We can Notice from the Figure that X is the Centroid of the Given Triangle.
We know that Centroid divides each Median in the Ratio 2 : 1
From the Figure : CH is one of the Median
Given the Length of CH is 33 ft
X divides the Median CH in the ratio 2 : 1
Let us Divide the Median CH into 3 Equal Parts
Length of Each Part of 3 Equal Parts =
⇒ Length of CX = 2 × 11 = 22 ft
The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
Answer:
ED = 8 units
Step-by-step explanation:
ΔAEB and ΔDEC are similar triangles, hence the ratios of corresponding sides are equal, that is
= , that is
= ( cross- multiply )
6(2x + 4) = 9(x + 4) ← distribute parenthesis on both sides
12x + 24 = 9x + 36 ( subtract 9x from both sides )
3x + 24 = 36 ( subtract 24 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Hence ED = x + 4 = 4 + 4 = 8 units
Answer:
x = 6
Step-by-step explanation:
10x = 5 x 12 = 60
x = 6
