Answers
The percentile rank of a value with a z-score of 1.33 as given in the task content is; 9.18% (10th percentile).
What is the percentile rank of a value whose z-score is as given in the task content?It follows from the task content that the percentage rank of.the value whose z-score is; 1.33 as in the task content is to be determined.
As evident in the image attached (z-score table) , it can be inferred that a z-score of 1.33 corresponds to 40.82% on the table.
Also, since the z-score is positive, the percentage of data values which are above the z score 1.33 is 50% - 40.82%.
And ultimately, the percentile rank of a value which has a z-score of 1.33 as given in the task content is therefore; 9.18%.

The Sweet Slice pie shop sells organic pies with locally-sourced ingredients. One night after work, Lester brings home part of a bumbleberry pie to share between his mom, dad, sister, and himself. Lester cuts the leftover pie into 4 equal parts, and each family member gets 1 6 of a whole pie.
Answers
Based on the number of equal parts that Lester divided the cake into such that each family member got 1/6 of the whole pie, the proportion of the part of the leftover pie that Lester brought home was 2 / 3
How to find the amount of cake brought back?Lester brought back part of some pie from the Sweet Slice pie shop, and then divided it into 4 equal parts for his family. This led to the family getting 1/6 of the pie each.
To find out how much of the total pie that Lester brought back from Sweet Slice pie shop, you need to add the proportions received by his family:
= 1 / 6 + 1 / 6 + 1/ 6 + 1/6
= 4 / 6
At the simplest form this is:

1-5 Pairs of Angles W.S
Answers
The value of x is 26° and y is 9°.
What is linear pair angles ?A pair of neighboring angles created by the intersection of two lines is known as a linear pair of angles. When two angles share a vertex and an arm but do not overlap, they are said to be adjacent angles. Due to their formation on a straight line, the linear pair of angles are always complementary. So, the total of two angles in a pair of lines is always 180 degrees.
The value of x and y are : x= 26° and y= 9°.
As a linear pair, (5x - 17)° + (3x - 11)° = 180°.
or, 8x - 28°= 180°
8x = 180° + 28°
Therefore, the value of x is 26°.
Now,
3x - 11°= 3×26°-11° = 67°
Again,
67°+90°+(2y+5)° = 180° { being linear pair}.
157°+2y+5° = 180°
or, 2y + 162° = 180°
or, 2y = 180° - 162°
y =
Therefore, the value of y is 9°.
The value of x is 26° and y is 9°.

Answer:
£75 > £70 Therefore Sally is wrong.
Step-by-step explanation:
1. First we need to find the volume of the sand pit
60x40x100= 24,000[tex]cm^{3\\[/tex]
Volume= 24,000[tex]cm^{3\\[/tex]
2. We need to convert 8 liters to [tex]cm^{3\\[/tex] so, all the units are the same
1 liter= 1,000[tex]cm^{3\\[/tex]
8 liters= 8,000[tex]cm^{3\\[/tex]
3. We then do 24,000[tex]cm^{3\\[/tex] divide by 8,000[tex]cm^{3\\[/tex] to see how many bags, we need
24,000[tex]cm^{3\\[/tex]/ 8,000[tex]cm^{3\\[/tex] = 30
so, Sally needs 30 bags
4. We know one bag cost £2.50 to know how much 30 bags cost we do
£2.50 x 30 = £75
so, we know 30 bags cost £75
5. Sally statement was said that it would cost less than £70 which is false as it costs £75
6. Therefore the final answer is £75>£70 so Sally is wrong.
Hello! Can you, please, explain how to solve this kind of equation "Find m+n, if P(x) = (2m-4)x^2+(5-n)x+13 is constant polynomial".
Answers
The value of m + n from getting the values of m and n from the constant polynomial P(x) = (2m - 4)x² + (5 - n)x + 13 is; 7
What is a constant polynomial?
A constant Polynomial is defined as a polynomial is a function of the form f(x) = a
where a is a real number, whose highest degree is zero.
Thus, examples of constant Polynomials are f(x) = 5, g(x) = -11 , h(y) = 7/4
Now, we are given the polynomial expression;
P(x) = (2m - 4)x² + (5 - n)x + 13
From the definition of constant Polynomials, we can say that;
2m - 4 = 0 and 5 - n = 0
Thus;
m = 2 and n = 5
Then, m + n = 2 + 5 = 7

1. In △NBA, BO is a median. If NO=x+3 and OA=2x-9, what is the value of x?
2.In △MTV, TPis an angle bisector. If m∠MTP=12 and m∠MTV=3x-3, find the value of x.
Answers
Answer:
Step-by-step explanation:
1 . In the given triangle ΔNBA BO is a median.
By applying the property of median it divides the opposite side into two equal parts.
Therefore,
NO = OA ...(a)
We have,
NO = x+3 and OA = 2x-9
from (a)
NO = OA
x+3 = 2x-9
∴ 3+9 = 2x-x
∴ x = 12
∴ The Value of x is 12.
Que 2 - In ΔMTV
Given - TP is an angle bisector
m∠MTP = 12 , m∠MTV = 3x - 3.
Ans - TP is an angle bisector which means it divides the angle into two equal parts. (By angle bisector theorem)
∴ m∠MTP = m∠VTP ..... (a)
m∠MTV = m∠MTP + m∠VTP
∴m∠MTV = 2(m∠MTP)
∴3x-3 = 2(12)
∴3x-3 = 24
∴3x = 24 + 3
∴3x = 27
∴ x = 27/3
∴ x = 9
∴ The Value of x is 9.

What transformations take f(x)=3x+1 to g(x)=-3x-5?
Answers
The transformation is:
g(x) = -f(x) - 4
So is a reflection across the x-axis followed by a translation of 4 units downwards.
What transformations take f(x) to g(x)?Here we have the two functions:
f(x) = 3x + 1
g(x) = -3x - 5
So we start at f(x), first we apply a reflection across the x-axis so we change the sign to get:
g(x) = -f(x) = -3x - 1
Now we can apply a translation of 4 units downwards so we get:
g(x) = -f(x) - 4 = -3x - 1 - 4 = -3x - 5
And in this way we transformed f(x) into g(x).

For given triangle, the value of x is 22.
In this question, we have been given three angles of triangle.
We need to find the value of x.
We can observe that (6x - 7)° is an exterior angle.
So, the third angle of the triangle is 180° - (6x - 7)°
We know that the sum of the all angles of the triangle is 180°
2x° + (103 - x)° + [180° - (6x - 7)°] = 180°
2x + 103 - x + 180 - 6x + 7 = 180
2x - x - 6x + 103 + 180 + 7 = 180
-5x + 290 = 180
-5x = 180 - 290
-5x = -110
x = 22
Therefore, for given triangle, the value of x is 22.

How to find the number of fiction and non fiction books?There are 5 times as many fiction books in the class library as there are nonfiction books.
Therefore,
let
x = number of non fiction book.
number of fiction book = 5x
The number of information books is 7 more than the sum of the number of fiction and nonfiction books.
Therefore,
number of information book = 7 + x + 5x
number of information book = 7 + 6x
There are 19 information books in the library.
