Answer:

A ≈ 78.54

Step-by-step explanation:

Area of a circle is A=πr^2

Since you do not know r (radius) you take the formula for the circumference of a circle (C=2πr), plug in 31.4 for C, and solve for r

Now that you have the radius of 4.99746521, you round it up to 5 and solve the area formula with 5 in as r.

The median is 7. By definition of "median," half of the data values are below 7; half are above 7. Thus, the first statement is FALSE.

Spread: in the 2nd statement we are comparing the spread from lower quartile (4) to the median (7) and that from the median (7) to the upper quartile (9). In other words, we're comparing 3 to 2. This statement is TRUE.

The 3rd statement is the opp. of the 2nd statement, and thus is FALSE.

The 4th statement is FALSE. See my comments regarding the 1st statement.

5x+2y = 19<br> 1x + 4y=13
Mama L [17]

Answer:

{x,y} = {25/9,23/9}

Step-by-step explanation:

// Solve equation [2] for the variable  x  

 

 [2]    x = -4y + 13

// Plug this in for variable  x  in equation [1]

  [1]    5•(-4y+13) + 2y = 19

  [1]     - 18y = -46

// Solve equation [1] for the variable  y  

  [1]    18y = 46  

  [1]    y = 23/9  

// By now we know this much :

   x = -4y+13

   y = 23/9

// Use the  y  value to solve for  x

1) P=2w +2l
46=2w +14
32=2w
16= w or width

2) A=lw
A=7 x 12
A= 84

3) A= 12 x 21
A= 252
