Your process is close!

Since 3/10 and 4/15 is the amount you missed you have to subtract that by 1.

1 - 0.3 = 0.70
1 - 0.26 = 0.74

So, you scored higher on the math quiz.

Hope this helps!

What is the equation of a line that is perpendicular to 2x+y=-4 and passes through the point (2, -8)?

ahrayia [7]

2x + y = -4
y = -2x - 4
differentiate:
y' = -2

m=-2 perpendicular = -1/m = -1/-2 = 0.5, x=2 y=-8

y=mx+c
-8=0.5(2) + c
-8 = 1 + c
-9 = c

y = .5x - 9

OR you can use y-y_1 = m(x - x_1), where x_1 = 2, y_1 = -8, m = 0.5
y - -8 = 0.5(x - 2)
y + 8 = 0.5x - 1
y = 0.5x - 9

same answer either way

Number of data values: 1007

kogti [31]

Answer:

The arithmetic mean is 10.9

Step-by-step explanation:

In this question, we are tasked with calculating the arithmetic mean using the information given.

The arithmetic mean or otherwise called the average is the sum of all the values in a given set divided by the number of elements or count of the elements in that particular data set

Mathematically, the arithmetic mean can be found by dividing the sum of the data values by the number of data values.

In equation form, we have $Arithmetic -mean = \frac{sum of data values}{number of data values}$

Inserting the values, we have Arithmetic mean = 10998/1007 = 10.92 which is 10.9 to the nearest tenth
