Vertically organize the problems
  (         -4x^2-2x-1)
- ( 3x^3             +2)
Eliminate the minus sign by multiplying by -1
-1(3x^3             +2)
This is the new problem
   (        -4x^2-2x-1)
+ (-3x^3             -2)

Simplify any terms, then this is the answer
-3x^3-4x^2-2x-3
This is how I got it, but if there are any other answers, feel free to share

Do male and female servers work the same number of hours? A sample of 25 female servers worked an average of 26 hours per week,
Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

Given that

Group   Group One     Group Two  

Mean       26.00 23.00

SD                 2.00 4.00

SEM         0.40 1.21

N                     25     11    

where group I represents female servers and group II male servers.

We have to calculate confidence interval for 90% for difference in means

The mean of Group One minus Group Two equals 3.00

df = 34  

 standard error of difference = 0.993

t critical = 2.034 for 90% df 34

Hence confid. interval at 90%

=Mean diff ±2.034 * std error of diff

= (0.98, 5.02)

What is the answer to 0 > 3x - 3 - 6?
swat32

Answer:

3 = x

Step-by-step explanation:

0 > 3x - 3 - 6

You want to group up the -3 and -6 first

0 > 3x - 9

Then you want to add 9 to each side to cancel out the negative 9 on one side.

0 > 3x - 9

+9        +9

9 > 3x

Now you just divide by 3 on each side

\frac{9 = 3x}{3}

3 = x

A research team hypothesizes that setting weekly scheduled online interactions versus not setting such interactions can boost th
leva [86]

Answer:

Type I error occurs when the null hypothesis, H0, is rejected, although it is true.

Here the null hypothesis, H0 is:

H0: Setting weekly scheduled online interactions will boost the well being of people who are living on their own during the stay at home order.

a) A Type I error would be committed if the researchers conclude that setting weekly scheduled online interactions will not boost the well being of people who are living on their own during the stay at home order, but in reality it will

b) Two factors affecting type I error:

1) When the sample size, n, is too large it increases the chances of a type I error. Thus, a sample size should be small to decrease type I error.

2)A smaller level of significance should be used to decrease type I error. When a larger level of significance is used it increases type I error.
