1702 8-1 Quadratic Graphs and Their Properties
How are the graphs of y = and y = - 4x2 +1 similar? How are they different?
o A. They have the same vertex, but they open in opposite directions.
o
B. They both open in the same direction, but the second graph is wider than the first graph,
o
C. They are both parabolas, but the second graph opens horizontally instead of vertically.
O
D. They have the same shape and axis of symmetry, but the second graph is shifted up 1 unit.

The ratio of the perimeters of two similar triangles is 4: 3. what are the areas of these triangles if the sum of their areas is 130cm2?

If jklm is a trapezoid, which statements must be true?

Anull hypothesis states that the difference between 8 hours of sleep and 3 hours of sleep has no effect on the number of pictures a student will remember during a picture memory interface test (pmit). examining the mit database, an extremely small t-value of 0.1611 is found. this t-value is much smaller than the smallest t-value on the chart for p-value reference. from this information we can: select one: a. accept the null hypothesis because the p-value obtained shows that the difference between the two groups being tested is not statistically significant b. accept the null hypothesis because the p-value obtained was statistically significant c. reject the null hypothesis because of the p-value obtained d. reject the null hypothesis because the data obtained is statistically significant
