Answer: It would not be profitable to sell it back for 100$.
Step-by-step explanation:
It would not be profitable because you might have payed 300-1000$ (Depending what phone you buy) for your phone. It would only be profitable for the older generation of the phones like iPhone 5 and iPhone 6.
Answer:
x=-20
Step-by-step explanation:
1. Expand 3(x+8) : 3x+24
2.Expand -3(7-1/4x): -21*3/4x
3. 3x+24= -21*3/4x
4.<em>Subtract 24 from both sides</em>
3x+24-24= -21*3/4x-24
5.3x= 3/4x-45
6.<em>Subtract 3/4 from both sides</em>
3x-3/4= 3/4x-45-3/4
7.9/4x=-45
8<em>.Multiply both sides by 4</em>
9/4x*4=-45*4
9.9x=-180
10.<em>Divide both sides by 9</em>
9x/9=-180/9
11. x=-20

Answer: D. 0.8202
Step-by-step explanation:
We would assume a binomial distribution for the number of horses presenting with West Nile virus. The formula is expressed as
P(x = r) = nCr × p^r × q^(n - r)
Where
x represent the number of successes.
p represents the probability of success.
q = (1 - p) represents the probability of failure.
n represents the number of trials or sample.
From the information given,
p = 15% = 15/100 = 0.15
q = 1 - p = 1 - 0.15
q = 0.85
n = 10
Therefore,
P(x ≤ 2) = P(x = 0) + P(x = 1) + P(x = 2)
P(x = 0) = 10C0 × 0.15^0 × 0.85^(10 - 0) = 0.1969
P(x = 1) = 10C1 × 0.15^1 × 0.85^(10 - 1) = 0.3474
P(x = 2) = 10C2 × 0.15^2 × 0.85^(10 - 2) = 0.2759
P(x ≤ 2) = 0.1969 + 0.3474 + 0.2759
= 0.8202
Answer:
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
Step-by-step explanation:
i) f(x) = -(x+9)(x-21)
ii) therefore y = f(x) = -
+ 12x + 189 = - ( - 12x +36) + 36 + 189
iii) therefore y = f(x) = - 
+ 225
iv) when x = 6 then y = 255
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
