Answer:
16 glasses
Step-by-step explanation:
If 1 glass = 1/4 liter of juice
then 16 glasses = 4 liters of juice
because 4 divided by 1/4 = 16
5/15 and -1/3 because 5 dived by 5 =1 and 15 dived by 5=3 so it’d be positive and negative 1/3

Answer:
The test statistic | t | =4.45
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the first sample size n₁ = 36
Given that the second sample size n₂ = 34
Mean of the first sample x₁⁻ = 68.5
Mean of the second sample x₂⁻ = 70
<u><em>Step(ii):-</em></u>
Test statistic
![t = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} } } )}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7Bx%5E%7B-%7D%20_%7B1%7D-x%5E%7B-%7D%20_%7B2%7D%20%20%7D%7B%5Csqrt%7BS%5E%7B2%7D%20%28%5Cfrac%7B1%7D%7Bn_%7B1%7D%20%7D%2B%5Cfrac%7B1%7D%7Bn_%7B2%7D%20%7D%20%20%7D%20%29%7D)
![t = \frac{68.5-70}{\sqrt{2(\frac{1}{36}+\frac{1}{34} ) } }](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B68.5-70%7D%7B%5Csqrt%7B2%28%5Cfrac%7B1%7D%7B36%7D%2B%5Cfrac%7B1%7D%7B34%7D%20%29%20%7D%20%7D)
![t = \frac{-1.5}{0.337} = -4.45](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B-1.5%7D%7B0.337%7D%20%3D%20-4.45)
The test statistic | t | = |-4.45| =4.45
Answer:
48 students in science
Step-by-step explanation:
Let r = students in robots club
s = students in science club
r+s = 84
s = r+12
Substitute the second equation into the first
r+(r+12) = 84
Combine like terms
2r+12 = 84
Subtract 12 from each side
2r = 84-12
2r = 72
Divide by 2
r = 72/2 = 36
We need to find s
s = r+12
s = 36+12
s = 48
There are 48 students in the science club
