Answer: OPTION C.
Step-by-step explanation:
Direct variation, by definition, has the form shown below:
y=kx
Where k is the constant of proportionality.
Then if you solve fo y from the given equation, you obtain the following form:
Therefore y varies directly with x².
Answer:
No, he is wrong
Step-by-step explanation:
To find that probability, the first thing we need to know is the total number of coins present.
Mathematically, that would be 3 + 2 + 3 = 8
Since there are 8 coins, the probability of selecting a dime is number of dimes/total number of coins = 2/8 = 1/4
The probability we want to work with is that the two selections are dimes, let’s say with replacement.
That means; first selection is a dime and second selection is also a dime
Mathematically in probability, the term and means that we have to multiply our results.
So the probability that both are dimes would be 1/4 * 1/4 = 1/16
And this makes his answer wrong
Answer:
Step-by-step explanation:
Cosine is the adjacent side of the triangle divided by the hypotenuse.
The numerator is going to be the side adjacent to the angle 53
So the top number is y.
The hypotenuse is the side opposite of the right angle. So the bottom number is 34
