If Idil drove 12 miles in 1/5an hour on average, then she drove at an average speed of 60 miles per hour.
To calculate the average speed of Idil's car in miles per hour, we need to divide the distance she drove (12 miles) by the time it took her to drive that distance (1/5 hour):
Average speed = distance ÷ time
Average speed = 12 miles ÷ (1/5) hour
To divide by a fraction, we can multiply by its reciprocal, so:
Average speed = 12 miles × 5/1 hour
Average speed = 60 miles per hour
Therefore, Idil drove at an average speed of 60 miles per hour.

Find Compund Interest of P = ₹4000, N = 3 years, R = 5 p. C. P. A
The compound interest on ₹4000 at a rate of 5% p.a. for 3 years is ₹631.03.
The formula to calculate compound interest is:
[tex]A= P(1+\frac{R}{N} )^{nt}[/tex]
Where:
A = Final amount (including interest)
P = Principal amount
r = Annual interest rate (as a decimal)
n = Number of times the interest is compounded per year
t = Number of years
In this case, P = ₹4000, N = 3 years, R = 5% per annum (p.a.), which means r = 0.05 and n = 1 (compounded annually).
So, plugging in the values in the formula:
[tex]A= 4000(1+\frac{0.05}{1} )^{1*3}[/tex]
[tex]A= 4000(1.05)^{3}[/tex]
[tex]A = 4631.03[/tex] (rounded to 2 decimal places)
Compound interest is a type of interest that is calculated not only on the initial amount of money borrowed or invested but also on the accumulated interest from previous periods. In other words, the interest earned in each period is added to the principal amount, and the new total becomes the basis for calculating interest in the next period.
This compounding effect can result in significant growth in the value of an investment or debt over time, especially if the interest rate is high and the period of investment or debt repayment is long. For example, if you invest $1,000 at an annual interest rate of 5% compounded annually, you will earn $50 in interest at the end of the first year, and your new total will be $1,050.

Q.4. A shopkeeper bought 18 sets of kurthas at the rate of Rs.1000 each. If 3 sets of kurthas were damaged and the remaining sets of kurthas were sold at the rate of Rs. 1250. Find the profit or loss of the shopkeeper.
Answer:
Rs 750
Step-by-step explanation:
Given, No. of kurtas: 18, Each with CP = Rs 1000.
So, SP of 18 kurtas: 18*1000 = Rs. 18000
Also, 3 sets of kurtas were damaged.
Therefore, Remaining kurtas: 18-3 = 15. SP of each: Rs 1250.
SP of 15 kurtas: 15*1250 = Rs. 18750
So, Clearly SP>CP, Profit.
We know Profit= SP-CP
= 18750-18000 = Rs 750

Expressions can be evaluated by swapping the variables with their values and performing the arithmetic operations in the order specified. If x = 2, for example, the formula "3x + 5" equals 3(2) + 5 = 11. Expressions are commonly used in mathematics to describe real-world situations, construct equations, and simplify complicated mathematical topics.
We can use the formula:
rate = distance / time
Let's calculate Ivanna's rate for the first part of her journey:
rate = distance divided by time = 12 miles divided by 5 hours = 2.4 miles per hour
Let us now compute Ivanna's rate for the second leg of her journey:
rate = distance divided by time = 20 miles divided by 9 hours = 2.222... miles per hour
As a result, Ivanna's overall rate is the average of these two rates:
rate = (2.4 miles per hour + 2.222... miles per hour) / 2 = 2.311... miles per hour
As a result, Ivanna's average speed is approximately 2.311 miles per hour.

a. In the sample:i. The average value of birth weight for all mothers is 7.17 pounds.
ii. For mothers who smoke is 6.82 pounds.
iii. For mothers who do not smoke is 7.28 pounds.b. i. The difference in average birth weight for smoking and nonsmoking mothers can be estimated using the sample data. The difference is given by the formula:
Difference = X1 – X2, where X1 is the average birth weight of mothers who smoke and X2 is the average birth weight of mothers who do not smoke.Using the sample data, the estimated difference in average birth weight for smoking and nonsmoking mothers is: 7.28 – 6.82 = 0.46 pounds.ii. The standard error for the estimated difference can be calculated using the formula:SE(Difference) = sqrt[(SE1)^2 + (SE2)^2]where SE1 and SE2 are the standard errors of the two sample means.Using the sample data, the standard error for the estimated difference is:SE(Difference) = sqrt[(0.23)^2 + (0.12)^2] = 0.26 pounds.iii. The 95% confidence interval for the difference in average birth weight for smoking and nonsmoking mothers can be calculated using the formula:CI(Difference) = Difference ± (t-value) × (SE(Difference))where (t-value) is the value from the t-distribution table for a 95% confidence level with n1 + n2 – 2 degrees of freedom (where n1 and n2 are the sample sizes for smoking and nonsmoking mothers).Using the sample data, the 95% confidence interval for the difference in average birth weight is:CI(Difference) = 0.46 ± (2.048) × (0.26) = (0.04, 0.88) pounds.

A particular concentration of a chemical found in polluted water has been found to be lethal to 20% of the fish that are exposed to the concentration for 24 hours. Twenty fish are placed in a tank containing this concentration of chemical in water. Therefore
a. The probability that exactly 14 fish survive is 0.263b. The probability that at least 10 fish survive is 0.983How do we calculate the probability?a) Probability that exactly 14 fish survive, Let x be the number of fish that survive. Using Binomial distribution, we have:[tex]P(X = x) = C(n,x) * p^x * (1-p)^{(n-x)}[/tex] where n is the total number of fish, p is the probability of survival and C(n,x) is the binomial coefficient. We have n = 20, p = 0.8 (since 20% die) and x = 14. [tex]C(20,14) * (0.8)^14 * (0.2)^6 = 38760 * 0.000016777216 * 0.0264241152 = 0.263[/tex] Therefore, the probability that exactly 14 fish survive is 0.263
b) Probability that at least 10 fish survive To find this probability, we can find the probability that 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 fish die, and subtract this probability from 1. Using the same formula as in (a), we have: [tex]P(X <= 9) = \sum C(n,x) * p^x * (1-p)^{(n-x)}[/tex] where n = 20, p = 0.8 and x varies from 0 to 9. Using a calculator or software, we find:P(X <= 9) = 0.0169Therefore,P(X >= 10) = 1 - P(X <= 9) = 1 - 0.0169 = 0.983 Therefore, the probability that at least 10 fish survive is 0.983.

sam made fruit punch for a party. he mixed 3 gallons of orange juice, 2 quarts of pineapple juice, 4 pints of cranberry juice, and 6 cups of apple juice. how many quarts did he make in all? (2 points) a 14 b fifteen and one half c seventeen and one half d 20
The answer is c): 17 and one-half quarts
To answer the question, we need to find the total amount of juice Sam made by adding the given quantities. However, the given quantities are in different units, which makes the addition difficult. Therefore, we need to convert all quantities to the same unit before adding them.
1 gallon = 4 quarts (since 1 gallon is equal to 128 ounces, and 1 quart is equal to 32 ounces,
thus 1 gallon = 128/32 = 4 quarts)
1 quart = 2 pints
1 pint = 2 cups
Therefore, 3 gallons = 3 x 4 = 12 quarts
2 quarts = 2 x 1 = 2 quarts
4 pints = 4 / 2 = 2 quarts
6 cups = 6 / 4 = 1.5 quarts
Now, we can add all the quantities in quarts to get the total amount of juice that Sam made:
12 + 2 + 2 + 1.5 = 17.5 quarts
Therefore, Sam made 17 and one-half quarts in all. Thus, the correct option is (c) seventeen and one half.

Draw a shape with fractional side lengths. Describe how you will find its area.
Therefore, the area of the rectangle is 6 7/8 square inches.
What is area?Area is a measurement of the amount of space inside a 2-dimensional shape, such as a rectangle, triangle, circle, or any other polygon. It is usually measured in square units, such as square inches, square feet, square meters, etc. The formula for finding the area of a shape depends on the type of shape. For example, the area of a rectangle is calculated by multiplying its length by its width, while the area of a circle is calculated by multiplying the square of its radius by pi (3.14).
Here,
Here's how to draw a shape with fractional side lengths and find its area:
Draw a rectangle with side lengths of 2 1/2 inches and 3 3/4 inches.
Divide the rectangle into smaller squares or rectangles to make it easier to calculate the area.
For example, you can divide the rectangle into two smaller rectangles with side lengths of 2 1/2 inches and 1 3/4 inches, and 2 1/2 inches and 2 inches respectively.
Calculate the area of each smaller rectangle by multiplying the length by the width.
The total area of the rectangle is the sum of the areas of the smaller rectangles.
So the area of the rectangle would be:
Area = (2 1/2 inches x 1 3/4 inches) + (2 1/2 inches x 2 inches)
Area = (5/2 inches x 7/4 inches) + (5/2 inches x 2 inches)
Area = (35/8 square inches) + (10/4 square inches)
Area = (35/8 square inches) + (20/8 square inches)
Area = (55/8 square inches)

school to Roxanne's house. Before dinner, she bicycles home on a bike path that goes straight
from Roxanne's house to her own house. How far does Lisa bicycle each day? If necessary, round to the nearest tenth.
The total distance travelled by Lisa in a day is found to be 10.24 miles.
Explain about the Pythagorean theorem?Pythagoras (born 570 BC) developed a theorem known as the Pythagorean Theorem, which is exclusively applicable to right triangles.
According to the Pythagorean Theorem, a right triangle's hypotenuse square is equal to the sum of its other two sides. The side opposite the right angle is known as the hypotenuse.
Pythagoras theorem:
a² + b² = c²
Given case:
Roxanne's house is 3 miles south of Lisa's school say 'a', which is 3 miles west of Lisa's home say 'b'. Lisa commutes to school by bicycle each day from her home. She rides her bicycle to Roxanne's house after school. She rides her bicycle home before dinner along a bike route that connects Roxanne's home to her own.Here,
a = b = 3 units
Put the values;
3² + 3² = c²
2*9 = c²
c = 3√2
c = 4.24
Total distance = 4.24+ 3 + 3
Total distance = 10.24 miles
Thus, the total distance travelled by Lisa in a day is found to be 10.24 miles.

PLEASE HELP... In each right triangle, find the missing side length to the nearest tenth.
The side length x of the right angle triangle is 25 units.
How to find the sides of a right triangle?A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.
The sides of a right triangle can be found using Pythagoras's theorem. Let's use Pythagoras's theorem to find the side x.
Hence,
c² = a² + b²
where
c = hypotenuse sidea and b are the other legsTherefore,
a = 24 units
b = 7 units
Hence,
24² + 7² = x²
576 + 49 = x²
625 = x²
square root both sides of the equation
x = √625
x = 25 units
Therefore,
x = 25 units

A function is graphed on the coordinate grid. Possible inputs for the quadratic when the output is 3 are ___ or ___.
Step-by-step explanation:
This graph shows a quadratic curve with roots 0 and -4
The polynomial is therefore
x² -x(α+β) + αβ
x² -x(0-4) + 0(-4)
x² +4x +0
x² + 4x
But it's an n-shaped curve, meaning a is negative
Multiply through by -1
-x² - 4x
y = -x² - 4x
So when the input value y = 3, we have
3 = -x² - 4x
Rearrange
x² + 4x + 3 = 0
Factorize
x² + 3x + x + 3 = 0
x(x + 3) +1(x + 3) = 0
(x + 1) (x + 3) = 0
x + 1 = 0 and x + 3 = 0
x = 0-1 and x = 0-3
Therefore,
x = -1 and -3

Using the inverse transform method for discrete distribution, define a process for generating random variates from a binomial distribution with N 6 and p 0.4. (sixth decimal place.)
The another random variate from a binomial distribution with n=6 and p=0.4 has been generated as X=3.
The process of generating random variates from a binomial distribution using the inverse transform method for discrete distribution is done as follows:Step 1: Determine the probability mass function (pmf) of the binomial distribution with parameters n and p. For example, for a binomial distribution with n = 6 and p = 0.4, the pmf is given by:P(X=k) = (6 choose k)(0.4)^k(1-0.4)^(6-k), where k=0,1,2,3,4,5,6Step 2: Calculate the cumulative distribution function (CDF) of the binomial distribution by summing the pmf up to each value of k. The CDF is given by:F(k) = P(X ≤ k) = ΣP(X=i) for i=0 to k, where k=0,1,2,3,4,5,6Step 3: Generate a uniform random variate, U, between 0 and 1. For example, U=0.23456.Step 4: Find the smallest value of k such that F(k) ≥ U. This value of k is the random variate X. For example, if U=0.23456, then F(0)=0.10737, F(1)=0.38223, and F(2)=0.74304. Since F(1) is the smallest value of F(k) that is greater than or equal to U, X=1. Therefore, a random variate from a binomial distribution with n=6 and p=0.4 has been generated as X=1.To find another random variate from the same distribution, repeat steps 3 and 4. For example, U=0.987654, F(0)=0.10737, F(1)=0.38223, F(2)=0.74304, F(3)=0.91892, F(4)=0.98544, and F(5)=0.99856. Since F(3) is the smallest value of F(k) that is greater than or equal to U, X=3. Therefore, another random variate from a binomial distribution with n=6 and p=0.4 has been generated as X=3.
