Afrozen yogurt shop offers 10 different flavors of yogurt and 15 different toppings. how
many double­dip sundae combinations can be created with 1 topping? one yogurt
flavor may be used for both dips.

The number of double dip sundae that can be created with 1 topping is:

                                     825

Step-by-step explanation:

Since, there are 10 different flavors and same flavor can be used for both the dips.

Also, there are a total of 15 different toppings.

Hence, the number of different double dip sundae that can be created with 1 topping is:

                                825

( Since, the order in which the two sundae are placed does not matter. Hence, we need to use the method of combination.

As denotes the number of ways of choosing of 2 different toppings from the 10 flavors and the addition 10 term represent the 10 cases case in which both the dips are of same flavor

Hence,

)

answer: 25 is the correct answer

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
