What is the ratio for sine

Sphinxa [80]

Answer:

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Step-by-step explanation:

There is a trigonometric acronym for this which is:

Soh Cah Toa

Soh means that sine is opposite over hypotenuse.

Cah means that cosine is adjacent over hypotenuse.

Toa means that tangent is opposite over adjacent.

Let me actually write these out as fractions:

sine is $\frac{\text{opposite}}{\text{hypotenuse}}$

cosine is $\frac{\text{adjacent}}{\text{hypotenuse}}$

tangent is $\frac{\text{opposite}}{\text{adjacent}}$

Blank 1: opposite

Blank 2: adjacent

Blank 3: opposite

Blank 4: adjacent

Maksim231197 [3]

Answer:

324

Step-by-step explanation:

given that in a poll, 74% of the people polled answered yes to the question "Are you in favor of the death penalty for a person convicted of murder?"

i.e. Sample proportion $p=0.74\\q =1-p =0.26\\$

Margin of error = 4% = 0.04

Confidence level =90%

Z critical value for 90% = 1.645

Margin of error = 1.645 * std error

Hence std error = $\frac{0.04}{1.645} \\=0.0243$

Std error is also equal to

$\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.74(0.26)}{n} } =0.0243\\\sqrt{n} =18..05\\n = 325.83~324$

Sample size should be 324.

The formula is sample size = (Z critical value)^2 (pq)/(Margin of error )^2

Use parallelogram ABCD. What are the values of x and y? x = y =

Tasya [4]

Answer:

x = 17 and y = 10

Step-by-step explanation:

ABCD is a parallelogram

So AB = CD and AD = BC

3x - 9 = 42

3x = 51

x = 17

and

4y - 3 = 37

4y = 40

y = 10

Answer

x = 17 and y = 10

2w^2-11w=-12 a w=3/2 or 4 b w=1 or 12 c w=1 or 7 d w = 2.5 or 6

dlinn [17]

Hey mate !!
Here's your answer !!

2w^2 - 11w = -12
2w^2 -11w + 12 = 0
2w^2 - 8w - 3w + 12 = 0

2w ( w - 4) -3 ( w - 4) = 0
(2w - 3) ( w - 4) = 0

Hence

2w - 3 = 0
2w = 3
w = 3/2

w - 4 = 0
w = 4

Hence value of w are 4 and 3/2

Hope this helps!!
Cheers!!
