g Determine the critical values for these tests of a population standard deviation. ​(a) A​ right-tailed test with 16 degrees of
Vladimir79 [104]

Answer:

Step-by-step explanation:

We are to find critical values for the test given

a) df =16: Alpha = 0.01  and right tailed

Critical value= 2.583

b) df = 23-1 = 22: alpha = 0.1 and left tailed

critical= -1.717

c)df=31-1 =30:  alpha =0.1:  two tailed

t =1.697

Critical values can be obtained from critical t tables.

Left tailed will have negative sign and right tailed positive

Use synthetic division to solve (4x^3-3x^2+5x+6)/(x+6).what is the quotient
ladessa [460]

Answer:

The quotient= 4x^2-27x+167.

Step-by-step explanation:

Given

Dividened= 4x^3-3x^2+5x+6

Divisor=x+6

In synthetic division : Put denomerator is equal to zero.

Put x+6=0

x=-6

Put -6 in division box as a divisor.

Coefficient of x^3=4

Coefficient of x^2=-3

Coefficient of x=5

Constant value=6

Put the coefficient of x^3,x^2,x and constant in descending order of power of x in  division problem.

Now ,bring the coefficient of x^3 is 4  straight down .

Now, multiply the numbe -6 in the division box with the number 4 brought down and put the result -24  below the number - 3 of next column.

By adding we get -27 and  write result in the bottom of row .

Again ,the number -6 multiply with -27 and put the result=162 below the number of next column.

By adding two number together we get 167 and put the result in the bottom of row.

Again, the number -6 in division box multiply with  the number 167 and put the result=1002 below the number of next column.

Adding two number together we get 1008 and write in the bottom of row.

Last number is remainder and then write the remainder  in fraction .

In quotient the power of x reduces by 1  from the numertor.

Hence, the quotient =4x^2-27x+167

Remainder=\frac{1008}{x+6}.
