1. Which property is illustrated by the statement?(statement below)

bearhunter [10]

1. 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.

2. 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.

<h3>What is the Commutative Property of Multiplication?</h3>

The commutative property of multiplication states that the arrangement of change of numbers that you want to multiply does not change what you would get as the product.

For example, a × b = b × a.

In the same vein, 8(-5/6) = (-5/6)8 illustrates the commutative property of multiplication.

<h3>What is the Commutative Property of Addition?</h3>

The commutative property of addition also states that the order or arrangement of addends will not change the sum you would get.

For example, 3 + 2 = 2 + 3.

Therefore, the statement, 5.4 + 3 = 3 + 5.4 illustrates the commutative property of addition.

7 . Sampling distribution of the difference between two means A statistician is interested in the effectiveness of a weight-loss

UkoKoshka [18]

Answer:

0.229

Step-by-step explanation:

Given that the difference between the two sample means follows anormal distribution with a mean of11.00 and standard deviation equal to1.4387

A statistician is interested in the effectiveness of a weight-loss supplement. She randomly selects two independent samples. Individuals in the first sample of size n1 = 24 take the weight-loss supplement. Individuals in the second sample of size n2 = 21 take a placebo. Individuals in both samples follow identical exercise and diet programs. At the end of the study, the statistician measures the weight loss (in percent) of each participant.

We find that mean difference actual = 13-2 = 11

Probability that difference >12 =P(Z> $\frac{12-11}{1.3487} \\$ )

=P(Z>0.742)=.0.229

A college library has five copies of a certain text on reserve. Three copies (1, 2, and 3) are first printings, and the remainin

dezoksy [38]

Answer:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

A ={(4), (5)}

Step-by-step explanation:

Given that:

Among the three copies, (1,2,3) are the first printings, and (4,5) are the second printings.

A student who examines these books in random order stops when a second printing has been selected.

Thus, we can compute the sample space associated with these experiments as:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

Suppose A represents the event that we must examine exactly one book.

Then the outcomes of A are:

A ={(4), (5)}
