Answer:
Commutative property of multiplication
Step-by-step explanation:
Properties of Multiplication:
Commutative:
Multiplying two or more factors in a different order.
ex: 2 x 4 x 5 = 2 x 5 x 4
Associative:
Multiplying factors in parenthesis with different grouping. usually to make the problem simpler.
ex: (13 x 4) x 25 = 13 x (4 x 25)
Distributive:
Distributing a multiplicand to factors in parenthesis.
ex: 2(4 - 1) = 2(4) - 2(1)
ex: 2(8+7) = 2(8) + 2(7)

Answer:

Step-by-step explanation:
Given
Stot A:

Defective = 3%
Store B

Defective = 4%
Required
Determine the probability a product received is defective.
First, we calculate the probability that the defective product is from store A


Convert to decimals

Next, we calculate the probability that the defective product is from store B



The product may come from either stores.
So, the probability of having a defective product is:



The answers is 95 to proof multiply 95 by 9 is equal to 855
Answer:
a) see the attached
b) -0.1213
c) 0.0653
d) 0.0171
e) EOC
Step-by-step explanation:
a) The graph shows the mean and the values at ±1, ±2, and ±3 standard deviations from the mean. Each mark differs from the one below by the value of the standard deviation, 36.18. The central mark is the mean, 704.39.
__
b) As you know, the z-score is computed from ...
z = (x -µ)/σ
z = (700 -704.39)/36.18
z = -0.1213
__
c) Same formula, different numbers.
z = (22 -21.65)/5.36
z = 0.0653
__
d) Likewise, ...
z = (530 -528)/117
z = 0.0171
__
e) EOC would be the easiest. The required score has the lowest z-value, so the applicant only needs to do better than a smaller number of peers.
Actually, the answer to this depends on <em>why</em> the thresholds vary. If we assume that the threshold on each test is set appropriate to the desired knowledge and ability, the test-taker would find his knowledge and ability allows him to do better on the ACT than on the other tests.
On the other hand, if the scores are representative of test taker populations all with the same knowledge and ability, less of that knowledge is required to achieve the necessary score on the EOC.
