Answer: B.) 32.154 in²

Step-by-step explanation: divide 6.4 by 2 to get the radius then it is 3.2

then the formula to find the area of a circle is Area = πr²

π = 3.14

so... Area= 3.14x3.2²

                = 3.14x10.24

                = 32.1536

then when u estimate the value u get 32.154 in²

1.) What is the mode of the data ? Show work ( A.3, B.5, C.8, D.10 )
ArbitrLikvidat [17]
Hey there.

1.) The mode is the number that's most frequent in a given list.
In our list, we have 2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10.
Our most frequent number is 6; therefore, our mode is 6.

2.) The median is the number in the middle of a list organized from least to greatest.
2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10;
4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9;
4, 5, 5, 5, 6, 6, 6, 6, 7;
5, 5, 5, 6, 6, 6, 6;
5, 5, 6, 6, 6;
5, 6, 6;
6.
6 is our median.

I hope this helps, despite your answer choices not providing the correct answer.

Which of the following is the x-coordinate of the solution to the system shown below
lyudmila [28]
Answer is x = 7

if u plug in 7 in the second expression, we can get 7 - y = 4, isolate y and then we get 3.

Now, plug in 7 in the first equation to get 2(7) + y = 17. that results to 14 + y = 17. isolate y again and then thats also 3.


so:
x = 7
y = 3
