Suppose y varies directly with x and inversely with z. When x= 65 and z=5​, then y= 26. Find the constant of variation and the e
Doss [256]

Answer:y = 65x/z

Step-by-step explanation:

Suppose y varies directly with x and inversely with z. It means that as y increases or decreases, y increases or decreases while z decreases or increases respectively.

In order to remove the variation symbol and replace with an equation symbol, we would introduce a constant of variation, k. It becomes

y = kx/z

When x= 65 and z=5​, then y= 26. We would substitute these value to get the constant of variation, k. It becomes

26 = 65k/5

65k = 65

k = 1

The equation of combined variation will be

y = 65x/z

Answer:

P(rolling a multiple of 3)= 1/3

Step-by-step explanation:

Multiples of 3 in between 1-6 ( there are six numbers on a dice, from one to six) include 3 and 6. These give you two out of six outcomes with multiples of 3. Probability of an outcome is calculated by

(number of favorable outcomes/all possible outcomes)

There are only two favorable outcomes in this event, 3 and 6.

And there are 6 outcomes due to there being 6 sides on a dice.

Substitute the numbers in to get (2 favorable/6 possible) >> (2/6)

then simplify by dividing top and bottom number by two to get (1/3)

If you are rolling it one time, then there is no need to do additional work.
