Answer:
x = -4/9
Step-by-step explanation:
X + B = C
x + (-8/4) = (22/-9)
x = (8/4) - (22/9)
x = 2 - 22/9 = 18/9 - 22/9 = -4/9
Answer:
We are 95% confident that the average weight of the heaviest egg that is still medium size is 3.52 oz
Step-by-step explanation:
Mean = 3.2 oz, sd = 0.13 oz
Assuming there are 3 heavy eggs, n= 3, degree of freedom = n-1 = 3-1 = 2, t-value corresponding to 2 degrees of freedom and 95% confidence level is 4.303
Error margin = t×sd/√n = 4.303×0.13/√3 = 0.32 oz
Upper limit (heaviest egg that is still medium size) = mean + error margin = 3.2 + 0.32 = 3.52 oz
Answer:
48
Step-by-step explanation:
so we just have to set up this expression
it would be
8(4+2)
this would be
8(6)
this equals 48
Vol. of a rectangular box is L*W*H.
Here, that comes to V = (4.5 in)(9 in)(6.5 in) = 263.25 cubic inches.
Just look up 53 1/3 yards in feet. This would mean that the football field is 160 feet.
