Answer:
- 16. 3/8
- 17. 1/8
- 18. 5/18
- 19. 0
- 20. 1
Step-by-step explanation:
<u>As per the spinner we have:</u>
- Green = 1/2 - 1/16 = 7/16
- Red = 1/4
- Purple = 1/8
- Orange, blue, yellow = 1/16
<u>16. P(red, yellow, blue) = ?</u>
- P = 1/4 + 1/16 + 1/16 = 3/8
<u>17. P(orange, yellow) = ?</u>
<u>18. P(green, blue, purple) = ?</u>
- P = 7/16 + 1/16 + 1/8 = 10/16 = 5/8
<u>19. P(pink) = ?</u>
<u>20. P(red, orange, yellow, green, blue, purple) = ?</u>
- P = 1 as all possible colors selected
Answer: -3 < or = -j < -7
Step-by-step explanation:
-1 < or = 2-j < -5

Answer:
8
Step-by-step explanation:
The ratio of nurses to docters a month ago was 3:5. Now, it's 4:5. You can tell that there aren't 4 nurses because 3 => 4 is only one nurse. If you duplicate both ratios (multiply both sides by 2), you get 6:10 (for a month ago) and 8:10 (now). This is correct because 6+2=8. Hope it helps!
Answer: Option A
About 0.02 pounds
Step-by-step explanation:
We know that density is defined as:
Where
d is the density
m is the mass
v is the volume
We want to calculate the helium-air mass of a spherical balloon and we know its density and the diameter of the balloon.
Then we can calculate its mass.
1) We use the diameter of the spherical globe to calculate its volume.
The volume of a sphere is:
and
So
2) Use the density formula to find the mass
<em>The answer is 0.02 pounds</em>
