Answer:
-2
Step-by-step explanation:
Y=3x-2
y=3x0-2
y=-2
Answer:
Its 2 lol
Step-by-step explanation:
The domain of the function for this case is given by all the values of x for which the function is defined.
We have then that the domain for this case is given by:
x> -2
Equivalently:
(-2, inf)
Answer:
x> -2
option 1
Answer:
The probability that sample mean differ the true greater than 2.1 will be 2.8070 %
Step-by-step explanation:
Given:
Sample mean =46 dollars
standard deviation=8
n=53
To Find :
Probability that sample mean would differ from true mean by greater than 2.1
Solution;
<em>This sample distribution mean problem,</em>
so for that
calculate Z- value
Z=(sample mean - true mean)/(standard deviation/Sqrt(n))
Z=-2.1/(8/Sqrt(53))
Z=-2.1*Sqrt(53)/8
Z=-1.91102
Now for P(X≥2.1)=P(Z≥-1.91102)
Using Z-table,
For Z=-1.91
P(X>2.1)=0.02807
