Answer:
37 hours and 12 minutes
Step-by-step explanation:
six men completed a task in 24 hours and 48 minutes which means (24 x 60) + 48 = 1488 minutes
x is the number of minutes it would take 4 men to complete
6(1488) = 4x
8928 = 4x
x = 2232
x = 2220 + 12 or 37 hours and 12 minutes
T(p) would be an accurate answer. This situation likens to the f(x) function, where y is the function of x and so dependent on x. The cost of the tomatoes is dependent on the price per pound, so cost would be in the f place and price per pound would be in the (x) place.
Answer:
(-3.07, 11.07)
Step-by-step explanation:
Given that a sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used eighteen adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each.
Group Group One Group Two
Mean 300.00 296.00
SD 8.00 6.00
SEM 2.67 2.00
N 9 9
The mean of Group One minus Group Two equals 4.00
standard error of difference = 3.333
df = 16
t = 1.2000
Margin of error = 3.3333* t critical = 3.3333*2.121
95% confidence interval of this difference: From -3.07 to 11.07
Answer:
a = 15/2
Step-by-step explanation:
3a−15=4a−3a
Combine like terms
3a - 15 = a
Subtract 3a from each side
3a-3a−15=a−3a
-15 = -2a
Divide each side by -2
-15/-2 = -2a/-2
15/2 =a
