If the decimal can't be written into a ratio, then it is not rational.
Answer:
That is 4
Step-by-step explanation: First you need to substitute 9 in for m. Then multiply 4 x 9 to get 36. Then the square root of 36 is 6. Lastly 6-2 equals 4.
Answer:
P( 44 < X < 56 ) = 0.12
Step-by-step explanation:
Number of seconds one gets to solve the puzzle ( X )
E( X ) = 100 + 0 ) / 2 = 50
Var ( X ) = 833.3333
бx = √833.3333 = 28.868
<u>Determine The approximate probability </u>
P( 44 < X < 56 ) = Δ time given / number of players selected
P( 44 < X < 56 ) = (56 - 44) / 100
= 12 / 100 = 0.12
Answer:
Cost of 15 oranges=Rs. 40

The equation is x^4 - 4x^3 + 3x^2 = 0.
You can simplify the terms as so:
x^2(x^2-4x+3) = 0
The equation above now contains x^2 and a quadratic function. A potential solution is x = 0 because x^2 = (0)^2 = 0.
Regarding the quadratic part of the equation,
x^2 - 4x + 3 = 0
(x+4)(x-1) = 0
When x = -4 or 1, the entire equation equals zero.
Therefore, the zeroes of the function are -4, 0, and 1.
