Answer:
x = 1.2
Step-by-step explanation:
AD/AB = DE/BC (Similarity Theorem)
AD = 6 + 4 = 10
AB = 6
DE = 2
BC = x
Plug in the values
10/6 = 2/x
Cross multiply
10*x = 2*6
10x = 12
Divide both sides by 10
x = 12/10
x = 1.2
Answer:
17
Step-by-step explanation:
Answer:
part A: Mean:6.42 Median:7
Part b: median
Part c: no it’s skewed left and unimodal
Step-by-step explanation:
Let, the number be "a"
Now, according to the question,





So, the number is 72
Sin∠R = ST/RS ⇒ ST = RS * sin40° = 9 * 0.6428 ≈ 5.8
