Answer:

A

Step-by-step explanation:

sin is opposite/hypotenuse, which is 24/26, simplifying to 12/13

For this case, we have that by definition:

Sin (C) = \frac {24} {26}

That is, the sine of angle C will be given by the leg opposite the angle C divided by the hypotenuse of the traingule.

Sin (C) = \frac {24} {26}

Simplifying:

Sin (C) = \frac {12} {13}

Answer:

Option A

uppose a large telephone manufacturer has a problem with excessive customer complaints and consequent returns of the phones for
vodka [1.7K]

Answer:

The answer is "294.2075".

Step-by-step explanation:

Given:

\hat{p} = 0.5 \\\\1 - \hat{p} = 1 - 0.5 = 0.5\\\\E = 4\% = 0.04\\\\

At 83\% confidence level the z is ,

\alpha  = 1 - 83\% = 1 - 0.83 = 0.17\\\\\frac{\alpha}{2} = \frac{0.17}{2} = 0.085\\\\Z_{\frac{\alpha}{2}} = Z_{0.085} = 1.3722\\\\n = (\frac{Z_{\frac{\alpha}{2}}}{E})^2 \times \hat{p} \times (1 - \hat{p})\\\\

   = (\frac{1.3722}{0.04})^2 \times 0.5 \times 0.5\\\\= (34.305)^2 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.5 \times 0.5\\\\= 1,176.83 \times 0.25\\\\=294.2075

Which equation can be simplified to find the inverse of y = 5x2 + 10?
zmey [24]

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10

Step-by-step explanation:

interchanging the variables

x = 5y^2 + 10

5y^2 +10 = x

5y^2 = x - 10

dividing by 5

5y^2/5 = x/5 + -10/5

y^2 = x/5 + - 10/5

y^2 = x/5 - 2

y = 5 (x-10) 0/5 (sq.rt)

g(5x^2 + 10) = 5x/5

g(5x^2 + 10) = x

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10

Which of the following statements are never true? Select all that apply. Three points are coplanar Two planes meet in exactly on
statuscvo [17]

Answer: Two planes meet in exactly one point

Two lines meet at exactly two points


Step-by-step explanation:

From the given statements there are two statements which are never true :-

1) Two planes meet in exactly one point .

Since when two line meets , they either meet at one point or infinite points (coincidence) , thus its impossible that they will meet at exactly two points.

2) Two lines meet at exactly two points

Since when two planes meet , the intersection of two plane always make a line not a point. Thus its impossible.

11 = 1.375 * 8
22 = 1.375 * 16
33 = 1.375 * 24
Therefore y varies directly with x.
Answer: C ) yes; y = 1.375 x
