Answer:
The value if this expression is 5,616 because it says it in the answer choice or box and the person did 12 times 13 and more
1.67x[10^(-20)] 1.67x[10^(-24+28)]
--------------------- = -------------------------- =
9.11x[10^(-28)] 9.11
.183315(10^4)=1833.15
The proton mass is about 1833 times an electron mass
Hope this helps!
The answer is:
(null hypothesis) u=2.7; Ha(alt hypothesis): u<2.7
(Use order of operations(PEMDAS))
14(4)+28-12(5)
56+28-60
84-60
24
solution=24
We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials
