The best approach to this is to use the formular
Standard error = standard deviation / sqrt( sample size)
standard deviation = 0.75 hours
sample size = 35
Hence, Standard error = 0.75 /sqrt(35) = 0.126 = 0.13
Answer:
4 is the number.
Step-by-step explanation:
Take the missing number as x,
→ (x × 3) - 4 = (x × 2)
→ 3x - 4 = 2x
→ 3x = 2x + 4
→ 3x - 2x = 4
→ [ x = 4 ]
Hence, the number is 4.
Answer:
There are 14 pints in 7 quarts.
-3/4 + p = 1/2
p = 1/2 + 3/4
p = 2/4 + 3/4
p = 5/4 or 1 1/4
