Which is the equation of the line with slope 3 that contains point (-1, 5)?

sattari [20]

$\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{5})~\hspace{10em} slope = m\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-5=3[x-(-1)] \\\\\\ y-5=3(x+1)\implies y-5=3x+3\implies y=3x+8$

Isaac, a manager at a supermarket, is inspecting cans of pasta to make sure that the cans are neither dented nor have other defe

Fynjy0 [20]

Answer:

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.

Step-by-step explanation:

W are given the following in the question:

Probability of defective can =

$P(A) = \dfrac{1}{90}$

We have to find the probability that Isaac will find his first defective can among the first 50 cans.

Then the number of adults follows a geometric distribution, where the probability of success on each trial is p, then the probability that the kth trial (out of k trials) is the first success is

$P(X=k) = (1-p)^{k-1}p$

We have to evaluate:

$P(x = 50)\\= (1-\frac{1}{90})^{50-1}(\frac{1}{90})\\= 0.0064$

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.

Answer:

x+y=37-------(1)

5.5x+13.5y=355.5-----(2)

Put x=37-y in eqn 2

5.5(37-y)+13.5y=355.5

203.5-5.5y+13.5y=355.5

8y=152

y=19

x=18
