Answer:
Kindly check explanation
Step-by-step explanation:
Total number of coin flips = 50
Number of times both coins landed head up = 20.
Hence probability of having two heads :
Probability = required outcome / Total possible outcomes
P(both heads up) = 20/50
Comparing 20/50 to 50%
We convert 20/50 to percentage :
(20/50) × 100%
0.4 × 100% = 40%
20/50 is equivalent to 40%
Hence, 40% is less than 50%
What you have to do here is do 6x5 to give you 30 and add it to the numerator to give you 32. Then put it over 5 to give 32/5
Answer:
D
Step-by-step explanation:
7.6/3.8 = 2
The dilation is by scale factor 2.
8/2 = 4
11/2=5.5
Calculate the volume.
Cross section × height
4 × 3.8 × 1/2 × 5.5 = 41.8
The volume of the smaller prism is 41.8 ft³.
Answer:
These have no solution:
- 2x < x+1 and x+1 > 3
- 3x -5 > 1 and x < 2
Step-by-step explanation:
1. 2x < x+1
x < 1 . . . . . subtract x
__
x + 1 > 3
x > 2 . . . . subtract x
No solution: x cannot be both > 2 and < 1.
_____
2. 3(x +2) > x
3x + 6 > x . . . . eliminate parentheses
2x + 6 > 0 . . . subtract x
x + 3 > 0 . . . . . divide by 2
x > 0
Solution: 0 < x < 2
_____
3. 5x ≥ 10
x ≥ 2 . . . . . divide by 5
__
2x ≤ 4
x ≤ 2 . . . . . divide by 2
Solution: 2 ≤ x ≤ 2 . . . . x = 2
_____
4. 3x -5 > 1
3x > 6 . . . . . . . add 5
x > 2 . . . . . . . . divide by 3
No solution: x cannot be both < 2 and > 2.
the answer is 45 is the legnth
