What is the slope of the line that passes through the points (7, -4) and (7, 0)? Write your answer in the simplest form.
olga55 [171]

Answer:

The slop is undefined

i.e. m=\infty

Step-by-step explanation:

Considering the slope formula

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

As the points are (7, -4) and (7, 0)

Here:

  • (x₁, y₁) = (7, -4)
  • (x₂, y₂) = (7, 0)

\mathrm{When\:}y_1\ne \:y_2\mathrm{\:and\:}\:x_1=x_2\mathrm{\:the\:slope\:is\:}\infty

so

  \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

            =\frac{\left(0-\left(-4\right)\right)}{\left(7-7\right)}

             =\frac{0-\left(-4\right)}{0}

             =\infty    

Therefore, the slop is undefined i.e. m=\infty

The head of a computer science department is interested in estimating the proportion of students entering the department who wil
olya-2409 [2.1K]

Answer:

96

Step-by-step explanation:

From the given information:

At 95% Confidence interval level,Level of significance \alpha 0.05, the value of Z from the standard normal tables = 1.96

Margin of Error = 0.10

Let assume that the estimated proportion = 0.5

therefore; the sample size n can be determined by using the formula: n =(\dfrac{Z}{E})^2 \times p\times (1-p)

n =(\dfrac{1.96}{0.1})^2 \times 0.5\times (1-0.5)

n =(19.6)^2 \times 0.5\times (0.5)

n = 96.04

n \approx 96
