There are 6 squares so u multiply 6x3=18 is the total surface area
The sum of all the measurements is just the average times the number.
So if the average of all 92 is 7 the sum of those is
The average of the last two is 7.2 so their sum is
That means the sum of the first 90 is
so the average of the first 90 is
cm
Answer:
Jack
Step-by-step explanation:
90/18 = 5
180/45 = 4
The required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.
Given that,
Monique has 3/4 of tissues. she cuts half of those tissues
<h3>What is the fraction?</h3>
Fraction is defined as the number of compositions that constitute the Whole.
Here,
Let the number of tissue be x,
She has 3 / 4 of the tissues = 3 / 4 x
she cuts half of those tissues = 1 / 2 * 3 / 4 * x
= 3/8x or 37.5% of x
Thus, the required fraction of the tissue she cut is 3 /8, and the percentage is 37.5%.

Answer:
Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ1 = μ2
H1 : μ1 > μ2
Given :
x1 = 21.1 ; n1 = 53 ; s1 = 1.1
x2 = 20.7 ; n2 = 46 ; s2 = 1.2
The test statistic :
(x1 - x2) / √[(s1²/n1 + s2²/n2)]
(21.1 - 20.7) / √[(1.1²/53 + 1.2²/46)]
0.4 / 0.2326682
Test statistic = 1.719
The degree of freedom using the conservative method :
Comparing :
Degree of freedom = n - 1
Degree of freedom 1 = 53 - 1 = 52
Degree of freedom 2 = 46 - 1 = 45
Smaller degree of freedom is chosen ;
The Pvalue from Test statistic, using df = 45
Pvalue = 0.0462
Pvalue < α ; Hence, there is significant evidence to conclude that average age of Gorka student is higher than Yaphoa.
