Although, in general, you cannot know the sampling distribution of the sample mean exactly, by what distribution can you often approximate it? (a) reverse j-shaped (b) normal (c) j-shaped (d) uniform

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
