Answer:
Range = 205 dollars
Variance = 3255.9 square dollars
Standard deviation = 57.06 dollars
Explanation:
Range = highest price - lowest price = 280 - 75 = 205 dollars
Mean = summation of prices ÷ number of hotels = (186+213+75+188+158+280+197) ÷ 7 = 1297 ÷ 7 = 185.3 dollars
Variance = (summation of square of the difference between each price and mean) ÷ number of hotels = [(186-185.3)^2 + (213-185.3)^2 + (75-185.3)^2 + (188-185.3)^2 + (158-185.3)^2 + (280-185.3)^2 + (197-185.3)^2] ÷ 7 = 22791.43 ÷ 7 = 3255.9 square dollars
Standard deviation = sqrt(variance) = sqrt(3255.9 square dollars) = 57.06 dollars
Answer:
Replacement
Explanation:
Replacement occurs with ions in ionic compounds. Which is shown in this reaction.
Answer:
so he would have to work at least 7 hours
Explanation:
20*12=240
400-240=160
160/24=6.666
The solutions of (93 × p) + 84 = 8593 times p plus 84 equals 85 yields p = 84/8500 or 1/8593.
We can write the equation as follows;
(93 × p) + 84 = (8593 × p) + 84 = 85
We can solve the equation in parts as follows;
(93 × p) + 84 = (8593 × p) + 84
93p + 84 = 8593p
93p - 8593p = -84
-8500p = -84
p = 84/8500
Also;
(8593 × p) + 84 = 85
8593p + 84 = 85
p = 85 - 84/8593
p = 1/8593
Hence p = 84/8500 or 1/8593
