Answer:

400% of 5 = 5 x 400/100 = 20.

20 > 10 and 20 < 100

Hope this helps!

$\frac{1}{a} = \frac{1}{b} + \frac{1}{c} \\ \\ \frac{1}{12} = \frac{1}{b} + \frac{1}{22} \\ \\ \frac{1}{b} = \frac{1}{12} - \frac{1}{22} \\ \\ \frac{1}{b} = \frac{11}{132} - \frac{6}{132} \\ \\ \frac{1}{b} = \frac{11 - 6}{132} \\ \\ \frac{1}{b} = \frac{5}{132} \\ \\ 5b = 132 \\ \\ b = \frac{132}{5} \\ \\ b = 26.4 \\ \\ b = 26$

I hope I helped you^_^

How much do u need to subtract from 41/6 to make 6

dem82 [27]

41/6-5/6 = 36/6
36/6= 6

So 5/6 would need to be subtracted to develop a fraction that divides to 6

Or a population, N = 10,000, μ = 121, and σ = 21. Find to 2 decimal places the z value for

Ugo [173]

Answer:

The z value is - 2.88

Step-by-step explanation:

The formula of the z-score of a population is z = (x¯ - μ)/(σ/ $\sqrt{n}$ )

The given in the problem is:

μ = 121
σ = 21
x¯ = 112.35
n = 49

Let us substitute all of these values in the rule above

$z=\frac{112.35-121}{\frac{21}{\sqrt{49}}}$

Simplify up and down

$z=\frac{-8.65}{\frac{21}{7}}$

$z=\frac{-8.65}{3}$

z = - 2.883333

Round it to 2 decimal places

∴ z = - 2.88

The z value is - 2.88
