What’s the mean,median,mode and range
Answers
Answer:
Mean=2.1
Median=2
Mode=1,2, and 3
Range=5
Step-by-step explanation:
Mean is all the numbers added up and then divided by the amount of numbers there are, so 0+1+0+2+3+1+3+5+4+2=21, and then 21 divided by 10=2.1
Median is lining all the numbers up least to greatest and then finding the middle number, which is 2.
Mode is the number that appears the most, and since 1,2,3 all appeared twice in the data, they are the mode.
Range is the highest number in the data subtracted by the lowest number in the data, so 5-0=0

Answer:
Q No 33: After solving c-1 we get the answer : 11
Q No 47: a) Money earned for mowing 1 lawns = 15 dollars
b) Money earned for mowing 7 lawns = 105 dollars
Step-by-step explanation:
Question No 33
We are given: a=3, b=2 and c=12
We need to evaluate c-1
It can be solve by placing the value of c, given in question and then subtract 1 from it.
We are given:
[tex]c-1\\Put\:c=12\\=12-1\\=11[/tex]
So, after solving c-1 we get the answer : 11
Question No 47
You can earn 15n dollars for mowing n lawns. How much do you earn for mowing 1 lawn? 7 lawn?
Money earned for mowing n lawns = 15 n
Money earned for mowing 1 lawn:
Put n = 1 in the equation:
[tex]15 n\\=15(1)\\=15[/tex]
So, Money earned for mowing 1 lawns = 15 dollars
Money earned for mowing 7 lawn:
Put n = 7 in the equation:
[tex]15 n\\=15(7)\\=105[/tex]
So, Money earned for mowing 7 lawns = 105 dollars

Solve 2x^2 + x - 15 = 0
Answers
Step-by-step explanation:
[tex] \tt{2 {x}^{2} + x - 15 = 0}[/tex]
USING THE QUADRATIC FORMULA :
Here ,
a = 2 , b = 1 and c = - 15Substitute the values into the quadratic equation :
⇾ [tex] \tt{x \: = \: \frac{ - b \: ± \: \sqrt{ {b}^{2} - 4ac} \: }{2a} }[/tex]
⇾ [tex] \tt{x = \frac{ - 1\: ± \: \sqrt{ {1}^{2} - 4 \times 2 \times ( - 15) } }{2 \times 2}} [/tex]
Simplify
⇾ [tex] \tt{x = \frac{ -1 \:± \sqrt{1 - 8 \times ( - 15)} }{4}} [/tex]
⇾ [tex] \tt{x = \frac{ - 1\:± \: \sqrt{1 + 120} }{4}} [/tex]
⇾ [tex] \tt{x = \frac{ - 1 \:± \: \sqrt{121} }{4}} [/tex]
⇾ [tex] \tt{x = \frac{ - 1\: ± \: \sqrt{ {11}^{2} } }{4}} [/tex]
⇾ [tex] \tt{x = \frac{ - 1 \:± \: 11 }{4}} [/tex]
Now , we can split this into two answers because of the plus minus ( ± ) symbol.
Taking positive ( + ) sign :
⇾ [tex] \tt{x = \frac{ - 1+ 11}{4}} [/tex]
⇾ [tex] \tt{x = \frac{10}{4}} [/tex]
⇾ [tex] \boxed{ \tt{x = \frac{5}{2} }}[/tex]
Again , taking negative ( - ) sign :
⇾ [tex] \tt{x = \frac{ - 1 - 11}{4}} [/tex]
⇾ [tex] \tt{x = \frac{ - 12}{4}} [/tex]
⇾[tex] \boxed{ \tt{x = - 3}}[/tex]

There are various methods of solving quadratic equations. They are as follows :
Solving a quadratic equation by factorisation method : In this method , the second order of polynomial ax² + bx + c is factorised and expressed as the product of two linear factors. Then each linear factors is separately solved to get the required solutions of the equation by applying zero factor property. In zero factor property , if p • q = 0 then either p = 0 or q = 0 .In other words , if the product of two numbers is 0 , then one or both of the numbers must be zero.Solving a quadratic equation by completing the square : In this method , we transpose the constant term ( c ) to R.H.S , then L.H.S to expressed as perfect square expression.Solving a quadratic equation by using formula : In solving a quadratic equation of the form ax² + bx + c = 0 by completing the square , we obtain two roots of x , which are :[tex] \sf{ \frac{ - b + \sqrt{ {b}^{2} - 4ac } }{2a}} [/tex] and [tex] \sf{ \frac{ - b - \sqrt{ {b}^{2} - 4ac } }{2a}} [/tex]. These roots can be written as [tex] \sf{x = \frac{ - b \: ± \: \sqrt{ {b}^{2} - 4ac} }{2a}} [/tex] where a is the coefficient of x² , b is the coefficient of x and c is the constant term. We use this formula to find the required solutions of the given quadratic equation.Hope I helped! ツ

The solutions to the quadratic equation [tex]2x^{2} + x - 15[/tex] are x = 2.5 and x = -3.
Given data:
The quadratic equation is represented as [tex]2x^{2} + x - 15[/tex].
Now, the roots are determined as:
[tex]x_{1}=\frac{-b+\sqrt[]{b^{2}-4ac} }{2a}[/tex]
[tex]x_{2}=\frac{-b-\sqrt[]{b^{2}-4ac} }{2a}[/tex]
The value of a = 2 , b = 1, and c = -1.5
Substituting the values in the equation:
[tex]x_{1}=\frac{-1+\sqrt[]{1^{2}-4*2*(-1.5)} }{2*2}[/tex]
So, the value of [tex]x_{1}=2.5[/tex].
[tex]x_{2}=\frac{-1-\sqrt[]{1^{2}-4*2*(-1.5)} }{2*2}[/tex]
The value of [tex]x_{2}=-3[/tex].
So, the roots are x = 2.5 and x = -3.
Hence, the quadratic equation is solved.

1. A worker in a company work 7 hours in a day, there are 22 working days in a month other than working hours each worker works 8 extra hours in a month, how many hours a worker is working in a full month?
Answers
Answer: A worker is working 162 hours in a month.
Step-by-step explanation:
Working hours per day = 7
Total working days = 22
Extra hours per month = 8
Total hours a worker works in a month = (Working hours per day) x (Total working days) +(Extra hours per month)
Total hours works in month = = 7 x22+8
= 154+8
= 162 hours
Hence, a worker is working 162 hours in a month.
