Answer:
10 and 11
Step-by-step explanation:
Let the first integer be x.
Then the next one, since it's consecutive, must be (x+1).
The two equals 21. Thus:
Combine like terms:
Subtract 1 from both sides:
Divide both sides by 2:
So, the first integer is 10.
And the second integer is 10+1=11.
To find percent error, you subtract the actual number from your estimate, take the absolute value, and divide by the actual number.
l 96 - 118 l
l -22 l
l 22 l
l 22 l / 118
0.19% (this was rounded)
Hope this helps!
Since it is a polynomial
for the zero 4 you can write (x-4)
for the zero -14 you can write (x+14)
for the zero 5+8i since it is complex it will be accompanied with its conjugate 5-8i so you can write (x-(5+8i) and (x-(5-8i)) =(x^2-10x+89)
so
(x-4)(x+14)(x^2-10x+89)
expanding
x^4-67x^2+1450x-4984=0
Answer:
Team D has the most variability; range of ages from 8 years old to 58 years old
Team A has the oldest of ages
Step-by-step explanation:
Team D has the most variability; range of ages from 8 years old to 58 years old
Team A has the oldest of ages, with the oldest being 62 years old and youngest being 22 years old
Team B has the youngest member at 15 years
Team C has the youngest member at 22 years.
Team D has the youngest member at 8 years old.
The oldest group would be the one with the highest age for the mean and highest age range.
