torisob [31]

Let x = total sales of baked goods      remember 20% = .20 as a decimal

so the equation would be .20x = $600

divide both sides by .20

                                     .20x/.20 = $600/.20

           

                                                x = $3000 the total sales of baked goods

CHECK:  20% times $3000 = .20 times $3000 = $600

sasho [114]

Answer:

a) 0.1091

b) 0.9994

c) 0.5886

Step-by-step explanation:

X = the number of fish out of 20 that die after 24 hours

x = 0, 1, 2, . . . , 20

X~ Binomial (n= 20, p =0.20)

P(14 survive) = P(X = 6)

= nC_r p^r q^{n-r}= 20C_6 0.2^6\times0.8^{14}=0.1091

Similarly we can find out

P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994

P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886
