Answer:
8x^2+3x
Step-by-step explanation:
What I read is 2x+8x^2-4x+5x
combining like terms means putting the terms that have the same variable part together
8x^2 is the only one that doesn't have any terms like it as far as the variable part
so 8x^2+2x-4x+5x
We just need to figure out 2-4+5 which is -2+5=3
So the answer is 8x^2+3x
Answer:
a) 0.172
b) 0.167
c) 0.1404
Step-by-step explanation:
Margin of error, E = 
here,
p = probability of the event
n = sample size
a) n = 30
p = 10 ÷ 30 = 0.333
Therefore,
E = 
= 2 × 0.0861
= 0.172
b) n = 30
p = 21 ÷ 30 = 0.7
Therefore,
E = 
= 2 × 0.0836
= 0.167
c) n = 30
p = 22 ÷ 50 = 0.44
Therefore,
E = 
= 2 × 0.0702
= 0.1404
Answer:
1188 grams
Step-by-step explanation:
You want the 12g of sugar to be 1% of the whole solution.
So, say you add grams of water. The solution will be composed of 12 grams of sugar and grams of water, for a total of grams.
So, the ratio "sugar/total" will be
and we want this ratio to be 1%, i.e. 1/100:
Multiply both sides by 100 and to get
Subtract 12 from both sides:
So, a solution composed of 1188 grams of water and 12 grams of sugar will be 99% water and 1% sugar.
Answer:
?
Step-by-step explanation:
54,675+33,548,000x^1+a^2=
get rid of ^1 cuz that doesn't change the value
a^2 can be written as 2a because a^2= a*a and 2a= a*a
54,675+33,548,000x+2a
54,675+33,548,000x= -2a-54675
33,548,000x=-2a-54675
16774000x=-a-27337.5
x=-a - 27337.5
x=-a-27337.5/ 16774000
I obviously know this isn't a real question but here
