The slope is 8.5

Take any 2 points and apply the slope equation. You will get the same slope.

The constant proportionality is the same as the slope.

Hope it helps :)

A new surgery is successful 75% of the time. if the results of 10 such surgeries are randomly sampled, what is the probability t

valentinak56 [21]

$\text{Binomial Distribution: } P(X = r) = \binom{n}{r}(p)^{r}(1 - p)^{n - r}$
$P(X < 9) = 1 - P(X = 9) - P(x = 10)$

$P(X = 9) = \binom{10}{9}(0.75)^{9}(0.25)$
$P(X = 10) = \binom{10}{10}(0.75)^{10}$

$P(X < 9) = 1 - \binom{10}{9}(0.75)^{9}(0.25) - \binom{10}{10}(0.75)^{10}$
$\approx 0.755974769...$

Solve the inequality. Graph the solution set.<br><br> 2r−9≤−6

Ahat [919]

We have that

2r−9≤−6------> 2r ≤ -6+9-------> 2r ≤ 3-----> r ≤ 1.5

the solution is the interval (-∞, 1.5]

using a graph tool
see the attached figure
