slava [35]
Answer:
Mean: 3.5
Median: 3
Mode: 4
Range: 7
Step-by-step explanation:
As we know that volume is three dimensional so we will multiply width, length and depth
Now as we have to find the depth of the pool so
Volume= length*width*depth
depth=Volume/(length*width)
d=2500/(40*22)
d= 2500/880
depth=2.841ft
Answer:
Option (c) is correct.
Add a constant to a row does not involves while solving a system of equations using matrix.
Step-by-step explanation:
Given : solving a system of equations.
W have to choose from given options that can not be used on a matrix when solving a system of equations.
Since solving the system using matrix method involve
1) adding of rows,
2) multiplying a row by a constant.
3) interchange rows
But add a constant to a row does not involves while solving a system of equations using matrix.
Thus, Option (c) is correct.
Answer:
<h2>
x=1.8 cm</h2>
Step-by-step explanation:
(2x)²+(x+3)²=(2x+2.4)²
4x²+x²+6x+9=4x²+9.6x+5.76
5x²+6x+9-4x²-9.6x-5.76=0
x²-3.6x+3.24=0
(x-1.8) ²=0
x-1.8=0 => x=1.8 cm
Answer:
38 and 36 is equal to 74 so its 38 36
