Researchers at the university of pennsylvania school of medicine have determined that children under 2 years old who sleep with the lights on have a 32% chance of becoming myopic before they are 16. children who sleep in darkness have a 25% probability of becoming myopic. a survey indicates that 20% of children under 2 sleep with some light on. find the probability that a random child under 2 will become myopic before reaching 16 years old.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
