Answer:
r = 4.5%
Step-by-step explanation:
Formula:
I = Prt
r = I/(Pt)
Given:
I = 662.29
P = 4205
t = 3.5
Work:
r = I/(Pt)
r = 662.29/(4205 * 3.5)
r = 662.29/14717.5
r = 0.045
r = 4.5%
Clark spent a total of $46 on a pair of shoes and a new jacket. The shoes cost $8 more than the jacket. Write a system of equations to find the cost of the shoes x and the cost of the jacket y. Then find the cost of the shoes.
If total cost of a pair of shoes and jacket is $46 and cost of shoes is $8 more than cost of jacket, cost of shoes is $27 and the system of equations to determine the cost of the shoes are x - y = 8 and x + y = 46.
Let the cost of the shoes be x and the cost of the jacket be y in dollars. As cost of shoes is $8 more than the jacket,
x = y + 8
Therefore, x - y = 8 (1)
Also the total cost of the shoes and jacket is $46, therefore
x + y = 46 (2)
Adding (1) and (2) we get
2x = 54
x = 27
Therefore, cost of shoes is $27.

the equation y = 3x – 6 and the table shown describe two different linear functions.
Which function has the greatest rate of change? Enter either Equation or Table in the box below. Then, explain.
The function in the equation has a slope of ____ and the function in the table has a slope of ___
Answer:
The slope is 3, the function in the table has a slope of 3.5
Step-by-step explanation:
For the equation, you can just look at the number before x for the slope. For the table, you need to form an equation. (1,5.5) (2,9) are the points that I would use. The equation is y=3.5x-2, the slope is 3.5.
The function in the table has greater rate of change .
Given,
Line equation : y = 3x - 6
Tabular data .
Now,
In line,
y = 3x - 6
Compare it with the standard form of line
y = mx + c
Hence the slope of line is 3 .
Now the slope of table,
m = y2 - y1 /x2 - x1
m = 9 - 5.5 / 2 - 1
m = 3.5
Slope of table is 3.5 .
Thus the table data has greater slope and thus have a greater rate of change than the line .

Lincoln's monthly bank statement showed the following deposits and withdrawals: − −$28. 51, − −$41. 34, $90. 95, − −$88. 95, $11. 16 If Lincoln's balance in the account was $19. 96 at the beginning of the month, what was the account balance at the end of the month?
After considering the deposits and withdrawals, the account balance at the end of the month is $64.23.
To calculate the account balance at the end of the month, we need to add up all the deposits and withdrawals. The negative values represent withdrawals, while the positive values represent deposits.
Starting with an initial balance of $19.96, we can calculate the final balance by adding the amounts of the deposits and subtracting the amounts of the withdrawals.
Starting balance: $19.96
Deposits: $90.95, $11.16
Withdrawals: -$28.51, -$41.34, -$88.95
Adding the deposits: $19.96 + $90.95 + $11.16 = $122.07
Subtracting the withdrawals: $122.07 - $28.51 - $41.34 - $88.95 = $64.23
Therefore, the account balance at the end of the month is $64.23.

Frank Pianki, the manager of an organic yogurt processing plant desires a quality specification with a mean of 16.0 ounces, an upper specification limit of 16.5 ounces, and a lower specification limit of 15.5 ounces. The process has a mean of 16.0 ounces and a standard deviation of 1 ounce. The process capability index (C
pk
)= (round your response to three decimal places).
Answer:
To three decimal places, The process capability index is 0.167
Step-by-step explanation:
We have to find the process capability index,
Upper specification = 16.5 ounces,
Lowe specification = 15.5 ounces
Mean = 16.0 ounces
Standard Deviation = S = 1 ounce
process capability index = (upper specification - lower specification)/6S
process capability index = (16.5 - 15.5)/6(1)
= 1/6
Process capability index = 1/6 = 0.16666667
To 3 decimal places, we get,
Process capability index = 0.167

Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.
What is the Alternate Interior Angles Theorem?If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.
What are Angles on a Straight Line?Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.
Given the following:
m∠BFC = 75°
m∠GFC = 38°
∠EFB, ∠BFC, and ∠GFC are angles on a straight line, therefore:
m∠EFB = 180 - m∠BFC - m∠GFC
Plug in the values
m∠EFB = 180 - 75 - 38
m∠EFB = 67°
Find the measure of angle FBC:
Angles FBC and EFB are alternate interior angles, therefore:
m∠FBC = m∠EFB = 67° [alternate interior angles theorem]
m∠FBC = 67°
In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

Element X decays radioactively with a half life of 8 minutes. If there are 450 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 37 grams?
If there are 450 grams of element and half life is 8 minutes, then it will take 28.83 minutes the element to decay to 37 grams
Half life of radio active element = 8 minutes
Initial quantity of radio active element = 450 gram
Final quantity of radio active element = 37 grams
y = a(0.5)^(t/h)
Substitute the values in the equation
37 = 450 (0.5)^(t/8)
Move 37 to left hand side of the equation
37 / 450 = 0.5^(t/8)
Convert the terms to logarithm
t/8 = \(log_{0.5}\frac{37}{450}\)
t/8 = 3.60
t = 8 × 3.60
Multiply the numbers
t = 28.83 minutes
Therefore, the it will take 28.83 minutes to decay to 37 grams

The probability that two independent events both occur is the sum of the probabilities of each independent event. 4. When choosing a card randomly from a deck of cards, choosing a 5 or a spade are not
Answer:
(i) False
(ii) Selecting a 5 or a spade are not independent.
Step-by-step explanation:
(i)
Independent events are those events that occur at the same time, i.e. the occurrence of one event does not effects the occurrence of the other.
If A and B are independent events then: \(P(A\cap B)=P(A)\times P(B)\)
Whereas as if two events are mutually exclusive, then the probability of them both taking place at the same time is 0.
Then for events A and B: \(P(A\cap B)=0\)
Thus, the statement is False.
(ii)
In a standard deck of 52 cards there are:
Spades = 13
Diamond = 13
Heart = 13
Clubs = 13
And each of these 13 cards are:
K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A
If a card labelled as 5 is selected then it could also be a Spade.
And if a spade is selected then the card could be labelled as 5.
So, selecting a 5 or a spade are not independent.

Which system of linear equations has the ordered pair (15, – 25) as its solution?
x - 2y = 35 and 2x + y = 55
x-2y = -35 and 2x - y = 55
2x+y=5 and 2x + y = 55
2x+y=5 and 2x – y=55
Answer:
The solution to the system of equations be:
(x, y) = (15, -25)
Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.
Step-by-step explanation:
Let us solve and check the 4th system of equations
2x+y=5
2x – y=55
solving the system of equations
\(\begin{bmatrix}2x+y=5\\ 2x-y=55\end{bmatrix}\)
subtracting
\(2x-y=55\)
\(-\)
\(\underline{2x+y=5}\)
\(-2y=50\)
so the system of equations becomes
\(\begin{bmatrix}2x+y=5\\ -2y=50\end{bmatrix}\)
solve -2y = 50
\(-2y=50\)
Divide both sides by -2
\(\frac{-2y}{-2}=\frac{50}{-2}\)
\(y=-25\)
\(\mathrm{For\:}2x+y=5\mathrm{\:plug\:in\:}y=-25\)
\(2x-25=5\)
Add 25 to both sides
\(2x-25+25=5+25\)
Simplify
\(2x=30\)
Divide both sides by 2
\(\frac{2x}{2}=\frac{30}{2}\)
simplify
\(x=15\)
Thus, the solution to the system of equations be:
(x, y) = (15, -25)
Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.

An electric blender has a price of $240 after import duty is added to the cost price.What is the cost price of the blender if import duty is 20%?
Answer:
$200
Step-by-step explanation:
Given :
Cost of blender + import duty = $240
Import duty = 20% of cost price
Let :
Cost of blender = x
Import duty = 20% of x = 0.2x
Therefore,
x + 0.2x = $240
1.2x = 240
x = 240 / 1.2
x = $200
