The all possible eight outcomes of boy or girl birth when a couple have three children is
(GBB) , (GBG), (GGB) , (GGG), (BBG), (BGB), (BGG), (BBB)
Where B represents boy and G represents Girl
The probability that having exactly 1 girl is
= Number of outcomes with one girl / Total numbers of outcomes
Now Number of outcomes with only one girl = GBB, BGB, BBG = 3
So the probability will be
The probability that having exactly 1 girl is = 3/8 = 0.375
The probability that when a couple has three children, there is exactly 1 girl is 0.375
Answer:
13.50 is the answer
Step-by-step explanation:
40.50/3=13.50
Answer:
• Shift 5 units to the left >>> f(x) = |x+5|
• Shift 4 units down >>> f(x) = |x| - 4
Step-by-step explanation:
If we have the parent function:
f(x) = |x|
<u>For horizontal translations:</u>
- |x-a| means horizontally translated a units right
- |x+a| means horizontally translated a units left
<u>For Vertical translation:</u>
- |x| + b means vertically translated b units up
- |x| - b means vertically translated b units down
From the translation rules, we can say:
Shift 5 units left would be:
|x+5|
and
Shift 4 units down would be:
|x| - 4
Answer:
596.0 ft
Step-by-step explanation:
The relationship between the two legs of a right triangle and an acute angle is ...
Tan = Opposite/Adjacent
The height (h) of the lighthouse is the side opposite the angles of elevation. If d is the distance between A and B, we can write two tangent relations:
tan(14°) = h/770
tan(8°) = h/(770 +d)
Equating expressions for h gives ...
770·tan(14°) = (770 +d)·tan(8°)
770(tan(14°) -tan(8°)) = d·tan(8°) . . . . subtract 770·tan(8°)
d = 770·(tan(14°)/tan(8°) -1) . . . . . divide by the coefficient of d
d ≈ 770·(1.7740609 -1) = 596.03
The distance from point A to point B is about 596.0 feet.
