$\hat{p}=p\pm\frac{\sqrt{p(1-p)}}{\sqrt{n}}\\p=\frac{297}{1873}=0.1586\\ \hat{p}=0.1586\pm\frac{\sqrt{0.1586(1-0.1586)}}{\sqrt{1873}}\\=0.1586\pm\frac{\sqrt{0.1586(0.8414)}}{43.2782}}\\=0.1586\pm\frac{\sqrt{0.1334}}{43.2782}}\\=0.1586\pm\frac{0.3653}{43.2782}}\\=0.1586\pm0.0084$

Which function is best represented by this graph?

Reil [10]

Answer:

y= $\frac{2}{7}$ x-2

Step-by-step explanation:

Slope intercept form is a way to describe a function using its slope and y-intercept and is written as y=mx+b.

m=slope

b=y-intercept

Looking at the graph we can see it goes through x=0 at y=-2 making -2 the y-intercept.

Then we must solve for slope, slope is rise/run. From the point (0,-2) the function travels to (7,0).

This gives us a rise (change in x) of 2 and a run (change in y) of 7 and 2/7 as our slope.

Rina8888 [55]

Answer:

27/18= 1.5

18/6 = 3

3•1.5= 4.5

Step-by-step explanation:

$27 divided by 18 muffins equals $1.50, 18 muffins divided by 6 people equals 3, 3 muffins times $1.50 equals $4.50. So $4.50 is how much each person would have to pay.
