Answer:

a.f(-1)=2

b.f(3)=6

c. f(x-1)=x+2

Step-by-step explanation:

We are given that f(x)=x+1+2

a.We have to find the value of f(-1)

Substitute the value of x in the given function

Then, we get

f(-1)=-1+1+2=2

f(-1)=2

b.We have to find the value of f(3)

Substitute x=3 then we get

f(3)=3+1+2=6

f(3)=6

c.We have to find the value of f(x-1)

Replace x by x-1 then we get

f(x-1)=x-1+1+2=x+2

Hence, f(x-1)=x+2

A real estate agent wants to know how many owners of homes worth over​ $1,000,000 might be considering putting their home on the
JulsSmile [24]

Answer:

NO

Step-by-step explanation:

The changeability of a sampling distribution is measured by its variance or its standard deviation. The changeability of a sampling distribution depends on three factors:

  1. N: The number of observations in the population.
  2. n: The number of observations in the sample.
  3. The way that the random sample is chosen.

We know the following about the sampling distribution of the mean. The mean of the sampling distribution (μ_x) is equal to the mean of the population (μ). And the standard error of the sampling distribution (σ_x) is determined by the standard deviation of the population (σ), the population size (N), and the sample size (n). That is

μ_x=p

σ_x== [ σ / sqrt(n) ] * sqrt[ (N - n ) / (N - 1) ]

In the standard error formula, the factor sqrt[ (N - n ) / (N - 1) ] is called the finite population correction. When the population size is very large relative to the sample size, the finite population correction is approximately equal to one; and the standard error formula can be approximated by:

σ_x = σ / sqrt(n).

What is the equation of a line, in general form, that passes through point (1, -2) and has a slope of 1/3. 1.x - 3 y - 7 = 2.x -
Nutka1998 [239]

Answer:

x- 3y - 7=0

Step-by-step explanation:

the line in the slope-intercept form:

  • y= mx+b

m= 1/3 and point given (1, -2) by using which we find y-intercept:

  • b= y-1/3x
  • b= -2- 1/3*1= - 7/3
  • y= 1/3x- 7/3

General form of a line is: ax+by+c= 0

converting:

  • y= 1/3x- 7/3  ⇒  3y= x- 7  ⇒  x- 3y - 7=0

a circular fountain has a radius of 9.4 feet. find its diameter and circumference to the nearest tenth.
pickupchik [31]

Radius = r

Diameter : D = r*2

Circumference : C = 2πr

π = 3.14 rounded

9.4*2 =18.8

2(3.14)9.4

6.28*9.4= 59.03200

Diameter = 18.8

Circumference = 59.03200
