(x-2)(-5x^2+x)=(x)(-5x^2)+(x)(x)+(-2)(-5x^2)+(-2)(x)

Mathematics
1 answer:
bonufazy [111]3 years ago
5 0

Answer:

Step-by-step explanation:

First we will solve the Left Hand Side:

(x-2)(-5x²+x)

Multiply the terms:

= -5x³+x²+10x²-2x

Solve the like terms

= -5x³+11x²-2x

Now we will solve the Right Hand Side:

(x)(-5x²)+(x)(x)+(-2)(-5x²)+(-2)(x)

Multiply the terms:

-5x³+x²+10x²-2x

Solve the like terms:

-5x³+11x²-2x

Hence it is proved that L.H.S = R.H.S....

(c) Use a calculator to verify that Σ(x) = 64, Σ(x2) = 1118, Σ(y) = 628, Σ(y2) = 87,982, and Σ(x y) = 9,627.
amid [387]

The correlation based on the computation is 0.97.

<h3>How to compute the value?</h3>

It should be noted that the question is that we should simply calculate the correlation which is r.

The correlation will be:

= Σ(x y) / (Σ(x²) × Σ(y²)

= 9627/✓(1118 × 87982)

= 9627 ✓98363876

= 9627/9917.86

= 0.97
