Answer:

if I read your screen correctly

$F radius = 5 x {10}^{-8 }$

$Sr radius = 2 x {10}^{-7}$

Step-by-step explanation:

divide the larger one (Sr) by smaller one (F)

the coefficient = 2/5

the exponent = -7-(-8)

can you get the answer from there, don't forget to simplify

All of the ingredients are purchased in bulk sizes. The butter comes in 12-cup containers. How many recipes will each container

Citrus2011 [14]

Answer:

some information is missing, so I looked for similar questions and found the attached image:

since each recipe requires ¹/₂ cup of butter, you are able to make 12 ÷ ¹/₂ = 24 recipes with one container of butter (assuming you have all the other ingredients).

One-half, ¹/₂, is a fraction that can also be written in decimal form as 0.5. Two times ¹/₂ is equal to 1, and similarly, twenty four times ¹/₂ is equal to 12.

According to the National Association of Realtors, the mean sale price for existing homes in the United States in 2011 was $214,

<h3>Answer: 49.85% (second answer choice)</h3>

===========================================

Explanation:

mu = 214300 = population mean of home values

sigma = 41000 = population standard deviation of home values

Compute the z score for the raw score x = 91300

z = (x-mu)/sigma

z = (91300-214300)/41000

z = -123000/41000

z = -3

This tells us the raw score x = 91300 is exactly 3 standard deviations below the mean.

--------------------------

Compute the z score for the raw score x = 214300

z = (x-mu)/sigma

z = (214300-214300)/41000

z = 0/41000

z = 0

This is expected as the raw score x = 214300 is exactly at the mean

--------------------------

Finding P(91300 < x < 214300) is equivalent to computing P(-3 < z < 0)

Recall that the empirical rule states roughly 99.7% of the distribution is within 3 standard deviations of the mean.

In terms of an equation, this means P(-3 < Z < 3) = 0.997 approximately.

Cut 99.7% in half to get (99.7%)/2 = 49.85%

So, P(-3 < Z < 0) = 0.4985 approximately.
