Step-by-step explanation:
8x+8−3(x+4)−7(2−x)
8x+8−(3x+12)−7(2−x)
8x+8−(3x+12)−(14−7x)
8x+8−3x−12−14+7x
(8x−3x+7x)+(8−12−14)
12x-18
Answer:
9 days
Step-by-step explanation:
Experimental probability is the number of times an event occurs divided by the total number of trials of the event.
We know the experimental probability, based on past data, that rain will fall 20% chance.
So, one can expect, that in the next 45 days, rain will fall 20% of the days, according to our experimental probability.
First, we find decimal equivalent of 20%. We divide by 100:
20% = 20/100 = 0.2
Now we multiply this with the number of days:
0.2 * 45 = 9
Thus,
One can expect it to rain 9 days
Answer: 2,6,18,54
Step-by-step explanation:
r=n-k√an/ak
=54-2√54/2
=52√27
r=156√3
Hope this helps bye!
Lemme try k
(x-3)(x+2)
=x^2-3x+2x-6
x^-x-6
x^2-x-30 = 0
(x-6)(x+5) = 0
x-6 =0
x=6
x+5 =0
x=-5
x=6 or x=-5
great I failed
