If 3, 6, 9, 12, 15, and 18 are multiples of 3 between 1 and 20, and 5, 10, 15 and 20 are multiples of 5 between 1 and 20, then you add the amount of multiples together to get 10.

10 over 20 as a fraction can be simplified to 1 over 2 which is 50%.

This means that there is a 50% chance of drawing out a multiple of 3 or 5.

I hope this helps

Which statement about the polynomial function g(x) is true?
yKpoI14uk [10]

When leading coefficient is 1 , the root will be an integer for g(x) = 0

Option 4 is the right answer.

<h3>What is a Polynomial Function ?</h3>

Functions of independent variable in which the variable can appear more than once with different powers.

\rm g(x) = a_n x^n + a_{n-1}x^{n-1} + ................+ a_o

Let this represents the polynomial function

where \rm a_n \; is\;the \;leading \; coefficient \; a_o \; is \;the\;last \;term

Then the according to rational root theorem ,

The root of the function is given by

\rm \dfrac{p}{q} = \dfrac{factor \;of\; the\; last\; term}{factor \;of \;the\; leading coefficient}

So when leading coefficient is 1 , the root will be an integer for g(x) = 0

Option 4 is the right answer.

Could some one plz help me with this question
zhuklara [117]

Answer:

A

Step-by-step explanation:

The formula for this type of interest is A=P(1+\frac{r}{n})^{nt}, where A is the total amount, P is the initial investment, x is the interest rate, n is the amount of times that the investment is compounded a year, and t is the amount of years. Plugging in the numbers given, you get:

A=1800(1+\frac{0.025}{2})^{2\cdot 12}=

1800(1.0125)^{24}\approx 2425.23

Now, she invests this into a new account, and you can set up the following equation:

A=2425.23(1+\frac{0.04}{12})^{12\cdot 7}=

2425.23(1.0033333)^{84}\approx 3207.40, or option A.

Hope this helps!
