A fast food restaurant executive wishes to know how many fast food meals adults eat each week. They want to construct a 95% confidence interval with an error of no more than 0.07 meals. A consultant has informed them that a previous study found the mean to be 8.1 fast food meals per week and found the standard deviation to be 2.

What is the minimum sample size required to create the specified confidence interval?

Round your answer up to the next integer

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

i got so much points from yo a.
