Answer:
Step-by-step explanation:
162, 188, 197, 201, 266
a. add all number: 1014/ 5 = 202.8
b. 266-162 = 104
c. for each number subtract the mean and square the result.
1664.64+219.04+33.64+3.24+3994.24
= 5914.8/5 = 591.48
d. square root of variance
= 24.32
e. i don't know this one because i need the number of people in the family
0.5x22=11. To get answers like that, all you have to do is divide 11 by anything and then that number times the number you divided 11 by will give you the answer. So like 11 divided by 4 is 2.75. So 4x2.75=11.
FORMULA:
- Pythagorean property —: h² = b² + p², where h = hypotenuse, b = base, p = perpendicular.
ANSWER:
By pythagorean property,
- x² = 25² + 100²
- x² = 625 + 10000
- x² = 10625
- x = √10625
- x = 103 cm rounded.
Hence, the length of x is 103 cm.
let x be the price before the discount
If you get 12% off, then you only pay the remaining 88% (since 88%+12% = 100%). This means if you take 88% of the original price (x), then you get the final price (132)
In terms of an equation, we have,
88% of (original price) = final price
(88/100)*(x) = 132
0.88*x = 132
0.88*x/0.88 = 132/0.88 <--- divided both sides by 0.88
x = 150

Answer: The price without the discount is $150
