Elena must have substracted 1/2x from both sides of the equation.

Lin must have multiplied both sides of the equation by 2

Explanation

The equation given is

$\frac{1}{2}x+3=\frac{7}{2}x+5$

For Elena to have arrived at

$3=\frac{7}{2}x-\frac{1}{2}x+5$

Then Elena must have substracted 1/2x from both sides of the equation.

That is;

$\begin{gathered} \frac{1}{2}x+3=\frac{7}{2}x+5 \\ \text{Substracting }\frac{1}{2}x\text{ from both sides of the equation will give Elena first step} \\ \frac{1}{2}x+3-\frac{1}{2}x=\frac{7}{2}x+5-\frac{1}{2}x \\ 3=\frac{7}{2}x-\frac{1}{2}x+5 \end{gathered}$

For Lin to have arrived at

$x+6=7x+10$

It shows Lin must have multiplied both sides of the equation by 2

That is;

$\begin{gathered} \frac{1}{2}x+3=\frac{7}{2}x+5 \\ \text{Multiply both sides of the equation by the lowest common mutiple } \\ \text{of the denominator which is 2.} \\ \frac{1}{2}x(2)+3(2)=\frac{7}{2}x(2)+5(2) \\ x+6=7x+10 \end{gathered}$

Determine whether or not the distribution is a discrete probability distribution and select the reason why or why not. x −3 4 7

natta225 [31]

Answer:

The given probability distribution is a discrete probability distribution.

Step-by-step explanation:

We are given the following in the question:

x: 3 4 7

P(X=x): 0.19 0.3 0.51

Property of discrete probability distribution:

$\displaystyle\sum P(x_i) = 1$

If the given probability distribution satisfies this property then, it is a discrete probability distribution.

$\displaystyle\sum P(x_i)\\\\= 0.19+0.3+0.51 \\= 1$

Thus, it satisfies the property for a discrete probability distribution.

Thus, the given probability distribution is a discrete probability distribution.

Elena L [17]

Answer:

10 feet

Step-by-step explanation:

18 × 2 = 36

56 - 36 = 20

20 ÷ 2 = 10

To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56
