Answer:

Step-by-step explanation:

Z = (x-µ)/(s/√n)=(98.5-98.2)/(0.62/√19) = 2.11

left tail p-value = 0.9826

so 98.26% are lower.

Find the equation of the line that contains the points (3,5) and (7, 7). Write the equation in the form y = mx + b and identify
Anastasy [175]

Step-by-step explanation:

Using Point - Slope formula :

(y - y_1) =  \frac{(y_2 - y_1)}{(x_2 - x_1)} (x - x_1)

(y - 5) =  \frac{2}{4} (x - 3)

2y - 10 = x - 3

y =  \frac{1}{2} x +  \frac{7}{2}

m = 1 / 2

b = 7 / 2

46 2/3% of 28 please i need to know answer an work
Bogdan [553]

First, it would help to put 46 and 2/3 into an improper fraction: 140/3.

Then, since this is a percent, we put that improper fraction over 100: (140/3)/100 = 140/300.

Finally, we multiply this answer by 28 since "of" means multiply:

(140/300) * 28 = 196/15 = 13 1/15

What equation is graphed in this figure?
Ksivusya [100]

to get the equation of any straight line, we simply need two points off of it, let's use those two points in the picture below.

(\stackrel{x_1}{0}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{5}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{0}}}\implies \cfrac{3}{1}\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_2=m(x-x_2) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_2}{5}=\stackrel{m}{3}(x-\stackrel{x_2}{1})

keeping in mind that for the point-slope form, either point will do, in this case we used the second one, but the first one would have worked just the same.
