Answer:
hey guys whats up!
i think your answer is
1. you can spin the spinner a certain way and it is more likely to land on the answer you want or if it has anything to do with colors then make the color you want to take up more space.
2.you can as the other question above states do the opposite.
3.to make an event impossible you can do this:if it is a color leave it out,this means that it will not land on it so it is impossible.
4.to make an event certain you can do the opposite of answer 3

Answer:
Step-by-step explanation:
Hello!
The variable of interest in this case is:
X: length of time before a major repair is required on a new car. (months)
This variable has a normal distribution with mean μ= 36 months and a standard deviation σ= 9 months.
If he wants to set a guarantee period in which only 5% of the sold cars fell, the objective is to find the value of X that has below 5% of the cars that need major repairs before the end of the guarantee period.
Check the attachment, the curve represents the distribution of the population of the time it takes before a new car needs major repairs, I've marked approximately where this value of X should be.
Symbolically:
P(X≤a)=0.05
To reach the proper value of "a" you have to work using the standard normal distribution because is a tabulated distribution and you can extrapolate it to any normal distribution.
So the first step is to look in the table of the Z distribution for the value that accumulates 0.05 of probability since it is such a low probability, you have to look for the value in the left side of the table (negative values of Z). You look for 0.05 in the body of the table and then the margins for the corresponding value (see second attachment)
Then the value that accumulates 0.05 of probability is -1.64, now you have to reverse the standardization to reach the asked value of X
Z= (a- μ)/σ
(Z*σ)= a - μ
a=(Z*σ)+ μ
a=(-1.64*9)+36
a= 21.24 months.
The guarantee period should be 21.24 months so that only 5% of the sold cars will need major repairs before it wears of.
I hope it helps!
You need to multiply 2.25 by 80 and it will equal 180 so the answer is....you need to sell 80 keychains. Hope i helped :-)
Answer:
28.21 = 4x + 4.61
Step-by-step explanation:
Since x equals the bags of apples and he bought 4 of them, we would multiply x by 4 like this: 4x
$4.61 were already added to the total cost of $28.21
If we wanted to find out how much each bag cost, we subtract 4.61 from both sides
28.21 = 4x + 4.61
- 4.61. - 4.61
23.6 = 4x
Then, divide both sides by 4
23.6/4 = 4x/4
x = 5.9
Each bag of apples cost $5.90
Answer:
the answer is c because ef was dialted by 0.5 causing it to be divided by 2 if it make any sense.
