Answer:

a) 1/4

b) 3/4

c) 1/4

Step-by-step explanation:

Possible outcomes of two tosses of a coin:

There is a total of 4 possible outcomes.

p(event) = (number of desired outcomes)/(total number of possible outcomes)

a) 2 heads

HH <------- 1 desired outcome

p(2 heads) = 1/4

b) at least 1 head

HH \

HT } <------ 3 desired outcomes

TH /

p(at least 1 head) = 3/4

c) no heads

TT <------- 1 desired outcome

p(no heads) = 1/4

Consider the function and its inverse.

Ber [7]

Answer:

The domain of $f(x)$ is restricted to $x\leq 0$ , and the domain of $f^{-1}(x)$ is restricted to $x\geq 4$ .

Step-by-step explanation:

From Function Theory we know that domain of a function is the set of values such that an image exist. Let $f(x) = x^{2}+4$ and $f^{-1}(x) = \sqrt{x-4}$ the function and its inverse, respectively.

At first glance we notice that function is a second order polynomial and every polinomial is a continuous function and therefore, there exists an image for every element of domain.

But domain of its inverse is restricted to every value of x so that $x-4 \geq 0$ , which means that $x\geq 4$ .

Finally, we concluded that following answer offers the best approximation to our result:

The domain of $f(x)$ is restricted to $x\leq 0$ , and the domain of $f^{-1}(x)$ is restricted to $x\geq 4$ .

1. Suppose you have 62 toothpicks and a bunch of rubber bands.

ehidna [41]

Base-ten units are used to represent numbers in blocks

<h3>How to represent the bundle of toothpicks</h3>

The bundle is given as:

Bundle = 62

Rewrite as:

Bundle = 60 + 2

Express 60 as a product

Bundle = 6 * 10 + 2

See attachment for the drawing that represents the bundle

<h3>Ways to interpret the 6 in 62</h3>

The 6 in 62 can be interpreted in the following ways

Way 1: 6 tens
Way 2: 60
