Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

From the table below, determine whether the data shows an exponential function. Explain why or why not.

Ierofanga [76]

X        Δx                                 y             Δy

3                                               1

1        1 - 3 = - 2                        2             2 - 1 = 1

-1        -1 - 1 = -2                      3            3 - 2 = 1

-3        -3 - (-1) = -2                  4               4 - 3 = 1

So, as you see y in increasing in regular constant intervals, when x also increases in regular constant intervals. => Δy / Δx = constant.

That is the result of a linear function, not an exponential one.

So, the true statement is given by the option <span>(A) No; the domain values are at regular intervals and the range values have a common sum 1. </span>

A firm buys components from two suppliers: 60 percent from supplier A and the rest from supplier B. It so happens that 9 percent

Llana [10]

Answer:

0.114,0.5263

Step-by-step explanation:

Given that a firm buys components from two suppliers:

A : 60% Defective 9%

B:40% Defective 15%

a) the probability that the next component the firm buys is defective

=prob purchased from A and defective + prob purchased from B and defective

= $0.60(0.09)+0.40(0.15)\\= 0.054+0.06\\=0.114$

b) the probability that the component that the firm buys is from supplier B if we know that it is defective

=Prob from B and defective/Prob defective

= $\frac{0.40(0.15)}{0.114} \\=0.5263$
