How can you find the next digit in the quotient?
Bring down the ? to show there are 2 tens
? ones that still need to be divided.
Answers
Bring down the next digit 6 to show there are 2 tens and 6 ones that still need to be divided.
This method of dividing is called the long division method.
In this, we divide the dividend with the divisor and get a quotient and a remainder.
The steps involved are given below :
1. Take the dividend's first digit from the left. Determine whether this digit is bigger than or equal to the divisor.
2. Then divide it by the divisor and write the result as the quotient on top.
3. Subtract the result from the digit and record the difference in the box below.
4. Reduce the dividend by the following digit (if present).
5. Repeat the above steps.

What is meant by the term number line?A number line is a graphical portrayal of numbers on such a straight line in mathematics. A number line has numbers that are sequentially placed at equal distances across its length. It can be extended in any direction indefinitely and is generally denoted horizontally.A number line's numbers increase when moving from left to right as well as decrease when moving from right to left.A number line can represent any type of number, including fractions, decimals, integers, and so on.For the given question;
The distance between point Q and point P is 6 ½ units.
The location of point P is (-4) (seen from the number line).
a. The number could represent point Q are either +2.5 or -10.5.
b. Determine the number;
Add 6 ½ units = 6.5 units to (-4)
= -4 + 6.5
= + 2.5
Thus, point Q = + 2.5
Now, subtract 6 ½ units = 6.5 units to (-4).
= -4 - 6.5
= -10.5
Thus, point Q = + 2.5.-10.5.

Using mathematical operations, the population of Alaska in 2050 will be 8,99,500.
What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.A mathematical action is called an operation. Mathematical operations include addition, subtraction, multiplication, division, and finding the root.So, the population in 2050:
Population increases from 2000 to 2020:733,000 - 622,000 = 1,11,000Population change in 20 years = 1,11,000In 10 years = 1,11,000/2 = 55,500So, poulation in 5050:

Therefore Bill will be able to stay 8 days in his vacation.
Given:
Money Bill saved = $3500
Expenditure for plane tickets = $816
Expenditure per day for hotel = $125
Expenditure per day for food = $100
Expenditure per day for sightseeing = $95
Let the no of days Bill can stay be x.
Therefore,
Expenditure for x days for hotel = $125x
Expenditure for x days for food = $100x
Expenditure for x days for sightseeing = $95x
Therefore according to the question:
125x + 100x + 95x + 816 = 3500
=> 320x = 3500 - 816

Answers
S5 = 20
A6 = 25
A1=
d=
The general formula for arithmetic sequence is:
An = A1 + (n - 1)d
25 = A1 + 6d - d (1)
And the formula for arithmetic sum:
Sn = n(A1 + An)/2
20 = 5(A1 + 25 - d)/2
8 = A1 + 25 - d (2)
We have a system of two equations with two variables.
25 = A1 + 5d
8 = A1 + 25 - d
For both equations, we can solve for d and then equal both equations as follows:
5 - A1/5 = d (1)
A1 + 17 = d (2)
A1 + 17 = 5 - A1/5
A1 = -10.
Now we just replace the value of A1 in equation 1:
d = 7

[tex]y\text{ = mx + b}[/tex]Where m is the slope and b is the y-intercept:
Solving the equation:
-5x - y7 = -8
Add 5x on both sides
-5x + 5x - y7 = -8 + 5x
-7y = -8 +5x
Divide by 7 into both sides:
-7y/7 = (-8 +5x)/7
-y = (-8 +5x)/7
Multiply by -1 to calcel the negative sign:
(-1)(-y) =(-1)* (-8 +5x)/7
y = (8 -5x)/7
y = -5x/7 + 8/7
Now, we need to find the slope of a line perendicular to this line.
"Two lines are perpendicular if and only if their slopes are negative" reciprocals"
So the slope, in this case, is -5x/7
To find the perpendicular line use:
-5x/7 * m = -1
Solve the equation m:
m = (-1)/(-5x/7)
m = 7/5x
So m = 7/5x is the slope of the perpendicular line.
To find the parallel line use:
"Two lines are parallel lines if they do not intersect. The slopes of the"
lines are the same."
So m = -5x/7

In a population of values having a normal distribution with (μ = 126.7) and (σ = 78.3), and we intend to draw a random sample of size (n = 242),

(ii) The probability that a sample of size (n = 242) is randomly selected with a mean greater than 119.2 is 0.932
As per the question statement, a population of values has a normal distribution with (μ = 126.7) and (σ = 78.3) and we intend to draw a random sample of size (n = 242).
We are required to calculate:
(i) The probability that a single randomly selected value is greater is than 119.2
(ii) The probability that a sample of size (n = 242) is randomly selected with a mean greater than 119.2
Let us assume that, a random variable "X" follows normal distribution with mean (μ = 126.7), standard deviation (σ = 78.3) and a sample size of (n = 242).
(i) The probability that a single randomly selected value is greater is than 119.2 is,
P (X > 119.2) = [1 - P(X < 119.2)]
= [1 - P{(X - μ)/σ < (119.2 - 126.7)/78.3}]
= [1 - P{Z < (-0.096)}]
= (1 - 0.462)...[Using Excel Function "NORMSDIST (-0.096)]
= 0.538
≈ 0.54
(ii) The probability that a sample of size (n = 242) is randomly selected with a mean greater than 119.2 is.
P(X bar > 119.2) = [1 - P( < 119.2)]
= [1 - P{(X bar - μ)/(σ/√n) < (119.2 - 126.7)/(78.3/√242)}]
= [1 - P{(X bar - μ)/(σ/√n) < (119.2 - 126.7)/5.033}]
= [1 - P{Z < (-1.49)}]
= (1 - 0.068)...[Using Excel Function "NORMSDIST (-1.49)]
= 0.932

Answers
Using proportions, the number of sections that will be in the finished fence is of:
8.5 sections = 8 and 1/2 (as a mixed number).
What is a proportion?A proportion is a fraction of a total amount, and arithmetic operations such as multiplication or division are used to find the equivalent amounts.
In the context of this problem, we have that the relevant lengths are given as follows:
Each section is of 4.5 feet long.The total length of the fence is of 38.25 feet.Hence, applying a rule of three, as the total length is proportional to the length of each section, the number of sections is given by the division of the total length of the fence by the length of each section, as follows:
Number of sections = 38.25/4.5 = 8.5 sections = 8 and 1/2 (as a mixed number).
