<span>Y is directly proportional to x^2. It could be represented by the expression:

y </span>α x^2

We can make it into an equality by inserting the proportionality constant, k.

y = kx^2

k would be constant for any value of y with a corresponding value of x. We solve the problem by this concept as follows:

y1/(x1)^2 = y2/(x2)^2
10/(x1)^2 = y2/(x1/2)^2
10/4 = y2

Therefore, when the value of x is halved, y is equal to 10/4.

There is a spinner with 14 equal areas, numbered 1 through 14. If the spinner is spun one time, what is the probability that the

vfiekz [6]

Answer:

Probability that the result is a multiple of 4 or a multiple of 3= 0.428

Step-by-step explanation:

The spinner is divided into 14 equal areas.

Probability of an event= $\frac{number of favourable outcomes}{total number of outcomes}$

For favourable events,result should be a multiple of 3 or 4.

All the possible outcomes are=1,2,3,4,5,6,7,8,9,10,11,12,13,14

Multiples of 3=3,6,9,12

Multiples of 4=4,8,12

Hence the favourable outcomes are=3,4,6,8,9,12

Number of favourable outcomes=6

Total number of outcomes=14

Probability= $\frac{6}{14}$

=0.428
