The choice a could not be true because the value of f(1) is
already equal to 5. Therefore, the value of f(1) cannot be 1. This is one of
the properties of a function that for every value of x, there should be only
one corresponding value of y.
Answer:
Step-by-step explanation:
By using regression line calculator,
Equation of the regression line from the data given,
y = -0.38993x + 26.95184
Here, y = weekly hours of sport
x = Time to run
For x = 50 minutes,
y = -0.38993(50) + 26.95184
= 7.45534
≈ 8
Since, slope of the given regression line is negative, correlation will be negative (n).
Answer:
x = 9
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is
Parallel to the third side
then the 2 angles are same- side interior angles and sum to 180° , that is
16x - 33 + 8x - 3 = 180
24x - 36 = 180 ( add 36 to both sides )
24x = 216 ( divide both sides by 24 )
x = 9
If 60% of the painters is 12, then 10% of the painters is 2, and therefore there are 20 painters.
