Answer:

I don't 100% know but I think you could spin 99 times and record the data and compare it with the theoretical probabillity of 33 times per color for 99 spins

Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

Let's first establish the simple interest formula which we will require to solve this problem as displayed below:

Simple Interest = Principal × Rate of Interest × No. of Time Periods

I = PRN

Now let's substitute the values from the problem into this formula as displayed below:

I = $90

P = ?

R = 6%

N = 3 years

I = PRN

90 = P × 0.06 × 3

P = 90 / 0.06 × 3

P = 90 / 0.18

P = $500

ANSWER:

As the principal and the amount borrowed is the same, Claire borrowed $500. Therefore, the answer is:

D ) $500

Which property would be useful in proving that the product of two rational numbers is ALWAYS rational? A) a b + c d = ad + bc bd

Mademuasel [1]

Answer:

Step-by-step explanation:

So we need to understand what is rational numbers?

Rational number which can be written under this form: $\frac{x}{y}$ when x any are both integers and y $\neq 0$

The question here is : Which property would be useful in proving that the product of two rational numbers. In math, when we talk about the product of at least two number, it implies to the multiplication in the operation.

Here, only answer C: $\frac{a}{b} *\frac{c}{d} = \frac{ac}{bd}$ with the condition $b\neq 0 and d \neq 0$ and a, b, c and d are integers. Product of two integers is always an integer..

Answer:

Option B

Step-by-step explanation:

we have

$f(x)=x^{3}-x^{2}-9x+9$

we know that

The vertical line test is a visual way to determine if a curve is a function or not. A function can only have one value of y for each unique value of x

In this problem

The given function passes the vertical line test

therefore

f(x) is a function

The Horizontal Line Test is a test use to determine if a function is one-to-one

If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.

In this problem

The given function fails the horizontal line test

because for f(x)=0 x=-3, x=-1, x=3

therefore

It is no a one-to-one function
