Answer:

24 girls and 16 boys

Step-by-step explanation:

If there's a total of 40 students, you can divide that equally by the total amount of boy and girls. 3 girl units + 2 boy units (each unit is equivalent) is 5 total units. 40 ÷ 5 = 8 total people per unit

8 people per unit x 3 female units is 24 total females

8 people per unit x 2 male units is 16 total males

The equation used to predict college gpa (range 0-4.0) is modifyingabove y with caret equals 0.22 plus 0.51 x 1 plus 0.002 x 2y

posledela

The college GPA for a high school GPA of 3.1 and a college board score of 500 will be 2.801

The equation to predict college GPA is :

$y= 0.22+0.51x1+0.002x2$

where x1 is high school GPA and x2 is college board score.

According to the question, here x1= 3.1 and x2= 500

So, we will plug the values of x1 and x2 into the above equation..

$y= 0.22+(0.51*3.1)+(0.002*500) \\ \\ y=0.22+1.581 +1\\ \\ y=2.801$

So, the college GPA for a high school GPA of 3.1 and a college board score of 500 is 2.801

What is the thirty-second term of the arithmetic sequence -12, -7, -2, 3, ... ? Show your work.

anzhelika [568]

The thirty-second term is 143

Further explanation:

As it is already given that the given sequence is an arithmetic sequence

We have to find the common difference first

So,

$a_1=-12\\a_2=-7\\a_3=-2\\a_4=3$

$d=a_2-a_1=-7-(-12)=-7+12=5\\a_3-a_2=-2-(-7)=-2+7=5$

The common difference is 5.

And first term is -12

The explicit formula for arithmetic sequence is:

$a_n=a_1+(n-1)d\\Here,\\a_n\ is\ nth\ term\\a_1\ is\ first\ term\\d\ is\ common\ difference$

Putting the values in the formula

$a_n=-12+(n-1)(5)\\a_n=-12+5n-5\\a_n=-17+5n$

Putting n=32 in explicit formula

$a_{32}=-17+5(32)\\=-17+160\\=143$

The thirty-second term is 143
