After becoming sick, a patient sees a doctor who determines the most likely cause is an allergic
reaction and prescribes an antihistamine. The patient returns home and stops burning candles and
incense for the next week while taking the medication. By the end of the week, the patient is feeling
better and is telling all his friends how wonderful the medication was at relieving his symptoms. This
is an example of
1. confounding, as there is no way to tell whether it was the medication that alleviated his
symptoms
2. convenience sampling since he only stopped burning candles and incense because it was easy
3.a double-blind experiment since neither he nor the doctor really knew what was wrong
4. bias since he wanted to feel better
Answer:
I think it is 1, but I am not 100%
Step-by-step explanation:
Since he stopped the meds at the same time he stopped what couldve been his cousin his reaction to begin with, you can prove if it was medication only.
A field hockey field is rectangular. Its width is 54.88 meters, and its perimeter is 289.76 meters. Find the length of the field.
Answer:
90 PLEASE MARK ME BRAINLLIEST
Step-by-step explanation:
289.76-54.88-54.88=180/2=90
Perimeter is the sum of the length of the sides used to make the given figure. The length of the field is 90 meters.
What is the perimeter?Perimeter is the sum of the length of the sides used to make the given figure.
Given that the width of the field is 54.88 meters and the perimeter of the field is 289.76 meters. Therefore, we can write the perimeter as,
Perimeter = 2(Length + Width)
289.76 meters = 2(Length + 54.88 meters)
289.76meters / 2 = Length + 54.88 meters
144.88metes = Length + 54.88 meters
Length = 144.88 meters - 54.88 meters
Length = 90 meters
Hence, the length of the field is 90 meters.

A scooter travels 30 feet in 2 seconds at a constant speed.
The distance the scooter travels in 1 second is
feet. The distance the scooter travels in 3 seconds is
feet. The distance the scooter travels in 4 second is
feet. The distance the scooter travels in 5 second is
feet.
Answer:
The scooter travels 15 feet in 1 second
The scooter travels 45 feet in 3 seconds
The scooter travels 60 feet in 4 seconds
The scooter travels 75 feet in 5 seconds
Step-by-step explanation:
First, let's find the number of feet the scooter travels in 1 second
(30 : 2) ÷ 2 = 15 : 1
Now that we have the unit rate, we can easily find the answers to the other questions.
(15 : 1) x 3 = 45 : 3
(15 : 1) x 4 = 60 : 4
(15 : 1) x 5 = 75 : 5

It takes four workers six hours and 45 minutes to plant 24 trees. If the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers, how many trees could 9 workers plant in four and a half hours?
Answer:
36 trees
Step-by-step explanation:
We are told that It takes four workers six hours and 45 minutes to plant 24 trees. Also that the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers.
Thus,
t ∝ x/n
Where;
x is number of trees
n is number of workers
Now, opening the proportion symbol, we have;
t = kx/n
Where k is the constant of proportionality.
t = 6 hours 45 minutes = 6¾ hours = 6.75 hours
Plugging in the relevant values, we have;
6.75 = 24k/4
k = 4 × 6.75/24
k = 1.125
Now, we want to know how many trees could 9 workers plant in four and a half hours (4.5 hours)
Applying the same as above and Plugging in k = 1.125, we have;
4.5 = 1.125x/9
x = 9 × 4.5/1.125
x = 36 trees

A state gets it money from a state lottery, a property tax, a sales tax of 5%, and an excise tax. This year it projects that it will receive $24 million from the state lottery, $32 million from the property tax, and 14 million from the excise tax. If the state needs $100 million to cover it's expenses, how many dollars worth of taxable items must be purchased in the state this year for the state to break even?
A. $600,000,000
B. $150,000,000
C. $1,500,000
D. $ 30,000,000
Answer:A
Step-by-step explanation:
The items of worth $600,000,000 should be purchased in the state to meet the requirement, the correct option is A.
What is an Equation?An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.
The state has predicted to get $24 million from the state lottery,
The amount from property tax is $32 million
The amount form excise tax is $14 million
The state needs $100 million to cover its expenses
A sales tax of 5% is charged by the state
Let the total sales is $x in million dollars then the equation that can be formed is
24 + 32 +14 +(5/100 ) * x = 100
70+ (5/100 ) * x = 100
(5/100 ) * x = 100 -70
(5/100 ) * x = 30
x = 30 * 100 / 5
x = $600,000,000

C.
4m – 15 ≥ 35
D.

Inequality shows a relationship between two numbers or two expressions.
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is
15 + 4m ≥ 35
What is inequality?It shows a relationship between two numbers or two expressions.
