Marrrta [24]

Answer:

680

Step-by-step explanation:

Use the binomial coefficient where you choose $k=3$ numbers out of $n=17$ possible numbers and find the total amount of combinations since order does not matter:

$\displaystyle \binom{n}{k}=\frac{n!}{k!(n-k)!}\\ \\\binom{17}{3}=\frac{17!}{3!(17-3)!}\\\\\binom{17}{3}=\frac{17!}{3!(14)!}\\\\\binom{17}{3}=\frac{17*16*15}{3*2*1}\\\\\binom{17}{3}=680$

Thus, you can make 680 three-non-repeating-number codes

Miguel wrote the predicted and residual values for a data set using the line of best fit y = 1.82x – 4.3. He left out two of the

Mkey [24]

Answer: a=1.16 and b=0.12

Step-by-step explanation:

We know that the residual value= given - predicted

For x=3

The given value =1.1

The residual value=-0.06

Thus

The predicted value (a)= given- residual

$\Rightarrow\ a=1.1-(-0.06)\\\Rightarrow\ a=1.1+0.06\\\Rightarrow\ a=1.16$

For x=4

The given value =3.1

The predicted value = 2.98

Thus

The residual value (b) = given - predicted

$\Rightarrow\ b=3.1-2.98\\\Rightarrow\ b=0.12$
