Answer 1
Answer: Mean = $65.85
S.D. = $36
For 1 s.d.: 65.85 - 36 ≤ x ≤65.85 + 36 => 29.85 ≤ x ≤ 101.85
But $25.60 and $126.40 does not fall within 1 standard deviation.
Therefore, all the prices fall within 2 standard deviations.

Mean = (146 + 189 + 246 + 178 + 203)/5 = 192.4
S.D. = sqrt[(146 - 192.4)^2 + (189 - 192.4)^2 + (246 - 192.4)^2 + (178 - 192.4)^2 + (203 - 192.4)^2] = 73.2
For 1 S.D.: 192.4 - 73.2 ≤ x ≤ 192.4 + 73.2 => 119.2 ≤ x ≤ 265.6
All the weight falls within 1 standard deviation of the mean.

P= a+b+2c solve for c

Answers

                    P = a + b + 2c
          P - a - b = a - a + b - b + 2c
          P - a - b = 2c

Factorize (4y-5)²+80y ​

Answers

Answer:

16y^2+40y+25

Step-by-step explanation:

{16y}^(2) + 40y + 25

Step-by-step explanation:

(4y−5)^2+80y

Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.

16y^2−40y+25+80y

Combine −40y and 80y to get 40y.

16y^2+40y+25

A square is inscribed in a circle of radius 3 square root 2 find the area

Answers

inscribed means drawn inside with corners touching sides of circle

we know that r=3√2
if we double that we get the diameter of 6√2
this also is the diagonal of the square

we now have pythagoran theorem
the 2 legs are equal measure since it is a square
hypotonuse=diangoal of square

a^2+b^2=c^2
a=b
2a^2=c^2
2a^2=(6√2)^2
2a^2=72
divide both sides by 2
a^2=36
sqrt both sides
a=6
the legnth of one side is 6

area=side^2
area=6^2
area=36 

the area is 36 square units
