Step-by-step explanation:
P(heads) = ½, and P(tails) = ½
a) P(5 heads) = (½)⁵ = ¹/₃₂
b) P(5 tails) = (½)⁵ = ¹/₃₂
c) P(at least 1 head) = 1 − P(all tails) = ³¹/₃₂
Answer:
Step-by-step explanation:
This means that <C and <F are congruent.
So 2x - 15 = x + 15 Add 15 to both sides
2x-15+15=x+15+ 15
2x = x + 30 Subtract x from both sides
2x-x=x-x+30
x = 30

The second choice is the correct one.
Answer:
y=-5/2x+4
Step-by-step explanation:
find the slope by using y2-y1/x2-x1
-1-19/2-(-4)
simplify
-20/8
simplify
-5/2
use slope-intercept form, y=mx+b
since we know the slope, find b
plug in one of the ordered pairs into the equation
-1=(-5/2)(2)+b
simplify
-1= -10/2+b
simplify
-1=-5+b
add 5 to both sides
b=4
plug b into y=-5/2x+b
y=-5/2x+4
