You know the product will be greater than the two factors because multiplication always makes the numbers greater. So 2x12 is 24 and that is greater than the two factors

Afirm’s marketing manager believes that total sales X can be modeled using a normal distribution with mean m ¼ $2.5 million and
Ugo [173]

Answer: 0.0475

Step-by-step explanation:

Given :  A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.

Where , Population mean : \mu=2.5\text{ million}=2.5\times1000000=2500000

Standard deviation : \sigma=300000

To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.

∵ z=\dfrac{x-\mu}{\sigma}

Then , for x= 3,000,000

z=\dfrac{3000000-2500000}{300000}=1.67

Then , the  probability that the firm’s sales will exceed $3 million is given by :-

P(z>1.67)=1-P(z

Hence, the probability that the firm’s sales will exceed $3 million = 0.0475

Help guys with the question
Naya [18.7K]

Answer:

\sin\Big(\dfrac{\theta }{2}\Big) = \dfrac{2\sqrt 5}{5}

Step-by-step explanation:

\cos(2x) = \cos^2 x-\sin^2 x = 1-2\sin^2 x \\ \\ \cos(x) = 1-2\sin^2 (\frac{x}{2}) \\ \\ \Rightarrow \sin^2 (\frac{x}{2}) = \dfrac{1-\cos(x)}{2}\\ \\ \sin(\frac{x}{2}) = \pm \sqrt{\dfrac{1-\cos(x)}{2}},\quad x\in [\frac{3\pi }{2},\pi] \Rightarrow \frac{x}{2}\in [\frac{3\pi}{4},\frac{\pi}{2}]\\ \\ \Rightarrow \sin(\frac{x}{2}) > 0 \Rightarrow \sin(\frac{x}{2}) = \sqrt{\dfrac{1-(-\frac{3}{5})}{2}} \Rightarrow \sin(\frac{x}{2}) = \sqrt{\dfrac{8}{10}}=\dfrac{2\sqrt 2}{\sqrt{10}} = \\ \\ =\dfrac{2\sqrt 5}{5}

jeka57 [31]

Answer:

-n + 2 m + 2

Step-by-step explanation:

Simplify the following:

(-2 n + 4 m + 4)/2

Factor 2 out of -2 n + 4 m + 4:

(2 (-n + 2 m + 2))/2

(2 (-n + 2 m + 2))/2 = 2/2×(-n + 2 m + 2) = -n + 2 m + 2:

Answer:  -n + 2 m + 2

Select the proper order from least to greatest for 2/3 , 7/6 , 1/8 , 9/10
dmitriy555 [2]
2/3 as a decimal is 0.66/0.6, 7/6 as a decimal is 1.16, 1/8 as a decimal is 0.125, and 9/10 as a decimal is 0.9

I guess you could put those in least to greatest order. I hope this helped !!
