Answer:
surface area of cylinder= 2πrh + 2πr²
2×22/7×1×8+2×22/7×1×1
<u>352</u><u>.</u> + <u>4</u><u>4</u>
7. 7
= 50.3 + 6.25
= 56.55cm²
Answer:
Just like multiplication is adding the same number multiple times, dividing can be described as subtracting the same number multiple times.
Ex:
4 x 3 = 12
4 + 4 + 4 = 12
8/2 = 4
8 -2 -2 = 4
Answer:


Step-by-step explanation:
Let the salted package be represented with 1 and the unsalted, 2.
So:
Mean of salted package
Mean of unsalted package
Considering the given options, the null hypothesis is that which contains =.
So, the null hypothesis is:

The opposite of = is
. So, the alternate hypothesis, is that which contains 
So, the alternate hypothesis is:

1. "All real numbers" is the one domain of the equation y = x2 − 6x + 1 among the following choices given in the question. The correct option among all the options that are given in the question is the fourth option or option "D".
2. "Left by 4 units" is the one among the following choices given in the question that gives the direction and by how many units f(x) be shifted to obtain g(x). The correct option is option "A".
Based on the wording of the question, I believe that the answer allows you to pick more than one. However, there still may only be one answer.
