A town council wants to estimate the proportion of residents who are in favor of a proposal to upgrade the computers in the town library. A random sample of 100 dants was selected and 7 of those selected indicated that they were in favor of the proposals appropriate to assume that the sampling distribution of the sample proportion is approximately normal

a. A No, because the sample is not large enough to satisfy the normality conditions
b. No, because the size of the population is not known.
c. Yes, because the sample was selected at random
d. Yes, because sampling distributions of proportions are modeled with a normal model
e. Yes, because the sample is large enough to satisfy the normality conditions

(23*2)-12=x     x=34

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
