Mean can be found by adding up all of the numbers and then dividing that by a number of numbers.
2 + 3 = 5
5 + 5 = 10
10 + 8 = 18
18 + 8 = 26
26 + 0 = 26
26 + 2 = 28
So our outcome is 28. Since we have 7 numbers in the stem and leaf plot we have to divide 28 by 7.
28 ÷ 7 = 4
So your answer is 4!
Hope this helped. Have a great day!
Answer: y = ax2 + bx + c
looks like a slightly trick question...
y = ax2 + bx + c is the standard form...
y = a(x - h)2 +k is the graphing form
Step-by-step explanation:
P = 2(l+w)
Let x be the width.
130 = 2(x+(x+7))
130 = 2x + 2x + 14
116 = 4x
x = 29
The width of the rectangle is 29.
Answer:
About 36.43% of tomato plants have a height between 2.98 feet and 3.48 feet.
Step-by-step explanation:
1. Calculate the z-scores for 2.98 & 3.48 using the Z-Score Formula: -2.32 & -.32
2.Using the z-table, find the areas for both and change the decimals to percents: 1.02% & 37.45%
3. Subtract 1.02 from 37.45 to get the answer: 36.43%
