Hi there! Just by looking at the choices, we can eliminate C and D, because those answers don’t make sense and they don’t flow together. 3:5 is equivalent to those like 6:10, 9:15, 12:20, and so on. You can basically add 3 and 5 in order to get the next ratios. The only ratio that works in this problem is B. The answer is B: 9:15.

Answer:

Binomial = 0.8724

Normal approximation = 0.873

Step-by-step explanation:

Given that :

Sample size (n) = 20

p = 0.6

q = 1 - p = 1 - 0.6 = 0.4

.using normal approximation :

Mean = np

Mean (m) = 20 * 0.6 = 12

Standard deviation (s) = √npq

s = √(20 * 0.6 * 0.4) = 2.1908902

Probability of 10 or more lines in use :

p(x ≥ 10)

Applying for correction:

p(x ≥ 10 - 0.5) = p(x ≥ 9.5)

Using the z formula :

Z = (x - m) / s

Z = (9.5 - 12) / 2.1908902

Z = - 1.141

p(Z > - 1.141) = 0.87307 (Z probability calculator)

p(Z > - 1.141) = 0.873

Using the binomial distribution :

P(x = x) = nCx * p^x * (1 - p)^(n-x)

p(x ≥ 10) = p(x = 10) + p(x = 11) +.... + p(x = 20)

Using calculator :

p(x ≥ 10) = 0.87247

= 0.873

If sin(θ -π/2) = 0.73.. find cos (-θ) plz explain how to solve

Temka [501]

Answer:

$cos(-\theta) = -0.73$

Step-by-step explanation:

It is given that:

$sin(\theta -\dfrac{\pi}{2}) = 0.73$

<u>Formula to be used:</u>

$1.\ sin(-x) = -sinx\\2.\ sin(\dfrac{\pi}{2}-x) = cosx\\3.\ cos(-x) = cosx$

Using Formula (1) written above:

$\Rightarrow sin (\theta - \dfrac{\pi}{2})=sin(-(\dfrac{\pi}{2}-\theta ))\\\Rightarrow -sin(\dfrac{\pi}{2}-\theta)$

Now, using Formula (2) written above:

$\Rightarrow -sin(\dfrac{\pi}{2}-\theta) = -cos \theta$

So, we can say that:

$sin(\theta -\dfrac{\pi}{2}) = -cos\theta = 0.73 ...... (1)$

We have to find the value of $cos(-\theta)$ .

Using Formula (3) written above:

$cos(-\theta) = cos\theta$

So, ultimately we need to find the value of $cos\theta$

Using equation (1):

$-cos\theta = 0.73\\\Rightarrow cos\theta = -0.73$

So, the answer is $cos(-\theta) = -0.73$ .
