Answer:
Step-by-step explanation:
Plug x for y and y for x.
y = 2x^2 + 2
x = 2y^2 + 2
Then isolate the y variable.
x - 2 = 2y^2
sqrt(x - 2) = 2y
(sqrt(x - 2))/2 = y
Hi there! The answer is j = - 42.
In order to find the value of j, we need to set up and solve an equation.
The sum of j and 47 can be rewritten as
j + 47
The sum described above equals 5, so now we have all the information we know to set up the equation.
j + 47 = 5
Subtract 47 from both sides.
j + 47 - 47 = 5 - 47
j = - 42.
The answer is j = - 42.

Answer:
θ = 36.9°
Step-by-step explanation:
Trigonometric ratios in a right triangle will be,
Sinθ = =
Cosθ = =
Tanθ = =
In the picture attached,
Given sides are,
AB = 5 and BC = 4
Therefore, to find the given angle θ only Cosine will be applicable.
Cos θ =
=
θ =
θ = 36.87°
θ ≈ 36.9°
Answer:
X probability = 0.02
Cumulative frequency at x ( 6 ) = 1
Step-by-step explanation:
X P ( X ) Cf ( X )
1 0.58 0.58
2 0.18 0.58 + 0.18 = 0.76
3 0.10 0.76 + 0.10 = 0.86
4 0.07 0.86 + 0.07 = 0.93
5 0.05 0.93 + 0.05 = 0.98
6 0.02 0.98 + 0.02 = 1
B) ABCD is a rhombus as all the sides are congruent (equal)
