Answer:

f(6) = 12

Step-by-step explanation:

We are given the following function:

[tex]f(x) = x^2 - 5x + 6[/tex]

Evaluate the function f(6).

This is [tex]f(x)[/tex] when [tex]x = 6[/tex]. So

[tex]f(6) = 6^2 - 5(6) + 6 = 36 - 30 + 6 = 12[/tex]

f(6) = 12 is the answer.

Answer:

A = $2130.49

Step-by-step explanation:

Given the following data;

Time, t = 5 years

Interest rate, r = 8%

Principal = $1450

To find the future value, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{100})^{t}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 1450(1 + \frac{8}{100})^{5}[/tex]

[tex] A = 1450(1 + 0.08)^{5}[/tex]

[tex] A = 1450(1.08)^{5}[/tex]

[tex] A = 1450 * 1.4693 [/tex]

A = $2130.49

Answer:

  40 units

Step-by-step explanation:

The slanted side is the hypotenuse of a triangle that is 8 units high and 6 units wide. Its length can be found from the Pythagorean theorem:

  d² = 6² + 8² = 100

  d = √100 = 10

The perimeter is the sum of side lengths. Those lengths can be found by counting grid squares. Clockwise from the upper left corner, the sum of side lengths is ...

  P = 8 + 10 + 14 + 8

  P = 40 . . . units

Answer:

CI 90 %  =  [  0,165  ;  0,235 ]

Lower limit     0,165

upper limit      0,235

Step-by-step explanation:

Sample information:

sample size    n  =  225

number of dissatisfied  individuals   x  =  45

p = 45/225

p = 0,2    and  q =  1 -  p   q  =  1  -  0,2   q  =  0,8

p*n = 0,2*225   =  45    and   q*n   =  0,8*225  =  180

p*n  and q*n  big enough to use the approximation of binomial distribution to normal distribution

90 % of Confidence Interval   then a significance level is  α  = 10%

α  =  0,1 in z table we get z(c) for that significance level

z(c) = 1,28

CI 90 %   =  [  p  ±  z(c)*√(p*q)/n ]

z(c) * √(p*q)/n    =  1,28 *  √ ( 0,2*0,8)/225

z(c) * √(p*q)/n    =  1,28 * 0,027

z(c) * √(p*q)/n    =  0,035

CI 90 %  =  [  0,2  ±  0,035 ]

CI 90 %  =  [  0,165  ;  0,235 ]

Lower limit     0,165

upper limit      0,235

Systematic sampling is a probability sampling approach in which researchers choose individuals of the population at a predetermined regular interval. The correct option is C, a systematic sample.

Systematic sampling is a probability sampling approach in which researchers choose individuals of the population at a predetermined regular interval (or k).

If the population order is random or random-like (e.g., alphabetical), this approach will yield a representative sample from which inferences about the population can be drawn.

Given that At a party there are 30 students over the age of 18 and 20 students under 18. You randomly choose 3 students over 18 and 2 students under 18 to interview.

Because you cannot get a list of your people in advance. As a result, the entire instance presented to us is an example of systematic sampling.

Answer:

The future value is $3793.776

Step-by-step explanation:

Given

[tex]PV = 2940[/tex] --- present value

[tex]r = 3.2\%[/tex] --- rate

[tex]t = 8[/tex] --- time

[tex]n = 4[/tex] --- quarterly
