Answer:
For 3 quarters, the probability that all 3 quarters will land heads up is ;
P = 1/2 × 1/2 × 1/2 = 1/8
P = 1/8
Step-by-step explanation:
The probability that one quarter will land heads up is 1/2.
For 3 quarters, the probability that all 3 quarters will land heads up is ;
P = 1/2 × 1/2 × 1/2 = 1/8
P = 1/8
The elevation of the city is between -15 and -16
Step-by-step explanation:
The Earth surface is highly uneven. Hence for relative comparison, scientist over the world assume the sea level as the reference point (meaning that sea level is considered to be at 0 elevation and all other elevations and depths are calculated regarding the sea level)
As given in the question city’s elevation is 15.3 feet below sea level. Hence the city is below the sea level by 15.3 feet
On the mathematical scale below 0 would mean the number system is negative. Similarly, the city is located at -15.3 feet when compared to sea level which is at 0 feet.
Hence -15.3 would lie between -15 and -16
Answer:
0
Step-by-step explanation:
1/3(21)-1-1/2(12)
7-1-6=6-6=0
The distributive property combines multiplication with addition and multiplication with subtraction together in order to simplify the equation. It is named as such because the number outside of the open and close parenthesis are distributed to the terms inside. Say for example, the equation given is 5(2x - 3). According to the distributive property, you distribute 5 by multiplying to each of the terms inside the parentheses. The solution would be: 5*2x + 5*-3 = 10x - 15. As you can see, it involved multiplication with addition and subtraction. Generally, you just have to add all the terms while making sure you carry the sign of the integer along when you multiply them just as shown in my example.
The distance fro, (12,-5) to (-3,7) is 
First, you must set up the distance equation.

Then, you must add like terms.

Next, simplify exponents.

Finally, simplify the radical.

The radical cannot be simplified, so the answer is
