected 20 adults. If 18% of the population smoke, a) Using the Range Rule of Thumb, what is the mi

Gala2k [10]

Answer:

0.16

Step-by-step explanation:

The computation of the minimum no of usual smokers expected to get out of 20 adults is shown below:

Here the standard deviation is

$= \sqrt{npq} \\\\= \sqrt{20\times 0.18 \times (1 - 0.18)}\\\\= \sqrt{20\times 0.18\times 0.82}\\\\= \sqrt{2.952}$

= 1.72

Now the minimum no of smokers is

$= np - 2\times 1.72\\= 20 \times 0.18 - 3.44\\\\= 0.16$

jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x becaus

Pie

Answer:

$x = \frac{d+c}{a - b}$

Step-by-step explanation:

Equation: $ax – c = bx + d$

Jalil says it is not possible to isolate x because x has a different unknown coefficient.

Victoria t. Victoria believes there is a solution

Solving the equation:

$ax-c = bx + d$

$ax - bx= d+c$

$(a - b)x = d+c$

$x = \frac{d+c}{a - b}$

So, this shows x can be isolated .

Victoria was right .

It was not possible to isolate x if the coefficients of x would be same .

But in the given equation the coefficients of x are not same .

So, Victoria is right.
