6. 7×(x+2)=56

x+2=56/7

x=8-2

x=6

7. 12÷(x-2)=3

x-2=3×12

x-2=36

x=38

8. (7+5)×x=36

12×x=36

x=36÷12

x=3

9. (7-5)×x+3=7

(7-5)×x=7-3

2×x=4

x=4÷2

x=2

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]

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

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

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

Express it in slope-intercept form.

e-lub [12.9K]

Answer:

y = 1/2x -1

The slope is increasing by 2/4, which can be reduced to 1/2. You can find this by doing rise over run.

The y intercept is -1
