Step-by-step explanation:
The correct amount taken from the account for car wash membership fee is shown below:
−4|25| = −$100
What is the amount subtracted from the account on the account balance?
The amount subtracted has a negative impact on the account balance because it reduces the account balance as it is an expense or debit transaction unlike a credit that increases the balance
$25 is spent every month, which means -$25 taken from the account every month
total amount deducted for 4 months=4*-$25
total amount deducted for 4 months=-$100
The correct option which indicates -$100 is −4|25| = −$100

Answer:
Step-by-step explanation:
Researchers measured the data speeds for a particular smartphone carrier at 50 airports.
The highest speed measured was 76.6 Mbps.
n= 50
X[bar]= 17.95
S= 23.39
a. What is the difference between the carrier's highest data speed and the mean of all 50 data speeds?
If the highest speed is 76.6 and the sample mean is 17.95, the difference is 76.6-17.95= 58.65 Mbps
b. How many standard deviations is that [the difference found in part (a)]?
To know how many standard deviations is the max value apart from the sample mean, you have to divide the difference between those two values by the standard deviation
Dif/S= 58.65/23.39= 2.507 ≅ 2.51 Standard deviations
c. Convert the carrier's highest data speed to a z score.
The value is X= 76.6
Using the formula Z= (X - μ)/ δ= (76.6 - 17.95)/ 23.39= 2.51
d. If we consider data speeds that convert to z scores between minus−2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?
The Z value corresponding to the highest data speed is 2.51, considerin that is greater than 2 you can assume that it is significant.
