3323.5 because if you times the number left by the 15 percent this is the answer.
We know the area of a small square is 24 in².
Assuming the small rectangles are all equal in area, the total area of the window is equal to 6 x 24 = 144 in².
Now looking at the big window, the total area = width x length so:
144 = 18 x width
width = 144 ÷ 18 = 8 in
The two angles form a straight line and need to equal 180 degrees
180 - 61 = 119
The missing angle is 119 degrees
<h3>
Answer: 35.2 cm</h3>
===============================================
Work Shown:
x = sum of all 6 lengths
x/6 = mean of the 6 lengths
x/6 = 44.2
x = 6*44.2
x = 265.2
All 6 lengths add up to 265.2 cm.
---------
y = sum of the first 5 lengths
y/5 = mean of those first 5 lengths
y/5 = 46
y = 5*46
y = 230
The first five lengths add up to 230 cm.
---------
z = length of the 6th rod, length is in cm
y+z = (length of first 5 rods)+(length of 6th rod)
y+z = x
230+z = 265.2
z = 265.2-230
z = 35.2
The sixth rod is 35.2 cm
Answer:
the first one is 23
the second one is 70-79
the third one is 11
Step-by-step explanation:
this is because frequency refers to the amount of people who got the scores on the x-axis.
so for the first one you would count up how many people participated i.e. 2+9+7+5 = 23
the second one is asking for the mode test score and mode refers to the most common, so the most common test score is the 70-79 bar
the third one is asking for how many people scored below 80, which is 11 as 2 people scored 60-69 and 9 scored 70-79 on the test (2+9=11)
Hope this helps :)
