Find the average rate of change for the given function from x = −1 to x = 2.
Mashutka [201]

the \: average \: rate \: of \: change =  \frac{f(x2) - f(x1)}{x2 - x1}  \\  \frac{f(2) - f( - 1)}{ 2 -  - 1}  =  \\  \frac{ - 3(2) + 2 - ( - 3( - 1) + 2)}{3} =   \\  \frac{ - 6  + 2 - 3 - 2}{3}  =  \frac{ - 9}{3}  =  - 3

When circuit boards used in the manufacture of compact disc players are tested, the long-run percentage of defectives is 5%. Let
kupik [55]

Answer:

(a) 0.873 (b) 0.007 (c) 0.715 (d) 0.277 (e) 1.25 and 1.09

Step-by-step explanation:

The probability that the random variable X takes the value x is given by P(X=x) = 25Cx 0.05^x0.95^{25-x}. Then,

(a) P(X\leq) = (25C0)(0.05^0)(0.95^{25}) + (25C1)(0.05^1)(0.95^{24}) + (25C2)(0.05^2)(0.95^{23})=  0.873

(b) P(X\geq5) = 1-P(X\leq4) = 1 - (0.873 + (25C3)(0.05^3)(0.95^{22}) + (25C4)(0.05^4)(0.95^{21})) = 1 - (0.873 + 0.12) = 0.007

(c) P(1\leqX\leq4) = (25C1)(0.05^1)(0.95^{24}) + (25C2)(0.05^2)(0.95^{23}) + (25C3)(0.05^3)(0.95^{22}) + (25C4)(0.05^4)(0.95^{21}) = 0.715

(d) P(X=0) = (25C0)(0.05^0)(0.95^{25}) = 0.277  

(e) E(X) = np = (25)(0.05) = 1.25 and Sd(X) = \sqrt{Var(X)} = \sqrt{np(1-p)} = 1.09

Solve the equation for the given variable. justify each step.
s344n2d4d5 [400]

Answer: y=\frac{5-9x}{2}

s=-30+10t

Step-by-step explanation:

9x + 2y = 5; y

9x-9x+2y = 5-9x

2y=5-9x

y=\frac{5-9x}{2}

1/15s - 2/3t = -2; s

(1/15s - 2/3t = -2)*15     ==> Get rid of fraction by multiplying both sides by 15

s - 30/3 t=-30

s-10t=-30

s=-30+10t
