The height of the green pyramid constructed by Natalie while playing with magnetic building tiles is 26.25 cm.
<h3>
Volume of the orange pyramid</h3>
The volume of the orange pyramid is calculated as follows;
V = ¹/₃Ah
where;
- A is the base area of the pyramid
- h is the height of the pyramid
V = ¹/₃ x (7²) x 5
V = ¹/₃ x (245 cm³)
<h3>
Volume of the green pyramid</h3>
Voume = 21 x [¹/₃ x (245 cm³)]
Volume = 1,715 cm³
<h3>Height of the green pyramid</h3>
V = ¹/₃Ah
3V = Ah
h = 3V/A
h = (3 x 1715) / (14²)
h = 26.25 cm

Answer:
last one
a = 30 + 5
a - 5 = 30
Step-by-step explanation:
here is your answer
Answer: 91 guests
Step-by-step explanation:
Given the available furniture legs to be 364, where each seat has 4 legs
We will divide 364 by 4 to get the number of available seats.
364/4 = 91 seats
If 91 seats are available and it is set at 1 seat per guest,
Number of guests will be 91 seats/1 = 91, therefore, 91 guests will be available.
Answer:
64k^2 - 16k +1
Step-by-step explanation:
We can rewrite this as
(-8k+1) ^2
We know that (a+b)^2 = a^2 +2ab +b^2
Let a = -8k and b = 1
(-8k+1) = (-8k)^2 +2*(-8k)(1) + 1^2
=64k^2 - 16k +1
Answer:
The data provide sufficient evidence that older people are more likely to be victimized.
Step-by-step explanation:
H 0 : P = 0.10
H 1 : P > 0.10 (Right tailed test)
n = 527, P = 0.1235
The test statistics
x = P - p / ![\sqrt{p*(1-p) / n}](https://tex.z-dn.net/?f=%5Csqrt%7Bp%2A%281-p%29%20%2F%20n%7D)
x = 0.1235 - 0.10 / ![\sqrt{0.10 * 0.90 / 527}](https://tex.z-dn.net/?f=%5Csqrt%7B0.10%20%2A%200.90%20%2F%20527%7D)
x = 0.0235 / ![\sqrt{0.09 / 527}](https://tex.z-dn.net/?f=%5Csqrt%7B0.09%20%2F%20527%7D)
x = 0.0235 / ![\sqrt{0.00017077798}](https://tex.z-dn.net/?f=%5Csqrt%7B0.00017077798%7D)
x = 0.0235 / 0.0130682049264618
x = 1.798257689731729
x = 1.798
P value = [1 - p(Z > 1.7980] (Right tailed test)
P value = 0.036089
The P - Value is very small, so <u>reject H0</u>
Conclusion: The data provide sufficient evidence that older people are more likely to be victimized.
