Answer:
x=5
Step-by-step explanation:
if 3+5 equals 8 then 3 plus x would be 5
The variance of a constant is zero. Rule 2. Adding a constant value, c, to a random variable does not change the variance, because the expectation (mean) increases by the same amount. ... Multiplying a random variable by a constant increases the variance by the square of the constant.
Answer:
count them: 12
Step-by-step explanation:
All of the edges are shown in the figure. 9 are visible, and 3 are hidden, as indicated by their being a lighter gray (dotted). You can answer this question by counting the edges.
The total number of edges that a cuboid has is 12.
Answer:
24.2 centimeters
Step-by-step explanation:
for height = f(time)
let x be the value of the height at 28hours
solving linearly
(28 - 15)/(32 - 15) = (x - 19)/(12.2 - 19)
solving we have
13/17 = (x - 19)/6.8
0.7647 = (x - 19)/6.8
cross multiplying,
x - 19 = 5.2
x = 5.2 + 19 = 24.2centimetres
Slope is 3 so the equation is y-2=3(x-1) in point slope form as y-y1 =m (x-x1)
