The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.

Step-by-step explanation:

The given is,

1243=21

2415=36,

3241=25,

4521=27

Step:1

For, 1243 = 21

Above is solved by,

(1+2)×(4+3)=21

(3)×(7)=21

21=21

For, 2415 = 36

Above is solved by,

(2+4)×(1+5)=21

(6)×(6)=36

36=36

For,3241= 25

Above is solved by,

(3+2)×(4+1)=25

(5)×(5)=25

25=25

For, 4521= 27

Above is solved by,

(4+5)×(2+1)=27

(9)×(3)=27

27=27

For, 3542 = ?

Above is solved by,

= (3+5)×(4+2)

=(8)×(6)

3542=48

Result:

The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.

Answer from: Quest

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule?
