Given:
Total number of marbles = 15
Probability of randomly selecting a green marble =
.
Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble =
.
To find:
The number of blue marbles.
Solution:
Let the number of blue marbles be x.


It is given that,

Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is
. So,



Multiply both sides by 75.



Therefore, the number of blue marbles in the bag is 6.
A kite is a quadrilateral.
So the correct answer is A.

Answer:
5/2
Step-by-step explanation:
Answer:
The graph g(x) is the graph f(x) vertically stretched by a factor of 7.
Step-by-step explanation:
Quadratic Equation: f(x) = a(bx - h)² + k
Since we are modifying the variable <em>a</em>, we are dealing with vertical stretch (a > 1) or vertical shrink (a < 1). Since a > 1 (7 > 1), we are dealing with a vertical stretch by a factor of 7.
Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)
