Answer:
17.7 inches.
Step-by-step explanation:
The equation of the line of best fit is y = - 0.368x + 18.483 .......... (1)
Based on the line of best fit, we have to approximate how many inches of snowfall during the month of January when the average temperature is 2°F.
So, here, x = 2 and we have to calculate y using the equation (1).
So, y = - 0.368 × 2 + 18.483 = 17.747 ≈ 17.7 inches. (Answer)
Answer:
5 inches
Step-by-step explanation:
11 inches cost 33 cents
x inches cost 15 cents
Note: we let what we are looking for (inches) be "x"
Now, we can set up two ratios (fractions) and equate them to find the inches we can buy for 15 cents.
The set up:
![\frac{11}{33}=\frac{x}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B33%7D%3D%5Cfrac%7Bx%7D%7B15%7D)
Now we cross multiply and solve for x:
![\frac{11}{33}=\frac{x}{15}\\33x=11*15\\33x=165\\x=\frac{165}{33}\\x=5](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B33%7D%3D%5Cfrac%7Bx%7D%7B15%7D%5C%5C33x%3D11%2A15%5C%5C33x%3D165%5C%5Cx%3D%5Cfrac%7B165%7D%7B33%7D%5C%5Cx%3D5)
Thus, we can buy 5 inches for 15 cents.
For the answer to the question above,
a1 = 40
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>
<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
Answer:
24 3/4
Step-by-step explanation:
multiply 4 1/2 times 1/2 to get your answer..
Number of combinations of 4 men from 5 = 5
number of combinations of 3 women from 6 = 6C3 = 6*5*4 / 3*2*1 = 20
So there are 5*20 = 100 subcommittees possible.
