Since y=x has the same coefficient (of 1), this equation has a 1:1 ratio (another word for "it has the proportionality of 1).


If it's wrong, I'm sorry... Khan Academy is a little annoying...

y =\frac{10}{11}x \rightarrow \frac{10}{11}

y=\frac{7}{8}x \rightarrow \frac{7}{8}

y = \frac{3}{15} \rightarrow \frac{1}{5}

y = x \rightarrow 1

<em>From the information given above, </em><u><em>D is the answer</em></u><em> which has a constant proportionality equal to 1. </em>

If one tosses a coin three times, write dow nthe possible observed number of heads and their probabilities
seropon [69]
You need to find the probability of Heads, Heads, Heads in 3 tosses;

P(HHH)= (1/2)(1/2)(1/2) <-- each toss has 2 possibilities and heads is one 
P(HHH)=1/8

Therefore, the probability of flipping 3 heads on a fair coin is 1/8 

Hope I helped :)

Find the difference (7a-6b+7) - (8a-2)
olga nikolaevna [1]
Hey there!

Let's set up our expression:

(7a-6b+7)-(8a-2)

In order to simplify, we can use that subtraction sign and distribute it, using the distributive property. We have:

7a-6b+7-8a+2

Notice how it's plus two, because a negative times a negative two is a positive two. Now, it's a matter of finding the like terms and adding or subtracting them. These like terms can either have no variable, or have different coefficients but the same variable. That means our like terms are the 7a and -8a, and the 7 and 2. There's no like term for the 6b. That means we have:

(7a-8a) - 6b + (7+2) =

-a - 6b + 9

Hope this helps!
