<span>I am assuming the gender of each child is independent of the other.
Then the information about the first three children is irrelevant.
So then the probability of fourth child being boy is 1/2, since </span><span>boys and girls are equally likely</span><span>.
Hope this helps.</span>
Answer:
2(x+4) + 2(2x-7) = 42 ( If this is wrong simplify this)
Step-by-step explanation:
The formula for perimeter is (2 x length) + (2 x width), so our equation would be 2(x+4) + 2(2x-7) = 42
Using proportions, supposing a scale of 1 inch = 3 feet, the actual measurements of her bed are given by: 9 ft x 18 ft.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations such as multiplication or division, from the relations built in the problem.
One example of application of proportions is for scale problems, as the actual scale and the drawing length are compared to find the actual length of the object drawn.
In the context of this problem, the scale is given by:
1 inch = 3 feet.
The drawn length of the bed is given by:
3 inches x 6 inches.
Hence the actual length is given by:
9 feet x 18 feet.
As:
<h3>What is the missing information?</h3>
The scale of the drawing is missing, hence we are going to suppose that it is 1 inch = 3 feet.

Answer:
-19
Step-by-step explanation:
f(x) is the same as solving for the variable y
So y= -4(7)+9
f(7)= -28+9 = -19
