Answer: segment BC = 36 units
Step-by-step explanation:
As per the given information, we have
B, C and D are three points such that
segment BC = segment BD + segment DC ... (i)
And segment BD = segment DC ... (ii)
If segment BD = 18 units
Then, segment DC = 18 units [From (ii)]
segment BC = 18 units + 18 units [From (i)]
⇒segment BC = 36 units
Hence, length of = 36 units
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!
