Do all parallelograms have diagonals that are lines of symmetry?

Mathematics

Yes, because if you break the word "parallelogram up, it is "parallel"  so parallel means all sides are parallel. To asnwer your question yes.
But they don't necessarily always have to be diagonal. they can be straight as long as they're parallel.

Scores of two school basketball teams are recorded. The mean of Team A is 68. The mean of Team B is 67. What conclusion can you
Leto [7]

The conclusions that can be drawn are 3, two of a direct type and the other of an indirect type.

The direct ones are the values. Team A has an average of 68 points per game, which means that it has a good point average and, in the same way, team B, which has an average of 67, which is still a good point average per game.

The hint is the comparison of both teams, and that is that team A is one point above team B, which in terms of points per game makes them better.

What are the standard form and the factored form of the function?
LiRa [457]

Answer:

f(x)= -(x^3+10x^2-275x-1500)  Standard

f(x)= -(x+20)(x+5)(x-15)

Step-by-step explanation:

The factored form of the equation is:

(x+20)(x+5)(x-15)=f(x)  Each of the zeroes are where the graph crosses the x-axis.

The expanded form of the equation is found by using FOIL on the equations above:

-x^3+10x^2-275X-1500

The leading coefficient is negative because the graph rises to the left and falls to the right.

kobusy [5.1K]

Answer:

D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95 percent confidence interval (20.1,23.9)

We are 95% sure that the population mean(that is, the mean for all children in the program) is in this interval. So the correct answer is given by option D.
