96 sq m (A)
6(4*4)=96
The area of something is squared.
Answer:
it would be 75
Step-by-step explanation:
4500/60
The answer:
the complement of the question proposed one of the choices given beneath:
a) 58.8
b) 53.0
c) 29.4
d) 26.5
as we observe at the figure, AOB an isosceles triangle, and OCB is a right triangle
consider OCB
OC =9, OB= radius = 28
the problem is how to find the length of CA, for that C is a midpoint of segment AB, so AC=BC
BC can be found by using pythagorean theorem
OB²= OC² + CB², this implies CB² = OB² - OC²
CB² = 28² - 9² = 784 - 81=703, therefore CB= sqrt (703)=26.51
CB=26.51, since CB= AC, so AC=CB= 26.51
finally the <span>the length of AB is AB = 2 x CB = 2x AC= 2x 26.51= 53.0

the answer is b) 53.0
Answer:

Step-by-step explanation:
Given

Required
Determine the test statistic
Let the dataset of stick be A and Liquid be B.
We start by calculating the mean of each dataset;

n, in both datasets in 6
For A



For B



Next, calculate the sample standard deviation
This is calculated using:

For A




For B




Calculate the pooled variance




Lastly, calculate the test statistic using:

We set

So, we have:


The equation becomes




<em>The test statistic is 31.29</em>
