Answer: 2.6
Step-by-step explanation:
Step 1: Calculate the mean of Shade's plant heights.
= 7+12+12+8+9+8+8+8/8
= 72/8
=9
Step 2: Calculate the range of Shade's plant heights. Range is highest minus lowest number. This will be:
12 - 7 = 5
Step 3: Calculate the mean of Sun plant heights.
19+24+20+23+24+23+23+20/8
= 176/8
= 22
Step 4: Find the range of Sun plants height.
= 24 - 19 = 5
Step 5: Find the difference of means
= 22 - 9
= 13
Step 6: Divide the difference of means by the range.
= 13 ÷ 5
= 2.6
You do 2067 - 86 = 1981 :)
Answer:
16
Step-by-step explanation:
This is due to the rule that all shapes exterior angles add to 360.
Therefore 360 = 46 + 3x +62 + 4x + 47 + (180-83)
360 = 248 + 7x
7x = 112
x= 16
Answer:
Step-by-step explanation:
Answer:
6 and 4
Step-by-step explanation: since it is "cm2" it means it was already halved. This means that the answer was originally 24, 6x4 is the only one that equals 24.
