Percent error in Keiko's estimate is 6.25%
What is percent error?Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.
[tex]Percent error=\frac{|observed value -true value|}{true value}*100[/tex]
Students estimate the distance a toy car will role down a ramp.
The car rolls 80cm.
Keiko estimate for the distance the car will role is 85cm.
Percent error in Keiko's estimate is calculated by,

The theoretical probability of swimming, P(swimming), is 12 over 28, but the experimental probability is one half.
The theoretical probability of swimming, P(swimming), is 28 over 40, but the experimental probability is one half.
Answer:
The true statement on the profitability is c.
Step-by-step explanation:
The theoretical profitability of the swimming, P(swimming), is one-half, but the experimental probability is 23 over 50.
The theoretical probability of an occurrence indicates the propensity to occur. The theoretical probability of receiving heads is 1/2 since we know that flipping a coin has an equal chance of landing tails or heads. The frequency of an event actually occurring in an experiment is referred to as its experimental probability.
The theoretical probability of swimming is 1 / 2 because it is either heads or tails. However, the experimental probability of swimming is:
so,
= Number of swimmers / Total number of students
= 23 / 50

The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40. The correct statement is option B.
The theoretical probability of an event is the probability calculated based on the assumption of equally likely outcomes, while the experimental probability is the probability determined from actual data or outcomes observed in an experiment.
In this case, there are 40 students, and each camper flips a coin to decide between swimming and hiking. The outcome frequency shows that 12 students chose swimming, and 28 students chose hiking.
Let's compare the theoretical and experimental probabilities of swimming:
The theoretical probability of swimming, P(swimming), is one-half (1/2), as there are two equally likely outcomes (heads or tails) when flipping a fair coin.
The experimental probability of swimming is the number of students who chose swimming (12) divided by the total number of students (40), which is 12/40.
Now, let's analyze the options:
A. The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 28 over 40.
The theoretical probability is correct (1/2), but the experimental probability is incorrect (it should be 12/40, not 28/40).
B. The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40.
This statement correctly represents both the theoretical probability (1/2) and the experimental probability (12/40).
C. The theoretical probability of swimming, P(swimming), is 12 over 28, but the experimental probability is one half.
This statement has incorrect values for both the theoretical and experimental probabilities.
D. The theoretical probability of swimming, P(swimming), is 28 over 40, but the experimental probability is one half.
The theoretical probability mentioned here (28/40) is not correct. The theoretical probability of swimming is 1/2 (one-half), not 28/40.
The correct statement is option B:
The theoretical probability of swimming, P(swimming), is one half, but the experimental probability is 12 over 40.

Based on her credit score, she qualifies for a fixed rate 30-year mortgage with a 5% APR. Calculate her monthly payment, the amount of her first monthly payment that is an interest payment, the amount that is applied to the principal, and the new loan balance.
i have the answers i just need help on explaining how i got there, i’ve been working on it for over than 2hrs and can’t find it, please help
Arianne's monthly mortgage payment will be $536.82.
What is the monthly payment of Arianne?A mortgage payment is generally made up of components like principal, interest, taxes and insurance. The interest is the cost of borrowing money. The amount of interest one pay is determined by your interest rate and your loan balance.
To calculate Arianne's monthly mortgage payment, we can use the following formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
First, we need to calculate the monthly interest rate: i = APR / 12 = 5% / 12 = 0.004167
Next, we can substitute the values into the formula: The computation of our monthly payment goes as follows:
= $90,000 [ 0.004167(1 + 0.004167)^360 ] / [ (1 + 0.004167)^360 – 1 ]
= $536.82.

In Harold’s class, there are 7 boys for every 6 girls. Identify three equivalent ratios to compare boys to girls.
100 points
Answer:
One equivalent ratio that compares the number of boys to the number of girls in Harold's class is 7:6. Another equivalent ratio is 14:12, and yet another equivalent ratio is 21:18. These ratios are equivalent because they represent the same relationship between the number of boys and girls, just with different scale.
Answer:
14:12
21:18
35:30
Step-by-step explanation:
An equivalent ratio is a ratio that represents the same comparison as another ratio, but with different values. To find equivalent ratios to compare boys to girls in Harold's class, we can multiply or divide both the numerator and denominator of the original ratio by the same value.
The original ratio of boys to girls is 7 boys to 6 girls, or 7:6. Here are three equivalent ratios:
14:12 (multiplying both the numerator and denominator by 2)
21:18 (multiplying both the numerator and denominator by 3)
35:30 (multiplying both the numerator and denominator by 5)
find the probability of three or fewer heads on four flips of a fair coin. enter the answer to four decimal places.
The probability of getting three or fewer heads on four flips of a fair coin is 0.75.
The fair coin is flipped four times. The sample space can be found as follows,
There will be 4 trial and each trial can have two outcomes so the total number of outcomes is 2x2x2x2.
Total possible outcomes are 16.
Now, the number of favorable outcomes when there will be 3 or less heads will be 6 because there has to be 3 heads in four position and that too without repetition.
So, the probability of event is,
P = Total favorable event/Total possible events
P(of three or fewer heads on four flips of a fair coin) = 6/8
So, probability of three or fewer heads on four flips of a fair coin is 0.75.

What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
The two sides are perpendicular = 9.2 and the base is 7.2. The angle ∠A will be calculated as:-
tan(A) = P / B
A = tan⁻¹ ( 9.2 / 7.2 )
A = 53.13°

Joselyn ran 2 miles north, 10 miles east, 4 miles north, 4 miles east and 2 mile north. How far is joselyn from where she started? Leave the answer in simplified radical form.
The distance of 2√65 miles Joselyn is from where she started.
What is the distance between two points?The formula of the distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².
Her initial position is the origin (0, 0), and she ran 2 miles north to reach (0, 2). Then, she ran 10 miles east to reach (10, 2). After that, she ran 4 miles north to reach (10, 6). Then, she ran 4 miles east to reach (14, 6). Finally, she ran 2 miles north to reach (14, 8).
To find the magnitude of Joselyn's displacement, we can use the Pythagorean theorem.
We can consider the displacement from the starting point to Joselyn's final position as the hypotenuse of a right triangle, and the north-south and east-west displacements as the two shorter sides.
Thus, the displacement (d) can be calculated as:
d = √((14 - 0)² + (8 - 0)²)
d = √(14² + 8²)
d = √(196 + 64)
d = √(260)

The number of miles driven is 150
How to determine the number of milesFrom the question, we have the following parameters that can be used in our computation:
Base fee = $15.99
Additional charge = $0.90
Using the above as a guide, we have the following:
Total charge = Base fee + Additional charge * Number of miles
Substitute the known values in the above equation, so, we have the following representation
15.99 + 0.9 * Number of miles = 150.99
Evaluate the like terms
0.9 * Number of miles = 135

You have 2 different savings accounts. For Account A, the simple interest earned after 21 months is $9. 45. For ulo, l le interest rate is 3. 6% for Account A and 2. 4% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer
The principal for Account A is $150, and we do not have enough information to find the principal for Account B. Account A earned the most interest the first month because it has a higher monthly interest rate.
About interest ratesThe principal for Account A can be found using the formula for simple interest:
I = Prt, where I is the interest, P is the principal, r is the interest rate, and t is the time in years.
Rearranging the formula to solve for P, we get P = I / (rt).
For Account A, the interest is $9.45, the interest rate is 3.6%, or 0.036, and the time is 21 months, or 1.75 years.
Plugging these values into the formula, we get:
P = $9.45 / (0.036 × 1.75) = $150
So the principal for Account A is $150.
For Account B, we do not have enough information to find the principal. We know the interest rate, but we do not know the interest or the time.
To determine which account earned the most interest the first month, we can compare the monthly interest rates.
The monthly interest rate for Account A is 3.6% / 12 = 0.3%, and the monthly interest rate for Account B is 2.4% / 12 = 0.2%.
Since the monthly interest rate for Account A is higher, it earned the most interest the first month.

a{100} = 35 - 495
a{100} = - 460
Therefore, the nth term of the sequence is a{n} = 35 + (-5)(n - 1) and the 100th term would be a{100} = - 460.

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $4.20
Step-by-step explanation:
The bag contains $4.20. We know that 18% of the coins are pennies and 36% are dimes. There are 50 coins total, so 18% of 50 is 9 pennies and 36% of 50 is 18 dimes. Since there are 2 more nickels than pennies, there must be 11 nickels. 9 pennies plus 11 nickels plus 18 dimes equals 38 coins. To calculate the total amount of money, we multiply 38 by the value of each type of coin: 9 pennies x $0.01 = $0.09, 11 nickels x $0.05 = $0.55, and 18 dimes x $0.10 = $1.80. Adding these together, we get $0.09 + $0.55 + $1.80 = $2.44. Therefore, the bag contains $4.20.
Answer: There are 9 pennies, 18 dimes, and 11 nickels and 12 quarters
so in total, the bag has $11.2
Step-by-step explanation:
18% of 50 = 9
36% of 50 = 18

What is fraction?A fraction is a mathematical expression that represents a part of a whole. It is written as a ratio of two numbers, the numerator and the denominator, separated by a horizontal line. The numerator represents the part of the whole that is being considered, while the denominator represents the whole.
Given by the question.
To convert 0.5 ft per day to inches per hour, we can use the following conversion factors:
1 ft = 12 inches (since there are 12 inches in a foot)
1 day = 24 hours (since there are 24 hours in a day)
So, to convert 0.5 ft per day to inches per hour, we can use the following steps: Convert feet to inches:
0.5 ft x 12 inches/ft = 6 inches
Convert days to hours:
1 day = 24 hours, so:
6 inches/24 hours = 0.25 inches per hour
