Answer:
The lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.
Step-by-step explanation:
The Mom's plot is longer in ranges, therefore, she would have more variability than the dad.
The area of a sphere: A = 4.π.R²
A= 5541.77 → 5541.77 = 4.π.R²
R² = (5541.77)/(4.π)
R² = 441; → R =√441; R = 21 cm
Answer:
7
Step-by-step explanation:
let the no. be 'x'
By question,
2x-8=6
or, 2x =6+8
or,2x = 14
or,x = 7
therefore, the no. is 7.
Treat this like a slope formula. Y2-y1 divided by x2-x1.
Your y2 value is the second population
Y1= value of first population.
X2= second year they give
X1= first year they give.

Answer:
x=sqrt(3)/2 or -sqrt(3)/2
Step-by-step explanation:
(x,1/2) is on the unit circle at pi/6 and 5pi/6.
so x is either sqrt(3)/2 or -sqrt(3)/2
