Write an expression that is equivalent to three over four(5z + 16).

1 answer:

8 0

Your answer is B. Using the distributive property, 3/4 • 5z equals 15/4z, which can't be simplified. Then 3/4 of 16 is 12. If you divide 16 by 4 (the denominator) and then multiply by 3 (the numerator) that yields your answer.

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]

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

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

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