Sounds like a problem in binomial probability. What do you think?
Here the # of experiments is 6, so n = 6. The probability of a baby girl being born is 0.50.
Using my TI-83 Plus calculator:
binompdf(6, 0.5, 2) = 0.234
binompdf(6, 0.5, 3) = 0.313
binompdf(6, 0.5, 4) = 0.234
binompdf(6, 0.5, 5) = 0.094
binompdf(6, 0.5, 6) = 0.016
To get the prob. of at least 2 girls in 6 births, add up the 5 probabilities given above:
P(at least 2 girls in 6 births) = 0. ???
If fencing costs $5 per meter then the cost of fence to enclose the patio will be $ 120. Then the correct option is C.
<h3>What is a rectangle?</h3>
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
Shelley plans to enclose the patio with fencing.
The dimension of the patio is 12 meters by 6 meters.
Then the perimeter of the patio will be
Perimeter = 2 (12 + 6) - 12
Perimeter = 2 x 18 - 12
Perimeter = 36 - 12
Perimeter = 24 meters
If fencing costs $5 per meter.
Then the cost fence to enclose the patio will be
Cost = 5 x 24
Cost = $ 120

No,
5x means 5 is being multiplied by a number (x)
x+5 means that’s a number (x) is being added to 5
Hope this helps ;)
