A₆ =12
a₇ = ?? = x
a₈ 27
In this case x is the geometric mean & as per the formula
geometric mean of 2 numbers =√(a₆ * a₈) = √(12*27)
& x=18.
Proof:
Find the common ratio between a₇ & a₆ ==> = ( x) / 12
now find the common ration between a₈ & a₇ ===> =27 / (x)
x/12 = 27/x ===> x² = 12*27 ==> x² = 324 & x =√324 = 18
Well first we need to find how we can turn 25 into 100
Well one way would be to multiply by 4
25 x 4 = 100
Since we multiplied the bottom number by 4 we should multiply the top number by 4.
So..
19 x 4 = 76
So our new fraction is..
76
-----
100
Now we can easily turn this into a decimal.
76/100 = 0.76
Answer = 0.76
Good Luck! :)
you said you will give use 20 points but it is marked as 5 Points.
The area of a triangle is base length x height then divide all by 2,
so 12 x 10 /2
=60 ft²
Histograms are useful when we have data which can be divided into several classes or groups. The histogram shows the trend of each class and the trend among the different classes. For example when we have about 50 different values ranging from 1 to 20, it will be a better approach to draw a histogram in this case by dividing the data into small ranges e.g 1 to 4, 5 to 9 and so on and counting the frequency for each class.
Dot plot is useful when we have a small number of individual values. In this case we can visualize how many times each individual value occurred in the data. This is useful when the number of values in the data is less.
In the given scenario, we have 12 values in total ranging from 1 to 5. So making a dot plot would be the best choice. A histogram would not be useful in this case.
Therefore, the correct answer is option D. Dot plot, because a small number of scores are reported individually
