What is an equation of the line containing the points (-1,5) and (3,9)​
Lady bird [3.3K]

Answer:

  y = x+6

Step-by-step explanation:

You can find an equation by using the 2-point form of the equation for a line:

  y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

Filling in the given values, we have ...

  y = (9 -5)/(3 -(-1))·(x -(-1)) +5

  y = (4/4)(x +1) +5 . . . . simplifying a bit

  y = x +6

A recent poll of 700 people who work indoors found that 278 smoke. if the researchers want to be 98% confident of their results
Mice21 [21]

Answer:

We are given:

\hat{p}=\frac{278}{700}=0.397

z_{\frac{0.02}{2}}=2.33 is the critical value at 0.02 significance level

E=0.035 is the margin of error

Therefore, the required sample size is:

n=\hat{p}(1-\hat{p}) \left(\frac{z_{\frac{0.02}{2}} }{E} \right )^{2}

      =0.397(1-0.397) \left( \frac{2.33}{0.035} \right)^2

      =0.239391 \times 4431.755102

      =1060.922286 \approx 1061

Therefore, the required sample size n = 1061
