Answer:
P=1/42.
Step-by-step explanation:
We know that the student council has 10 members where 5 of the members are Seniors. They need to choose a President, Vice President, Secretary and Treasurer. We calculate the probability that the President is a Senior:
We calculate the number of possible combinations:
Number of favorable combinations is 5.
Threfore, the probability is
P=5/210
P=1/42.
Answer:
+12+8＝+20

Hello there!
The additive inverse of any number just means to flip it's value.
For example;
The number "3" would have an additive inverse of "-3".
The number "-15" would have an additive inverse of "15".
Since we have "52", we can flip the value sign of it.
We now have -52 and 52.
Since the question asked us to sum our numbers, we need to add them.
-52 + 52 = 0
The sum of 52 and its additive inverse is 0.
I hope this helps!
Answer:
Solution given:
f(x)=x²
g(x)=x+5
h(x)=4x-6
now
23:
(fog)(x)=f(g(x))=f(x+5)=(x+5)²=x²+10x+25
24:
(gof)(x)=g(f(x))=g(x²)=x²+5
25:
(foh)(x)=f(h(x))=f(4x-6)=(4x-6)²=16x²-48x+36
26:
(hof)(x)=h(f(x))=h(x²)=4x²-6
27;
(goh)(x)=g(h(x))=g(4x-6)=4x-6+5=4x-1
28:
(hog)(x)=h(g(x))=h(x+5)=4(x+5)-6=4x+20-6=4x-14
