Answer: 8/15

Step-by-step explanation: Tangent is opposite/adjacent

The hypotenuse, the longest side of a triangle which is 17. The adjacent side is the second longest which is 15. And the opposite is the shortest or the base of a triangle which is 8.

For the future, remember these:

Sin = opposite/hypotenuse

Cos = adjacent/hypotenuse

Tan = opposite/adjacent

Therefore, tan is 8/15.

Hope this helps.

Answer:

The number of weeks required = 216 weeks

Step-by-step explanation:

Given that:

Margin of Error E = 200

Confidence interval = 95% = 0.95

Level of SIgnificance = 1 - C.I

= 1 - 0.95

= 0.05

Standard deviation = 1500

The Critical value for Z :

$Z_{\alpha/2} =Z_{0.05/2} \\ \\ = Z_{0.025} = 1.96$

The number of weeks( i.e the sample size (n) ) required is :

$n = (\dfrac{Z_{\alpha/2} \times \sigma}{E})^2$

$n = (\dfrac{1.96 \times 1500}{200})^2$

$n = (14.7)^2$

n = 216.09

n ≅ 216 weeks

WHich choice is equivalent to the expression below? √-125

olasank [31]

Answer:

Final simplified form is $5\sqrt{5}i$

Step-by-step explanation:

We have been given an expression $\sqrt{-125}$

Now we need to simplify $\sqrt{-125}$ and check which choice matches with simplified form of $\sqrt{-125}$ .

You missed to provide the choices but still we simplify that.

$\sqrt{-125}$

$=\sqrt{-5*5*5}$

$=5\sqrt{-5}$

When there is negative sign inside square root then we replace that by "i" iota.

$=5\sqrt{5}i$

Hence final simplified form is $5\sqrt{5}i$
