How is the graph of y = –x2 – 1 different from the graph of y = –x2?

KonstantinChe [14]

Every transformation like

$f(x)\mapsto f(x)+k$

translated the graph vertically, k units up if k is positive, k units down if k is negative.

So, in your case, we have that $-x^2-1$ is the same graph as $-x^2$ , except it's shifted 1 unit down.

The results of a survey show that the percent of students in an Algebra II class who want to have their grades scored on a curve

Hoochie [10]

A. The point estimate would be the average of the interval boundaries, which is the average of 48.2 and 56.4. This gives a point estimate of 52.3%.
b. The margin of error is the distance from either interval boundary to the point estimate. 56.4 - 52.3 = 4.1%.
c. Assuming this is solely going to be based on the class' decision, their grades should be scored on a curve. Although the margin of error is high and this seems to not have a significant distance from 50%, there is no "middle ground" in this option. We must either grade on a curve or not, and if we must choose one, we have to use to point estimate that is just slightly above 50%.

After hearing of the national result that 44% of student engage in binge drinking (5 drinks at a sitting for men, 4 for women),

yKpoI14uk [10]

Answer:

Should he be surprised at this result

The found proportion is 1.56 standart deviations away from the expected. we should no be surprised .

Step-by-step explanation:

p=0,44

q=1-0.44=0.56

u=p=0,44

o= $\sqrt{pq/n}$ = $\sqrt{(0.44)(0.56)/244}$ = 0.032

proportion of students in binge drinking 96/244 = 0.39

The found proportion is 1.56 standart deviations away from the expected. we should no be surprised .
