45+5.25n>108
-45 -45
————————
5.25n > 63
Divide both sides by 5.25
n>12
Answer:
Step-by-step explanation:
First of all, you have to set up the equation
2x^2 + x -1 = 2 Subtract 2 from both sides
2x^2 + x - 1 - 2 = -2+2 Combine
2x^2 + x - 3 = 0 This factors.
(2x + 3)(x -1 ) = 0
Either
2x + 3 = 0 Subtract 3 from both sides
2x = - 3 Divide by 2
2x/2 = - 3/2
x = - 3/2 which you already know
or
x - 1 = 0 Add 1
x - 1 + 1 = 1
x = 1
the other answer is x = 1
2. find y'' of y = x(x+2)
y=x²+2x
y'=2x+2
3. find y'' of y = (3x+1)(x-2)
y=3x²+x-6x-2
y=3x²-5x-2
y'=6x-5
4. find y'' of y = (3x+4)squared
y=(3x+4)²
y'=2(3x+4)(3)=6(3x+4)=18x+24
5. find y' of y = 3x-2
y'=3
Find the mean of the following data: 0, 5, 30, 25, 16, 18, 19, 26, 0, 20, 28
antiseptic1488 [7]
Answer:
17
Step-by-step explanation:
In order to find a mean in a data set you need to be able to add all numbers provided than divided them by the numbers given. which in this case
- 0+5+30+25+16+18+19+26+0+20+28= 187
- There are 11 number given so we take:
187/11
187/11= 17
Have a nice day!
