HZC ~ PEF. If CH = 20, find FP If it can be determined with is FP

Natasha2012 [34]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

According to given expression, we can say that the Triangles HZC and PEF are congruent, Therefore their corresponding sides will be equal.

that is :

CH = FP

and value of CH = 20 units

So, FP = CH = 20 units

hence, value of FP can be determined .

If the sum of squares for a sample containing 51 items equals 200, what is the standard deviation?

Mashcka [7]

The standard deviation is 1.98. Option A is correct.

The standard deviation formula is given as

$\sigma = \sqrt{\frac{SS}{n} }$

where:

SS is the sum of squares = 200
n is the sample size = 51

Substitute the given parameters into the formula to have:

$\sigma = \sqrt{\frac{200}{51} }\\\sigma = \sqrt{3.922}\\\sigma = 1.980$

Hence the standard deviation is 1.98

Determine whether the quadrilateral is a parallelogram using the indicated method Q(-10,-2), R(1,-1), S(1,-7), T(-11,-8) (Distan

myrzilka [38]

Answer:

The quadrilateral is not a parallelogram

Step-by-step explanation:

we know that

In a parallelogram opposite sides are parallel and congruent

Find the length of the sides of the quadrilateral

step 1

Find the distance QR

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

Q(-10,-2), R(1,-1)

substitute

$d=\sqrt{(-1+2)^{2}+(1+10)^{2}}$

$d=\sqrt{(1)^{2}+(11)^{2}}$

$d=\sqrt{122}\ units$

step 2

Find the distance TS

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

T(-11,-8), S(1,-7)

substitute

$d=\sqrt{(-7+8)^{2}+(1+11)^{2}}$

$d=\sqrt{(1)^{2}+(12)^{2}}$

$d=\sqrt{145}\ units$

we have that

QR and TS are opposite sides

In a parallelogram opposite sides are congruent but in this problem

$QR \neq TS$

$\sqrt{122}\ units \neq \sqrt{145}\ units$

therefore

The quadrilateral is not a parallelogram
