Answer:

  • Sn = n^2 . . . . . . the pattern
  • {1, 4, 9, 16, 25, 36, 49}

Step-by-step explanation:

The consecutive differences between S-numbers are (by definition) consecutive odd numbers. This by itself indicates that S-numbers are defined by a quadratic formula. As it happens, ...

  Sn = n^2

___

  S1 = 1 . . . . given

  S2 = S1 + 3 = 4

  S3 = S2 + 5 = 9

  S4 = S3 + 7 = 16

  S5 = S4 + 9 = 25

  S6 = S5 +11 = 36

  S7 = S6 +13 = 49

A list of the first 7 S-numbers is ...

  {1, 4, 9, 16, 25, 36, 49}

James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The
Brrunno [24]

Answer:

The correct option is 4.

Step-by-step explanation:

Given information:

Bring lunch : 46 males, 254 females

Buy lunch   : 176 males, 264 females

Total number of peoples is

46+254+176+264=740

Total number of males is

46+176=222

The probability of male is

P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3

Since probability of males is 0.3, therefore options A and C are incorrect.

Total number of persons who buys lunch is

176+264=440

The probability of persons who buys lunch is

P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}

We need to find the probability of P(male | buys lunch).

According to the conditional probability, we get

P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}

P(male | buys lunch)=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}

P(male | buys lunch)=\frac{\frac{176}{740}}{\frac{22}{37}}

P(male | buys lunch)=\frac{2}{5}=0.4

Therefore the correct option is 4.
