PLEASE HELP ME. There is 2 questions
andrey2020 [161]

Answer:

If i did the math correctly the answer to number 9 is a.5 and number 10 is c. Vanilla and German chocolate cupcakes represent about 21% of total sales

Step-by-step explanation:

for number 9 you write down each of the numbers with a dot above them. how many dots represents how many times you repeat the number. you then add it together and divide by the amount of numbers you added together. so in this case it would be 65 ÷ 12. this ends up being 5.41 but you'd round down to 5.

for number 10 you write out how many each flavor sold. then you put those numbers over the total cupcakes sold. divide the denominator by 100 and then divide the numerator by that number. then that gives you the fractions of the percent each one was. the german chocolate and the vanilla added together is almost exactly 21% of the sales

If a(x)=2x-4 and b(x) =x+2, which of the following expressions produces a quadratic function?
ZanzabumX [31]

Answer:

(ab)(x)

Step-by-step explanation:

The complete question in the attached figure

we have

a(x)=2x-4\\b(x)=x+2

we know that

(ab)(x) is equal to the product of a(x) and b(x)

so

(ab)(x)=(2x-4)(x+2)

Applying distributive property

(ab)(x)=2x(x)+2x(2)-4(x)-4(2)

(ab)(x)=2x^2+4x-4x-8

(ab)(x)=2x^2-8

This is a quadratic equation

The other expressions not produce a quadratic equation
