When Vondel Bradshaw checked his credit card statement, he found that a sales
slip dated 3/2 for $12.49 was posted as $12.99. He also found that a purchase
for $56.29 dated 2/19 was unauthorized. If the new balance on the statement
was $491.23, what is the correct new balance?
Answer: $548.02
Step-by-step explanation:
Correct for inaccurate postings...
add the $0.50 overcharge and the $56.29 unauthorized charge from $491.23
491.23+.50+56.29=548.02
A sample of restaurants in a city showed that the average cost of a glass of iced tea is $1.25 with a a standard
deviation of 7c. Three of the restaurants charge 95¢, 1.00, and $1.35. Determine the z-value for each restaurant.
Answer:
For the restaurant that charges 95 cents, the z-score is -4.29.
For the restaurant that charges $1, the z-score is -3.57.
For the restaurant that charges $1.35, the z-score is 1.43
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average cost of a glass of iced tea is $1.25 with a standard deviation of 7c.
This means that [tex]\mu = 1.25, \sigma = 0.07[/tex]
Restaurant that charges 95 cents:
The z-score is found when X = 0.95. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0.95 - 1.25}{0.07}[/tex]
[tex]Z = -4.29[/tex]
For the restaurant that charges 95 cents, the z-score is -4.29.
Restaurant that charges $1:.
X = 1
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1 - 1.25}{0.07}[/tex]
[tex]Z = -3.57[/tex]
For the restaurant that charges $1, the z-score is -3.57.
Restaurant that charges $1.35:
X = 1.35
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1.35 - 1.25}{0.07}[/tex]
[tex]Z = 1.43[/tex]
For the restaurant that charges $1.35, the z-score is 1.43

“Find the area of the shaded portion. Show all work for full credit.”
Answer:
360°
Step-by-step explanation:
xjjdjdjdjedjejdjej
hypotenuse side = 12
height = √12^2 - 6^2
= √144 - 36
= √108
= 10.39
area of one triangle = 1 / 2 bh
b = base
h = height
area of one triangle = 1 / 2 × 6 × 10.39
area of one triangle = 31.17 unit^2
area of 2 triangle = 2(31.17) = 62.34 unit^2
area of non shaded sector.
area of the sector = 120 / 360 × 3.14 × 6^2
area of the sector = 37.68 units^2
area of the shaded portion = 62.34 - 37.68
= 24.66 unit^2

Answer:
675 in³
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( lis length, b is breadth and h the height )
Here l = 15, b = 5 and h = 9 , then
V = 15 × 5 × 9 = 675 in³

Ahmed invests $4000 in two different accounts. The first account paid 10 %, the second account paid 9% in
interest. At the end of the first year he had earned $370 in interest. How much was in each account?
Answer: 3000$ in 9% account
Step-by-step explanation: sums in accounts are x and (4000-x)
Interests are 0.09x and 0.10(4000-x) = 400-0.1x
Now you get 0.09x -0.1x + 400 = 370
Then -0.01x = -30 and x= 3000

H varies directly as L. If H = 30 when L=60, determine H when L= 40.
a) Write the variation equation.
b) Determine the value of the quantity indicated.
a) Choose the correct answer below.
O A. H=L
k.
O B. L=
H
O C. H=kL
w
k k
OD. H=*
b) H= |(Type an integer or a decimal.)
Answer:
i) The variation equation H = k L
ii) The value of H = 20
iii) C) H = k L
Step-by-step explanation:
Step(i):-
Given that H varies directly as L
H ∝ L
H = k L
Given that H =30 and L = 60
⇒ 30 = k (60)
[tex]k = \frac{30}{60} = \frac{1}{2}[/tex]
Step(ii):-
Given that L = 40
The variation of the equation = H = k L ...(i)
put L = 40 in equation (i)
[tex]H = \frac{1}{2} X 40 = 20[/tex]

Answer:
Surface area of cube = 504.84 cm²
Step-by-step explanation:
Given:
Sum of all sides = 110.4 cm
Find:
Surface area of cube
Computation:
Sum of all sides = Perimeter of cube
Perimeter of cube = 12 x side
12 x side = 110.4
Side = 110.4 / 12
Side = 9.2 cm
Surface area of cube = 6 x Side²
Surface area of cube = 6 x 9.2²
Surface area of cube = 6 x 84.64
Surface area of cube = 504.84 cm²
