This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!
Answer:
a. (b) 2.5
b. (b) 1.89
Step-by-step explanation:
E(X) =0(0.05)+1(0.25)+2(0.35)+3(0.15)+4(0.15)+5(0.15)= 2.5

Reason 5. ASA
Answer:
C) y = 2x + 3
Step-by-step explanation: You have to substitute 1 for x & 5 for y & 2 for m, but 1st do the point slope form ---> slope intercept form.
y -Y1 = m(x - X1)
y - 5 = 2(x - 1)
y - 5 = 2x - 2
+5 + 5
y = 2x + 3 --- IN SLOPE INTERCEPT FORM
Hope this helps you!!! :)
