Answer:

n=30

Step-by-step explanation:

solve by simplifying both of the equations , the isolating the variable

Reduce the fraction with 9  27/36 divide top and bottom by 9 = 3/4

n/40=3/4   cross multiplication 4n = 120 ( divide both sides by 4 )

n=30

Write an equation of the line that passes through (2,5) and is parallel to the line 2y = 3x + 10.
Advocard [28]

Answer:

y = 3/2x - 8  hope I helped

Step-by-step explanation:

To find the equation of a line, we need a point and a slope. We're given a point, and we can easily get the slope. First let's solve 2y = 3x + 10 for y so we can get the slope (recall that y = mx + b is the slope-intercept form, and m is your slope).

2y = 3x + 10  --> almost there already, just divide everything by 2 to get y by itself.

y = 3/2x + 5 --> now you have it in the y=mx + b form, so your slope is 3/2

They asked for the parallel line, remember parallel lines have the same slope, therefore you use the same slope.

Now we know that our slope is m = 3/2 and our point is (2, -5)

You can always find the equation of a line using the Point-Slope Formula:

y - y1 = m(x - x1)    --> our x1 is 2 and our y1 is -5, and slope is 3/2

y - (-5) = 3/2(x - 2)   --> Be careful when you have minus a negative number, like we do here. It becomes:

y + 5 = 3/2(x - 2)  --> now distribute the 3/2

y + 5 = 3/2x - 6/2

y + 5 = 3/2x - 3  --> now we can subtract 5 from both sides to get it into slope intercept form.

y = 3/2x - 8  --> This is the equation of a line that is parallel to 2y=3x+10 & passes through (2, -5)

Suppose that P(A) = 0.97. Which of the following is the best interpretation of this statement?
storchak [24]

We have that This equation simply state that P as a Function of A is equal to 0.97

From the question we are told that

P(A) = 0.97.

Generally

This equation simply state that P as a Function of A is equal to 0.97

i.e P is a Constant equation and A is a variable that changes P to 0.97

On a test, the marks for ten students are: 2 students, 85%; 4 students, 78%; 3
anzhelika [568]

Answer:

77.2%

Step-by-step explanation:

The average formula is:

Average = \frac{Sum/of/all/numbers}{How/many/numbers/there/are}

Let's first find the sum of all the numbers (remember sum means to add):

(2)(85) + (4)(78) + (3)(66) + 92 = ?

170 + 312 + 198 + 92 = 772

There are marks for 10 students so that is what goes at the bottom (10 students, 10 test scores)

Plug both things into the equation:

Average = \frac{772}{10} \\= 77.2

Therefore, the average mark on the test was 77.2%
