Answer:

Step-by-step explanation:

We have to construct a frequency distribution table using 7 classes.

1. Find the difference between the maximum wind speed and the minimum wind speed first.

93 - 48 = 45

2. Divide this difference by number of class.

\frac{45}{7} = 6.42

3. Round up this number.

6.42 ≈ 7

4. Add this number to the lowest number in the given table.

48 + 7 = 55

5. By repeating this step we can get 7 classes.

48

48 + 7 = 55

55 + 7 = 62

62 + 7 = 69

69 + 7 = 76

76 + 7 = 83

83 + 7 = 90

These are the lower limits of the interval.

6. Now we will write down the upper limits of the intervals.

48 + ( 7 - 1) = 54

48 - 54

Similarly we can write all other intervals.

55 - 61

62 - 66

67 - 73

74 - 80

81 - 87

88 - 94

7. Now we can easily form the frequency table.

Wind speed     Number of states

48 - 54                       3

55 - 61                        4    

62 - 66                       5

67 - 73                       12

74 - 80                       12

81 - 87                         3

88 - 94                        1

I didn’t learn about this can you help me with this
arlik [135]
If you're taking trig, the "sum and difference formulas for trig functions" are basic facts that you'll need to learn and commit to memory.  I'd suggest you look up these formulas on the net.  You will likely immediately find listings for the sine, cosine and tangent.

The volume of a right triangular prism is 72 cubic feet. The height of the prism is 9 feet. The triangular base is an isosceles
Mariulka [41]

Answer:

Step-by-step explanation:

volume = area of base * height = area of base * 9 = 72

-> area of base = 72/9 = 8

let a,b,c be the length of sides of isosceles right triangle base

we have a = b and a*b/2 = 8 ft2

-> a*a/2 = 8ft2

-> a*a = 16

-> a=4ft=b

have c^2 = a^2 + b^2 = 16 +16 = 32

-> c = \sqrt{32} = 5.656 ft

Since i dont know that is DF, i calculate both a,b and c
