If x + 3y = 7 and x - 3y =7 , then find y<br><br> Please help me
telo118 [61]

Answer:

x + 3y = 7 , x - 3y = 7 : y = , x = 7

Step-by-step explanation:

\left[\begin{array}{ccc}x + 3y = 7\\x - 3y = 7\end{array}\right]

Isolate x for x + 3y = 7 : x = 7 - 3y:

Substitute x = 7 - 3y:

\begin{bmatrix}7-3y-3y=7\end{bmatrix}

Isolate y for 7 - 3y - 3y = 7 : y = 0:

For x =7-3y

Substitute y = 0

x=7-3 * 0

7 - 3 * 0 = 7

x = 7

The solution to the system of equations are:

y=0,\:x=7

Hope I helped. If so, may I get brainliest and a thanks?

Thank you. Have a good day! =)

One variable examined is the survival rate 10 years after tagging. The scientists observed that 10 of the 50 metal tagged pengui
Oksana_A [137]

Answer:  90% confidence interval would be (-0.2483,-0.0717)

Step-by-step explanation:

Since we have given that

n₁ = 50

Number of metal tagged penguins survived = 10

So, p_m=\dfrac{10}{50}=0.2

n₂ = 50

Number of electronic tagged penguins = 18

So, p_e=\dfrac{18}{50}=0.36

So, at 90% confidence interval, z = 1.28

So, interval would be

(p_m-p_e)\pm z\sqrt{\dfrac{p_m(1-p_m)}{n}+\dfrac{p_e(1-p_e)}{n}}\\\\=(0.2-0.36)\pm 1.28\sqrt{\dfrac{0.2\times 0.8}{50}+\dfrac{0.36\times 0.64}{50}}\\\\=-0.16\pm 0.0883\\\\=(-0.16-0.0883,-0.16+0.0883)\\\\=(-0.2483,-0.0717)

Hence, 90% confidence interval would be

(-0.2483,-0.0717)
