Find Maya's finance charge for September using the previous balance method, the adjusted balance method, and the
daily balance method. Among those three possible finance charges, what is the value of the one which is neither lowest
nor highest?
a $3.79
b. $3.90
C. $3.68
d. $4.45
Answer:
C. $3.68
Step-by-step explanation:
I took the test
Based on the three possible finance charges, the value of the one that is neither lowest nor highest is $3.68.
What is a finance charge?A finance charge is regarded as the cost incurred when a person borrows money and it often includes interest and other fees.
To find the finance charges, the formula is:
= Amount transacted x Interest rate / 12 months
395.61 x [tex]\frac{11.84}{100}[/tex] / 12
= 3.68
Therefore the correct option is option c.

12. The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 253.4 and a standard
deviation of 62.3. (All units are 1000 cellsfuL) Using the empirical rule, find each approximate percentage below.
a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or
between 191.1 and 315.7?
b. What is the approximate percentage of women with platelet counts between 128.8 and 378.0?
a. Approximately
% of women in this group have platelet counts within 1 standard deviation of the mean,
or between 191.1 and 315.7.
(Type an integer or a decimal. Do not round.)
b. Approximately
% of women in this group have platelet counts between 128.8 and 378.0.
(Type an integer or a decimal. Do not round.)
Answer:
a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or
between 191.1 and 315.7?
68%
b. What is the approximate percentage of women with platelet counts between 128.8 and 378.0?
95%
Step-by-step explanation:
The Empirical rule formula states that:
1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or
between 191.1 and 315.7?
μ = mean = 253.4
σ = standard deviation = 62.3.
μ - σ
= 253.4 - 62.3
= 191.1
μ + σ
= 253.4 + 62.3
= 315.7
Therefore, the first empirical rule holds for Question a. This states that 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
Therefore, the approximate percentage of women with platelet counts between 191.1 and 315.7 is 68%
b. What is the approximate percentage of women with platelet counts between 128.8 and 378.0?
μ = mean = 253.4
σ = standard deviation = 62.3.
Applying the second rule of the empirical rule: this states that: 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
For x = 128.8
μ - 2σ
= 253.4 - 2 × 62.3
= 128.8
μ + 2σ
= 253.4 + 2 × 62.3
= 378
Therefore, the approximate percentage of women with platelet counts between 128.8 and 378.0 is 95%

If 1/6x + 3 = 7 what is x
Answer:
x = 24
Step-by-step explanation:
1/6 x + 3 = 7
1/6 x = 4
x = 24
Step-by-step explanation:
The expression is 1/6x+3=7
1/6x+3=7
First, you subtract 3 from both sides
1/6x=4
Then you divide 1/6 from both sides
Dividing fractions is confusing, so I will show you how to do it
4/1 / 1/6
Because you can't divide 1 by 6, you KCF, or keep change flip.
You keep the 4/1, you change the operation to multiplication, and flip 1/6 to make it 6/1.
Now the problem is 4x6=24
So x=24

Tyler wants to use $300 he has saved to buy a new guitar and join a music club. The guitar costs $140. The music club has a $25 membership fee, and for $11.95 per month, members can download 30 songs. Tyler can afford the music club membership for____ months, after which he will have_____ left.
Answer:
11 months ; $3.55
Step-by-step explanation:
Amount saved = $300
Cost of guitar = $140
Membership fee = $25
Monthly fee = $11.95
For how manyonths can Tyler afford the membership :
The one time fee = (membership fee + cost of guitar)
= $140 + $25 = $165
Amount left = $300 - $165
Amount left = $135
Number of monthly fee the balance can afford :
Amount left / monthly fee
= $135 / $11.95
= 11.29
Hence, the number of months he can pay for is 11 months
Amount left = $135 - ($11.95 * 11 months)
$135 - $131.45
= $3.55

Factor x^2 + 9x = -20
Answer:
(x +5) (x +4) = 0
Step-by-step explanation:
x^2 + 9x +20 = 0
x^2 + 4x + 5x +20 = 0
x(x + 4) + 5(x + 4) = 0
(x +5) (x +4) = 0
Answer:
see below
Step-by-step explanation:
x^2 + 9x = -20
x^2 + 9x + 20 = 0
factor the expression
(x + a)(x + b)
a + b = 9
a = 4
b = 5
ab = 20
rewrite the factor expression:
(x + 4) (x + 5)
x + 4 = 0 and x + 5 = 0
therefore,
x = -4
x = -5
The value of coins in the pockets of several students is recorded. What is the mean of the values: 10, 20, 35, 35, 35, 40, 45, 45, 50, 60. A. 10 cents B. 35 cents C. 37.5 cents D. 50 cents
Answer:
C. 37.5
Step-by-step explanation:
10 10 + 20 + 35 + 35 + 35 + 40 + 45 + 45 + 60 + 50=375
375÷10=37.5
The mean of the given data set 10, 20, 35, 35, 35, 40, 45, 45, 50, 60 is 37.5 so option (C) will be correct.
What is mean?The mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.
In other words, the mean is the foundation of the deviation of data from all data sets.
Mean = sum of data / Number of data
For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be
( 40 + 45+ 44 + 46 + 48) /5 = 44.6.
Given the data set,
10, 20, 35, 35, 35, 40, 45, 45, 50, 60
Now mean is given as
Mean = sum of data / Number of data
So,
Mean = (10+20+35+35+35+40+45+45+50+60)/10
Mean = 37.5
Hence "The mean of the given data set 10, 20, 35, 35, 35, 40, 45, 45, 50, 60 is 37.5".

6(5 - 2v) = 4(-3v - 1)
Answer:
30=-4
Step-by-step explanation:
Simplifying
6(5 + -2v) = -4(3v + 1)
(5 * 6 + -2v * 6) = -4(3v + 1)
(30 + -12v) = -4(3v + 1)
Reorder the terms:
30 + -12v = -4(1 + 3v)
30 + -12v = (1 * -4 + 3v * -4)
30 + -12v = (-4 + -12v)
Add '12v' to each side of the equation.
30 + -12v + 12v = -4 + -12v + 12v
Combine like terms: -12v + 12v = 0
30 + 0 = -4 + -12v + 12v
30 = -4 + -12v + 12v
Combine like terms: -12v + 12v = 0
30 = -4 + 0
30 = -4
