We need to use simple division to solve the problem. The number of cards each friend received is 11.
It is said that Landon has 56 cards, he kept 12 cards for himself, so we can subtract 12 cards from the whole lot to get the total number of cards he distributes among his friends.
56-12=44
There are 44 cards that he will distribute among his friends equally, we can get that by simply dividing the total number of cards by the number of friends which is 4.
number of cards for each friend=44/4=11
Therefore the number of cards each friend received is 11.

Prediction of the mean value of the dependent variable y for values of the independent variables x 1, x 2, . . . , x q that are outside the experimental range is called extrapolation of data.
What is extrapolation of data?In statistics and mathematics, especially in the branch of data-science it is quite common to use a range of values from a parameter to predict the values of the dependent variable.
One of the most common applications of this is regression equations, when pairs of one of the independent variables with the dependent variable are used to predict the dependent variable.
In the case of this problem, we want to predict the dependent variable, but with values that are outside the experimental range, hence we extrapolate the data inside the experimental range for values that are outside the experimental range.

The accurate scale drawing shows a car and a lamp post.
The car has a real width of 1.5 metres.
Find an estimate for the real height, in metres of the lamp post.
An estimate of the real height of the lamp post is 9m.
What is the estimate of the real height?The first step is to determine the scale of the drawing. The scale can be determined by dividing the height of the lamp post by the height of the car. The height of the lamp post when measured with a ruler is 10.8 cm and the height of the car is 1.8cm
Scale = length of the lamp post / height of the car
10.8 / 1.8 = 6
Now, multiply the scale by the width of the car.
The real height of the lamp post = 6 x 1.5 = 9m

Answer:
(f∘g)(12) = 24
Step-by-step explanation:
Pre-SolvingWe are given the functions f(x)=4x+8 and [tex]g(x)=\sqrt{x+4}[/tex]. We want to find (f∘g)(12).
(f∘g)(12) means that we first find the value of g(12), and then plug that value into f(x).
SolvingFirst, we find g(12). To do this, substitute x as 12.
[tex]g(12) = \sqrt{12 + 4}[/tex]
Add 12 and 4 together under the radical.
[tex]g(12) = \sqrt{16}[/tex]
Take the square root of 16.
g(12) = 4
Now, substitute 4 as x in f(x) = 4x + 8.
f(4) = 4(4) + 8
Multiply.
f(4) = 16 + 8
Add 16 and 8 together.
f(4) = 24
f(4) has the same value as (f∘g)(12), since 4 is the value of (g)(12), and then the value of g(12) was plugged in as x in f(x).
Therefore, (f∘g)(12) is 24.

the diagram shows triangle ABC. D is on the point AB such that CD is perpendicular to AB. AC=9.4cm, AD=5.2cm and BD=7.8cm. Work out the size of angle ABC.
Answer:
45°
Step-by-step explanation:
Triangles ADC and BDC are right triangles, since CD⊥AB.
Use Pythagorean to find the length of CD:
CD² + AD² = AC²CD² + 5.2² = 9.4²CD² = 9.4² - 5.2²CD² = 61.32CD = √61.32CD = 7.83Use trigonometry to find the angle ABC:
tan (∠ABC) = CD/BDtan (∠ABC) = 7.83/7.8tan (∠ABC) = 1.0 (rounded)m∠ABC = arctan 1m∠ABC = 45°2w - 15w - 18 = -83 solve for w simplify as much as possible
Answer:
w = 5
Step-by-step explanation:
2w - 15w - 18 = -83
combine w on left side:
-13w - 18 = -83
add 18 to both sides:
-13w - 18 + 18 = -83 + 18
-13w = -65
divide both sides by -13:
-13w/-13 = -65/-13

How do you reflect the image over the x-axis
The coordinates of the image of any point P(x, y), from any geometric locus, after being reflected over the x-axis.
How to reflect any geometric locus over the x-axis
Geometric loci are geometrical constructions formed by one or more points, these may represent a point or a figure formed by finite or infinite set of points.
Let P(x, y) = (x, y) a point of the geometric locus, which has to be modified by using reflection over the x-axis. This can done by adding the vector (- 2 · x, 0) to the vector P(x, y):
P'(x, y) = P(x, y) + (- 2 · x, 0)
P'(x, y) = (x, y) + (- 2 · x, 0)
P'(x, y) = (- x, y)
Where P'(x, y) is the image of point P, from any geometric locus, after making the reflection over the x-axis.

This equation represents the approximate height, h, in meters, of the ball above the ground after it falls for t seconds.
h = -5t2 + 45.
How can one determine a function's maximum height?
The vertex, which is a maximum (or minimum) in a parabola, can be located by solving the square (yuck!) or by using the formula x = -b/2a. By re-entering the original equation with this x value as the vertex's x, we can determine the appropriate maximum height.
By multiplying "D * tan (theta)," where "tan" is the tangent of angle theta, you can get the height of the item of interest. For instance, rounding up, the height is 40 tan 50 = 47.7 meters if theta is 50 degrees and D is 40 meters.

Tia rounds a number, x, to 3 sf.

Write the error interval for x in the form a ≤
x < b.
If Tia rounds a number, x, to 3 sf and the result is 7.68. the error interval for x in the form a ≤ x < b is 7.685 ≤ x ≤ 7.684
What is error interval?The accuracy thresholds that apply when a number has been rounded or truncated are known as error intervals. In other words, they represent the range of values that a number might have taken had it not been rounded off or truncated.
To do this, we consider the smallest and largest numbers that could be rounded or truncated to a value while maintaining a certain level of accuracy.
We know that if this digit is smaller than 5, then we round down.
Then the largest number that can be rounded down to 7.68 is:
7.684
Now we want to find the smallest number that can be rounded up to 7.68
We know that if the next digit is 5 or bigger, then we round up.
Then the number 7.685 is rounded up to 7.68
Then the error interval is:
7.685 ≤ x ≤ 7.684
