Answer:
x = 7
Step-by-step explanation:
4x + 5 = x + 26
4x - x = 26 - 5
3x = 21
x = 21/3
x = 7
Check:
4*7 + 5 = 7 + 26
28 + 5 = 33
F(x)=2+5 power -x
2+5^ -2
=2.04
the answer is A.
Answer:
Correct

Answer:
Mathematically, two events are considered to be independent if the following relation holds true,
∵ P(B | A) = P(B)
For the given case,
P(D | L) = P(D)
But
0.13 ≠ 0.47
Since the relation doesn't hold true, therefore, "being left-handed" and "being a Democrat are not independent events.
Step-by-step explanation:
We are given that
Left-handed = P(L) = 0.40
Democrats = P(D) = 0.47
If a president is left-handed, there is a 13% chance that the president is a Democrat.
P(D | L) = 0.13
Based on this information on the last fifteen U.S. presidents, is "being left-handed" independent of "being a Democrat?

Step-by-step explanation:
90 nickels = 5*90=450=450/100=$4.5,
16 dimes=16*10=160=160/100=$1.6
16 quarters = 25*16=400=400/100=$4
7 fifty-cent pieces = 7*50=350=350/100=$3.5
Total dollars = 4.5+1.6+4+3.5=$13.6
