Suppose a batch of metal shafts produced in a manufacturing company have a variance of 6.256.25 and a mean diameter of 206206 in

bearhunter [10]

Answer:

Step-by-step explanation:

mean diameter = 206

variance = 6.25

standard deviation = √ variance

σ = √ 6.25 = 2.5

sample size n = 90

z = deviation from mean / (σ / √n)

= 0.3 / (2.5/ √90)

= .3 / .2635

= 1.1385

P value from the table = (.87 - .5 ) x 2

= .37 x 2 .

or 74 % .

It is 7 kilometers from kerrys house to the mall. About what is that distance in miles?

GenaCL600 [577]

Answer:

$\huge\boxed{\approx 4.4 \ \text{miles}}$

Step-by-step explanation:

In order to convert kilometers to miles, we can use a formula, assuming $m$ is miles and $k$ is kilometers.

$m = \frac{k}{1.609}$ .

Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.

$7 \div 1.609 \approx 4.4$

Hope this helped!

If 2^n+2-2^n+1+2^n= C*2^n, find the value of C

maxonik [38]

Answer:

c= 1

Step-by-step explanation:

To get rid of (c) on the right side, simply divide 2^n both side. But first collect like terms on the left side so you will get 2^n + 1 which you will then simplify the like term(2^n) and you will left with c= 1.

Guido is a citizen and resident of Belgium. He has a full-time job in Belgium and has lived there with his family for the past 1

Korvikt [17]

Answer:

Guido stayed in US in 2018 for 180 days which are greater than 31 days.

Guido Stayed in US in 2018 and in 2017 = (180 + 66) > 183 days.

So, yes Guido does meet US Statutory definition in 2018 and stayed 180 days in 2018.

Step-by-step explanation:

Let's find out how many days in total Guido stayed in US in these 3 years 2017, 2018 and 2019.

Year = 2017

Days = 200

Year = 2018

Days = 180

Year = 2019

Days = 70

Total days stayed = 200 + 180 + 70

Total Days Stayed = 450 days.

In U.S, there are two tests are in place and for non-citizen of U.S and for the resident Alien or non - resident Alien status, one must pass one of these two tests, which are as follows:

1. Green Card Test:

2. Substantial Presence Test:

Here, in this problem, Guido is citizen and resident of Belgium. So, will check his criteria according to the substantial presence test.

So, the question is: how many days Guido was present in the U.S in 2018 under resident alien status.

In 2018, Guido stayed in US for 180 days.

So, according to the Substantial Presence test, one must be physically present in US for more than 31 days to be eligible for resident alien status. In addition, in 2018, his total of physical presence in US in 2018 and one third of physical presence in 2017 must be greater than 183 days.

If we see, both conditions are matched in case of Guido.

Guido stayed in US in 2018 for 180 days which are greater than 31 days.

Guido Stayed in US in 2018 and in 2017 = (180 + 66) > 183 days.

So, yes Guido does meet US Statutory definition in 2018 and stayed 180 days in 2018.
