Answer:

Step-by-step explanation:

I'm GUESSING you want to know a value for θ if possible

secθ + tanθ = cosθ/(1 - sinθ)

1/cosθ + sinθ/cosθ = cosθ/(1 - sinθ)

(1 + sinθ)/cosθ = cosθ/(1 - sinθ)

(1 - sinθ)(1 + sinθ) = cos²θ

1 - sinθ + sinθ - sin²θ = cos²θ

1 - sin²θ = cos²θ

1 = cos²θ + sin²θ

which is the unit circle, centered on the origin with radius 1 unit

0 ≤ θ ≤ 2π

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive rea

Orlov [11]

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

Step(i):-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that $\sqrt{p(1-p}\leq \frac{1}{2}$

Step(ii):-

Given margin of error = 2 % =0.02

The margin of error is determined by

$M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }$

$0.02 = \frac{\frac{1}{2} }{\sqrt{n} }$

$\sqrt{n} =\frac{1}{2 X0.02}$

√n = 25

squaring on both sides, we get

n = 625

Thirty seven divided by nine

Sunny_sXe [5.5K]

Answer:

4.11 (rounded to the hundredth place, the actual answer is 4.1(with the one repeating))

Step-by-step explanation:

To solve 37 divided by 9 you have to do long division or you can use a handheld calculator.

To solve it through long division,

9 can go into 3 zero times

9 can go into 37 four times though

9*4 is 36

So subtract 36 from 37, leaving 1.

9 can go into 1 zero times.

Add a zero behind the one and 9 can go into 10 once.

The pattern continues forever, making the answer 4.1(with the one repeating)

or 4.11 (rounded to the hundredth place)

If you need anymore clarification I can certaintly help.
