Solve the system of equations x - 2y = – 7 and -3x – 2y = 29 by combining the<br> equations.

Ksivusya [100]

Answer:

x = - 9, y = -1

Step-by-step explanation:

<em>Given:</em>

<em /> $\begin{bmatrix}x-2y=-7\\ -3x-2y=29\end{bmatrix}$

Solve:

$\mathrm{Substitute\:}x=-7+2y$

$\begin{bmatrix}-3\left(-7+2y\right)-2y=29\end{bmatrix}$

$\begin{bmatrix}21-8y=29\end{bmatrix}$

$\mathrm{For\:}x=-7+2y$

$\mathrm{Substitute\:}y=-1$

$x=-7+2\left(-1\right)$

$x=-9$

$\mathrm{Thus, Answer:x=-9,\:y=-1}$

The pool was full with the dump 60 inches the water was drained out at a rate of 8 in./h right the function for this situation

Kobotan [32]

The pool was full with the dump 60 inches the water was drained out at a rate of 8 in./h right the function for this situation

Let

y -----> the number of inches in the water

x -----> the time in hours

we have that

y=60-8x -----> equation taht represent this situation

frez [133]

Answer:

A. fraction 1 and 1 over 2 cubic inches

Step-by-step explanation:

Unit cube side = 1/8 in

<u>Volume of prism:</u>

V= lwh =
16*(1/8)*8*(1/8)*6*(1/8) =
2*1*3/4 =
3/2 = 1 1/2 cubic inches

Candy. Someone hands you a box of a dozen chocolate-covered candies, telling you that half are vanilla creams and the other half

BaLLatris [955]

Answer:

a) P=0.091

b) If there are half of each taste, picking 3 vainilla in a row has a rather improbable chance (9%), but it is still possible that there are 6 of each taste.

c) The probability of picking 4 vainilla in a row, if there are half of each taste, is P=0.030.

This is a very improbable case, so if this happens we would have reasons to think that there are more than half vainilla candies in the box.

Step-by-step explanation:

We can model this problem with the variable x: number of picked vainilla in a row, following a hypergeometric distribution:

$P(x=k)=\dfrac{\binom{K}{k}\cdot \binom{N-K}{n-k}}{\binom{N}{n}}$

being:

N is the population size (12 candies),

K is the number of success states in the population (6 vainilla candies),

n is the number of draws (3 in point a, 4 in point c),

k is the number of observed successes (3 in point a, 4 in point c),

a) We can calculate this as:

$P(x=3)=\dfrac{\binom{6}{3}\cdot \binom{12-6}{3-3}}{\binom{12}{3}}=\dfrac{\binom{6}{3}\cdot \binom{6}{0}}{\binom{12}{3}}=\dfrac{20\cdot 1}{220}=0.091$

b) If there are half of each taste, picking 3 vainilla in a row has a rather improbable chance (9%), but is possible.

c) In the case k=4, we have:

$P(x=3)=\dfrac{\binom{6}{4}\cdot \binom{6}{0}}{\binom{12}{4}}=\dfrac{15\cdot 1}{495}=0.030$

This is a very improbable case, so we would have reasons to think that there are more than half vainilla candies in the box.
