Answer:
add up the prices of everything they're buying, divide it by 75 and then multiple the whole answer by 100.
Step-by-step explanation:
X - the original price
3,60 - tax value
5% (= 0,05) - tax rate
-----------------------------------
"<span>Tax value = Original price * tax rate" :
</span>3,60 = x * 0,05
х = 3,60 : 0,05
х = 72 - the original price.
<span>" Original price = tax value ÷ tax rate" :
</span>х = 3,60 : 0,05
х = 72 - the original price.
Form of any quadratic is ax^2 + bx + c
in this equation:
a = 5
b = 6
c = 1
just put in those numbers and you should get the answer
Answer:
0.5
Step-by-step explanation:
From the picture, it is known that 2 is the mean, and it is deduced (by the presence of the dotted lines) that 2.5 is located at the mean plus one standard deviation, and 1.5 is located at the mean minus one standard deviation. Then the standard deviation of the data is 2.5 - 2 = 2 - 1.5 = 0.5
