A class of 40 students elected a class president. There were 12 votes for Candidate A, and 18 votes for Candidate B.

Helen [10]

Hey there, Bulgogi!

The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.

So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]

Once put into a fraction, we will get $\frac{12}{12+18}$ which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.

A study of class attendance and grades among first-year students at a state university showed that, in general, students who mis

Answer:

the numerical value of the correlation between percent of classes attended and grade index is r = 0.4

Step-by-step explanation:

Given the data in the question;

we know that;

the coefficient of determination is r²

while the correlation coefficient is defined as r = √(r²)

The coefficient of determination tells us the percentage of the variation in y by the corresponding variation in x.

Now, given that class attendance explained 16% of the variation in grade index among the students.

coefficient of determination is r² = 16%

The correlation coefficient between percent of classes attended and grade index will be;

r = √(r²)

r = √( 16% )

r = √( 0.16 )

r = 0.4

Therefore, the numerical value of the correlation between percent of classes attended and grade index is r = 0.4

Its only one math question show right steps then get brainliest and right answer ofc

valkas [14]

Step-by-step explanation:

equation.

2(m+10)=4(m−15)

(2)(m)+(2)(10)=(4)(m)+(4)(−15)(Distribute)

2m+20=4m+−60

2m+20=4m−60

Step 2: Subtract 4m from both sides.

2m+20−4m=4m−60−4m

−2m+20=−60

Step 3: Subtract 20 from both sides.

−2m+20−20=−60−20

−2m=−80

Step 4: Divide both sides by -2.

−2m−/2=−80/−2

m=40
