Answer:

133.5, 127.5, 139.5, 12

Step-by-step explanation:

order data:

106, 127, 129, 132, 135, 138, 140, 158

Median:

The middle number: (8+1)/2 = 4.5 between the 4&5 numbers

= (135-132)/2= 1.5

1.5 + 132 = 133.5

lower quartile (1st quartile):

(8+1)/4 = 2.25 between the 2&3 numbers

(129+127)/4=0.5

0.5+127 = 127.5

upper quartile(3rd quartile):

(8+1)/4 x3 = 6.75 between the 6&7 numbers

(140-138)/4 x3 = 1.5

1.5 + 138 =139.5

Interquartile range:

139.5-127.5= 12

hope this helps

.Shaun estimated that the attendance at a college
Serggg [28]

Answer:

38.72%

Step-by-step explanation:

Estimated attendance = 1,000

The actual value of attendance = 1,632

We need to find the percent error of Shaun's estimate. Using the formula as follows :

\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100

Put all the values,

\%=\dfrac{1632-1000}{1632}\times 100\\\\=38.72\%

So, the percent error of Shaun's estimate is 38.72%.

gregori [183]
<span>Each ticket costs $10. He bought "x" tickets. Ticket cost = 10*x
Each bag of popcorn costs $5.
He bought "y" bags of popcorn.
Popcorn cost = 5*y Service fee: $3
Total cost = 10x + 5y + 3 <= $75 is the inequality.
10x + 5y <= 72
If x = 4,
then 40 + 5y <= 72
5y <= 32
y <= 6.4
So y = 6 bags of popcorn.</span>
