A linear regression was conducted on the number of cigarettes a person smokes in a day versus the number of times they cough in

a day. Suppose the number of cigarettes a person smokes in a day is our x variable and the number of times they cough in a day is the y variable.
In linear regression, the y variable is referred to as the:

a) response variable.
b) correlation coefficient.
c) explanatory variable.
d) true variable.

Answer:

a) response variable

Step-by-step explanation:

The response variable is the variable that depends on other variables such as the independent or explanatory variable, it is the variable that is being tested. The response variable is also called the dependent variable.

In linear regression, the y variable is referred to as the response variable while the x variable is referred to as the explanatory or independent variable.

In this case the y variable is "the number of times they cough in a day" and this variation depends on the x variable "number of cigarettes a person smokes in a day".

Find the arc length of AB. Round your answer to the nearest hundredth.
Fantom [35]

The arc length of AB is 8 m (app.)

Explanation:

Given that the radius of the circle is 8 m.

The central angle is 60°

We need to determine the arc length of AB

The arc length of AB can be determined using the formula,

arc \ length=\frac{central \ angle}{360^{\circ}} \times circumference

Substituting central angle = 60° and circumference = 2πr in the above formula, we get,

arc \ length=\frac{60^{\circ}}{360^{\circ}} \times 2 \pi(8)

Simplifying the terms, we get,

arc \ length=\frac{8 \pi }{3}

Dividing, we get,

arc \ length=8.37758041

arc \ length=8(app.)

Hence, the arc length is approximately equal to 8.

Therefore, the arc length of AB is 8 m

15) A new BMW decreases in value exponentially after it is purchased. If a new BMW is valued at $55,000 and
tia_tia [17]

The values of BMW after 2 years and 4 years  according to the EXPONENTIAL FUNCTION are $33,462 and $20,358.28

Using the parameters given, we define an decreasing exponential function :

A = A_{0} (1 - r)^{t}

Where,

A_{0} = initial amount ; r = Rate ; t = time ; A = final amount

Value after 2 years :

t = 2

A = 55000(1 - 0.22)²

A = 55000(0.78)²

A = $33,462

Value after 4 years :

t = 4

A = 55000(1 - 0.22)^4

A = 55000(0.78)^4

A = $20,358.28

Therefore, the value of BMW after 2 years and 4 years $33,462 and $20,358.28 respectively.

Which equation can be solved using the expression -3 plus or minus the square root of (3)^2+4(10)(2)/2(10) for x?
monitta

Answer: B. 2=3x+10x^2

Step-by-step explanation:

The expression means the quadratic function equation.

B = 10x^2 + 3x -2 = 0

the equation is [-b ±√(b^2 -4ac)]/2a

b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
