find all integers x satisfying each of the following congruences mod n. if no such x exists, explain why not
zalisa [80]

Answer:

please find the solution:

Step-by-step explanation:

please find the correct question:

Given value:  

\to 4x \equiv  2(mod\ n) \ \ \ \ \ \ \ \ \ \ \ \ _{where} \ \  n=6\\\\\to  4x \equiv  2 (mod 6)

\to 4x-2 should be divisible by 6  we are also given that 0 \leq x < n  and start with x = 0  

\to 4x-2 =-2 which is not divisible by 6  

x= 1  

\to 4x-2 = 2 not divisilble by 6  

x= 2

\to 4x-2 = 6 which is divisible by 6  

x=3  

\to 4x-2 = 10 not divisible by 6

x=4  

\to 4x-2  = 14 not divisible by 6  

x=5

\to 4x-2  = 18 which is divisible by 6  

so such x are x = 2 and x = 5

The sat scores have an average of 1200 with a standard deviation of 120. a sample of 36 scores is selected. what is the probabil
Naya [18.7K]
We first standardise \bar{x}:
P(1224 > \bar{x})=P(\frac{1224-1200}{\frac{120}{ \sqrt{36} }}>\frac{\bar{x}-1200}{\frac{120}{\sqrt{36}}})
which reduces to finding P(Z > 1.2) = 0.115
