Answer:
Step-by-step explanation:
A company claims that its soup vending machines deliver exactly 8 ounces of soup to every customer.
This means that the null hypothesis is that the mean is exactly 8, that is:
You do not want the vending machines to deliver too much or too little soup.
We don't want the mean to be different from 8, which means that the alternative hypothesis is given by:
This is a lesson in order of operations...
PEMDAS- parentheses, exponents, multiplication, division, addition, and subtraction... That is the order in which you have to proceed during any math problem..
Your question gives an excellent example of why.
8x3+4=
in this question, we would do multiplication then addition for the answer...
24 + 4 = 28
Now the other one
8 x (3+4) =
in this expression, we would do what is inside the parentheses first, the addition. Then we would multiply...
8x 7 = 56
You see we have the same numbers and we are performing the same operations, but the difference is in the order that we perform them. As you can see it does make a difference because we get a different result.
28 vs 56
Answer:
x=vel of d
y=vel oh h
t1=time taken by d
t2=time taken by h
we have 4t1=5t2..............(1)
also
3xt1=4yt2....................(2)
comparing 1 and 2
x/y=16/15

Answer:
384 Square Inches
Step-by-step explanation:
Given a square pyramid with base side edge and slant height
In the given pyramid:
- Slant Height=20 inches
- Base Edge = 8 Inches
Therefore:
Area of Base, A =8 X 8 =64 Square Inches
Perimeter of base, p =4 X 8 =32 Inches
