Answer:
Area: 312
Perimeter: 75
Step-by-step explanation:
Area is l·w
20·16=320
two corners aren't filled
320-9-9=318
Add all the sides for perimeter
17+3+3+13+20+13+3+3=75
Answer:
281 m squared
Step-by-step explanation:
What we can first do is find the top length so we can do
17+3+3=23
then we can multiply it by the side length to get the whole rectangle
23*13=299
and we know each of the little areas is 9, and there are two so
9+9=18
and we can subtract that from the whole rectangle
299-18=281

Find the area of the shaded region.
help pls
Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm

Suppose 288 electricians took a certification test that is worth 140 points. The five-number summary for the scores is shown here.
min. value = 68
Q1 = 110
median = 125
Q3 = 130
max. value = 138
About how many electricians had a score of 110 or less? A: 72 B: 130 C: 144 D: 216
Answer:
72
Step-by-step explanation:
For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:
0.25 * 288 = 72.

Step-by-step explanation:
I will give brainiest please answer and explain nummber 3
Answer:
Part A: 56
Part B: 43.9
Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean
Step-by-step explanation:
Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.
Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.
Part C: explanation in answer.
Hope this helps :)
Answer:
for part a you can just go to an excel numbers in a column then click sum then click medien then select the column.

Step-by-step explanation:
Gabe goes to the mall. If b is the number of items he bought, the expression 17.91b+27 gives the amount he spent in dollars at one store. Then he spent 22 dollars at another store. Find the expression which represents the amount Gabe spent at the mall. Then estimate how much Gabe spent if he bought 4 items.
Answer:
(17.91b+27)+22 is the expression
and the estimate will be 121 because u will do 18 times 4=72 and the add 22 and then 27.

I am using the graphing calculator my school uses for exams. But here is the step by step anyway
5x + 36 = 2x + 96
(5x - 2x) + 36 = (2x - 2x) + 96
3x + 36 = 96
3x + (36 - 36) = (96 - 36)
3x = 60
(3x ÷ 3) = (60 ÷ 3)
x = 20
x represents weeks
