What is the value of f(-5) in the function f(x)=6x-3?

When asking for f(-5) or any other number, they are asking you to plug in that number for x.

So, f(-5) = 6(-5) - 3
f(-5) = -30 - 3
f(-5) = -33

F(-5)=6x-3

F(-5)=6(-5)-3

F(-5)=-30-3

= +33

A survey conducted by a leading HMO found that of 2000 women, 340 were heavy smokers and 25 had emphysema. Of those who had emph

Answer:

The events being a heavy smoker and having emphysema are not independent.

Step-by-step explanation:

We are given the following in the question:

Number of women = 2000

Number of heavy smoker = 340

Number of women who has emphysema = 25

Number of women who has emphysema and are heavy smoker = 21

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

P(Smoker) =

$P(S) = \dfrac{340}{2000}=0.17$

P(emphysema) =

$P(E) = \dfrac{25}{2000}= 0.0125$

P(Smoker and emphysema) =

$P(S\cap E) = \dfrac{21}{2000} = 0.0105$

Two events A and B are said to be independent if

$P(A\cap B)=P(A)\times P(B)$

Checking conditions for independence:

$P(S)\times P(E) = 0.17\times 0.0125=0.002125\\P(S)\times P(E) \neq 0.0105\\P(S)\times P(E)\neq P(S\cap E)$

Thus, the events being a heavy smoker and having emphysema are not independent.

Answer:

Step-by-step explanation:

an aquarium is in the shape of a cuboid

the depth can be determined from the volume of a cuboid

volume = length x depth x height

11.96 = 2.5 x 1.1 x depth

depth = 11.96 / (2.5 x 1.1 )

depth = 4.3 feet = 4 (to the nearest whole number)

To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
