Answer:

1) 1/10

2) 1/2

3) 1/5

Step-by-step explanation:

1 favorable outcome and 10 total outcomes.

$P(3) = \frac{1}{10}$

5 favorable outcomes and 10 total outcomes

$P(even) = \frac{5}{10} = \frac{1}{2}$

2 favorable outcomes and 10 total outcomes

$P(multiples\ of\ 5) = \frac{2}{10} = \frac{1}{5}$

(csc x - 1) (csc x + 1)

victus00 [196]

<h2>Explanation:</h2>

Here we have the following expression:

$(csc x - 1) (csc x + 1)$

So we need to extend this. Remember that the difference of squares tells us:

$(a-b)(a+b)=a^2-b^2$

So here:

$a=cscx \\ \\ b=1$

Thus:

$(csc x - 1) (csc x + 1)=csc^2x-1 \\ \\ \\ But: \\ \\ cscx=\frac{1}{sinx} \\ \\ \\ Then: \\ \\ csc^2x-1=\frac{1}{sin^2x}-1=\frac{1-sin^2x}{sin^2x}=\frac{cos^2x}{sin^2x}=cot^2x \\ \\ \\ Finally: \\ \\ \boxed{(csc x - 1) (csc x + 1)=cot^2x}$

Nookie1986 [14]

Answer:

We can have 7 fish in fish tank containing 35 gallons of water.

Step-by-step explanation:

Given:

2 fish per 10 gallons

∴ 1 fish can be in = $\frac{10}{2}=5 \ gallons$

To find Number of fish in 35 gallons of water

Number of fish in 35 gallons would be = $\frac{35}{\text{Number of gallons for 1 fish}} = \frac{35}{5}= 7$
