Use the given values of n and p to find the minimum usual value μ−2σ and the maximum usual value μ+2σ. Round to the nearest hund

lbvjy [14]

Answer:

μ−2σ = 1,089.26

μ+2σ = 1,097.62

Step-by-step explanation:

The standard deviation of a sample of size 'n' and proportion 'p' is:

$\sigma=\sqrt{\frac{p*(1-p)}{n} }$

If n=1139 and p =0.96, the standard deviation is:

$\sigma=\sqrt{\frac{p*(1-p)}{n}}\\\sigma = 0.001836$

The minimum and maximum usual values are:

$\mu-2\sigma = (p-2\sigma)*n\\\mu+2\sigma = (p+2\sigma)*n$

$\mu-2\sigma = (0.96-2*0.001836)*1139\\\mu-2\sigma = 1,089.26\\\mu+2\sigma = (0.96+2*0.001836)*1139\\\mu+2\sigma = 1,097.62$

-17-5(x+3)=3x plz help

katovenus [111]

Start by distributing the -5 into the x and 3
-17-5x-15=3x
add like terms
-5x-32=3x
add 32 to both sides
-5x=3x+32
subtract 3x from both
-8x=32
divide both by -8
x=-4

Which choice answer is it

fomenos

Answer:

choice 1

Step-by-step explanation:

Given

V = πr²h ( isolate r² by dividing both sides by πh )

$\frac{V}{\pi h}$ = r² ( take the square root of both sides )

$\sqrt{\frac{V}{\pi h} }$ = r ← the positive value of r
