Answer:
The relative frequency of landing on tails is 0.3.
Step-by-step explanation:
The relative frequency of an outcome A is:
The number of trials in which the outcome A happened divided by the total number of trials.
In this problem, we have that:
20 coin tosses, so 20 trials. On 6, it landed on tails.
6/20 = 0.3
This means that the relative frequency of landing on tails is 0.3.
Yes, i believe so because u can count back twice and u will get 5. You could al so do: 7-2=5. Hope this helps
Answer:
All the properties of a rhombus apply (the ones that matter here are parallel sides, diagonals are perpendicular bisectors of each other, and diagonals bisect the angles). All the properties of a rectangle apply (the only one that matters here is diagonals are congruent). All sides are congruent by definition.
Step-by-step explanation:
5x + 2x
that is the same as (5 + 2)x
and that is the same as (7)x = 7x
so, for the second part of the problem we are actually comparing
7x
and
7x - 1
there is therefore no way for the two expressions to deliver the same value for the same x.
the values of 7x are always larger by one than the values of 7x - 1
so, e.g.
x = 1
5×1 + 2×1 = 5 + 2 = 7
7×1 - 1 = 7 - 1 = 6
x = 2
5×2 + 2×2 = 10 + 4 = 14
7×2 - 1 = 14 - 1 = 13
x = 3
5×3 + 2×3 = 15 + 6 = 21
7×3 - 1 = 21 - 1 = 20
x = 4
5×4 + 2×4 = 20 + 8 = 28
7×4 - 1 = 28 - 1 = 27
x = 5
5×5 + 2×5 = 25 + 10 = 35
7×5 - 1 = 35 - 1 = 34
