pyramid A: 16 + 8\sqrt{5

pyramid B: 400 + 8\sqrt{125

pyramid A: 4 by 4= 16 cm.

with a height of 1 and length of 2, we use pythagorean theorem to find height of other surfaces to be square root of 5. area of triangle is 1/2 bh

square root of 5 multiplied by 4 and divided by 2 is 2 root 5

multiply this by 4 sides total for 8 root 5

Add the 8 root 5 to 16

To find pyramid B: use ratio of 25:1 and multiply 16 by 25 to find 400, and root 5 to 125

What is the standard deviation of the data set given below? 2,6,7,10,10
Masja [62]
Average = (2 + 6 + 7 + 10 + 10)/5 = 35/5 = 7

x - mean,  square.

2 - 7 = -5,  -5² = 25

<span>6 - 7 = -1,  -1² = 1
</span>
<span>7 - 7 = 0,  0² = 0
</span>
<span>10 - 7 = 3,  3² = 9
</span>
<span>10 - 7 = 3,  3² = 9
</span>
Sum of square = 25 + 1 + 0 + 9 + 9 = 44
 
Variance = 44/5 = 8.8

Standard deviation = √variance = √8.8 ≈ 2.966

Anna11 [10]

Answer:

x = 2.5

Step-by-step explanation:

The arc length x is calculated as

x = circumference of circle × fraction of circle

  = 2πr × \frac{2.5}{2\pi } ( cancel 2π on numerator/ denominator )

x = 1 × 2.5 = 2.5
