66% off
the original price minus 1/3 of the price is 2/3 of the price. 2/3 =66%
A.
1. 9 qt = 2 gallons 1 qt.....(because 1 gallon = 4 qts)
2. 20 oz = 2 cups 4 oz.....(because 1 cup = 8 oz)
3. 2 qts 2 cups = 10 cups...(because 1 qt = 4 cups)
4. 2 miles, 4000 ft = 14560 ft...( because 1 mile = 5280 ft)
5. 14 qts = 3 gallons 2 qts...( because 1 gallon = 4 qts)
6. 1 m ,37 cm = 137 cm ..(because 1 m = 100 cm)
7. 2 c = 16 oz....(because 1 cup = 8 oz)
8. 3 qts, 5 oz = 101 oz...( because 1 qt = 32 oz)
9. 3 qts = 12 cups...( because 1 qt = 4 cups)
10. 256 mm = 25 cm 6 mm ...(because 1 mm = 10 cm)
11. 1 qt, 12 oz = 44 oz...( because 1 qt = 32 oz)
12. 85 oz = 0 g , 2 qts, 21 oz...( 1 qt = 32 oz)
B.
1. 1 C, 7 oz = 15 oz...( because 1 cup = 8 oz)
2. 5440 yds = 3 miles 160 yds....( because 1 mile = 1760 yds)
3. 8 pts = 4 qts 0 pints...( because 1 qt = 2 pts)
4. 17400 ft = 3 miles 1560 ft
5. 4 m, 1280 yds = 8320 yds...(because 1 mile = 1760 yds)
6. 2 qts 12 oz = 76 oz...( because 1 qt = 32 oz)
7. 2 qts 8 oz = 72 oz...(because 1 qt = 32 oz)
8. 9m 14 cm = 914 cm...( because 1m = 100 cm)
9. 3 miles, 960 yds = 6240 yds...( because 1 mile = 1760 yds)
10. 3 c = 1 pt 1 c......(because 1 pt = 2 cups)
11. 8 ft = 2 yds 2 ft....( because 1 yd = 3 ft)
12. 3 c = 24 oz ...( because 1 cup = 8 oz)
sorry but that is all I have time to do....I did the A's and the B's
The answer to the question is B. 13x + 36
Answer:
for the first picture: 2.16
Step-by-step explanation:
12% of 18 is 2.16:
-convert 12 % to a decimal so 0.12 times 18
also, 12 % percent is 0.12 as a decimal because you move the decimal 2 places to the left to get .12
- multiply 0.12 times 18 to get 2.16 as the answer
I hope this helped for the first pic!
Form the confidence level (99%), we calculate the "alpha" value
alpha=1-(99/100)=0.01
Now, calculate the critical probability (p-start)
p*=1-(alpha/2)=1-(0.01/2)=0.995
z-score could be calculated from p*,,,
z-score=2.57583
Now, calculate the Margin of Error:
standard deviation = s
number of adults = n
ME=(z*s)/(sqrt n)=(2.57583*12)/(sqrt 250) = 1.955
The confidence interval = mean +or- ME
= 70+1.955 or 70-1.955
So that we can conclude that the 99% confidence interval for the mean beats per minute is 68.045 and 71.955
I hope you got the idea!
