Answer:

Option Negative 1 and four-fifths is correct

That is x=-1\frac{1}{5}

Step-by-step explanation:

Given problem is Negative start fraction 2 over 9 end fraction x=two-fifths

Given equation  can be written as -\frac{2}{9}x=\frac{2}{5}

To find the value of x in the given equation :

-\frac{2}{9}x=\frac{2}{5}

Mutliply by \frac{9}{2} on both sides we have

\frac{2x}{9}\times(\frac{9}{2})=\frac{2}{5}\times(\frac{9}{2})

-x=\frac{9}{5}

x=\frac{-9}{5}

x=-1\frac{1}{5}

therefore the value of x is -1\frac{1}{5}

Option Negative 1 and four-fifths is correct

That is x=-1\frac{1}{5}

4x plus 5 equals 3x plus 10
AleksandrR [38]

Answer:

x=5

Step-by-step explanation:

4x+5=3x+10

All x values must go on the right so subtract 3x from both sides

4x+5=3x+10

-3x -3x

which gets you

x+5=10

Now subtract 5 from both sides to get the value of x

x+5=10

-5 -5

And you get

x=5

Use the fundamental identities to verify
Vilka [71]

Answer:

see below

Step-by-step explanation:

6 cot ^2 (y) ( sec^2 (y) -1) = 6

We know that ( sec^2 (y) -1) = tan ^2(y)

6 cot ^2 (y) tan ^2 (y) = 6

We know cot = cos/ sin   and tan = sin / cos

6 cos/ sin ^2 (y) sin/cos ^2 (y) = 6

6 ( 1) = 6

6=6

Select the correct answer. Which pair of statements correctly compares the two data sets? A. The difference of the means is 1. T
Readme [11.4K]

Answer:

For this case since the p value is higher than the significance level we can FAIL to reject the null hypothesis and we can conclude that the true means are NOT significantly different at 10% of significance.

Step-by-step explanation:

Information provided

represent the mean for sample 1  

represent the mean for sample 2  

represent the sample standard deviation for 1  

represent the sample standard deviation for 2  

sample size for the group 2  

sample size for the group 2  

Significance level provided

t would represent the statistic

Hypothesis to test

We want to verify if the true means for this case are significantly different, the system of hypothesis would be:  

Null hypothesis:  

Alternative hypothesis:  

The statistic is given by:

(1)  

And the degrees of freedom are given by    

Replacing the info given we got:

 

The degreess of freedom are given by:

Now we can calculate the p value with the following probability:

 

For this case since the p value is higher than the significance level we can FAIL to reject the null hypothesis and we can conclude that the true means are NOT significantly different at 10% of significance.
