Hey there!
k - 10/2 = -7
k - 5 = -7
ADD 5 to BOTH SIDES
k - 5 + 5 = -7 + 5
CANCEL out: -5 + 5 because that gives you 0
KEEP: -7 + 5 because it helps solve for the k-value
NEW EQUATION: k = -5 + 7
SIMPLIFY IT & YOU HAVE YOUR ANSWER!
k = -2
Therefore, your answer is: k = -2
Good luck on your assignment and enjoy your day!

9. On a standardized test where the results are distributed normally, Elliete scored a 246. If the mean score was
a 182 with a standard deviation of 36, then what is Elliete's percentile rank (percent less than or equal to 246)
rounded to the nearest whole percent? Explain how you arrived at your answer.
Elliete's percentile rank is 96% for a score less than or equal to 246
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]
Given that μ = 182, σ = 36
For x ≤ 246:
[tex]z=\frac{246-182}{36}=1.78[/tex]
From the normal distribution table:
P(x ≤ 246) = P(z < 1.78) = 0.9625 = 96%
Elliete's percentile rank is 96% for a score less than or equal to 246

Answer the following for 10 points
Answer:
Regional metamorphism
Step-by-step explanation:
(all definitions below are NOT my own definitions, but burrowed from trustworthy informational sites)
It is not Sediment Layering because Sediment Layering is sedimentary rocks layers are piled one on top of the other.
It is not Cooling of Magman because Cooling of Magman is elements within the magma combine and crystalize into minerals that form an igneous rock.
It is not Contact Metamorphism because Contact Metamorphism is metamorphism due to contact with or proximity to an igneous intrusion.
It IS regional metamorphism because it is metamorphism affecting rocks over an extensive area as a result of the large-scale action of heat and pressure.

Jack rode his bike 30 miles 5 hours. At this rate, how long would it take jack to ride one mile?
Answer:
36 seconds
Step-by-step explanation:
30 / (5 x 60) = 0.01
0.01 hours = 0.6 minutes
0.6 minutes = 36 seconds
Answer:
10 minutes
Step-by-step explanation:
First, we need to convert hours to minutes. 5 x 60 = 300.
300 minutes for 30 miles.
Next, divide both numbers by something to equal 1. (Divide it by 30, because we are trying to get 30 to 1.)
300 divided by 30 = 10
30 divided by 30 = 1
So, it would take Jack 10 minutes to ride 1 mile.

Jason and Krystal are selling pecan pies and strawberry cheesecakes for a school fundraiserJason sold 9 pecan pies and 8 strawberry cheesecakes for a total of $153. Krystal sold 2 pecan pies and 6 strawberry cheesecakes for a total of $72. If it is possible to find them, what is the cost of each pecan pie and strawberry cheesecake ? If not possible , explain why
From the equation that was gotten, the value of the pecan pies and the cheesecake will be $9 each.
Based on the information given, the equations to solve the question will be:
9p + 8s = 153 ..... i
2p + 6s = 72 ..... ii
Multiply equation i by 2
Multiply equation ii by 9.
18p + 16s = 306
18p + 54s = 648
Subtract the equations
38s = 342
s = 9
Since 2p + 6s = 72
2p + 6(9) = 72
2p + 54 = 72
2p = 72 - 54.
2p = 18
p = 18/2 = 9
They're both $9 each
