Which could be the entire interval over which the function, f(x), is negative?

lana [24]

For this case we have a function of the form:

y = f (x)

Where,

x: independent variable

y: dependent variable

To answer the question, we must see in the table the values of the independent variable x, for which the values of the dependent variable f (x) are negative.

We have then that the interval that fulfills this condition is from minus infinity to minus 4 without including the 4.

Thus,

(–∞, –4)

Answer:

The entire interval over which the function, f(x), is negative is:

D) (–∞, –4)

Annette [7]

Answer: C) (1,0.80) represents the unit rate. E) (25,20) represents the price of a necklace with 25 beads

Step-by-step explanation:

(1, 0.80) represents the unit rate.

(25, 20) represents the price of a necklace with 25 beads.

$\frac{y}{x}$ = unit rate → $\frac{4}{5}$ = 0.80; $\frac{12}{15}$ = 0.80; $\frac{16}{20}$ = 0.80

Point (1, r) → (1, 0.80) represents the unit rate.

25(0.80) = 20; thus, (25, 20) represents the price of 25 beads.

Hope this helps

Otrada [13]

Answer:

The square root of terms separated by addition and subtraction cannot be calculated individually.

Step-by-step explanation:

In order to calculate the square root, we would need a monomial or a factored expression. We do not have that, so we cannot take the square root.

Answer:

a) MA conditional with C can be interpreted as A which is known and C which is unknown match

b) 10/11

c) 2/11

Step-by-step explanation:

A={A is the guilty party}

$M_A$ = {A blood type matches that of the guilty party}

C = {B is the guilty party}

$M_C$ = {B blood type matches that of the guilty party}

a) The chance is 10% because MA conditional with C can be interpreted as A which is known and C which is unknown match

b) the probability that A is the guilty party is given by $P(A/M_A)$ . Using bayes theorem:

$P(A/M_A)=\frac{P(M_A/A)P(A)}{P(M_A/A)P(A)+P(M_C/C)P(C)} =\frac{1*1/2}{(1*1/2)+(1/10*1/2)} =\frac{10}{11}$

c) the probability that B’s blood type matches that of the guilty party is given as $P(M_C/M_A)$ . Using LOTS Therefore:

$P(M_C/M_A)=P(M_C/M_A,A)P(A/M_A)+P(M_C/M_A,A)P(C/M_A)=\frac{1}{10}*\frac{10}{11} +1*\frac{1}{11} =\frac{2}{11}$
