Correlation between x & y is 0.6125.

In probability theory and statistics, the cumulative distribution function of a real-valued random variable X, or simply the distribution function of X weighted by x, is the probability that X takes a value less than or equal to x.

The cumulative distribution function (CDF) of a random variable X is defined as FX(x)=P(X≤x) for all x∈R. Note that the subscript X indicates that this is the CDF of the random variable X. Also note that the CDF is defined for all x∈R. Let's look at an example.

Given: CP is perpendicular to AB, CP bisects AB, Prove: CA=CB
expeople1 [14]

Answer:

Proved   CA=CB

Step-by-step explanation:

Given,

In ΔABC,  CP is perpendicular to AB.

And CP bisects AB.

So,  AP=PB   and   ∠CPA=∠CPB=90°

The figure of the triangle is in the attachment.

Now, In ΔACP and ΔBCP.

AP = PB(given)

∠CPA = ∠CPB = 90°(perpendicular)

CP = CP(common)

So, By Side-Angle-Side congruence property;

     ΔACP ≅ ΔBCP

According to the property of congruence;

"If two triangles are congruent to each other then their corresponding sides are also equal."

Therefore,  CA = CB (corresponding side of congruent triangle)

CA = CB  Hence Proved
