Molly is on a game show. To win $1,000,000, she must answer this question: What key features are necessary—and how are the features used—to create the sketch of a polynomial function? What is Molly's winning answer? Explain in complete sentences.

Answers

A polynomial function refers to a function expressed by a polynomial, with only positive integer (non-fraction, non roots) values for the exponents, such as:

(a_(1))^(n) + (a_(2))^(n-1) + (a_(3))^(n-2) +...+ a_(n)

Kayla has a bowl of beads that contains 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. She randomly draws a bead from the bowl.The probability of Kayla not drawing a yellow or a green bead is______ %. The probability of Kayla drawing a red or a green bead is______ %.

Answers

a) probability of she not drawing a yellow beads or green beads is probability of she drawing red or white. Red+ white = 30. There are total of 100 beads. That means that asked probability is:
30/100

b) its oposite that result from a) yellow beads + green beads = 70
probability is:  70/100

Answer:

1. 30%

2.46%

Step-by-step explanation:

The probability of Kayla not drawing a yellow or a green bead is  30 %. The probability of Kayla drawing a red or a green bead is  46 %.

Correct for plato! :)

Find the gcf
14abc and 28a^2b^2c^3

Answers

gcf mean great common factor 
so between 14abc and 28a^2b^2c^3 the great common factor will be 

between 14 and 28 is 14 
btw. a and a^2 is a
btw. b and b^2 is b
btw. c and c^3 is c 
---------------------------------
so the gcf will be 14abc

hope helped 

Please help me solve this​

Answer:

C should be the correct answer

Step-by-step explanation:

forgive me if im wrong

Answer:

a, b, c

(all but the last one)

Step-by-step explanation:

a+b+c=180 is true bcuz the sum of interior angles in a triangle is 180

rearrange a+b+c=180 into a+b=180-c

observe that 180-c equals d, so in the equation a+b=180-c replace 180-c with d.

a+b=d   so thats true

we already established that d=180-c  so thats true as well

and the last one is just not true

A fraction reduces to 36. If its denominator is 6x5, what is its numerator?

Answers

If you would like to find the numerator of a fraction, you can do this using the following steps:

denominator ... 6 * 5 = 30
numerator ... x = ?

36 = numerator / denominator
36 = x / 30
x = 36 * 30
x = 1080

The correct result would be 1080.
