Answer:
Step-by-step explanation:
Givens
P is (2,8)
Q is (-6,-6)
Equation
Midpoint = (x1 + x2)/2,(y1 + y2)/2
Solution
x1 = - 6
x2 = 2
y1 = -6
y2 = 8
M = (-6 + 2)/2, (-6+8)/2
M = -4/2, 2/2
M = -2 , 1
Just to make sure that you know that the answer is reasonable, I've put the midpoint (-2,1) on a graph with the two endpoints. You could print the points out and check it with a ruler.
Answer:
125.7cm²
Step-by-step explanation:
Given parameters:
Slant height, L = 6cm
Base radius = 4cm
Unknown:
Total surface area = ?
Solution:
To find the total surface area, we use the expression;
Surface area = r² +
rL
Now insert the parameters and solve
Surface area = r(r + L )
Surface area = x 4 (4 + 6) = 3.142 x 4 x 10 = 125.7cm²
Answer:
5.21-th
Step-by-step explanation:
Mean pregnancy time (μ) = 266 days
Standard deviation (σ) = 16 days
The z-score, for any given pregnancy period 'X' is determined by:
For X = 240 days:
According to a z-score table, a score of -1.625 is equivalent to the 5.21-th percentile of a normal distribution
