The percent decrease in the travel time was 60 %.

We will use unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We are given that Korra takes 27 minutes to walk to work. After getting a new job, Korra takes 16.27 minutes to walk to work.

Time taken to walk to home = 27 minutes

Time taken to walk to work = 16.27 minutes

Therefore,

The percent decrease in the travel time was;

16.27 / 27 x 100

= 0.60 x 100

= 60 %

Answer:

Cubic polynomial has zeros at x=−1x=−1 and 22, is tangent to x−x−axis at x=−1x=−1, and passes through the point (0,−6)(0,−6).

So cubic polynomial has double zero at x=−1x=−1, and single zero at x=2x=2

f(x)=a(x+1)2(x−2)f(x)=a(x+1)2(x−2)

f(0)=−6f(0)=−6

a(1)(−2)=−6a(1)(−2)=−6

a=3a=3

f(x)=3(x+1)2(x−2)f(x)=3(x+1)2(x−2)

Answer:

degree 61 minute 24 second 36.00 (I might be wrong lol)

Step-by-step explanation:

1 degree (°) = 60 arc minutes and 1 arc minute = 60 arc seconds. We denote a an angle given in DMS form using a°b'c''.

Now,

0.41° × (60' / 1°) = 24.6'

and

0.6' × (60'' / 1') = 36''

so that

61.41° = 61° 24' 36''

Step-by-step explanation:

To determine the threshold value of n such that less than 1% of imposter attempts are accepted, we need to find the value of n for which the cumulative percentage of imposter attempts is 1%. From the histogram, we can see that the number of imposter attempts for values of n greater than 0.4 is 0. Therefore, we need to consider the values of n less than or equal to 0.4.

Let's calculate the cumulative percentage of imposter attempts for each range of values of n:

For n > 0.4: 0%

For n > 0.3: (0 + 29) / 1000 = 2.9%

For n > 0.2: (0 + 29 + 15) / 1000 = 4.4%

For n > 0.1: (0 + 29 + 15 + 319) / 1000 = 35.3%

For n > 0: (0 + 29 + 15 + 319 + 643) / 1000 = 97.2%

We can see that the cumulative percentage of imposter attempts is already above 1% for n > 0.2. Therefore, the threshold value of n should be set to 0.2 to ensure that less than 1% of imposter attempts are accepted.

The false alarm rate is the percentage of genuine attempts that are incorrectly rejected. In this case, since we are setting the threshold at 0.2, we can calculate the false alarm rate as the percentage of genuine attempts with a value of n less than or equal to 0.2:

For n <= 0.2: (88 + 133 + 158 + 176 + 188 + 192) / 1000 = 0.935

Therefore, the false alarm rate is 93.5%, which means that almost all genuine attempts will be incorrectly rejected.

To determine the threshold value of n such that less than 1% of genuine attempts are rejected, we need to find the value of n for which the cumulative percentage of genuine attempts is 99%. From the histogram, we can see that the number of genuine attempts for values of n less than or equal to 0.2 is 39. Therefore, we need to consider the values of n greater than 0.2.

Let's calculate the cumulative percentage of genuine attempts for each range of values of n:

For n > 0.2: (39 + 15 + 1) / 1000 = 5.5%

For n > 0.3: (39 + 15 + 1 + 49) / 1000 = 6.4%

For n > 0.4: (39 + 15 + 1 + 49 + 88) / 1000 = 14.2%

For n > 0.5: (39 + 15 + 1 + 49 + 88 + 133) / 1000 = 27.8%

For n > 0.6: (39 + 15 + 1 + 49 + 88 + 133 + 158) / 1000 = 43.6%

For n > 0.7: (39 + 15 + 1 + 49 + 88 + 133 + 158 + 176) / 1000 = 61.4%

For n > 0.8: (39 + 15 + 1 + 49 + 88 + 133 + 158 + 176 + 188

Complete question :

A donation center has 44 small bins with 24 caned food in them they wanna give each food bank the same amount of food there are 4 food banks. How many cans should they give to each food bank?

Answer:

264 cans

Step-by-step explanation:

Number of bins = 44

Number of canned food per bin = 24

Total number of canned foods = (number of bins * number of canned food per bin)

Total number of canned foods = 44 * 24 = 1056

Food is to be distributed equally among 4 banks :

Number of food per bank = 1056 / 4 = 264

The surface area of a conical grain storage tank that has a height of 42 meters and a diameter of 24 meters is 1,670.5 square meters.

The surface area of a cone is calculated using the following formula:

Surface area = πr² + πrl, where π is approximately equal to 3.14, r is the radius of the base of the cone, and l is the slant height of the cone.

In this problem, we are given that the height of the cone is 42 meters and the diameter of the base is 24 meters. The radius of the base is half of the diameter, so the radius is 12 meters. The slant height of the cone can be calculated using the Pythagorean theorem.

l² = 12² + 42²

l² = 1764

l = 42.01 meters

The surface area of the cone is then calculated as follows:

Surface area = πr² + πrl

Surface area = 3.14 * 12² + 3.14 * 12 * 42.01

Surface area = 1,670.5 square meters

=============================================

Explanation:

The original equation is in the form a+b = 1, where

a = sin(theta)

b = cos(theta)

Square both sides of a+b = 1 to get

(a+b)^2 = 1^2

a^2+2ab+b^2 = 1

(a^2+b^2)+2ab = 1

From here notice that a^2+b^2 is sin^2+cos^2 = 1, which is the pythagorean trig identity. So we go from (a^2+b^2)+2ab = 1 to 1+2ab = 1 to 2ab = 0 to ab = 0

Therefore,

sin(theta)*cos(theta) = 0

Answer:

sin ∅ cos ∅ = 0.

Step-by-step explanation:

(sin∅+cos∅)^2 = 1^2 = 1

(sin∅+cos∅)^2  = sin^2∅ + cos^2∅ + 2sin ∅ cos ∅ = 1

But  sin^2∅ + cos^2∅ = 1, so:  

2sin ∅ cos ∅ + 1 = 1

2 sin ∅ cos ∅ = 1 - 1 = 0

sin ∅ cos ∅ = 0.

Answer:

25.75x+9.25

Step-by-step explanation:

9.25 is the constant. You multiply the ticket by the amount of people to get ticket cost. Then you add ticket cost 9.25 to get final answer.

Inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We have been given that the group of friends has no more than $245  to spend on parking and admission.

And the parking is $9.25, and tickets cost $25.75 per person, including tax.

Let the number of people would be p who can go to the amusement park,

So the inequality that expresses the relationship is

⇒ 9.25 + 25.75 × p ≤ 245  

Therefore, inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.

The cities such that this path is \(C_{1}\) → \(C_{2}\) → \(C_{3}\) . . . → \(C_{n}\). Now, if all roads are going towards \(c_{n}+1\), then add  \(c_{n}+1\) at the end of this path. Otherwise, let \(C_{i}\) be the first city in this path such that there is a road from  \(C_{i}\)-1 to  \(c_{n}+1\) and from  \(c_{n}+1\) to  \(C_{i}\). Place  \(c_{n}+1\) between  \(C_{i}\)−1 and  \(C_{i}\) to get the desired path.

Mathematical Induction is a technique of proving a statement, theorem or formula which is thought to be true, for each and every natural number n. By generalizing this in form of a principle which we would use to prove any mathematical statement is 'Principle of Mathematical Induction'.

The question says that between any two cities X and Y, either there’s an

one-way road from X to Y or from Y to X, but not both. Then show that

there is a path from some city A which visits all the cities exactly once.

This problem is very similar to the Football league problem #7 in Homework 1. This problem can be modeled as a directed graph in which cities

are represented as vertices and there’s an edge from vertices X to Y if

there’s a road from cities X to Y. And then, our goal is to find a path

in this graph which visits every vertex in the graph.

The rest of the solution is very similar to the argument in Problem 7 of

homework 1. We use induction of number of cities, say n.

As a base case, if n = 2, there are only two cities X and Y and the path

is simply the edge between X and Y.

For induction hypothesis, assume that the statement is true for any set

of n cities. That is’ for any set of n cities, we can find a path which visits

all the cities exactly once.

Let’s prove the statement for n + 1 cities. Leave out n + 1 th city (say,

\(c_{n}+1\)) and for the remaining n cities, by induction hypothesis, we can find a path which visits all these n cities exactly once. Let us label the cities such that this path is \(C_{1}\) → \(C_{2}\) → \(C_{3}\) . . . → \(C_{n}\). Now, if all roads are going towards \(c_{n}+1\), then add  \(c_{n}+1\) at the end of this path. Otherwise, let \(C_{i}\) be the first city in this path such that there is a road from  \(C_{i}\)-1 to  \(c_{n}+1\) and from  \(c_{n}+1\) to  \(C_{i}\).

Answer:

12 nickels

36 dimes

52 quarters

Step-by-step explanation:

Let x = no. of nickels

3x = no. of dimes

x + 40 = no. of quarters

5x = value of the nickels since each nickel is 5 cents

10(3x) = 30x = value of the dimes since each dime is 10 cents

25(x + 40) = 25x + 1000 = value of the quarters since each quarter is 25 cents

Now, 5x + 30x + 25x + 1000 = 1720     ($17.20 = 1720 cents)

60x + 1000 = 1720

60x = 720

x = 12 nickels

3x = 36 dimes

x + 40 = 52 quarters

Check:  12 nickels are worth $.60

36 dimes are worth $3.60

52 quarters are worth $13

.60 + 3.60 + 13 = 17.20
