Let's imagine that we have in the deck 52 cards. So what we need to do is to make a kind of "progression".So let me explain this by doing the procedure. we can use is like this:
4/52 * 3/51 * 2/50 * 1/49 =
<span>24 / 6497400 = </span>
<span>1 / 270725 </span>
<span>3.694e-6</span>
4 : 28 is the same as 4/28
4/28 = 1/7
The answer is C
Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
Answer:
in geometry, a circle is the curve that forms the boundary of a disc. Curves, like lines, have zero width and thus zero area.
For some reason, this very simple thing doesn’t seem to be taught much - I certainly recall my maths teachers referring to the area of a circle instead of the area of a disc!
As you haven’t mentioned the radius of the circle, let us consider a generic circle of radius r, thus we want to find the height of a triangle whose area is πr².
Step-by-step explanation:
Answer:
Equation: S = 650 + 40w
Ryan has $1290 in his savings after 16 weeks.
Savings = S
weeks = 16
S = 650 + 40w
S = 650 + 40(16)
S = 650 + 640
S = 1290
