The answer is probably 2 because if you plug in the numbers you would get
3x-4=-12 divided by -6 = +2.
Answer:
11.9
Step-by-step explanation:
-11.9/-1
so the both cancel out each other
so it will just be 11.9 ,since it is -1
Answer:
−35.713332 ; 0.313332
Step-by-step explanation:
Given that:
Sample size, n1 = 11
Sample mean, x1 = 79
Standard deviation, s1 = 18.25
Sample size, n2 = 18
Sample mean, x2 = 96.70
Standard deviation, s2 = 20.25
df = n1 + n2 - 2 ; 11 + 18 - 2 = 27
Tcritical = T0.01, 27 = 2.473
S = sqrt[(s1²/n1) + (s2²/n2)]
S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]
S = 7.284
(μ1 - μ2) = (x1 - x2) ± Tcritical * S
(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284
(μ1 - μ2) = - 17.7 ± 18.013332
-17.7 - 18.013332 ; - 17.7 + 18.013332
−35.713332 ; 0.313332
Answer:
951.15 ltr
Step-by-step explanation:
first you convert inch into cm just to make things easier
1 inch = 2.54cm
so,
radius(r)= 24 inch = 24×2.54= 60.96cm≈ 61 cm
then calculate the volume of the sphere
i.e.
V = 4/3(πr³)= 4/3×22/7× 61³= 951158.47 cm³
Now that we have volume
we know that,
1 ltr = 1000cm³
sooo,
- x ltr= 951158.47÷1000= 951. 15 ltr
How do people......I just don't understand this
