X= 5
To find the side a we will use the Pythagorean Theorem:
<span><span>a2</span>+<span>b2</span>=<span>c2</span></span>
After substituting <span>b=12</span> and <span>c=13</span> we have:
<span><span>a2</span>+<span>122</span>=<span>132</span></span><span><span>a2</span>=<span>132</span>−<span>122</span></span><span><span>a2</span>=169−144</span><span><span>a2</span>=25</span><span><span>a=5</span></span>
Answer:
Step-by-step explanation:
Given that you choose at random a real number X from the interval [2, 10].
a) Since this is a contnuous interval with all number in between equally likely
E = probability for choosing a real number is U(2,10)
pdf of E is 
b) P(X>5) = 

For

P(X<5 or x>7) = 1-P(5<x<7)
= 
Step-by-step explanation:
for a it's y=12x+60
for b it's y=1x+21
for c it would be) 40-70=-30/1-3=-2 and then divide -30/-2 is 15.
for d it would be y=20x+20
it would be ethier a or d
