Use dimensional analysis. 1 lb = 16 oz will be the conversion factor. 162 oz x (1 lb/16 oz) = 10.125 lb.
5x^3 - 5x - 8 + 2x^3 + 4x + 2
7x^3 - x - 6 (some like terms)
Answer:
148 in^2
Step-by-step explanation:
2(4 x 5) = 40
2(4 x 6) = 48
2(5 x 6) = 60
Answer:
yes
Step-by-step explanation:
In a square, there are always two pairs of parallel sides, so every square is also a trapezoid. TRAPEZOID i said
But this is a US response so if this is from another country then the answer is no
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!
