A divisibility rule is a simple method for determining whether or not an integer is divisible by a fixed divisor without having to divide it by looking at its digits.

The three-digit divisibility rule asserts that if the sum of a whole number's digits is a multiple of three, the original number is also divisible by three.

The total of all the digits in 1377 is 1+3+7+7 = 18. Because 18 is divisible by three, 1377 is likewise divisible by three. The quotient is 1377 3 = 459, and the remainder is 0.

The divisibility rule of 9 asserts that if a number's sum of digits is divisible by 9, the number is divisible by 9 as well.

The three-digit divisibility rule and the nine-digit divisibility rule are quite similar. As previously stated, the divisibility rule for the divisibility test of 3 asserts that if a number's sum of all digits is divisible by 3, the number is also divisible by 3. The divisibility rule of 9 is similar to the divisibility rule of 3, in that a number is said to be divisible by 9 if the sum of all of its digits is divisible by 9.

Take 52884 for example. 52884 is divisible by three since the total of all digits is 5+2+8+8+4 = 27. The quotient is 52884 ÷ 3 = 17628, and the remainder is 0. It's worth noting that the sum of the digits is 27 is 2 + 7 = 9, which is likewise divisible by three.

Using vectors, and the relation between velocity and position, it is found that:

a) The speed is given by: v(t) = 2i - 5j.

b) The position vector p at time t hours is: p(t) = (2t  + 8)i + (-5t + 3)j.

c) The ship is due north of the lighthouse at a time of 6 seconds.

d) The ship is 23 miles from the lighthouse at this point.

The position function is the integral of the velocity function.

As stated in the problem, the velocity is constant, hence:

The speed is given by: v(t) = 2i - 5j.

The position is the integral of the velocity, hence, integrating each component.

[tex]p(t) = \int v(t) dt[/tex]

[tex]p(t) = \int (2i - 5j) dt[/tex]

p(t) = (2t + k1)i + (-5t + k2)j.

Considering the initial position, we have that:

k1 = 8, k2 = 3.

Hence:

The position vector p at time t hours is: p(t) = (2t  + 8)i + (-5t + 3)j.

The ship is due north of the lighthouse(20i - 50j) when it has the same x-coordinate, hence:

2t + 8 = 20

2t = 12

t = 6.

Hence:

The ship is due north of the lighthouse at a time of 6 seconds.

The position of the ship at t = 6 seconds is:

(2(6) + 8)i + (-5(6) + 3)j = 20i -27j.

The distance is given by:

|-50 - (-27)| = |-23| = 23.

The ship is 23 miles from the lighthouse at this point.

The expression for Total discount for 20 group tickets is 5 m, Amount of discount per ticket is 0.25 m, Number of tickets is 20 and Cost of buying 20 single ticket is 20 m.

We have:

a discount of 25% per ticket if a group buys 20 or more tickets.

The expression 20 m - 20 (0.25 m) describes the total cost of buying 20 tickets for a group.

Total discount for 20 group tickets will be:

Total discount = 20 × 0.25 m = 5 m

Amount of discount per ticket = 5 m / 20 = 0.25 m

Number of tickets = 20

Cost of buying 20 single ticket = 20 m

where m = cost of buying 1 ticket.

Considering the definition of an inequality, the number of days Sebastian can afford to rent while staying within his budget is less than or equal to 6.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

In this case, you know that:

Being "d" the number of days Sebastian can afford to rent while staying within his budget, the inequality that expresses the previous relationship is

40.50×d - 400×0.12 ≤ 210

Solving:

40.50×d - 48 ≤ 210

40.50×d ≤ 210 + 48

40.50×d ≤ 258

d ≤ 258÷ 40.50

Substitution method of solving a system of equations replaces the variable with a value while elimination method of solving a system of equations removes the variable from the equations.

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

example:

Given two equations: x + 3y = 7 and 2x - 4y = 24, find the solution.

Using substitution method, express one equation to an equation of one of its variables(in terms of the other variable).

x + 3y = 7   ⇒   x = 7 - 3y

Substitute it to the other equation and solve for y.

2x - 4y = 24

2(7 - 3y) - 4y = 24

14 - 6y - 4y = 24

-10y = 10

y = -1

Substitute the value of y in any of the equations and solve for x.

x = 7 - 3y

x = 7 - 3(-1)

x = 7 + 3

x = 10

Hence, the solution is (10 , -1).

Using elimination method, multiply the first equation by 2 so that if we add or subtract it to the second equation, a variable will be removed.

x + 3y = 7   ⇒   2x + 6y = 14

Subtracting equation 2 from equation 1,

2x + 6y = 14

2x - 4y = 24

0x + 10y = -10

y = -1

Substitute the value of y in any of the equations and solve for x.

x + 3y = 7

x + 3(-1) = 7

x = 7 + 3

x = 10

Hence, the solution is (10 , -1).

Answer:

9 cupcakes on Saturday

Step-by-step explanation:

(p + 3) more than p is p + p + 3 = 2p + 3

on Saturday she baked p

on Sunday she baked 2p + 3 , then

p + 2p + 3 = 30

3p + 3 = 30 ( subtract 3 from both sides )

3p = 27 ( divide both sides by 3 )

p = 9

Measure of angle 2 i.e. m∠2 = 130°

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Also, ∠5 = ∠4 = 50° (alternate interior angles)

As, ∠4 and ∠2 are supplementary angles

Hence, ∠4 + ∠2 = 180°

50° + ∠2 = 180°

∠2 = 130°

The mean number of heads is 8.

In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p. The probability of observing x successes in N trials is calculated using the binomial distribution, with p standing for the probability of success on a single trial. According to the binomial distribution, p is fixed throughout all trials.

The probability of success raised to the power of the number of successes and the probability of failure raised to the power of the difference between the number of successes and the number of trials are multiplied to create the binomial distribution. In mathematics and statistics, the binomial distribution is the likelihood that a specific outcome in a series will occur when there are only two possible outcomes: success or failure. Bi is the prefix for two.

Use the formula for the mean for the Binomial Distribution: μ = np

• n = 16

• p = ½

Therefore μ = 16 × ½ = 8
