Answer:
34.93
Step-by-step explanation:
Ok, so using the formula for a trapezoid, you would get that Jim's garden's area is equal to 135.
Since each grass bag can cover 20m of the garden,
135/20=6.75
You would need seven bags because you can't buy 6.75 bags at a store.
Since each bag of grass seed is 4.99, 7*4.99 = 34.93.
I'm doing this in dollars, so I'm assuming that one pound is 100 cents or something like that.
Answer:
Standard deviation = 14.064
Step-by-step explanation:
We are given the following data;
X X -
20 20 - 46 = -26 676
23 23 - 46 = - 23 529
32 32 - 46 = -14 196
36 36 - 46 = -10 100
41 41 - 46 = -5 25
43 43 - 46 = -3 9
44 44 - 46 = -2 4
45 45 - 46 = -1 1
47 47 - 46 = 1 1
54 54 - 46 = 8 64
55 55 - 46 = 9 81
59 59 - 46 = 13 169
61 61 - 46 = 15 225
63 63 - 46 = 17 289
66 66 - 46 = 20 <u> 400 </u>
<u>= 2769 </u>
Firstly we will calculate Mean,
=
= 45.93 ≈ 46
Now, Standard deviation formula is given by;
s =
=
= 14.064 .
Answer:
76.107 rounded to the nearest tenths is 76.1.
Step-by-step explanation:
Since the line is going from the top left to the bottom right, the slope is negative so A and B are possible answers.
the line crosses the y axis at -1
B is the option that ends with -1
therefore your answer is B. y = -2x - 1
