Answer:
A. -1.6; not significant
Step-by-step explanation:
The z-score of a data set that is normally distributed with a mean of and a standard deviation of , is given by:
.
From the question, the test score is: , the mean is , and the standard deviation is .
We just have to plug these values into the above formula to obtain:
.
This simplifies to: .
.
We can see that the z-score falls within two standard deviations of the mean.
Since the value is not significant.
The correct answer is A. -1.6; not significant
Answer:
6165421

whatever you do to 1 side you have to do to the other. add 1662 as the calculation is a minus.
Answer:
$29,005.97
Step-by-step explanation:
Cn = Co * (1 + i)^n
Cn = 104,986.99(1+.05/1)^(1*5)
Cn = 104,986.99(1+.05)^5
Cn = 104,986.99(105)^5
Cn = 104,986.99(1.2763)
Cn = 133,992.96, total money at end
133,992.96-104,986.99= $29,005.97, interest accumulated
Answer:
(3,1) is the midpoint
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(7+-1)/2 = 6/2 =3
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(10+-8)/2 = 2/2 = 1
(3,1) is the midpoint
In predicting the number of ways, there are two methods in probability; combination and permutation. Combination do not care what order it may be whereas permutation cares about the order. In this problem, we can use combination because the grouping of 5 cards is not restricted on what type of cards are to be inn this group. Use the equation:
C = n! / k! (n-k)!
C = 52! / 5! (52 - 5)!
C = 2,598,960
