Sandwich shop customers can choose the bread and meat they want. The table shows the sandwiches that were sold on a given day. there are two types of bread, White bread and whole wheat bread, and three different meat types, Ham, turkey, and tuna. If there is 22 ham sandwiches with white bread, 24 with wheat, 21 with turkey and white bread, 22 with wheat, 25 of white bread with tuna, and tuna with wheat bread, 1.How many sandwiches were sold that day?

2.What is the experimental probability that the next sandwich sold has ham?

3.What is the experimental probability that the next sandwich sold is tuna on wheat bread?

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

linear pair postulates

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
