<span>In mathematics, a rate is the ratio between two related quantities. Often it is a rate of change. If the unit or quantity in respect of which something is changing is not specified, usually the rate is per unit of time. However, a rate of change can be specified per unit of time, or per unit of length or mass or another quantity.</span>

A spinner is half red and half blue. If you spin the spinner twice, what is the probability that you will get red both times?
Usimov [2.4K]

Answer:  Probability of getting red both times is \frac{1}{4}

Step-by-step explanation:

Since we have given that

A spinner is half red and half blue.

Probability of getting red is given by

\frac{1}{2}

Probability of getting blue is given by

\frac{1}{2}

Since he spins the spinner twice.

Probability that you will get red both times is given by

\frac{1}{2}\times \frac{1}{2}\\\\=\frac{1}{4}

Hence, Probability of getting red both times is \frac{1}{4}

What is the equation of the circle with center (-3,1) that passes through the point (-5, 3)?
Natali5045456 [20]

Answer:

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Step-by-step explanation:

The equation of a circle with center (h,k) and radius r is given by:

(x-h)^2 + (y-k)^2 = r^2

Given

Center = (h,k) = (-3,1)

=> h = -3

=> k = 1

The distance between the center of circle and the point through which the circle passes will be the radius.

The distance formula is given by:

r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2

Given

(x_1,y_1) = (-3,1)\\(x_2,y_2) = (-5,3)

Putting the values in the formula

r = \sqrt{(-5+3)^2+(3-1)^2}\\r = \sqrt{(-2)^2+(2)^2}\\r = \sqrt{4+4}\\r = \sqrt{8}

Putting the values of h,k and r in general form of equation

\{x-(-3)}^2\} +(y-1)^2 = (\sqrt{8})^2\\(x+3)^2+(y-1)^2 = 8

Hence,

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.
