Llana [10]

Answer: Associative

Step-by-step explanation:

Associate is "partner". With this property the parentheses (aka partners) change but the order stays the same.

FYI: If the order changes, that is because a term moved/traveled/commuted to the other side. This is the Commutative property.

The end of a hose was resting on the ground, pointing up an angle. Sal measured the path of the water coming out of the hose and

Travka [436]

Answer:

3.2 feet

Step-by-step explanation:

The equation $f(x)=-0.3x^{2}+2x$ shows the height of water [ $f(x)$ ] and horizontal distance [ $x$ ].

Given the horizontal distance is 4 feet, they want to know the height.

Simply put 4 in $x$ of the equation and solve for $f(x)$ . So,

$f(x)=-0.3(4)^{2}+2(4)\\f(x)=3.2$

So, the height of the water was 3.2 feet above the ground.

If you roll one die two times, what is the probability of getting a 2 on the first roll and a 2 on the second roll? Show work or

koban [17]

Answer: $\dfrac{1}{36}$

Step-by-step explanation:

We know that when two events A and B are independent , then the probability of getting A and B will be :-

$P(A\cap B)=P(A)\times P(B)$

In a fair dice,total outcomes =6

Number of 2's =1

Then, the probability of getting a 2 = $\dfrac{1}{6}$

If you roll one die two times, then the probability of getting a 2 on the first roll and a 2 on the second roll will be:-

$\dfrac{1}{6}\times\dfrac{1}{6}=\dfrac{1}{36}$

Hence, the probability of getting a 2 on the first roll and a 2 on the second roll= $\dfrac{1}{36}$
