Coordinate plane with quadrilaterals ABCD and EFGH with A at 0 comma 0, B at 2 comma 0, C at 3 comma negative 2, D at negative 1

charle [14.2K]

Answer:

No, quadrilaterals ABCD and EFGH are not similar because their corresponding segments are not proportional

Step-by-step explanation:

Corresponding sides have the same slope, so corresponding angles are congruent.

Side AB is 1/2 the length of side EF; side BC is equal to the length of FG, so corresponding sides are not proportional.

The two quadrilaterals are not similar because their corresponding segments are not proportional (last choice).

Find and equation for the line that passes through the points (-6,-4) and (4,4).

Ghella [55]

We have (x-4)/(-6-4) = (y-4)/(-4-4);
(x-4)/(-10) = (y-4)/(-8);
(x-4)/5 = (y-4)/4;
4x-16 = 5y-20;
4x - 5y + 4 = 0;

The distribution of the amount of money in savings accounts for Florida State students has an average of 1,200 dollars and a sta

Anestetic [448]

Answer:

By the Central Limit Theorem, the sampling distribution of the sample mean amount of money in a savings account is approximately normal with mean of 1,200 dollars and standard deviation of 284.6 dollars.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
