Which types of dilation are the given scale factors?

Mathematics
2 answers:
Neporo4naja [7]3 years ago

Answer:

−4  is an expansion; 2.5  is an expansion; 2/3  is a contraction; and −3/4 is a contraction.

Step-by-step explanation:

In a dilation, a scale factor greater than 1 or less than -1 is an expansion.  It will make the figure larger.  This means that -4 is an expansion, since it is less than -1, and 2.5 is an expansion, since it is greater than 1.

A scale factor that is greater than -1 but less than 1 will be a contraction.  It will make the figure smaller.  This means that 2/3 is an expansion, since it is less than 1, and -3/4 is a contraction, since it is greater than -1.

Donavan and Jones are randomly choosing chalices to drink from. 4 of the chalices contain purified water, 5 contain spoiled milk
Arlecino [84]

Answer:

0

Step-by-step explanation:

Chalice with purified water = 4

With spoiled milk = 5

With flat soda = 6

Probability of Jones drinking from a chalice with purified water after Donovan had drank from 3 = 1/3

Probability = required outcome / Total possible outcomes

Total possible outcomes = (4 + 5 + 6) = 15

After Donovan drinks 3 :

Total possible outcomes = (15 - 3) = 12

If the probability of Jones choosing a chalice with purified water is 1/3 then :

(Required outcome / Total possible outcomes) =1 /3

(Required outcome / 12) = 1 / 3

Required outcome * 3 = 12

Required outcome = 12 / 3

Required outcome = 4

Therefore, since initial number of chalice with purified water is 4,

4 - 4 = 0

Then Donovan did not drink from a chalice containing purified water.
