Given the polynomial equation x^3 -6x = 3x^2 – 8. Which can be simplified into (x^3) -3(x^2) -6x +8 = 0. The roots of the given equation are x = -2, x = 1 and x = 4. The order of equation also represents the number of roots of the equation given. Since the highest exponent is 3, there also 3 roots. So the answer is D. 2 –2, 1, 4
Answer:
Zero
Step-by-step explanation:
In math, an identity is a number, n, that when added to other numbers, gives the same number, n. The additive identity is always zero. This brings us to the identity property of addition, which simply states that when you add zero to any number, it equals the number itself
Answer:
x=0
Step-by-step explanation:
−6+5x+14=8
(5x)+(−6+14)=8(Combine Like Terms)
5x+8=8
5x+8=8
Step 2: Subtract 8 from both sides.
5x+8−8=8−8
5x=0
Step 3: Divide both sides by 5.
5x
5
=
0

Answer:
the probability of observing 27 or more students 0.818
Step-by-step explanation:
given data
sample n = 28 students
population = 93%
to find out
the probability of observing 27 or more students
solution
we will find Z value for CI 93%
from z table we get Z is 1.812 for Cl 93%
so P(27 ≤ Z ≤ 28)
we know Z = 0.182
= 1 - 0.182
= 0.818
the probability of observing 27 or more students 0.818
Well for question a.) the answer is 3.5 we find this by taking 6-2.5=3.5 th rule is to add 3.5
