Answer:
Marissa = 28 cakes in 2 weeks
Carlos = 60 cakes in 20 days
Shelby = 5 cakes in 2 days
To compare, make sure that the variables are of equal value
Marissa = 28 cakes in 14 days
Carlos = 60 cakes in 20 days
Shelby = 5 cakes in 2 days
How many cakes does each of them bake in a day?
Marissa = 28 ÷ 14
= 2 cakes/day
Carlos = 60 ÷ 20
= 3 cakes/day
Shelby = 5 ÷ 2
= 2.5 cakes/day
Carlos has the steepest graph. This is because he has the largest number of cakes made per day compared to Marissa and Shelby.
Answer:
The confidence interval for the mean is given by the following formula:
Step-by-step explanation:
1) Notation and definitions
number of people or things with a specific characteristic.
random sample taken
estimated proportion of people or things with a specific characteristic.
true population proportion of people or things with a specific characteristic.
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
The population proportion have the following distribution
If we have all the conditions required in order to construct the confidence interval:
1) Random sample selected
2) np >10
3) n(1-p)>10
Then the confidence interval for the mean is given by the following formula:

Answer: A. , its a polynomial fraction
Step-by-step explanation:
monomial - one term
<em>ex: -2x^5</em>
binomial - two terms
<em>ex: x^2+5</em>
trinomial - three terms
<em>ex: 3x-8+4x^5</em>
polynomial - four terms
<em>ex: -7a^2 + 9b - 4b^3 + 6</em>
