Answer:
x = 3
Step-by-step explanation:
the midsegment XW is half the sum of the parallel bases , that is
7x + 10 = 
(46 + 16 ) = × 62 = 31 ( subtract 10 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
Answer:
<u>The proportion of the scores that are on the right side of the line is 0.0668</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
µ of a normal distribution = 40
σ of a normal distribution = 10
X = 55
2. What proportion of the scores are on the right side of the line?
Let's calculate the z-score for X = 55, this way:
z-score = (X - µ)/σ
z-score = (55 - 40)/10
z-score = 1.5
Now, using the z-table, let's calculate the proportion, this way:
p (z = 1.5) = 0.9332
In consequence,
p (z > 1.5) = 1 - 0.9332 = 0.0668
It’s 25/6 exact form 4.16 decimal form and 4 1/6 mixed number form
