Find the area of the shaded region (in the photo and step by step response please)

Mathematics
1 answer:
irina1246 [14]3 years ago
3 0

Step-by-step explanation:

Area of shaded =Area of Outer rectangle - Area of Inner rectangle.

Area of inner rectangle = L× B.

L=18

B=11

Area of inner rectangle = 18×11

=198m^2

To find the full breadth of the outer rectangle

=2 in +11 + 2 in

=15

To find the full length of the outer rectangle

=2 in + 18 + 2 in

=22

Area= 22 × 15

Area = 330m^2

Area of shaded portion = 330 - 198

=132m^2

CAN YOU ADD 0 TO PI TO GET A RATIONAL NUMBER
KiRa [710]

Answer:

No

Step-by-step explanation:

I am not sure what you mean by "add 0 to pi" as when you add 0 to anything, nothing changes. When you add anything to pi, in fact, you will never get a rational number. Even if you add an irrational number to pi to try and balance it, pi is infinite and will never be rational when something is added to it.

P = 3t² + 7t<br> Work out the value of P when t = -4
Tanzania [10]

Answer:

P = 20

Step-by-step explanation:

Hello!

We can solve this by substituting -4 for t.

<h3>Evaluate</h3>
  • P = 3t² + 7t
  • P = 3(-4²) + 7(-4)

<u>Remember that any negative number squared is the absolute value of that number squared.</u>

  • P = 3(|-16|)  - 28
  • P = 3(16) - 28
  • P = 48 - 28
  • P = 20

The final evaluation is 20.

I need help. Part A: Create a five-number summary and calculate the interquartile range for the two sets of data. (5 points)
Dahasolnce [82]

Five number summary and IQR of both the data sets are different.

For school A: Minimum=6, Q₁=6.5, Median= 14, Q₃=16, Maximum=17, IQR=9.5

For school B: Minimum=5, Q₁=8, Median= 12, Q₃=15.5, Maximum=19, IQR=7.5

No, the box plots are not symmetric.

Part A:

The given data sets are

School A : 9,14,15,17,17,7,15,6,6

School B : 12,8,13,11,19,15,16,5,8

Arrange the data in ascending order.

School A : 6,6,7,9,14,15,15,17,17

School B : 5,8,8,11,12,13,15,16,19

Divide each data set into four equal parts.

School A : (6,6),(7,9),14,(15,15),(17,17)

School B : (5,8),(8,11),12,(13,15),(16,19)

For school A:

Minimum=6, Q₁=6.5, Median= 14, Q₃=16, Maximum=17

The interquartile range of the data is

For school B:

Minimum=5, Q₁=8, Median= 12, Q₃=15.5, Maximum=19

IQR=Q_3-Q_1\\     =Q_3-Q_1\\     =16-6.2\\     =9.5

The interquartile range of the data is

IQR=Q_3-Q_1\\     =Q_3-Q_1\\     =15.5-8\\     =7.5

Part B:

The box plots are not symmetric because the data values are different. Five number summary and IQR of both the data sets are different.
