Answer:

<em>Answer</em><em> </em><em>is</em><em> </em><em>-6</em>

Step-by-step explanation:

given \: q(x) = 2x - 1 \\ and \: r(x) =  - 2x \\ r(q(2)) = r(2(2) - 1) \\ \:  \:   = r(4 - 1) \\  = r(3) \\  =  - 2(3) \\  =  - 6 \\ therefore \: r(q(2)) =  - 6

Edwin deposited money into a savings account that pays a simple annual interest rate of 1.4%. He
mafiozo [28]
<h3>The deposited sum of money by Edwin is $350.</h3>

Step-by-step explanation:

Let us assume that the amount deposited  = P

The rate of interest  = 1.4%

The Simple Interest earned  = $24.50

Time  = T = 5 years

Now, as we know:

SIMPLE INTEREST  = \frac{P \times R \times T}{100}

\implies 24.50  = \frac{P \times 1.4 \times  5}{100} \\\implies P = \frac{24.50 \times 100}{1.4 \times 5}  = 350\\\implies P = 350

Hence, the deposited sum of money by Edwin is $350.

Each time Caroline goes shopping she decides whether or not to buy fruit.
DiKsa [7]

Let event A = Caroline buys fruit, event B = Caroline buys CD, Ac and Bc are complementary events.

Events AB, ABc, AcB and AcBc are jointly exhaustive and disjoint, hence P(AB) + P(ABc) + P(AcB) +P(AcBc) =1.

Events A and B independent, hence Ac and Bc independent too and probability P(AcBc) = P(Ac)*P(Bc) = (1 - P(A))(1-P(B)) = 0.6*0.4 = 0.24.

Required probability P(AB + ABc + AcB ) = P(AB) + P(ABc) + P(AcB) = 1- P(AcBc) = 1 - 0.24 = 0.76.

Answer: Probability that Caroline buys fruit, a CD or both is 0.76.
