Researchers used two footballs of the same size to examine the effect of helium on kicking distance. One football was filled with air, and the other was filled with helium. Eleven people participated in the study. Each person kicked the football filled with air and the football filled with helium, and the kicking distances, in yards, were recorded. The football that was kicked first was determined by the flip of a fair coin, and the people did not know which football was filled with air and which was filled with helium. What type of study was conducted by the researchers and, of the following, which is the appropriate t-interval for inference?.

Answer:
c = 9
Step-by-step explanation:
You're looking for a number so that when you use that number in place of x, you end up with 20.
f(x) = 3x - 7
f(c) = 3c - 7
20 = 3c - 7
Add 7
27 = 3c
Divide by 3

Answers
Answer:
5x5x5x5
Step-by-step explanation:
The expression that has the same value as [tex]5^4[/tex] is 25² or 625.
What are Exponents and powers?Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner.
The number of times a given integer is multiplied by itself is represented as an exponent.The expression obtained by multiplying a number by itself n times is known as the nth power of the supplied integer.We have [tex]5^4[/tex].
Usually exponents can be expand using the number the power is raised.
As, if we have 9³ then it means 9 is multiplies by itself three times.
So, 9³ = 9 x 9 x 9= 729
Now, we have to expand [tex]5^4[/tex] as
= 5 x 5 x 5 x 5
= 5² x 5²
= 25 x 25
= 25²
= 625
So, the Equivalent value to [tex]5^4[/tex] is 25² or or 5² x 5² or 625.

Whole numbers are 'counting numbers', they don't include decimals. (ex. 1, 2, 3) Integers are non-decimal numbers and they can be negative too. (ex. -5, 0, 4). Since whole numbers are non-decimal numbers that are greater than or equal to 1, they are all integers. So this statement is False.
Rationals numbers include all numbers that are not infinite decimals. They can be fractions as long as they are not infinite and since whole numbers cannot be fractions, this statement is True.
As with the previous statement, rational numbers can be fractions and integers cannot be fractions. So, not all rational numbers are integers so this statement is False.
Rational numbers are all numbers that are not infinite decimals, so, that includes whole numbers. This statement is also True.

Detailed answers only please.
Answers
There are a couple of different ways we can do this: change the fraction into a decimal or multiply by the reciprocal.
Change the Fraction Into a Decimal
---3/4 = 0.75
So, instead of using the fraction, we can put it into decimal form. We will need to move the decimal point in both numbers though, making our division problem as follows:
20096 / 75 = ?
---The decimal point was moved two places to the right in order to make the former fraction a whole number.
Multiply by the Reciprocal
---To find the reciprocal, switch the numerator and denominator, essentially "flipping" the fraction upside down.
Another way of dividing by fractions is multiplying by the reciprocal. For example, dividing a number by 3 is the same thing as multiplying by 1/3. We can do the same in this problem. Instead of dividing by 3/4, we can multiply by 4/3, making our problem look as follows:
200.96/1 x 4/3 = ?
Answer: 803.84 / 3 = 267.9467

In quadrilateral two angles are equal. The third angle is equal to the sum of the two equal angles. The fourth angle is 60degrees less than twice the sum of the other three angles. Find the measures of the angles in the quadrilateral.
Answers
Answer: 35, 35, 70, and 220
Step-by-step explanation:
– Let x = size of one of the two equal angles
The sum of angles in a quadrilateral is 360:
360 = x+ x + ( x+x ) x (2( x+ x+ x+x ) – 60)
360 = 4 + 2(4 ) – 60
360 = 4 + 8 – 60
360 = 12 – 60
12x = 420
= 35
Substituting x for 35, will get: 35, 35, 70, 220
The values of the angles are 35°, 35°, 70° and 220°

What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
A unit circle is shown.
A radius with length 1 forms angle θ in the first quadrant.
Then the sin θ is equal to the negative one. Then the value of the θ will be
sin θ = -1
Then it can be written as
θ = sin⁻¹ (-1)
θ = 3π / 2
Thus, the correct option is C.
