= 37.50%
In 2009, Anna paid $3,060 in federal income tax. In 2010, she paid 70% more than in 2009. How much did Anna pay in 2010?
Answer:
$5,202
Step-by-step explanation:

$2,142 + $3,060 = $5,202
Lincoln purchased a new car in 2010 for $22,800. The value of the car was $14,100 in the year 2012, then what would be the predicted value of the car in the year 2014, to the nearest dollar?
Answer:
872
Step-by-step explanation:
The predicted value of $16,348 for the car in 2014.
What is the depreciation rate?The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.
Given,
The car was purchased for $22,800 in 2010.
The value of the car was $14,100 in 2012.
The time elapsed between 2010 and 2012 is 2 years, so we can calculate the annual depreciation rate as follows:
depreciation rate = (purchase price - value after 2 years) / (purchase price x 2 years)
= (22,800 - 14,100) / (22,800 * 2)
= 0.0798 or 7.98%
This means that the car depreciates by approximately 7.98% of its value per year. To predict the value of the car in 2014, we can use this rate to calculate the value after 4 years (since 2010):
value after 4 years = purchase price x (1 - depreciation rate)⁴
= 22,800 x (1 - 0.0798)⁴
≈ 16,347.97
Rounding this to the nearest dollar gives us a predicted value of $16,348 for the car in 2014.

You estimate that there will be 85 people at your party, but only 75 show up, what is the percent error of your estimate?
Answer:
Percentage error of your estimate = 13%
Step-by-step explanation:
Given
Approximate value = 85
Exact value = 75
To determine
Percentage error can be determined using the formula
Percentage Error = |Approximate Value − Exact Value| / |Exact Value| × 100%
= |85 − 75| / |75| × 100%
= 10 / 75 × 100%
= 0.1333 × 100%
= 13%
Therefore, percentage error of your estimate = 13%

A $65 drone is on sale for $51.35. What is the percent of discount?
Answer:
20% off
Step-by-step explanation:
Answer:
21%
Step-by-step explanation:
To calculate the percentage discount between two prices, follow these steps:
Subtract the post-discount price from the pre-discount price.
Divide this new number by the pre-discount price.
Multiply the resultant number by 100.
$51.35-65=13.65
13.65/65= -0.21
-0.21*100=-21

Omar ordered his sister a birthday card from a company that randomly selects a card from their inventory. The company has 21 total cards in inventory. 14 of those cards are birthday cards. What is P(not a birthday card)
Answer:
P = 7
Step-by-step explanation:
We have 21 total cards and out of those 21 cards, 14 of those are birthday cards. So that means that the amount of cards that are not birthday cards is the number of cards subtracted by the number of birthday cards, also shown as 21 - 14. So 21 - 14 = P, so now we solve what 21 - 14 is which is 7, so that means P = 7.

A basketball coach kept stats for his team in free throw percentage and steals (among others). At the last game, Erin's free throw percentage was 79% and she had 4 steals. The team averaged 87% from the free throw line with a standard deviation of 12 and they averaged 7 steals with a standard deviation of 3. In which category did Erin do better compared with her team
Answer:
Due to the higher z-score, she did better in the free throw category.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this question:
She did better in the category that she had the higher z-score:
Free-throws:
Her free throw percentage was 79%, which means that [tex]X = 79[/tex]
The team averaged 87% from the free throw line with a standard deviation of 12, which means that [tex]\mu = 87, \sigma = 12[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{79 - 87}{12}[/tex]
[tex]Z = -0.67[/tex]
Steals:
She had 4 steals, which means that [tex]X = 4[/tex]
Averaged 7 steals with a standard deviation of 3, which means that [tex]\mu = 7, \sigma = 3[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{4 - 7}{3}[/tex]
[tex]Z = -1[/tex]
Due to the higher z-score, she did better in the free throw category.

A company rents out 15 food booths and 23 game booths at the county fair. The fee for a food booth is
$150 plus $4 per day. The fee for a game booth is $95 plus $10 per day. The fair lasts for d days, and all the
booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the
company is paid.
The expression is
Answer:
290d + 245
Step-by-step explanation:
Hello! So what you do first is make two equations, then combine them.
For the food booths, the equation would be 15(4d) + 150
For the game booths, the equation would be 23(10d) + 95
Now simplify them.
Food booths: 60d + 150
Game booths: 230d + 95
Next, we combine the two equations to get one equation.
60d + 150 + 230d +95
Simplify even more...
290d + 245
This is going to be your equation. I don't know the number of days the fair went so I can't go any futher on this question. Hope this helps though!

Answer:
5 miles
Step-by-step explanation:
It may get a bit messy, but we can solve for the desired value directly. Let d = the distance walked (in miles). Then 20-d is the distance traveled in the car. The relevant relation is ...
time = distance / speed
The total travel time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours. Here is the equation for total travel time.
total time = time spent walking + time spent riding
13/6 = (d/3) + (20-d)/30
Multiplying by 30 gives ...
65 = 10d + 20 -d
45 = 9d . . . . . . . . . . subtract 20
5 = d . . . . . . . . . . . . divide by 9
The girl walked 5 miles.
_____
Check
Her walking time was (5 mi)/(3 mph) = 5/3 h = 1:40.
Her riding time was (15 mi)/(30 mph) = 1/2 h = 0:30.
Her total travel time was 1:40 +0:30 = 1:70 = 2:10, as required.

B) (10, 7)
C) (5, 7) D) (-7,7)
Answer:
A). (1, 7)
Step-by-step explanation:
-3x – 2y = -17
9x + 2y = 23
____________+
6x = 6
x = 6/6
x = 1
9x + 2y = 23
9(1) + 2y = 23
9 + 2y = 23
2y = 23 - 9
2y = 14
y = 14/2
y = 7

NEED THIS ASAP

Answer:
f5= 5
Step-by-step explanation:
The value of F₅ in the given Fibonacci sequence is 5, i.e. option A is the correct answer.
What is the Fibonacci sequence?Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones.
i.e.
[tex]F_n = F_{n-1} + F_{n-2}[/tex]
We have,
Fibonacci sequence {0, 1, 1, 2, 3, 5, 8, ...}
i.e.
F₁ = 0, F₁ = 1, F₂ = 1, F₃ = 2, F₄ = 3, F₅ = 5, F₆ = 8
Now,
We have to find the value of F₅,
Here, for n = 5,
i.e.
[tex]F_5 = F_{5-1} + F_{5-2}[/tex]
i.e.
F₅ = F₄ + F₃
So,
F₅ = 3 + 2
So,
We get,
F₅ = 5
So, the value of F₅ for the given sequence is F₅.
Hence, we can say that the value of F₅ in the given Fibonacci sequence is 5, i.e. option A is the correct answer.
