Answer:
55%
If 1,210 people would buy that type of car again, they were satisfied with it.
The fraction of people who were satisfied would be
.
To find a percentage, we need to divide the top of the fraction by the bottom, then multiply by 100.
1210/2200 is equal to 0.55. This is the decimal form of the fraction, but we need the percentage.
0.55 x 100 is equal to 55.
The answer is 55%
The first one is < the second one is < and the last one is =
Answer:
The first one: {{7, 12), (1, -5), (3, -10), (2, -5)}
Step-by-step explanation:
Functions can't have repeating x values. Each x has to have its own y value.
Answer:


So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
Step-by-step explanation:
Let X the random variable that represent the number of rookie cards of a population, and for this case we know the distribution for X is given by:
Where
and
We select a sample size of n = 10 variety packs and we want to find this probability:
We can use the z score formula given by:
If we apply this formula to our probability we got this:
We can find the z score for 2 and 4 and we got:


So we can find the probability with this difference
And using the normal standard distirbution or excel we got:
So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
Answer:
x=17/11
Step-by-step explanation:
1. 7−3(x−4)=2(4x+1)
2. −3x+19=8x+2
3. −3x+19−8x=8x+2−8x
4.−11x+19=2
5. −11x+19−19=2−19
6.x=(17/11)
Hope this helps :)
