Using the normal distribution, it is found that Sue will get a letter grade of B.
In a <em>normal distribution </em>with mean 
and standard deviation 
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem, Sue got a grade of 0.85, hence 
.
- Looking at the z-table, z = 0.85 has a p-value of 0.8023, hence she is approximately in the top 20%, which is below the top 15% but above the top 50%, hence she got a letter grade of B.

Answer:
See below ~
Step-by-step explanation:
<u>Table 1</u>
⇒ Side length : Perimeter = <u>1 : 4</u>
⇒ Perimeter : Side length = <u>4 : 1</u>
<u></u>
<u>Table 2</u>
⇒ Radius : Diameter = <u>1 : 2</u>
⇒ Diameter : Radius = <u>2 : 1</u>
<u></u>
<u>Table 3</u>
⇒ Number of people : Number of tables = <u>5 : 1</u>
⇒ Number of tables : Number of people = <u>1 : 5</u>

Step-by-step explanation: b) 50 + 50 + 30 + 30 = 160 c) 50 x 30 = 1500
Answer:
x+3y=-1
Step-by-step explanation:
y=3x-2 so m=3 old slope
the new slope must be -1/3 (opposite reciprocal of the old slope).
y-y0=m*(x-x0)
y-2=-1/3*(x-(-7))
y-2=-1/3x-1/3*7
y-2=-1/3x-7/3
3y-6=-x-7
The standard form for linear equations in two variables is Ax+By=C.
x+3y=6-7
x+3y=-1
