Answer:


Step-by-step explanation:

In the first part the given polynomial is 3x^{3}-2x^{2}+x-1, we have to divide this polynomial by (x-1) using synthetic division.

Here are the steps of synthetic division

Step 1: Set up the synthetic division table in which the coefficients are written in descending power of x.

Step 2: Drop down the leading coefficient i.e the coefficient of highest power of x to the bottom row.

Step 3:  Multiply a by the value just written on the bottom row and write this value just down of the number written next of leading coefficient.  Here, a is 1(taken from divisor)

Step 4:  Add the column made in step 3.  Repeat these steps until the last column reached.

In the second part,

It is given that divisor polynomial is the factor of given polynomial then we have to tell the remainder which is 0 because if divisor polynomial is the factor the it will completely divide the given polynomial which gives remainder 0.

In the third part,

Given when one uses the synthetic division to divide by (x-3) then what number is used to multiply each term that is dropped down or added.

As explained the steps of synthetic division in first part

x-3=0 ⇒ x=3 which is a

In step 3, Multiply a by the value just written on the bottom row and write this value just down of the number written next of leading coefficient. So, 3 is multiplied.

As explained in Step 2: Drop down the leading coefficient i.e the coefficient of highest power of x to the bottom row.

The columns which is formed by above steps are added.

igor_vitrenko [27]

Answer:

Step-by-step explanation:

find the difference between the two angles first:

155-65=90 degrees

d is the distance d:

d^2=a^2+b^2-2ab cos(90)

d^2=10^2+8^2-2(10)(8)cos(90)

d^2=164

d=√164=12.81

the bearing of R from P to the nearest degree:

180-155=35 degrees

2x + 3 – 4 = 5x - 7 <br><br><br><br> 2 <br><br> -2 <br><br> - 9 <br><br> 9
Marysya12 [62]

2x + 3 - 4 = 5x - 7

=> 2x + 3 - 4 + 7 = 5x

=> 3 - 4 + 7 = 5x - 2x

=> 3 - 4 + 7 = 3x

=> -1 + 7 = 3x

=> 6 = 3x

=> 6/3 = x

=> 2 = x

Joe has 10 marbles. Ken has fewer marbles than Joe. Which inequality represents the
Colt1911 [192]

Answer:

m<10

Step-by-step explanation:

Inequality is used to show comparison between two values. It helps to determine which is

• Greater than (>),

• Less than (<),

• Equal to(=),

• Not equal to,

• Greater than or equal to,

• Less than or equal to.

• Greater than is used when one value is more than the other.

• Less than is used when a value is less or smaller than another value.

• Equal to is used when both values are the same.

• Not Equal to is used when both values are not the same

Let Ken marbles= m

Remember that Ken's marbles is fewer than Joe's, that is less than Joe's marbles.

The inequality will be

m<10

romanna [79]

Answer: The p-value is 0.154.

Step-by-step explanation:

Since we have given that

We claim that

Null hypothesis :

H_0:\mu=20

Alternate hypothesis :

H_1:\mu

Population mean = 20 hours

Sample mean = 18.5 hours

Sample standard deviation = 4.3 hours

Sample size n = 35

So, test statistic would be

z=\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{18.5-20}{\dfrac{4.3}{\sqrt{35}}}\\\\z=\dfrac{-1.5}{0.726}\\\\z=-2.066

So, the  p value would be 0.154.

Hence, the p-value is 0.154.
