-3/4 + (-3/4)
$( - 3)/(4) + ( - 3)/(4)$

Answers

Answer 1

Answer:

Firstly, since these two fractions have the same denominator, add the numerators up: $(-6)/(4)$

While it appears that the answer is -6/4, you can further simplify it by dividing the numerator and denominator by 2: $-(6)/(4)/(2)/(2)=-(3)/(2)$

Your answer is $-(3)/(2)$

Sean's mom asks him how long his homework will take. He tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. All together, his homework will take h minutes. Write an equation for the number of minutes Sean's homework will take h, if his math problems take m minutes

Answers

Answer: The required equation is $h=25+m.$

Step-by-step explanation: Given that Sean's mom asks him how long his homework will take.

He tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. All together, his homework will take h minutes.

We are to write an equation for the number of minutes Sean's homework will take h, if his math problems take m minutes.

Since Sean needs to read for 25 minutes and do some math problem for m minutes, so total time that Sean will take will be

$25+m.$

Also, since Sean takes h minutes altogether to complete his homework, so the equation is written as

$25+m=h\n\n\Rightarrow h=25+m.$

Thus, the required equation is $h=25+m.$

Answer:

h=25+m

If it is 10;25 p.m. what time was it 11 hours and 55 minutes before that?

Answers

Answer:

10:30 am

Step-by-step explanation:

First we must convert the 10:25 pm to the 24 hour clock so we wont have negative results. To do this we add 12 hours to the given time (because it is between 1 pm and 11:59 pm)

10:25 hours+12 hours=22:25 hours

to this 22:25 hours we will substract 11:55 minutes to know what time was before that time passed like this:

-First we substract the minutes:

25-55=-30

we obtain a negative result, when this happens we add 60 to the first value (25)

85-55=30 (Minutes)

and substract 1 from the first value of the hours so we wont have 22 but 21. And we substract normally now having the minutes ready

21-11=10( Hours)

The time was 10:30 am

If it is 10;25 p.m. what time was it 11 hours and 55 minutes before 10:30 a.m.1

Which statement is true regarding the traits of scatterplots

Answers

Here are the choices

The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with positive correlation can have either weak correlation or strong correlation.

The slope of a line is independent of whether the correlation of a scatterplot has positive or negative correlation. A scatterplot with a negative slope can have either positive correlation or negative correlation.

The nonlinear association of a scatterplot depends on whether it has a weak or strong correlation. A scatterplot with nonlinear association will have a strong correlation.

The nonlinear association of a scatterplot depends on whether it has a positive or negative correlation. A scatterplot with nonlinear correlation will have a negative correlation.

It's a, because if it is positive, it can either be one skinny line, or one thick fat confusing line. Positive isn't perfect.

The statement first "The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative is true.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

The correlation between the two variables, the explanatory variable and response variable can have either a negative correlation or a positive correlation depending on the slope of the regression line.

When the dots are along the regression line we can say the correlation is strong.

If the dots are not along the regression line the correlation may have a weak correlation.

Thus, the statement first "The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with a positive correlation can have either a weak correlation or a strong correlation" is true.
