Answer:
The radius of the circle is 3 units
The center of the circle lies on the x-axis.
The radius of this circle is the same as the radius of the circle whose equation is x^2 + y^2 = 9
Step-by-step explanation:
I dont know if m2 is the variable or its suppose to be m(2)
Answer:
The standard deviation of this probability distribution is 1.2.
Step-by-step explanation:
We have that:
P(X = 0) = 0.25
P(X = 1) = 0.3
P(X = 2) = 0.1
P(X = 3) = 0.35
Mean:
Each value multiplied by its probability. So
Variance:
Sum of the squares of the values subtracted from the mean, and multiplied by its probability.
Standard deviation:
Square root of the variance. So
The standard deviation of this probability distribution is 1.2.
we know that
the ratio of the perimeters is equals to the scale factor
scale factor=5/8
scale factor=measure smaller square/measure larger square
let
smaller square=first square
larger square=second square
area smaller square=[scale factor]²*area larger square
so
area larger square=area smaller square/[scale factor]²
scale factor=5/8
area smaller square=225 m²
area larger square=225/[5/8]²----> 225/(25/64)-- > 225*(64/25)-----
> 576 m²
the answer is
the area of the second square (larger square) is 576
m²
