Answer:

Find the median of this data

21+23+60+60+50+54+54+59+26+15+43+15=480/ 12 = 40

Now the median should be 50 so take 50 - 40 = 10

The missing number from the data is 10

Answer: Correct me if i'm wrong, but I think the closest answer would be 45.

Step-by-step explanation:

Arrange data values from lowest to highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

Correct answer is D.

$\frac{10x^6y^3 + 20x^3y^2}{5x^3y}
\\
\\ \text{common in the numerator is }
\\
\\ 10x^3y^2
\\
\\ \text{so}
\\
\\ \frac{10x^3y^2(x^3y + 2)}{5x^3y}
\\
\\ \text{cancel common factors... }
\\
\\ 2y(x^3y + 2) = 2x^3y^2 + 4y$

What is the slope of a line perpendicular to the line whose equation is -2x+20y=6

QveST [7]

Answer:

-10

Step-by-step explanation:

Solving for y gives ...

20y = 2x +6

y = 2/20x +6/20 = 1/10x +3/10

The slope of the given line is the coefficient of x: 1/10. The slope of the perpendicular line is the opposite reciprocal of this: -1/(1/10) = -10.

The perpendicular line has a slope of -10.

Nina needs to purchase 1/3 of a pound of chicken for each person in her family. There are eight people in her family. How many p

4vir4ik [10]

Answer:

$2\frac{2}{3}$ pounds

Step-by-step explanation:

Each person will eat 1/3 pound of chicken, and there are 8 people. So, we want eight 1/3 pounds. We can write this as an addition problem:

1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3

This addition problem is equivalent to the multiplication problem: 8 * (1/3)

Both will yield the same result: 8/3 pounds = $2\frac{2}{3}$ pounds, and that's the answer.

Hope that helps!

Find two consecutive whole numbers such that the sum of their squares is 221.

Law Incorporation [45]

$n^2+(n+1)^2=2n^2+2n+1=221$
$2n^2+2n=220$
$n^2+n=110$
$n^2+n-110=0$
$(n-10)(n+11)=0\implies n=10,n=-11$

But since $n$ must be a whole number, we ignore $n=-11$ . So the two integers are $n=10$ and $n+1=11$ .
