The equation would be y = -1/3x -6
Answer: y=40x+100
Step-by-step explanation: it’s growing by 40 every week so x=number of weeks and 100 is the starting point so you always add that. Ex) week 3: 40(3)+100 = 120+100=220
Answer:
26
Step-by-step explanation:
When you flip two coins, you can have 4 different outcomes:
HH
HT
TH
TT
All outcomes are equally likely, but notice that if you do not keep track of which coin is which, you will get 1/4 of the flips to be both heads, 1/4 of the flips to be both tails, and 1/2 of the flips to be one heads and one tails.
p(both heads) = 1/4
With 105 flips, the expected number of both heads is
105 * 1/4 = 26.25
Answer: 26
Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
