What is the probability each player has a winning?
olganol [36]
You have a 1 in 50 chance (ie A)
Explanation:
Let's start with the first bag. In it sits 5 numbers. So, you have a 1 in 5 chance that the number picked will be yours.

Now, let's consider the second bag. You have 10 different numbers and only one of yours may be picked. Hence, you have a 1 in 10 chance that yours will get picked.

Since we want them simultaneously, we will need to multiply the two probabilities together, yielding a 1 in 50 chance.

Which situation could NOT represent a proportional relationship?
Serhud [2]

Answer:

The weight in x weeks of a puppy that gains 2 pounds per week if it starting weight is 8 pounds.

Step-by-step explanation:

Given:

A proportional relationship is one in which one variable varies directly with the other. Let the dependent variable be y and independent variable be y.

If y is directly proportional to x, then,

y=kx, where, k is a constant of proportionality.

Now, let us check each option and try to express a relationship between them.

Option 1:

The weight in x weeks of a puppy that gains 2 pounds per week if it starting weight is 8 pounds.

Let the weight be represented by W. Initial weight is 8 pounds.

Weight gain per week is 2 pounds. So, weight gain in x weeks is 2x.

Therefore, total weight is, W=8+2x

This is a linear relationship but not a proportional relationship as it is not of the form y=kx. So, option 1 could NOT represent a proportional relationship.

Option 2:

Cost of purchasing 1 pound of bananas is $ 0.55. So, cost of purchasing p pounds of bananas will be C=0.55p. It is of the form y=kx. So, it represents a proportional relationship.

Option 3:

Number of gallons of water in 1 barrel is 50. So, number of gallons in x barrels will be N=50x. It is of the form y=kx. So, it represents a proportional relationship.

Option 4:

Amount earned by an employee in 1 hour is $ 9.25. So, amount earned in h hours will be A=9.25h. It is of the form y=kx. So, it represents a proportional relationship.

Help me please <br> calculate the value of x in the polygon
alisha [4.7K]

Answer:

122.5 degrees

Step-by-step explanation:

A six sided polygon's interior angles sum to

  (n-2)(180) =  (6-2) (180) = 720 degrees

then   x + x + x +     x+10    + 130   + 90 = 720

                          4x = 490        so x = 122.5 degrees
