The least square regression line equation is y = a + bx, where y is the response variable (sepal width), x is the independent or predictor variable (sepal length), a is the intercept, and b is the slope of the line.

The equation for the least square regression line is y = a + bx, where y is the dependent or response variable, x is the independent or predictor variable, a is the intercept, and b is the slope of the line. To calculate the equation for the least square regression line when the independent or predictor variable is sepal length and the dependent or response variable is sepal width for iris versicolor, the following steps should be taken: First, calculate the mean of the sepal lengths and the sepal widths. Then, calculate the variance of the sepal lengths, and the variance of the sepal widths. Next, calculate the covariance of the sepal length and sepal width. Finally, calculate the slope (b) of the regression line using the formula b = covariance/(variance of x). Once the slope is calculated, substitute it into the regression line equation to calculate the intercept (a). Using the mean of the sepal lengths and the slope and intercept, the equation for the least square regression line for the given data set can be calculated.

Answer: x=7[tex]\sqrt{3}[/tex] and y = 14

Step-by-step explanation:

Answer:

i) x ≈ -0.2 or x ≈ 1.2

ii) x ≈ -0.5 or x ≈ 1.5

Step-by-step explanation:

y = 4x^2-4x-1

that means 4x^2-2-4x-1 can be also considered as y

so 4x^2-2-4x-1 = 0 can be considered as y = 0

same goes to 4x^2-2-4x-1 = 2  which is considered as y = 2

since y = 0 and y = 2

we draw a horizontal like at y = 0 and y = 2

then you can determine which points the blue drawn parabola touches the horizontal line drawn

the co-ordinates would be written in (x,y)

i) (-0.2,0) and (1.2,0)

ii) (-0.5,2) and (1.5,2)

If water is being poured into the trough at a rate of 5 ft^3/min, the rate at which the water level is rising when the depth is 8 inches is 15√3/32 ft/min.

Length (L) = 8 feet

Side = 2 feet

If water is being poured into the trough at a rate of 5 ft^3/min. So

dV/dt = 5 ft^3/min

The depth is 8 inches.

h = 8 inches = 2/3 feet

The formula of volume (V) = √3/4 b^2 · L

Now putting the value

V = √3/4 b^2 · 8

Simplify

V = 2√3b^2

Using the Pythagorean Theorem

b/h = 2/√3

So b = 2/√3 h

Now putting the value of h in the volume V

V = 2√3(2/√3 h)^2

V = 2√3 × 4/3 × h^2

V = 8/√3 × h^2

Differentiating the equation with respect to t

dV/dt = 8/√3 d/dt(h^2)

dV/dt = 8/√3 × 2h dh/dt

dV/dt = 16h/√3 × dh/dt

As dV/dt = 5. So

5 = 16h/√3 × dh/dt

Multiply by √3 on both side, we get

16h dh/dt = 5√3

Divide by 16h on both side, we get

dh/dt = 5√3/16h

As h = 2/3. So

dh/dt = 5√3/(16×2/3)

After solving

dh/dt = 15√3/32 ft/min

The equation of the line passing through the points (1,-5) and (3, -17) is y = -6x + 1.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,

Points are  (1,-5) and (3, -17)

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

m = -17 + 5 / 3 - 1

m  = -6

The equation of the line is given as

y - y₁ = m (x - x₁)

y + 5 = -6 (x -1)
y = -6x + 1

Step-by-step explanation:

The percent markup is 66.67%.

The markup is the difference between the cost price and the selling price of a product, expressed as a percentage of the cost price.

Let's call the cost price of each shirt "cp". Then, the total cost price of 200 shirts would be 200 * cp.

The selling price of each shirt is $20, so the total revenue from selling 200 shirts would be 200 * $20 = $4000.

From the information given, we know that the total cost price of 200 shirts is $2400.

Therefore, we can set up the following equation to find the cost price of each shirt:

200 * cp = $2400

Dividing both sides by 200, we get:

cp = $12

The markup is the percentage increase from the cost price to the selling price, so it can be calculated as follows:

Markup = (Selling Price - Cost Price) / Cost Price * 100%

= ($20 - $12) / $12 * 100%

= 66.67%

The value of z that satisfies the condition p(-z < z < z) = 0.7372 is 0.8614.

Given: p(-z < z < z) = 0.7372

We are trying to find the value of z that satisfies the above condition.

The given condition p(-z < z < z) means that the value of z lies in the interval (-z, z) such that the probability of this interval is equal to 0.7372.

To find the value of z, we need to use the properties of normal distribution.

If X is a standard normal random variable, then the cumulative distribution function (CDF) of X, denoted by Φ(x), is given by:

Φ(x) = P(X ≤ x) = 1/√2π ∫-∞x e^-t^2/2dt

So, for the given condition, we have:

p(-z < z < z) = Φ(z) - Φ(-z) = 0.7372

We can use a standard normal table or a calculator with the cumulative normal distribution function to find the value of z that satisfies the above equation.

After using the cumulative normal distribution function, we find that z = 0.8614.

Therefore, the value of z that satisfies the condition p(-z < z < z) = 0.7372 is 0.8614.

Ram obtained 680 marks in his examination.

We have to use the concept of percent-to-decimal conversion to solve this problem.

Ram scored 85% of the total marks, which was 800 of the total. To find the number of marks he obtained, we have to multiply 800 by 85% (0.85).

85% is equivalent to 0.85 when expressed as a decimal. To find the number of marks Ram obtained, we have to multiply the total marks (800) by 0.85,

After multiplying 800 * 0.85 = 680 marks.

The set of ordered pairs of A and C represents a linear function.

The graph of a linear function is a straight line. The following is the form of a linear function.

a + bx = y = f(x).

One independent variable and one dependent variable make up a linear function. x and y are the independent and dependent variables, respectively.

Given ordered pairs:

A (-2,8) (0,4) (2,3) (4,2)

B (1,2) (1,3) (1,4) (1,5)

C (-2,7) (0,12) (2,17) (4,22)

D (3,5) (4,7) (3,9) (5,11)​

The definition of a linear function is the relationship between input and output values.

Range refers to the set of output values, and domain refers to the set of input values.

The fact that an input value cannot have two different output values is the most significant attribute of functions (which defines them). Having stated so, observe how sets B and D include pairings that defy this rule.

The concept of instantaneous rate of change, also known as derivative, gives us the rate at which a quantity changes with respect to time at a specific instant. To find the instantaneous rate of change, we can take the derivative of the function that describes the position of the ball.

In this case, the position of the ball is given by the function f(x) = 2Vx, where V is the initial velocity of the ball. Taking the derivative of the function, we get the derivative as f'(x) = 2V, which represents the instantaneous rate of change of the ball's position with respect to time at any instant x.

When x = 9 seconds, the instantaneous rate of change of the ball's position is given by f'(9) = 2V. Therefore, the correct answer is d. 2/3V ft/sec.

The formula for calculating arc length is used to determine the length of the arc's curved line (a segment of a circle). The arc length is, to put it simply, the distance that passes across the curved line of the circle that forms the arc. Arc stability, weld current, and part concentricity are all factors that affect arc length. Arc stability, weld current, and part concentricity are all factors that affect arc length. The commercial welder's job in this situation is to maintain the electrode at a specific distance from the surface so that there is adequate room to prevent stubbing out.

The initial value problem for the concentration of salt in the tank over time will be: dc/dt = [(1 g/L * 2 L/min) - (c * 2 L/min)] / 2000 L

An initial value problem (IVP) in multivariable calculus is an ordinary differential equation with an initial condition that determines the value of the unknown function at a specific location in the domain. In physics or other sciences, modelling a system typically entails addressing an initial value issue.

Let's call the concentration of salt in the tank "c" (in grams/liter).

The initial concentration of salt in the tank is: c(0) = 400 / 2000 = 0.2 g/L

The rate of change of concentration with time "t" (in minutes) can be represented as:

dc/dt = (inflow rate of saltwater - outflow rate of saltwater) / volume of tank

dc/dt = [(1 g/L * 2 L/min) - (c * 2 L/min)] / 2000 L

This is the initial value problem for the concentration of salt in the tank over time.
