Answer:
a
b
Step-by-step explanation:
From the question we are told that
The sample size is n = 60
The first sample mean is 
The second sample mean is 
The first variance is 
The first variance is 
Given that the confidence level is 95% then the level of significance is 5% = 0.05
Generally from the normal distribution table the critical value of 
is
Generally the first standard deviation is
=> 
=> 
Generally the second standard deviation is
=> 
=> 
Generally the first standard error is
Generally the second standard error is
Generally the standard error of the difference between their mean scores is mathematically represented as
=> 
=>
Generally 95% confidence interval is mathematically represented as
=> 
=>
This is a simple problem
First, take common sense and apply it here. The problem doesn't specifically tell you what the shape ACTUALLY is, but we can also apply what we know about geometry here, as well as what we know in general. Fish tanks most commonly come in 2 shapes: Square's and Rectangles. Fish tanks are what we call "3D" objects (meaning it's just not flat like a piece of paper", and the shapes are known as "Cubes and Rectangular Prisms".
Well, we know that squares/cubes have to have even sides. The problem states the tank is 5(l) by 2(w) by 2(h). This means it CAN'T be a cube, thus meaning it's a rectangular prism.
Now, to calculate volume, we have to know the formula. For this, the formula for volume is as follows: V=lwh
This means Volume=Length*Width*Height
So, do replace the words with what you know you already have. Let's make a list:
Length=5
Width=2
Height=2
V=lwh-----V=5*2*2
Now, work it out. 5*2=10*2=20, Left to right
Your answer here is V=20
~Hope this helps!
B is the correct answer I think
Answer:
On the first one, multiply 6 by 3 (18) and subtract from 27 = $11
Step-by-step explanation:
$11 divided by three
About $3.66 Per day. I don't know how to do those graphs you doin but that's the answer to the question itself. Hope I helped?
The second one:
Divide 77 by 7 days (11)
Then subtract 4 from that (which gives you 7) because you need to know how much water is used on the flowers, not the shrubs. So, the answer should be 7. Correct me if I'm wrong, people.
