Suppose point z is halfway between point w and x a standard numberline, and point x is halfway between points z and y. Where is
Delicious77 [7]

Answer:

The point w is located at -4/3

Step-by-step explanation:

Point z is halfway between point w and x

Point x is halfway between point z and y

Point z is located at 1/3 and point y is located at 11/3

Please refer to the number line attached

Then the x is located at the mid-point of z and y

x = \frac{z+y}{2} \\\\x = \frac{\frac{1}{3}+ \frac{11}{3} }{2}

x = 2

Since z is the mid-point of w and x

z = \frac{w+ x }{2}\\\\\frac{1}{3}  = \frac{w+ 2 }{2}\\\\\frac{2}{3}  = w+ 2 \\\\w = \frac{2}{3} - 2\\\\w = -\frac{4}{3}

Therefore, the point w is located at -4/3

When you multiply expressions with the same base, you ______ the exponents. Add multiply
e-lub [12.9K]

Answer:

  ... you <u>add</u> the exponents

Step-by-step explanation:

An exponent is a way of showing repeated multiplication. For example, ...

  x^2 means x·x

and

  x^3 means x·x·x

If we multiply these two expressions together, we get ...

  (x^2)·(x^3) = (x·x)·(x·x·x) =  x·x·x·x·x

This is a product in which x appears as a factor 5 times, so we can write it using an exponent as ...

  x·x·x·x·x = x^5

___

That is, when we multiply the expressions, we add the numbers of times the factor appears in the product:

  2 + 3 = 5

  x^2 · x^3 = x^(2+3) = x^5

Courtney is ordering nachos at a restaurant, and the server tells her that she can have up to three toppings: pico de gallo, oni
aalyn [17]

Answer:

Probability = \frac{1}{9}

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

Probability = P(Onion)\ and\ P(Steak) --- because the events are independent

P(Onion) = \frac{n(Onion)}{Total}

P(Onion) = \frac{1}{3}

P(Steak) = \frac{n(Steak)}{Total}

P(Steak) = \frac{1}{3}

So, we have:

Probability = P(Onion)\ and\ P(Steak)

Probability = P(Onion)\ *\ P(Steak)

Probability = \frac{1}{3} * \frac{1}{3}

Probability = \frac{1}{9}
