Answer:

Property of additive inverse

Step-by-step explanation:

The additive inverse of a number a is -a as:

a + (-a) = 0 = (-a) + a

So, Susan tried to add the additive inverse of her subtrahend 91.

Let's see how it works:

(200-91) + 91 = 200 + (-91 + 91)    (associative property of addition)

= 200 + 0   (additive inverse property)

= 200, the original number.

Hence, her check is correct.

This strategy works because if you subtract one number from another the sum of the two numbers should be the that is being subtracted from. (In this case, it's 200)

Answer: Binomial distribution

Step-by-step explanation:

The binomial appropriation is a likelihood circulation that sums up the probability that a worth will take one of two free qualities under a given arrangement of boundaries or suspicions. The hidden suspicions of the binomial dispersion are that there is just a single result for every preliminary, that every preliminary has a similar likelihood of achievement, and that every preliminary is totally unrelated, or autonomous of one another.

6) What are ED and FD?
kolezko [41]

Answer:

ED = 12 and FD = 24

Step-by-step explanation:

See the attached diagram.

The perpendicular distance between the three parallel lines are same i.e. AB = BC = 8

Therefore, the parallel lines will divide any transverse line ( say FD ) in 1 : 1 ratio i.e. will divide equally.

Therefore, FE = ED = 12 units.

Again, FD = FE + ED = 12 + 12 = 24 units. (Answer)

How can you represent and summarize data in a dot plot?
krek1111 [17]
In a dot plot, each one of the dots represents a value in the data set. When there are multiple values at a particular number, the dots just get stacked on top of each other. Using the dots in the plot, you can find the mean, median, mode or any other statistic that you need to summarize the data.
