Question 5
Which of the following is true?
O1-51-4
O1-41 <1-51
O1-51-5
O 1-41 > 151
Question 6
Answers
After simplification, the second option |−4| < |−5| is true.
In the given question,
There are four options. We have to check which option is true.
The given options are
1) |−5| < 4
2) |−4| < |−5|
3) |−5| = −5
4) |−4| > |5|
To find the true option we solve the given option one by one.
The first option is
|−5| < 4
Now solving
As we know that every value from the mod always give positive value.
So if we solve |−5| then the value is 5 and 5 is greater than 4. But in the given statement states that 4 is greater that 5. So the first statement is wrong.
Now solving the second statement.
|−4| < |−5|
After solving |−4|, the value is 4 and |−5| is 5.
So the simplified statement is 4 < 5 which is true.
Hence, the second statement is true.
Now we get the true statement so we haven't solve any further option.
If you want the solve next option the the way of solving the option is same.
Hence, the second option |−4| < |−5| is true.

angela is following this recipe to make biscuits. angela uses 3.3 litres of syrup. how much sugar is needed in kg
Answers
The quantity of sugar that is needed in kg would be = 1.8kg
What is recipe?Recipe is defined as the list of components of ingredients that makes up a food product.
From the recipe given by Angela, the quantity of syrup that is used to make up to 14 biscuits= 275 ml.
The quantity of sugar that is used to make up to 14 biscuits= 150g
Therefore the quantity of sugar that would be used for syrup of 3.3 liters would be= X
That is;
275ml = 150g
3.3L = X
Convert 3.3L to ml = 3,300ml , then make x the subject of formula;
X = 3300×150/275
X = 495000/275
X= 1,800g
Then convert 1,800g to kg by dividing through with 1000;
1800/1000 = 1.8 kg
Therefore, the quantity of sugar that would be used for 3.3L of syrup would be 1.8kg.

The given circle equation [tex]x^2+4x+y^2-2y-4[/tex]=0 has center(-2,1) and radius r=3.
What is circle equation?
For all values of g, f, and c, the general equation of any type of circle is written as x2 + y2 + 2gx + 2fy + c = 0. The collection of all points in a plane that maintain a fixed, finite distance r from a fixed point is known as a circle. O = (a,b). The definition of a circle on the coordinate plane can be expressed using the equation of a circle. The equation is where r is the radius and if the centre of the circle is at the origin of the coordinate plane.
Here the given circle equation is,
=> [tex]x^2+4x+y^2-2y-4[/tex]=0
=>[tex]x^2+4x+y^2-2y =4[/tex]
[tex]= > x^2+4x+4+y^2-2y+1=4+4+1\\= > (x+2)^2+(y-1)^2=9[/tex]
we know that equation of circle is [tex](x-a)^2+(y-b)^2=r^2[/tex]
Here (a,b)= center and r is radius.
=> [tex](x+2)^2+(y-1)^2=3^2[/tex]
Then the Center (a,b)=(-2,1) and radius r=3.

0.05093 is the probability that exactly 13 students will take up application development in the coming year .
Describe probability using an example?

Poisson random variable(number of students taking up Application Development in the coming year)(x)=13
Poisson distribution = P(X = x) = e^−λ (λ)^x/ x!

The evaluation of the square roots of the numbers using prime factorization gives;
11. √1156 = 32
12. √1024 = 32
13. √1225 = 35
14. √1764 = 42
15. √1936 = 44
What are prime factors?Prime factors are the factors of a number that are also prime numbers.
The square roots of the numbers found using prime factorization are as follows;
11. √1156
1156 ÷ 2 = 578
578 ÷ 2 = 289
289 ÷ 17 = 17
17 ÷ 17 = 1
√1156 = √(2 × 2 × 17 × 17) = √(2² × 17²)
√1156 = √(2² × 17²) = 2 × 17 = 34
√1156 = 34
12. √1024
1024 ÷ 2 = 512
512 ÷ 2 = 256
256 ÷ 2 = 128
128 ÷ 2 = 64
64 ÷ 2 = 32
32 ÷ 2 = 16
16 ÷ 2 = 8
8 ÷ 2 = 4
4 ÷ 2 = 2
Therefore; √(1024) = √(2×2×2×2 ×2×2×2×2×2×2) = √(2¹⁰) = 2⁵ = 32
√1024 = 32
13. √1225
1225 ÷ 5 = 245
245 ÷ 5 = 49
49 ÷ 7 = 7
7 ÷ 7 = 1
Therefore;
√(1225) = √(5 × 5 × 7 × 7) = √(5² + 7²) = 5 × 7 = 35
14. √1764
1764 ÷ 2 = 882
882 ÷ 2 = 441
441 ÷ 3 = 147
147 ÷ 3 = 49
49 ÷ 7 = 7
7 ÷ 7 = 1
√1764 = √(2 × 2 × 3 × 3 × 7 × 7) = √(2² × 3² × 7² = 2 × 3 × 7 = 42
15. √1936
1936 ÷ 2 = 968
968 ÷ 2 = 484
484 ÷ 2 = 242
242 ÷ 2 = 121
121 ÷ 11 = 11
11 ÷ 11 = 1
Therefore; √(1936) = √(2 × 2 × 2 × 2 × 11 × 11) = √(2⁴ × 11²) = 2² × 11
√(1936) = 2² × 11 = 44

when 1515 is appended to a list of integers, the mean is increased by 22. when 11 is appended to the enlarged list, the mean of the enlarged list is decreased by 11. how many integers were in the original list?
Answers
In the initial list, there were 4 integers.
We have the following system if the mean is m, x is the list's initial sum, and n is the number of integers in the list:
m = x/n , m + 2 = (x + 15) / (n + 1) and m + 1 = (x + 16) / (n + 2).
The initial equation is x = mn.
Therefore, changing x in the other two equations:
m + 2 = (mn + 15) / (n + 1) ..............(1)
m + 1 = (mn + 16) / (n + 2)...............(2)
Based on equation (1):
(m + 2)(n + 1) = mn + 15
mn + m + 2n + 2 = mn + 15
m + 2n + 2 = 15
m + 2n = 13
m = 13 - 2n.
Now change m in equation (2) to:
13 - 2n + 1 = ( n(13 - 2n) + 16) / (n + 2)
14 - 2n = (13n - 2n^2 + 16) / (n + 2) Through-multiplication by n + 2:
(14 - 2n)(n + 2) = 13n - 2n^2 + 16
14n + 28 - 2n^2 - 4n = 13n - 2n^2 + 16
10n + 28 = 13n + 16
12 = 3n
n = 4.
Hence, there were 4 integers in the original list.

A Douglas Fir costs $_____
and a Noble Fir costs $_______
Answers
Solving the system of equations we can see that:
A Douglas Fir costs $33.50_and a Noble Fir costs $47.75__How to write and solve the system of equations?
We can define the variables:
x = price of a Douglas Fir trees
y = price of a Noble Fir trees.
By using the given information we can write:
6x + 16y = 986
6x + 24y = 1368
That is our system of equations
If we take the second equation and we subtract the first one we get.
(6x + 24y) - (6x + 16y) = 1368 - 986
8y = 382
y = 382/8 = 47.75
now that we know the value of y, we can find the value of x using the first equation.
6x + 16y = 986
6x = 965 - 16y
x = (965 - 16y)/6
x = (965 - 16*47.75)/6 = 33.5

[tex]\textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2 \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases}\implies 15^2=x^2+(x+3)^2 \\\\\\ 225=x^2+(x^2+6x+9)\implies \implies 225=2x^2+6x+9 \\\\\\ 0=2x^2+6x-216\implies 0=2(x^2+3x-108) \\\\\\ 0= x^2+3x-108\implies 0=(x-9)(x+12)\implies x= \begin{cases} 9 ~~ \checkmark\\\\ -12 \end{cases}[/tex]
