Given:

Radius of circle = 4 feet

To find out:

Find the area of a circle?

Solution:

Area of circle = πr²

= 22/7 × 4²

= 22/7 × 16

= 352/7

= 50.28 ( approx )

Hence, the area of circle is 50.28 feet²

Hey!!

Solution,

Radius(r)=4 ft

Area of circle=?

Now,

Area of circle= pi (r)^2

 =3.14*(4)^2

 = 3.14*16

 =50.24 ft^2

The area of a circle is 50.24 ft^2

Hope it helps

The valid probability distributions are the ones in options C and D.

<h3>Which of the following are valid probability distributions?</h3>

For discrete random variables with probabilities p₁, p₂, ..., pₙ, there are two rules:

All of these probabilities are numbers between 0 and 1.
p₁ + p₂ + ... + pₙ = 1.

So, for the first rule we can discard the first option, where we have negative probabilities.

To check the other 4 options, just add the probabilities and see if the addition gives 1.

The options that add up to 1 are C and D, so these two are the correct options.

D: 1/5 + 1/10 + 1/10 + 1/10 + 1/5 + 1/10 + 1/10 + 1/10 = 1

C: 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 1

Jack said that if you take a number and multiply it by a fraction, the product will always be smaller than what you started with

ELEN [110]

Answer:

Is not correct. The product not always will be smaller.

Step-by-step explanation:

A fraction could increase a number if you multiply it.

If the numerator is higher to the denominator, it will increase it.

If the numerator is smaller to the denominator, it will decrease it.

For example,

10 x 4/3

For fraction multiplication, multiply the numerators and then multiply the denominators to get

10×4/1×3=40/3= 13,33

13,33 is higher than 10.

5 x 10/3

For fraction multiplication, multiply the numerators and then multiply the denominators to get

5×10/1×3=50/3

16,66 is higher than 5.
