Answers
Answer:
y=17/2 y=5/2
Step-by-step explanation:
...................
Answer:
[tex]y^{2}[/tex]-11y= -21.25
Factorize the expression [tex]y^{2}[/tex]-11y
y(y-11)= -21.25
Eliminate (y-11)by dividing it over (y-11)
[tex]\frac{y (y-11)}{(y-11)}[/tex] = [tex]\frac{-21.25}{(y-11)}[/tex]
Final answer;
y=[tex]\frac{-21.25}{(y-11)}[/tex]

The theoretical probability of getting a head when you flip a fair coin is
1
2
, but if a coin was actually flipped 100 times you may not get exactly 50 heads, although it should be close to this amount.
If a coin was flipped a hundred times, the amount of times a head actually did appear would be the relative frequency, so if there were 59 heads and 41 tails the relative frequency of flipping a head would be
59
100
(or 0.59 or 59%).
Relative frequency is used when probability is being estimated using the outcomes of an experiment or trial, when theoretical probability cannot be used.
For example, when using a biased dice, the probability of getting each number is no longer
1
6
. To be able to assign a probability to each number, an experiment would need to be conducted. From the experimental results, the relative frequency could be calculated.
The more times that an experiment has been carried out, the more reliable the relative frequency is as an estimate of the probability.
Example
Ella rolls a dice and records the number of times she scores a six. Find the relative frequency that Ella rolls a six on her dice.
Which statement is true about the diagram?
A line has points A, K, B, T. The distance from A to B is 10, the distance from K to B is 5, and the distance from B to T is 4.
K is the midpoint of AB.
B is the midpoint of KT.
AK = BT
AB = KT
Answers
K is the midpoint of AB, which is the correct answer that would be option (A).
What is Midpoint?A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given shows a line segment AT, where the length of line segment AT refers to the distance between its endpoints, A and T.
Here AB = 10, KB = 5, and BT = 4.
Since AB = AK + KB,
We have that 10 = AK+5,
And AK= 10 - 5 = 5.
This means that AK = KB = 5 and K is the midpoint of AB
Therefore, K is the midpoint of AB, which is the correct answer that would be an option (A).

A line contains L(-4, -4) and M(2,3). Line q is in the same coordinate plane but does not intersect LM. Line q contains point N.
Answers
A general line equation can be written as:
[tex]y = a*x + b[/tex]
Where a is the slope and b is the y-intercept.
Here we will find that for N(x₁, y₁), the line q is:
[tex]y = \frac{7}{6}*x + (y_1 - \frac{7}{6}*x_1)[/tex]
If we know that the line passes through the points (x₁, y₁) and (x₂, y₂), then we can write the slope as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case, we know that the line passes through (-4, -4) and (2, 3), then the slope is:
[tex]a = \frac{3 - (-4)}{2 - (-4)} = \frac{7}{6}[/tex]
So the line is something like:
[tex]y = \frac{7}{6} *x + b[/tex]
To find the value of b, we can use one of the two points, for example (2, 3) means that when x = 2, y must be equal to 3, then we can replace these two in the line equation to get:
[tex]3 = \frac{7}{6}*2 + b\\\\3 = \frac{7}{3} + b\\\\3 - \frac{7}{3} = b = 2/3[/tex]
Then the line LM is;
[tex]y = \frac{7}{6}*x + \frac{2}{3}[/tex]
Now we know that line q is in the same coordinate plane, but does not intersect LM. This means that these lines are parallel, and remember that two parallel lines have the same slope, then the slope of line q is also 7/6.
Now we know that line q passes through point N, but we do not know the coordinates of point N, then let's use general coordinates as N(x₁, y₁)
Then line q will be:
[tex]y = \frac{7}{6}*x + c[/tex]
To find the value of c we use the point N.
[tex]y_1 = \frac{7}{6}*x_1 + c\\\\y_1 - \frac{7}{6}*x_1 = c[/tex]
Then the equation of line q is:
[tex]y = \frac{7}{6}*x + (y_1 - \frac{7}{6}*x_1)[/tex]

Prove that the bisector of the vertical angle of isosceles triangle is the perpendicular bisector of the base
Answers
Answer:
We will take two angles and name them 'x'
And their sum must equal 180
So,
x + x = 180
2x = 180
x = 180/90
x = 90
Hence, it is proved that the bisector of the vertical angle of isosceles triangle is the perpendicular bisector of the base.

Multiply total price by 4/5:
55 x 4/5 = (55 x4)/5 = 220/5 = 44
Total after discount is 44
Now add shipping:
44 + 8 = 52
Total paid = £52
Answer:
She will pay $52
Step-by-step explanation:
So she buys them both, which equals 55 dollars. But the website has a deal that is if you buy both of them it's 1/5 of the price off. And 1/5 of 55 is $11, so 55-11=44. You might think you're done but your not. At the end it says they add $8 for the shipping/handling, which is 44+8. This equals 52 dollars. By the way substitute this money sign $ for the one on your page
