A researcher has collected the following sample data. The mean of the sample is 5. 3 5 12 3 2 Refer to Exhibit 3-2. The coefficient of variation is _____.
Answers
Answer:
81.24%
Step-by-step explanation:
First we solve for the variance
Sample space of
3,5,12,3,2
n = 5
Variance = s²
= (3-5)²+(5-5)²+(12-5)²+(3-5)²+(2-5)²/5-1
= 4+0+49+4+9/4
S² = 66/4
= 16.5
Secondly we find the standard deviation
= √16.5
= 4.062
Coefficient of variation
Cv = sd/mean x 100
= 4.062/5 x 100
= 406.2/5
= 81.24%

(a)
If 2 chords of a circle intersect then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord.
(b)
If 2 secants are drawn from an external point to a circle then the product of the measures of one secant's external part and the entire secant is equal to the product of the measures of the other secant's external part and that entire secant.
(c)
If a tangent and a secant are drawn from an external point to a circle , then the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant.

An inscribed circle of a triangle is a circle drawn inside a circle so the circle barely touches the sides of the triangle.
(b)
The incentre is at the point of intersection of the triangle's 3 angle bisectors.
(c)
A circumscribed circle of a triangle ( circles drawn around the triangle so that the circle passes through each of the triangles's vertices.
(d)
The circumcentre is at the intersection of the perpendicular bisectors of the triangle's sides.

Answers
P=2(L+W)
P=376
W=89
thus substituting the values in the equation we get;
376=2(L+89)
376/2=(L+89)
solving for L;
188=L+89
L=188-89
L=99 yards
therefore the length is 99 yards

The length of a rectangle is three times its width. If the area of the rectangle is 243 m squared, find it’s perimeter
Answers
Answer: 72
Step-by-step explanation:
L= 3W
area of a rectangle A= LxW
replace L with 3 W
A=3W*W= 3w^2
243=3W^2
243/3=W^2
81=w^2, and W=9
L=3*9=27
P= (L+W)=2(27+9)=72

Mr Tan bought a house for $410 000. He paid a deposit of 30% and took on a loan for the remaining amount. How much was his loan? Give your answer
correct to the nearest ten thousands.
Answers
Answer:
The amount of the loan Mr. Tan borrowed was $ 287,000.
Step-by-step explanation:
Since Mr. Tan bought a house for $ 410,000, paying a deposit of 30% of its value and requesting a loan for the rest of its value, to determine the amount of the loan, the following calculation is required:
100 - 30 = 70
410,000 x 0.70 = X
287,000 = X
Therefore, the amount of the loan Mr. Tan borrowed was $ 287,000.
