Answer:

<u>25/72</u>

Step-by-step explanation:

Total outcomes :

(5 + 4 + 3)²
(12)²
144 outcomes

P (red twice) :

16/144
1/9

P (blue twice) :

9/144
1/16

P (green twice) :

25/144
5/12

Adding :

1/9 + 1/16 + 5/12
16/144 + 9/144 + 25/144
50/144
<u>25/72</u>

Answer: y = — $\frac{1}{2}$ x + 3

Step-by-step explanation:

The line crosses the y-axis at the point (0,3), making its y-intercept be +3.

The line is going downwards left to right, giving it a negative slope.

The line's slope is — $\frac{1}{2}$ because it is negative and it goes down 1, over 2.

Therefore, the line's equation is y = — $\frac{1}{2}$ x + 3

Amy cut 32 ft of chain into pieces that were each 1/4 ft long. How many of these did Amy have after cutting the chain?

agasfer [191]

128 pieces can be made after cutting the chain

<em><u>Solution:</u></em>

Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long

<em><u>To find: Number of pieces after cutting the chain</u></em>

From given,

$\text{Total length of chain } = 32 \text{ feet }\\\\\text{Length of 1 piece } = \frac{1}{4} \text{ feet }$

Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece

$\text{Number of pieces} = \frac{\text{Total length of chain}}{\text{Length of 1 piece }}$

<em><u>Substituting the values, we get</u></em>

$\text{Number of pieces} = \frac{32}{\frac{1}{4}}\\\\\text{Number of pieces} = 32 \times 4 = 128$

Thus 128 pieces can be made after cutting the chain
