Ling wants to determine the average distance she travels each day in her car. She records the odometer reading, which measures t

erica [24]

Answer:

$Mean = 10724.29\ mi$

Step-by-step explanation:

Given

$n = 7$ --- days

See attachment for odometer readings

Required

The mean of the distance

Mean is calculated as:

$Mean = \frac{\sum x}{n}$

So, we have:

$Mean = \frac{10150 + 10211 + 10424 + 10769 + 10884 + 11155 + 11477}{7}$

$Mean = \frac{75070}{7}$

$Mean = 10724.2857143$

Approximate

$Mean = 10724.29\ mi$

The perimeter of a rectangle is found by using the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the w

velikii [3]

Answer:

#1: 11 cm

#2: 16.5 in

#3: 2.5 feet

Step-by-step explanation:

$P=2l+2w$ Solve for width by substracting 2l on both sides to isolate 2w

$P-2l=2w$

$2w=P-2l$

Replace.

$2w=26-2(2)\\2w=26-4\\2w=22\\w=\frac{22}{2}\\ w=11cm$

----------------------------------------------------------------------------

$P=2l+2w$

$P=2(3.5)+2(4.75)\\P =7+9.5\\P=16.5in$

----------------------------------------------------------------------------

$P=2l+2w$

Solve for l

$2l=P-2w\\2l=7-2(1)\\2l=7-2\\2l=5\\l=\frac{5}{2}\\ l=2.5feet$
