Experimental probability is number of observed specific outcomes divided by the total number of observations...in this case the experimental probability of making a save is:
27/29≈0.931
We won't have a function if for same value of x in (x,y) we get different values y.
So first step: figure out k so that the first coordinate (x) is the same:
3k-4=4k | solve for k
k = -4
no check the values y for the elements of the relation
x = 3k-4 = -12-4=-16
so at -16 we get (-16,16) and (-16, 32), which mean for k=-4 the relation is not a function.
Let me know if you have any questions.
Answer:
<h2>S.A. = 62</h2>
Step-by-step explanation:
We have:
two rectangles 2 × 3
two rectangles 3 × 5
two rectangles 2 × 5
Calculate the areas:
A₁ = (2)(3) = 6
A₂ = (3)(5) = 15
A₃ = (2)(5) = 10
The Surface Area:
S.A. = 2A₁ + 2A₂ + 2A₃
S.A. = (2)(6) + (2)(15) + (2)(10) = 12 + 30 + 20 = 62
Answer and Explanation:
Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:
x = 4√(2)
y = 2(4) = 8
because where 4 = T,
x = T√2 and y = 2T
so again:
