Answer:
-5
Step-by-step explanation:
Geometric sequences have common ratios.
You can see if a sequence is geometric by computing:
.
If you get the same result per consecutive pair, then there is a common ratio and the sequence is geometric.
Let's see:
So if this equations holds (if all 3 fractions equal the same thing), then is geometric and we have also have computed the common ratio.
The first fraction results in -250/50=-5.
The second fraction results in 50/-10=-5.
The third fraction results in -10/2=-5.
All three fractions are equal and so the equation holds so it is geometric and the common ratio is -5.
Answer:
43°
Step-by-step explanation:
The first thing you should do is make the equation. We should know that the sum of all the angles is 180. So it should look like this...
Combine like terms:
Subtract the 137 on both sides:
That's it the value of v is 43°.
Answer:
it they were asking probabilty of spinning red one time, like you know we would say 1/4.
but that want twice from us. so im multiplaying by itself.
(1/4)^2 = 1/16
good luck(:
Answer:
703.7cm²
Step-by-step explanation:
Since we must not count the top and bottom 2cm,
- The height of the label is (20-2-2) = 20 - 4 = 16cm
- Finding the curved surface area of a cylinder: 2πrh
where r = radius and h = height.
- Since the diameter is 14cm, the radius is 14/2 = 7cm
- Substituting 'r=7' & 'h=16' into the curved surface area of a cylinder formula:
2π(7)(16)
= (14)(16)π
= 224π
= 703.716754404cm²
≈ 703.7cm²

Answer:
Step-by-step explanation:
Given
See attachment for sample space
Required
From the attached sample space, we have:
---- total outcomes
--- outcomes with 1 Y and 1 P = 2 i.e. (P,Y) and (Y,P)
So, the required probability is:
