Step-by-step explanation:

1)......mean= sum of observations/ total observations

= 5.2+8.4+4.3+6.7+5.8/5= 6.08

median= n=5(odd)=n+1/2=6/2=3rdterm= 5.8( when arranged in ascending order).....

mode= 3median- 2meam= 3×5.8-2×6.08= 5.24

range=8.4-4.3=4.1(when done A.O)

2)......mean= -2-13-13-5-7/5= -8

median= 3rd term= -5.....(n=5..odd)(when done A.o)

mode=largest frequency= -13

range= -13-(-2) = -13+2= -11(A.O)

3).....mean= sum/no.= 8+6+13/2+17/2+15/2+7+8+11/2+7+8//10=7.2

median=n=10(even)

=

mode= 8

range=8.5-5.5=3

median:==

(10/2)+(10/2+1)//2=5 term + 6term/2=7+7.5=14.5/2=7.25

4)....

5)...remove 62...then 73will be having highest frequency

Miriam has 62 feet of fencing to make a rectangular vegetable garden. Which dimensions will give Miriam the garden with greatest
lidiya [134]
Perimeter: P=62 feet
P=2(b+h)
62=2(b+h)
Dividing both sides of the equation by 2:
62/2=2(b+h)/2
31=b+h
b+h=31   (1)

Area: A=bh   (2)

Isolating h in equation (1)
(1) b+h=31→b+h-b=31-b→h=31-b   (3)

Replacing h by 31-b in equation (2)
(2) A=bh
A=b(31-b)
A=31b-b^2

To maximize the area:
A'=0

A'=(A)'=(31b-b^2)'=(31b)'-(b^2)'=31-2b^(2-1)→A'=31-2b

A'=0→31-2b=0
Solving for b:
31-2b+2b=0+2b
31=2b
Dividing both sides by 2:
31/2=2b/2
31/2=b
b=31/2=15.5

Replacing b by 31/2 in equation (3)
h=31-b
h=31-31/2
h=(2*31-31)/2
h=(62-31)/2
h=31/2

The dimensions are 31/2 ft x 31/2 ft = 15.5 ft x 15.5 ft
The area with these dimensions is: A=(15.5 ft)(15.5 ft)→A=240.25 ft^2

These dimensions are not in the options

1) The first option has an area of: A=(18 ft)(13 ft)→A=234 ft^2
2) The second option has an area of: A=(19 ft)(12 ft)→A=228 ft^2
3) The third option has an area of: A=(17 ft)(14 ft)→A=238 ft^2

The third option has the largest area.

Answer: Third option

Is 5.78778777 a rational or irrational number?..
kupik [55]

That number is the ratio of 578,778,777 to 100,000,000 , so it's rational.

Here's a surprising factoid:

ANY number that you can completely write down on paper with digits...
and a decimal point or a fraction bar if you need them ... is rational.

If you can write it down ... without saying "repeating" or using symbols ...
it's rational.
