Answer:

  A.  (5, 9)

Step-by-step explanation:

The first equation tells you x=5, so the only viable choices are A and C.

The second equation tells you ...

  y = 2·5 -1 = 10-1 = 9

so the only viable choice is A.

  (x, y) = (5, 9) . . . . . matches choice A

A set of data has a normal distribution with a mean of 5.1 and standard deviation of 0.9. Find the percent of data between 6.0 a
jolli1 [7]

The percent data between 6.0 and 6.9 would be 13.59%. Here’s the complete solution for this specific problem.

<span>z = (X - Mean)/SD </span><span>
<span>z1 = (6 - 5.1)/09 = + 1 </span>
<span>z2 = (6.9 - 5.1)/09 = + 2 </span>
<span>Required Percent = P(6 < X < 6.9)*100 </span>
<span>= P(1 < z < 2)*100 </span>
<span>= [P(z < 2) - P(z < 1)]*100 </span>
<span>= [0.9772 - 0.8413]*100 </span>
<span>= 0.1359*100 </span>
<span>= 13.59%

I am hoping that this has answered your query.</span></span>

Solve equation? 3(-7+r)=-36
Minchanka [31]
Hey there! 

First we need to add by 21 on each of your sides

Like: 3r - 21 + 21 \\ \\ -36 +21

This gives us: 3r = 15

Now we have to divide by 3 on each sides

Like: \frac{3r}{3}  \\ \\ =  \frac{-15}{3}

Answer: r = -5

Good luck on your assignment and enjoy your day!
