- In Problems 1–6, use ZERO (or ROOT) to approximate the smaller of the two x-intercepts of each equation. Express the answer rounded to two decimal places. 1. y = x? + 4x + 2 4. y = 3x? + 5x + 1 2. y = x? + 4x – 3 3. y = 2x? + 4x + 1 5. y = 2r – 3x – 1 6. y = 2x? – 4x – 1arrow_forward2.2 Deffetrentiate the following: 3x +1 a) f (x) = 2x + 5 b) S(x) = (emcot x) (8x – 1)2 c) f (x) = (3x – 1)? d) f(x) = x*arrow_forwardLet A = (-0,0), B=(0,00) then AŬB=arrow_forward

For a publishing project we need 205 sheets and so purchase 21 packs. Due to manufacturing imperfections the packs do not always contain 10 sheets. If we denote by X; the number of sheets of paper in the ith pack then (0.1 if k = 9 0.8 if k = 10 P(X₁ = k) = 0.1 if k = 11 0 if k {9, 10, 11}. We further assume that the random variables X; are independent. (a) Find the mean and standard deviation of Xi. (b) Denote by X the total number of paper sheets we have purchased, X = X₁++X21. Calculate the mean and standard deviation of X. (c) Estimate the probability that we have purchased enough sheets for our project, 205). You should use the continuity correction. i.e. P(Xarrow_forward
