The percentage of children enrolled in 2011 is 64 %.
<u>Step-by-step explanation:</u>
From the given data we are given with set of x values an y values.
Moreover, the years were given with differences of 2 years.
So let us consider the years 2008 as 0, 2010 as 2, 2012 as 4 and 2014 as 6.
Using interpolation we have to find the percentage of children enrolled in 2011. i.e. 3.
Interpolation is given by the formula,
Let us choose the points (2, 63.7) and (4, 64.3), since 3 is between 2 and 4.
Substitute the values in the formula.
.
.
y-63.7=0.3.
y= 63.7+0.3
y= 64.
The percentage of children enrolled in 2011 is 64 %.
Answer:
16
Step-by-step explanation:
Fractions which use models and number lines are the same because they generally tell the same ideas and math concepts of adding, multiplying, subtracting, and dividing. They are only different in terms of association because with models we use our visual sensory to interpret and analyze the data given to us, while, the number line is tapping our logical brain.
Let the two numbers be x and y
x + y = 18 . . . . . . . . (1)
x/y = 17 . . . . . . . . (2)
from (2): x = 17y
substituting for x in (1), gives
17y + y = 18
18y = 18
y = 18/18 = 1
x = 17y = 17(1) = 17
Therefore the two numbers are: 1 and 17
Step-by-step explanation:
Given
c² = a² + b²
Making a² subject then
a² = c² - b²
