Answer:

Option C is correct.

Step-by-step explanation:

Diego solved an equation by multiplying both sides of the equation by 6.

Then he checked that 6 is the correct solution by substituting it back into the equation.

The properties that Diego used are :

C: multiplication property of equality and substitution property of equality

The multiplication property of equality states that if we multiply both sides of an equation by the same number, the sides remain equal.

And the substitution property of equality states that if x = y, then x can be substituted in for y in any equation. Similarly, y can be substituted for x in any equation.

Therefore, Diego used both these properties. (Option c)

if tom spins the spinner 80 times work out an estimate for the number of times the spinner will land on 3 please help me
NNADVOKAT [17]

Answer:

The estimated number of times the spinner will land on 3 is 20.

Step-by-step explanation:

The complete question is:

A four-sided spinner is provided. If Tom spins the spinner 80 times then work out an estimate for the number of times the spinner will land on 3.

Solution:

Assume that the four-sided spinner is unbiased.

That is all the four outcomes are equally likely to be selected.

The probability that the spinner lands on any of the four numbers is:

P(1) = P (2) = P (3) = P (4) = 0.25

It is provided that Tom spins the spinner <em>n</em> = 80 times.

The spinner can land on any of the four numbers independently.

The random variable <em>X</em>, defined as the number of times the spinner lands on 3, follows a Binomial distribution with parameters <em>n</em> = 80 and <em>p</em> = 0.25.

The expected value of <em>X</em> is:

E(X)=np

        =80\times 0.25\\=20

Thus, the estimated number of times the spinner will land on 3 is 20.

Hi, I think what you need to do is multiply 21 x 4 x 1/3. If you need help multiplying there’s a helpful website called Calculator Soup that is very helpful.
