Let p: x = 4 let q: y = −2 which represents "if x = 4, then y = −2”? p ∨ q p ∧ q p → q p ↔ q

C. p → q

Step-by-step explanation:

We are given that,

'p' is represented by 'x = 4' and 'q' is represented by 'y = -2'.

That is, we have,

p: x = 4

q: y = -2

The given statement is, 'If x = 4, then y = -2'.

This means that whenever x = 4, then y = -2.

That is, 'x = 4 implies y = -2'.

Thus, it will be represented by p → q.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
