Hence, the volume of pyramid is:
3x^2 cm^3
<h3><u>
Step-by-step explanation:</u></h3>
We know that a volume(V) of a oblique square pyramid with height 'h' and base area A is given by the help of formula:
Now, according to the ques we have:
The base edge of an oblique square pyramid is represented as x cm.
The height is 9 cm.
Hence, the base area (A) is calculated as:
( Since the base is in the shape of a square and we know that the area of square with side length s is given as:
)
So, the volume of the pyramid is calculated as:
Hence, the volume of pyramid is:
3x^2 cm^3
Answer:
p-value: 0.453
Step-by-step explanation:
Hello!
You have two study variables
X~N(μₓ;σₓ²)
nₓ= 4
X[bar]ₓ= 149.50
Sₓ= 10.66
Y~N(μ;σ²)
= 6
X[bar]= 158.17
S= 19.87
The hypothesis is:
H₀: μₓ = μ
H₁: μₓ ≠ μ
The statistic to use is a pooled t for independent samples with unknown but equal population variances
t= [(X[bar]ₓ - X[bar]) - (μₓ - μ)]/[Sa/√(1/nₓ + 1/)]
The value of the statistic is:
t= -0.789
For this statistic value the corresponding p-value is:
P(t ≤ -0.789) + (1 - P(t ≤ 0.789) = 0.453
I hope it helps!
1) I'm guessing your question is x * x^3
the answer for that would be x^4
2) T^21
3) the answer is not reasonable as the sum of those 2 numbers is 354.94
4) -12x
