Doug bought a new car for $25,000. He estimates his car will depreciate, or lose value, at a rate of 20% per year. The value of his car is modeled by the equation V = P(1 – r)t, where V is the value of the car, P is the price he paid, r is the annual rate of depreciation, and t is the number of years he has owned the car. According to the model, what will be the approximate value of his car after 4 and one-half years?
9514 1404 393
Answer:
$9,159
Step-by-step explanation:
Put the given numbers into the formula and do the arithmetic.
V = $25,000(1 -0.20)^4.5 ≈ $9,159
The value of the car will be about $9,159 after 4 1/2 years.

eric invested 5000 dollars in the stock market. The value of his stock increased by 13%. a) what is the amount earned from this investment?
b) what is the new value of the stock?
Answer:
[tex]Earnings = 650[/tex]
[tex]New\ Value = 5650[/tex]
Step-by-step explanation:
Given
[tex]Amount = 5000[/tex]
[tex]Rate = 13\%[/tex]
Solving (a): The earnings.
This is calculated as:
[tex]Earnings = Amount * Rate[/tex]
[tex]Earnings = 5000 * 13\%[/tex]
[tex]Earnings = 650[/tex]
Solving (b): New Value
This is calculated as:
So, we have:
[tex]New\ Value = Amount + Earnings[/tex]
[tex]New\ Value = 5000 + 650[/tex]
[tex]New\ Value = 5650[/tex]

Use the following probabilities to answer the question. It may be helpful to sketch a Venn diagram.
P(A) = 0.44, P(B) = 0.36 and P(A and B) = 0.20 .
P(B ∣ not A)=
Answer:
0.2857
Step-by-step explanation:
P(B | not A)
Recall :
P(A | B) = P(A n B) / P(B)
Hence ;
P(B | not A) = P(B and not A) / P(not A)
P(not A) = 1 - P(A) = 1 - 0.44 = 0.56
P(B and not A) = P(B) - P(A and B) = 0.36 - 0.20 = 0.16
Hence,
P(B | not A) =P(B and not A) / P(not A) = 0.16 / 0.56
= 0.2857
A particular fruit's weights are normally distributed, with a mean of 406 grams and a standard deviation of 9 grams.
If you pick one fruit at random, what is the probability that it will weigh between 379 grams and 394 grams
Answer:
P(379<X<394) = 0.0899 = 8.99%
Step-by-step explanation:
P(379<X<394) = normalcdf(379,394,406,9) = 0.0898613146 ≅ 8.99%
Therefore, if you pick one fruit at random, the probability that it will weigh between 379 grams and 394 grams is 0.0899 or about an 8.99% chance of occurence.
What is the y-intercept in the equation y = 4x - 3?
answer: -3
remember the equation y = mx + b
m is the slope, and b is the y-intercept
so in the equation y = 4x - 3,
4 replaces the m as the slope and -3 replaces b for the y-intercept
so -3 is your answer
Answer:
-3

Jennifer age 18 initially invested $1000 at 8% interest how old would she be when the account is $128,000
Answer:
2,304 years old
Step-by-step explanation:
Given: Jennifer age = 18, Invested = $1000 at 8% interest
To find: How old would she be when the account is $128,000?
Wrong solution
Solution: To figure out how old she will be when her account is $128,000, simply find the difference between her current account value by her current age, by dividing. Then multiply the result by the future account value.
Step 1: [tex]\frac{1000}{18} = 55.5555555556[/tex]
Rounding, that is; 55.56
Step 2: Now, multiply the result by the future account value.
[tex]55.56[/tex] × [tex]128000 = 7111680[/tex]
Correct solution
Solution: To find out how old she will be when her account is $128,000, set up a fraction;
[tex]\frac{1000}{8} = \frac{12800}{x}[/tex]
Step 1: Divide the numbers
[tex]\frac{1000}{8} = \frac{128000}{x} \\\\\frac{500}{9} = \frac{128000}{x}[/tex]
Step 2: Multiply all terms by the same value to eliminate fraction denominators
[tex]\frac{500}{9} = \frac{128000}{x} \\\\x * \frac{500}{9} = x * \frac{128000}{x}[/tex]
Step 3: Cancel multiplied terms that are in the denominator
[tex]x *\frac{500}{9} = x * \frac{128000}{x} \\\\x * \frac{500}{9} = 128000[/tex]
Step 4: Re-order terms so constants are on the left
[tex]x * \frac{500}{9} = 128000\\\\\frac{500}{9} x= 128000[/tex]
Step 5: Combine multiplied terms into a single fraction
[tex]\frac{500}{9} x = 128000\\\\\frac{500x}{9} = 128000[/tex]
Step 6: Multiply all terms by the same value to eliminate fraction denominators
[tex]\frac{500x}{9} = 128000\\\\9 * \frac{500x}{9} = 9 * 128000[/tex]
Step 7: Cancel multiplied terms that are in the denominator
[tex]9 * \frac{500x}{9} = 9 * 128000\\500

What is the 12th term of the geometric sequence where *
A7 = 7 and 10 = -56
O-448
0-224
O -112
0 -96
Answer:
-224
Step-by-step explanation:
Geometric sequence is given by An = A*R^(n-1)
Given A7 = 7 and A10 = -56
A10/A7 = -8 = R^(10-7)
R^3 = -8
R = -2
A12 = A10*R^2
= -56*-2^2
= -224
Answer:
Step-by-step explanation:
A7 = 7
A10 = -56
7xRxRxR = -56
R = -2
A12 = A10xRxR
= -56 x -2 x -2
= 224

Find the equation of a line perpendicular to 4x - 5y = -1 that contains the point (5, -4)
Answer:
y = -5/4x + 2 1/4
Step-by-step explanation:
you would start by changing the equation to point intercept form
4x + 1 = 5y
4/5y + 1/5 = y
then you fill in the points and change the slope to -5/4 (reciprocal and opposite sign)
-4 = -5/4(5) + b
-4 = -6.25 + b
2.25 = b
a 440m long road is being repaired at the end of 3 days the workers had repaired 3/4 of the road what length of the road is left unrepaired
THE ANSWER IS 110 m
Workers had repaired 3/4 of the road
it means3/4×440 is been repaired
length of repaired road is 3×110 = 330m
length of unrepaired road = Length of to road - length of repaired road
i.e. = 440-330 = 110m

A family dines in a popular franchise restaurant. At the end of the meal, they decide to leave their server a monetary tip that is equal to 20% of the total bill amount, $60.50. How much will the family leave their server as a tip?
A family dines in a popular franchise restaurant. They plan to use a coupon that will give them a discount of 15% off of their total dinner bill, not including applicable sales tax or their server’s tip. If the family’s dinner bill totaled $34.00 before tax and tip, how much money will they save by using the coupon?
A family dines in a popular franchise restaurant. They plan to use a coupon that will give them a discount of 10% off of their total dinner bill, not including applicable sales tax or their server’s tip. The bill totals $157.30 before tax and tip. What is the new total after the server applies the 10% off coupon?
A family of eight dines in a popular franchise restaurant. The restaurant has a policy of automatically including a standard tip to the final bill for parties larger than six people. The bill for the meal included a total of $58.25 in food and beverage sales, plus a standard tip of $10.49. What percent of the food and beverage sales does the restaurant consider to be a standard tip for parties larger than six?
A family dines in a popular franchise restaurant that has a policy of automatically including a 20% tip on all food and beverage sales before coupon discounts are applied. What is the family’s total bill amount if their food and beverages totaled $94.20 and they used a 15% off coupon? (HINT: Create more than one model.) DONT ANSWER THE QUESTION JUST PUT THE EQUATIONS
Answer:
A) t=0.2(60.5)
B) d=0.15(34)
C) t=0.9(157.3)
D) p=100(10.49/58.25)
E) t=0.85(94.2+0.2(94.2))
Step-by-step explanation:
A)
Let the tip be represented by t. The tip is 20% of $60.50:
t=0.2(60.5)
B)
Let the money they save be represented by d. Their discount is 15% of $34:
d=0.15(34)
C)
Let the new total be represented by t. Their discount is 10%, so they will only be paying 90% of $157.30t:
t=0.9(157.3)
D)
Let the percentage be represented by p. The tip is $10.49, to find this as a precent of the $58.25 bill, divide the tip by the bill and multiply by 100:
p=100(10.49/58.25)
E)
First find the total after the tip but before the coupon.
Their tip is 20% of $94.20, and their total before the coupon is $94.20 plus the tip: 94.2+0.2(94.2)
Now find their final total.
Let the final total be represented by t. The discount is 15%, so they will only be paying 85% of the total after tip:
t=0.85(94.2+0.2(94.2))
