Answer:
82.49 percent were at least high school graduates.
Step-by-step explanation:
We have been given that at 1950 x=0
and at 1960 x=10
And following this pattern at 2000 x=50
So, we have coordinates:
(0,34.7) and (50,87.8) for two point form we will find a function:
Using:![y-y_1=\frac{y_2-y_1}{x_2-x_1}\cdot (x-x_1)](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5Ccdot%20%28x-x_1%29)
Substituting the values in the formula we get:
![y-34.7=\frac{87.8-34.7}{50-0}(x-0)](https://tex.z-dn.net/?f=y-34.7%3D%5Cfrac%7B87.8-34.7%7D%7B50-0%7D%28x-0%29)
![y-34.7=1.062(x)](https://tex.z-dn.net/?f=y-34.7%3D1.062%28x%29)
y=1.062 x+34.7 is the linear function
(b) Now, we need to find the value at x= 1995 which will be equal to 45 according to the pattern followed
Put x=1995 in the function above we get:
y =1.062(45)+34.7
y=82.49 percent were at least high school graduates.
C 1:3 it you multiply both numbers by 2 you will have 2:6. 1:3 is just simplified
Answer:
D
Step-by-step explanation:
I'm not that sure but 2x9-8 = 10
Answer:
11.183 cm and 22.366 cm
Step-by-step explanation:
Lets call the 25 cm hypotenuse C and the other sides A and B.
B=2A
The Pythagorean theorem states that C^2=A^2+B^2 so:
25^2=A^2+B^2
substitute for B
25^2=A^2+(2A)^2
625=A^2+4A^2
625=5A^2
125=A^2
A=11.183 cm
B=22.366 cm
