Answer:
m∡A = 14
m∡B = 76
Step-by-step explanation:
Two Angles are Complementary when they add up to 90 degrees.
So 3x -7 + 11x - 1 = 90, which we can solve.
14x - 8 = 90
14x = 98
x = 98/14 = 7
with the knowledge of x=7, we can find the angles:
m∡A = 3·7 - 7 = 14
m∡B = 11·7 - 1 = 76
Supplementary angles are angles that add up to 180 degrees, so the next assignment is very comparable, try it!
Answer:
hi, have a great day
Step-by-step explanation:
Correct option is
B
f(x)=x
2
+6
f(g(x))=h=4x
2
+4x+7=(2x+1)
2
+6=(g(x))
2
+6
⇒f(x)=x
2
+6
It would be j because you would subtract 25 because he sold 25 pieces then divide by 40 to find the number of piles
9-9 = 0 because there is no remainder
<span>P<span>(S∪T)</span>=<span>34</span></span>
Explanation:
We use the following fundamental definition from Probability and Set Theory:
<span>P<span>(A∪B)</span>=P<span>(A)</span>+P<span>(B)</span>−P<span>(A∩B)</span></span>
And if we apply this to our problem we have:
<span>P<span>(S∪T)</span>=P<span>(S)</span>+P<span>(T)</span>−P<span>(S∩T)</span></span>
<span> =<span>13</span>+<span>512</span>−P<span>(S∩T)</span></span>
<span> =<span>34</span>−P<span>(S∩T)</span></span>
Now we are told that S and T are mutually exclusive, and so:
<span>P<span>(S∩T)</span>=0</span>
Hence,
<span>P<span>(S∪T)</span>=<span><span>34</span></span></span>
