Write (2 4) and (6 16) in the form y=mx+b

Lena [83]

Answer:

y = 3x-2

Step-by-step explanation:

We can find the slope using the formula

m = (y2-y1)/(x2-x1)

= (16-4)/(6-2)

=12/4

We then use the point slope form of a line

y-y1= m(x-x1)

y-4 = 3(x-2)

Distribute the 3

y-4= 3x-6

Add 4 to each side

y-4+4 = 3x-6+4

y = 3x-2

This is in slope intercept form

Students who attend Washington Middle School are either in seventh or eighth grade. At the end of the first semester 25% of the

Irina18 [472]

Answer:

There are 1240 students who attended Washington Middle School.

Step-by-step explanation:

Given:

Students who attend Washington Middle School are either in seventh or eighth grade.

At the end of the first semester 25% of the students at Washington Middle School were on the honor roll.

Seventh graders represented 60% of the students on the honor roll.

If 124 students on the honor roll were in eighth grade.

Now, to find the students attend Washington Middle School.

Let the total number of students be $x.$

So, the students at Washington Middle School were on the honor roll:

25% of $x$

$=\frac{25}{100} \times x$

$=\frac{25x}{100}$

$=\frac{x}{4}$

As, given seventh graders represented 60% of the students.

So, the students on the honor roll represented as seventh graders:

$60\%\ of\ \frac{x}{4}$

$=\frac{60}{100} \times \frac{x}{4}$

$=0.6\times \frac{x}{4}$

$=\frac{0.6x}{4}$

As, 124 students on the honor roll were in eighth graders.

Thus,

According to question:

$\frac{x}{4} -\frac{0.6x}{4} =124$

$\frac{x-0.6x}{4} =124$

$\frac{0.4x}{4} =124$

Multiplying both sides by 4 we get:

$0.4x=496$

Dividing both sides by 0.4 we get:

$x=1240.$

Therefore, there are 1240 students who attended Washington Middle School.

Elodia [21]

Answer:

The provided statement is True.

Step-by-step explanation:

Holding a variable constant implies that there are no kind of relationship between the variables and the treatments.

Holding a participant variable constant has the double advantage:

(1) preventing the variable from becoming a confounding variable

(2) reducing variance within groups.

A confounding variable effects both the dependent and the independent variable remarking a relationship between the two.

Variation within group implies the difference caused by the individual values of each group.

Thus, the provided statement is True.

Challenge A large university accepts 40% of the students who apply. Of the students the university accepts, 35% actually enroll.

Shkiper50 [21]

Answer:

2800 students would actually enroll.

Step-by-step explanation:

Of the 20,000 students who apply to a university, 40% are accepted.

It means:

20,000 × 40% = 20,000 × 40/100 = 8000 students are accepted

Of these, 35% enroll.

8000 × 35% = 8000 × 35/100 = 2800 students enroll

Therefore, 2800 students would actually enroll.
