A family visits a car show to research information on vehicles they might consider purchasing. Brochures for each vehicle provide helpful information for the vehicle. Which of the following is an example of a continuous quantitative variable that might be included in the brochure?
number of seats
type of transmission
presence of a sunroof
fuel efficiency (in mpg)
An example of a continuous quantitative variable that might be included in the brochure is; A: number of seats
What is the continuous quantitative variable?Quantitative continuous variables are defined as the variables whereby their values are uncountable while also having a number of possibilities that are infinite.
A discrete quantitative variable is a variable that can be counted. This means that they are written in units whereby numbers will be counted and can be assigned.
From the question, the number of seats that are inside the car are countable. Thus, it can be evaluated based on its numerical value, instead of quality. In short, we can even say that the buyers were of the opinion that the more the number of seats that were in the car, the more the number of people the car was able to carry. Thus, we can conclude that the family would love to buy a car that has a reasonable number of seats.
Thus, we can conclude that the type of the transmission is a qualitative variable.

The linear regression model y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold.
Using the model, approximate the temperature when there are 95 ice cream cones sold. Round your answer to the nearest tenth. When they sell 95 ice cream cones, the temperature is approximately _ °F.
Answer:
95.5 °F
Step-by-step explanation:
A linear regression model is used to represent the relationship between two variables in form of a linear equation. A linear regression line equation is in the form Y = a + bX, where X is the independent variable, Y is the dependent variable, b is the slope of the line and a is the Y intercept (the value of y when x = 0).
Given that x represents the temperature (°F) and y represents the number of ice cream cones sold.
We have the equation as y = 1.8x - 76.9.
Given a 95 ice cream cones sold, to find the temperature, we substitute y = 95 and find x:
y = 1.8x - 76.9
95 = 1.8x - 76.9
1.8x = 95 + 76.9
1.8x = 171.9
x= 95.5 °F
When they sell 95 ice cream cones, the temperature is approximately 95.5 °F

if √7-3√5 = √x-√y, determine the value of x and y where x>y.
Answer:
x = 45
y = 7
Step-by-step explanation:
To obtain the value of x and y, do the following:
√7 – 3√5
Rearrange
– 3√5 + √7
Multiply through by –1
3√5 – √7 ... (1)
Express 3√5 as a single surd
3√5 = √(3 × 3 × 5)
3√5 = √45
Replace 3√5 with √45 in equation 1
3√5 – √7
√45 – √7
Comparing
√45 – √7 and √x – √y i.e
√45 – √7 = √x – √y
x = 45
y = 7

Why negative ( - ) sign is cannot be pulled out of square root.???
To show the negative of a square root, a negative sign would have to be placed outside the radical.
Answer:
Step-by-step explanation:
Because √-1 is an imaginary number √-1=i
They are imaginary because there are no same real numbers multiplyed that gives you a negative number
√4 = √2*2 ( +2*+2 =+4)
√4 = √-2*-2 (-2*-2 =+4)
√-1 = √? *? ( what same numbers multiplied gives you negative?...an imaginary one)

What are the slope and the y-intercept of the linear function that is represented by the equation Y--103-12
The slope is -10, and the y-intercept is -1.
The slope is -10. and the y-intercept is 1
The slope is -1, and the y-intercept is -10.
The slope is 1, and the y-intercept is -10.
Save and Exit
Answer:
The slope is -10, and the y-intercept is -1.
Step-by-step explanation:
The linear function is [tex]y=-10x-1[/tex].
The general form of a line is [tex]y=mx+c[/tex]
where
m = Slope of the line i.e., change of altitude divided by the change of the horizontal.
c = y intercept of the line i.e., the point where the line intersects the y axis.
Comparing with the given equation we get
[tex]m=-10[/tex] and [tex]c=-1[/tex]
So, the slope is [tex]-10[/tex], and the y-intercept is [tex]-1[/tex].
