back negative if a patient has the disease?
A. 65% of the time
B. 45% of the time
C. 55% of the time

100 - 45 = 55
So, it will come back negative 55% if a patient has the disease.

Which expression is equivalent to 15c+20?
Answer:
5 (3 c + 4)
Step-by-step explanation:
We factor out the 5, to get 5(3c+4)
We check by distributing the 5, and we get 15c+20 which is correct!
Hope this helps
The expression equivalent to 15c + 20 is 5(3c + 4).
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 15c + 20.
We have to find an equivalent expression of this using the distributive property.
For three numbers or expressions a, b and c, Distributive property states that,
a (b + c) = ab + ac
In the expression of 15c + 20, write each terms as a multiple of a common factor.
15c = 5 × 3c
20 = 5 × 4
15c + 20 = (5 × 3c) + (5 × 4)
= 5 (3c + 4)
Hence the correct expression which is equivalent to the given expression is 5 (3c + 4).

how could you use 1/8 measuring cup to measure 1/4 cups of water
We can use 1/8 measuring cup two times.
What is measurement?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
A cup of measurement 1/8.
Now,
we have to measure 1/4 from the cup using cup of measurement 1/8.
So, we can measure it two times.
as, 1/8+ 1/8
= 2/8

Step-by-step explanation:
the 5 is in the thousandths place so the whole decimal number ends with thousandths
three hundred and forty five and sixty five thousandths is the word for, for 345.065.
Since the period is on the 5 thousand’s place, you cancel all other number lower then 5 thousand like 60 and 5.
Difficult Math. Up to the challenge?
Answer:
We have the three angles of a triangle as an equation, so we can add them together, and they equal 180.
So:
4x+10+12x-6+3x+5= 19x+9=180
19x=171 ... so: x= 171/19 = 9.
So ABC = 102 .. Obtuse angle
BAC = 46 .. Acute angle
BCA = 32 .. Acute Angle
Edit:
Angle 1 = 180 - BAC = 180 - 46 = 134
Angle 2= 180 - ABC = 180 - 102 = 78

3 is what percent of 75?
Answer:
4%
Step-by-step explanation:
First, we turn this into a fraction:
3/75 = 1/25 = 4%
So 3 is 4% of 75
Using the percentage expression 4 percent of the number 75 is 3.
We have,
Given percentage = M
Under the condition, an expression can be written as,
M% of 75 = 3
Solve for M.
M/100 x 75 = 3
Multiply 100 on both sides.
75M = 3 x 100
75M = 300
Divide 75 on both sides.
M = 300/75
M = 4
Cross checked.
4% of 755
4/100 x 75
4/4 x 3
1 x 3
3
True.
Thus,
4 percent of number 75 is 3.

For the class picnic, 25 liters of punch were purchased. 6 liters were left over. How many gallons of punch were used at the picnic? (1 liter is approximately 0.26 gallons)
Answer:
Gallons of punch used = 4.94 gallons
Step-by-step explanation:
Given that:
Liters of punch purchased = 25 liters
Liters of punch left over = 6 liters
Liters of punch used = 25 - 6 = 19 liters
According to the given statement;
1 liter = 0.26 gallons
19 liters = 0.26*19 gallons
19 liters = 4.94 gallons
Hence,
Gallons of punch used = 4.94 gallons
In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 498 mL. The reserve and residual volumes of air that remain in the lungs occupy about 1990 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time.
Answer:
The model is [tex]V(t)=2239+249\sin(\frac{\pi}{2}t)[/tex].
Step-by-step explanation:
Consider the given information.
The volume of air inside the lungs increases or decreases so for this we will use the basic sine function [tex]B(t)=d+a\sin[b(t+ \frac{c}{a})][/tex] as our parent function.
Let us assume that the phase shift is 0 it means [tex]\frac{c}{b}=0[/tex].
The air that moves into and out of the lungs is about 498 mL.
It means the amplitude of the function will vary by 249(half of 498).
The reserve and residual volumes of air that remains in the lungs occupy about 1990 mL which is the minimum air in the lungs.
So, the max air will be: 1990+498 =2488 mL
And the average will be d=1990+249=2239 ml
The horizontal stretch will be [tex]b=\frac{2\pi}{4}=\frac{\pi}{2}[/tex] as we know that period of [tex]y=\sin t[/tex] is [tex]2\pi[/tex] and respiratory cycle for an average human takes about 4 seconds.
Hence, the model is [tex]V(t)=2239+249\sin(\frac{\pi}{2}t)[/tex].
