Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day.

VladimirAG [237]

Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.

Step-by-step explanation:

Today, Lin's sister's balance is -$2.67

She gets charged $5.95 per day.

There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times

So her balance after 14 days will be:

Balance = -$2.67 - $5.95*14 = -$85.97

When she charges the $430 in the account, her balance will be:

Balance = -$85.97 + $430 = $344.03

So now she has a positive balance, which means that the bank does not charge her anymore.

WINSTONCH [101]

Answer:

a) see attached

b) see attached

Step-by-step explanation:

There is existence of outlier in the Ni data and there is none is Cr data.

# You can try this out in R programming

cr = c(34, 1, 511, 2, 574, 496, 322, 424, 269, 140, 244, 252, 76, 108, 24,

38, 18, 34, 30, 191)

Ni = c(23, 22, 55, 39, 283, 34, 159, 37, 61, 34, 163, 140, 32,

23, 54, 837, 64, 354, 376, 471)

par(mfrow=c(1,2))

hist(cr, col='green')

hist(Ni, col='brown')

par(mfrow=c(1,2))

boxplot(cr, main = 'Boxplot of Cr')

boxplot(Ni, main = 'Boxplot of Ni')

Identify the 12th term of a geometric sequence where a1 = 8 and a6 = −8,192.

vodka [1.7K]

Geometric sequence
$a_{n}=a_{1}*r^{n-1}$
r=common ratio
a1=first term
find r

a1=8
a6=-8192
$-8192=a_{6}=8*r^{6-1}$
$-8192=8*r^{5}$
divide both sides by 8
$-1024=8*r^{5}$
take 5th root of both sides
-4=r
sub
$a_{12}=8*(-4)^{12-1}$
$a_{12}=8*(-4)^{11}$
$a_{12}=8*-4194304$
$a_{12}=-33554432$

Left to Right

Algebra I

Function Notation
Interval Notation - [a, b]
Average Rate of Change: $\displaystyle \displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

g(x) = 4x

Interval [1, 5]

Step 2: Find Change

Substitute in function and points [Average Rate of Change]: $\displaystyle \displaystyle \frac{4(5) - 4(1)}{5 - 1}$
[Fraction] Multiply: $\displaystyle \displaystyle \frac{20 - 4}{5 - 1}$
[Fraction] Subtract: $\displaystyle \displaystyle \frac{16}{4}$
[Fraction] Divide: $\displaystyle 4$
