False. In a coin, there are 2 possible out comes i.e. a head and a tail. if p is the probability of one side coming up, then the probability of the other side comin up will be q = 1 - p.
Therefore, if the probability of head coming up is 3/10, the probability of tail coming up will be 1 - 3/10 = 7/10.

Density is mass per unit volume.
For the given material that has a mass of 44 grams occupying a volume of 6 cm^3, we divide the mass by the volume, i.e.
density of material = 44 grams / 6 cm^3 = 44/6 grams/cm^3 = 7.3 g/cm^3 (to two significant figures)
Answer:
1306.24 cm².
Step-by-step explanation:
From the diagram given above, we obtained the following information:
Radius (r) = 13 cm
Pi (π) = 3.14
Slant height (l) = 19 cm
Surface Area (SA) =.?
The surface area of the cone can be obtained as follow:
SA = πr² + πrl
SA = πr ( r + l)
SA = 3.14 × 13 ( 13 + 19)
SA = 40.82 (32)
SA= 1306.24 cm²
Therefore, the surface area of the cone is 1306.24 cm².
Hello,
First we work out the equations:
x + y =62 will be the first equation.
2x= y +13 is the second equation.
We can first rewrite the second equation as 2x – y =13.
So we have:
x + y = 62
2x –y =13
KEEP IN MIND: With y being positive in one of the equations and negative in the other, we can combine the equations to quickly eliminate y and solve for x.
x + y = 62
+2x –y =13
3x = 75 divide both sides by 3 to get x.
x = 25
Now that we have x we can substitute the value for x, 25.
25 + y = 62 we can subtract 25 from both sides to get y.
y = 62- 25
y = 37
2(25) = 37 + 13
Therefore,
50 = 50
Have a amazing day.
