Answer:

yes

Step-by-step explanation:

8+4=12>10.5

10.5+4>8

and 10.5+8>4

again

10.5-8=1.5<4

10.5-4=5.5<8

8-4=4<10.5

sum of two sides> third side.

and

difference of any two sides <third side.

The graph of the step function g(x) = –⌊x⌋ + 3 is shown. What is the domain of g(x)? {x| x is a real number} {x| x is an integer

allsm [11]

Answer:

Option A is correct.

The domain of the g(x) is {x | x is a real number}

Step-by-step explanation:

The graph of the step function: g(x)= $-\left \lfloor x \right \rfloor +3$

Floor function is defined as the function that gives the highest integer less than or equal to x.

The graph of function: g(x)= $-\left \lfloor x \right \rfloor +3$ where x is the independent variable as shown below;

Domain of any function is the complete set of possible values of the independent variable

Therefore, the domain of the function g(x) is the set of all real numbers or we can represent this as {x | x is a real number}.

Find the distance between the points c ( 6, 5) and D(-3, 1),

svet-max [94.6K]

Answer:

see explanation

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (6, 5) and (x₂, y₂ ) = (- 3, 1)

d = $\sqrt{(-3-6)^2+(1-5)^2}$

= $\sqrt{(-9)^2+(-4)^2}$

= $\sqrt{81+16}$

= $\sqrt{97}$ ≈ 9.85 ( to 2 dec. places )

A survey is being conducted in a county where 62% of the voters are Democrats and 38% are Republican. (a) What is the probabilit

Inessa05 [86]

Answer:

0.3844 = 38.44% probability that two independently surveyed voters would both be Democrats

Step-by-step explanation:

For each voter, there are only two possible outcomes. Either the voter is a Democrat, or he is not. The probability of the voter being a Democrat is independent of other voters. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

62% of the voters are Democrats

This means that $p = 0.62$

(a) What is the probability that two independently surveyed voters would both be Democrats?

This is P(X = 2) when n = 2. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 2) = C_{2,2}.(0.62)^{2}.(0.38)^{0} = 0.3844$

0.3844 = 38.44% probability that two independently surveyed voters would both be Democrats

The human population of the earth can be modeled by p(T)=3.1(1.016)^t , where T represents the number of year since 1963 , and p

Mkey [24]

Answer:

See below

Step-by-step explanation:

Given function:

p(t)=3.1(1.016)^t

The base of the growth rate is:

1.016 = 1 + 0.016

It represent a 1.6% of growth per year.

Increasing

p(55) = 7.42 means:

55 years after 1963, in the year 2018, the population of Earth is 7.42 billions
