Use the function below to find F(2).<br> F(t) = 2•1/2^3t

navik [9.2K]

Answer:

$F(2)= \frac{1}{32}$

Step-by-step explanation:

The given function is

$F(t) = 2 \cdot \: \frac{1}{{2}^{3t} }$

To find F(2), we substitute t=2 into the function.

This means that wherever we see t, we put 2

$F(2) = 2 \cdot \: \frac{1}{{2}^{3 \times 2} }$

We multiply the exponent in the denominator to get:

$F(2) = 2 \cdot \: \frac{1}{{2}^{6} }$

We evaluate to get:

$F(2) = 2 \cdot \: \frac{1}{64}$

We now cancel the common factors to get:

$F(2) = \frac{1}{32}$

Inessa [10]

Answer:

$\begin{array}{cccc}&\text{Own cat}&\text{Do not own cat}&\text{Total}\\\text{Own dog}& 45 & 125 & 170\\\text{Do not own dog}& 78 & 52 & 130 \\\text{Total}& 123 & 177 &300\end{array}$

Step-by-step explanation:

From the table you can see that

45 customers own cat and dog;
78 own only cat, then 78+45=123 customers own cat;
125 own only dog, then 125+45=170 customers own dog;
52 own neither cat, nor dog;
78+45+125+52=300 customers in total;
300-123=177 customers do not own cat;
300-170=130 customers do not own dog.

Two-way table is

$\begin{array}{cccc}&\text{Own cat}&\text{Do not own cat}&\text{Total}\\\text{Own dog}& 45 & 125 & 170\\\text{Do not own dog}& 78 & 52 & 130 \\\text{Total}& 123 & 177 &300\end{array}$

Find the distance between the two numbers on a number line. Write your answer as a fraction in simplest form. - 7/9, - 2/9 The d

Nesterboy [21]

The distance between the two points on the number line is of $\mathbf{\frac{5}{9}}$ units.

-------------------------------------------

The distance between two numbers on the number line is given by the <u>subtraction of the greater by the smaller number.</u>
The greater number is $-\frac{2}{9}$
The smaller is $-\frac{7}{9}$ .
The distance is:
