Step-by-step explanation:
come on !
how do you create a line ?
you mark 2 points, take a ruler and draw a line through both points (and extend the line beyond the points as far as the chart goes).
how do you find points ?
you think about a nice value for x (really, any value on the x-axis of the chart is OK) and then calculate y.
you mark the point at this x, y coordinates.
you know, the x-axis is the horizontal coordinate line, and the y-axis is the vertical coordinate line.
so, I would pick x =0. that gives us y = 0 + 0.5 = 0.5.
and maybe x = 2. that gives us y = 2 + 0.5 = 2.5
so, you have (0, 0.5) and (2, 2.5) as points.
and then simply do as described above.

Answer:
4%
Step-by-step explanation:
using a calculator, you can do 5200/130000 and get 0.04
:)
Answer:
4%
Step-by-step explanation:
Given:
Present population = 130,000
Future population = 135,200
Find:
Increase in percent
Computation:
Increase in population = Future population - Present population
Increase in population = 135,200 - 130,000
Increase in population = 5,200
Increase in percent = [Increase in population / Present population]100
Increase in percent = [5,200/130,000] 100
Increase in percent = 4%

Sipho travelled 480km for 6 hours .Calculate his average speed
Answer:
Average speed = 80km
Step-by-step explanation:
[tex]AS = \frac{480km}{6} \\ AS = 80km[/tex]
as means average speed
Sipho travelled 480km in 6 hours -> In an hour, Sipho travelled 1/6 of the distance.
So, in an hour, Sipho travelled : 480 x 1/6 = 80km
In an hour, he travelled 80km -> his average speed is 80km/h

−15x+54 and g(x)=x-6g(x)=x−6, find f(x)\cdot g(x)f(x)⋅g(x) and express the result in standard form.
Answer:
x^3 - 21x^2 + 144x - 324
Step-by-step explanation:
f(x) = x^2 - 15x + 54
g(x) = x - 6
To find f(x) x g(x), you just substitute the values of f(x) and multiply it with g(x).
(x^2-15x+54)(x-6) = x^3 - 15x^2 + 54x - 6x^2 + 90x - 324
= x^3 - 21x^2 + 144x - 324

Alan owns a shop one week he recorded the number of orders placed each day. From Monday the Friday the mean number of orders placed per day was 72 for the whole week the mean number was 93. On Saturday 152 orders were placed.
Work out the mean number of orders placed on Sunday
34 orders were placed on Sunday.
Mean numbersGiven that from Monday to Friday the mean number of orders placed per day was 72 and for the whole week the mean number was 93, while on Saturday 152 orders were placed, to work out the mean number of orders placed on Sunday you must perform the following calculation:
72 x 5 + 93 x 2 = X360 + 186 = X546 = X546 - 360 - 152 = X34 = XTherefore, 34 orders were placed on Sunday.

For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.
What is Standard normal distribution?The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.
In order to calculate the value of the P(z≤0.42), we need to check the value of 0.42 in the z-table, As the Z-table is already given and in the table, the value of z is 0.6628, therefore,
[tex]P(z\leq 0.42)\\\\=0.6628 \approx 66\\\\= 66\%[/tex]
Hence, For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.

Forty-four students go on a field trip. The students are divided into groups of 7 students. How many groups of 7 will there be?.
6
To solve this problem, you need to divide the total number of students going on the field trips with the number of students in each group.
44/7
= 6 R 2
Since, I assume there can only be groups of 7, the answer is 6.
The coordinates for one vertex of a rectangle are (1. 25,1). The length of the rectangle is 2. 5 units, and the width of the rectangle is 1. 25 units. Draw this rectangle on the coordinate grid
Answer:
(-1.25,-0.25).
Step-by-step explanation:
The length of the rectangle is 2.5 units. To find the point that is 2.5 units from (1.25,1), count 2.5 units to the left of the point. The x-coordinate will change and the y-coordinate will remain the same. This point is (-1.25,1).
The width of the rectangle is 1.25 units. To find the point that is 1.25 units from (1.25,1), count 1.25 units down from the point. The y-coordinate will change and the x-coordinate will remain the same. This point is (1.25,-0.25).
The coordinates of the final point to plot are found using the new x- and y-coordinates. This point is (-1.25,-0.25).Nabin is twice as old as Kiran. Two years hence he will be six years older then Kiran. Find there present age
