I-1 is the polynomials because I is the linear term and 1 is the constant
Answer:
3-7 is negitive 4 in your answer it's 3-7 = -4
Step-by-step explanation:
It's negitive four because if you subtract you will get 4 but since it's other way around. And if you do It, it will say that even if there is no negitive sign it won't change the problem because it's still the same problem.
1) 3 - 7
2) there are 3 ways to do this to get the answer:
1) 3/7
2) 7 + 3 - 4 + 3
3) now 7 + 3 is ten - 7 is 3 + 4 is 7, so then if you do 3 - 7 you get negitive four
4) now check your answer by subtracting 3 and 7
5) then you get -4
btw: ( hope this helped :) )
Answer:
You can’t add 3x with 2x because to get term to the other side of the equal sign, you need to do the inverse (opposite) of the number. Since 3x is positive (basically with a + in the front) you SUBTRACT 3x for it to get to the other side. Which will get u -1x or just -x.
If you would like to find the percent markup, you can calculate this using the following steps:
x% of $20 is $29
x% * 20 = 29
x/100 * 20 = 29
x = 29 * 100 / 20
x = 145%
145% - 100% = 45%
The correct result would be 45%.
Answer:
b. Yes, probability is > 0.05
Step-by-step explanation:
We have to find P(X=3) and if the probability is below 0.05 then the it would be unusual and if it isn't below 0.05 we believe that the data from the blood program.
This probability can be found bu binomial distribution with parameters n=6
and p=0.4.
P(X=x)=nCx(p^x)(q^n-x)
where q=1-p=1-0.4=0.6.
P(X=3)=6C3(0.4^3)(0.6^3)
P(X=3)=20(0.064)(0.216)
P(X=3)=0.27648
As the probability that the three have a blood group is greater than 0.05, so, we believe that the data from the blood program.
