Answer:
[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]
Step-by-step explanation:
Given
P = Test is positive
D = Disease is present
Required
Write an expression when disease is present but test says that the disease is not present
The above statement can be split to two
Disease is Present & Test is not positive
The first statement:
Disease is Present means D
The second statement
Test is not positive means not P
Mathematically;
not P means P' or [tex]P^c[/tex]
So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

If the width of a rectangle is 9 ft less then twice it’s length and the perimeter is 30 feet, what are the dimensions of the rectangle?
The dimension of the rectangle is,
The length of the rectangle is 7 feet.
And the width of the rectangle is 8 feet.
Given that,
If the width of a rectangle is 9 ft less than twice its length and the perimeter is 30 feet,
We have to determine,
What are the dimensions of the rectangle?
According to the question,
Let, the width of the rectangle is W,
And the length of a rectangle is L = 2W - 9,
The perimeter of the rectangle is = 2(L+W)
Where perimeter is 30 feet,
Therefore,
[tex]30 = 2(2W-9+W)\\\\30 = 2(3W-9)\\\\30 = 6W-18\\\\30 + 18 = 12W\\\\48 = 6W\\\\W = \dfrac{48}{6}\\\\W = 8 \ feet[/tex]
And the length of a rectangle is,
[tex]L = 2W - 9, \\\\L= 2(8) - 9\\\\L = 16-9 \\\\L =7 \ feet.[/tex]
Hence, The dimension of the rectangle is, the length of the rectangle is 7 feet, and the width of the rectangle is 8 feet.

Find the measure of angle A
Answer:
43°
Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10
[tex]m\angle A = (x +53)\degree \\\\
m\angle A = (-10 +53)\degree \\\\
m\angle A = 43\degree \\\\
