Answer:
Malik substituted 60 for y instead of x.
Step-by-step explanation:
According to the given situation the computation of error that Malik make first when solving the equation is shown below:-
First, we will find the value of x
x = 625
Now, we have
we will solve the above equation, to find the value of y
24 - 4y = 10
4y = 24 - 10
4y = 14
So, from the above calculation, the correct option is
Malik substituted 60 for y instead of x.
Hello :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a <span>≠ 0) is :
</span><span>Δ = b² -4ac
1 ) </span>Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ <span>< 0 : no reals solutions
in this exercice : -3x²-2x+6 =0.....a = -3 b = -2 c =6
calculate : </span>Δ............................
Answer:
sin²(α)
Step-by-step explanation:
sin⁴(α) − cos⁴(α) + cos²(α)
sin⁴(α) − cos²(α) (cos²(α) − 1)
sin⁴(α) − cos²(α) (-sin²(α))
sin⁴(α) + sin²(α) cos²(α)
sin²(α) (sin²(α) + cos²(α))
sin²(α) (1)
sin²(α)
Answer: Experimental probability.
Step-by-step explanation:
This starts as "based on past experience."
So we can suppose that this estimation is obtained by looking at the mean of the number of guests on the past N weekday evenings. (With N a large number, as larger is N, more data points we have, and a better estimation can be made)
Then, this would be an experimental probability, because it is obtained by repeating an experiment (counting the number of guests on weekday evenings) and using that information to make an estimation.
