Answer:Incorrect.

For example, two equations with same y intercept.

y = 2x + 3

y = 5x + 3

This system has only one solution.

Another example,

y = x + 7

This system has infinitely many solutions.

So she is not correct because of the first example.

Which expression can be used to find the volume of the sphere?

Kryger [21]

Answer:

They used 3.14 for pi:

$V=\frac{4}{3} \pi r^3$

$V=\frac{4}{3} (3.14)(5)^3$

Step-by-step explanation:

$V=\frac{4}{3}\pi r^3$ is the volume of a sphere with radius r.

I think that is the diameter given in the picture.

The radius is half the diameter.

So the radius is 5 since the diameter is 10.

Plug in this gives you:

$V=\frac{4}{3} \pi (5)^3$

Answer:

p= $\frac{181}{301}$

Step-by-step explanation:

30100 have dogs, 18100 have cats.

The question simply asks for a union scenario thus the law of AND & OR is applicable.

Therefore:-Those who have both cats and dogs partially have cats.

$P(X=both \ cat \ and \ dog)=\frac{18100}{30100}\\p=\frac{181}{301}$
