Yes because all of x are different numbers.
Answer: The required equation is,
Step-by-step explanation:
Let x be the size of the larger bottle,
Since, the size of smaller bottle of lotion = 5.4 ounces,
According to the question,
The larger bottle gives 20% more free lotion,
The size of the larger bottle = The size of smaller bottle of lotion + 20 % of the size of smaller bottle of lotion
= 120 % of the size of smaller bottle of lotion
= 120 % of 5.4
Which is the required equation that could be used to find the size of the larger bottle.
Answer:
3x² - 21x + 30
Step-by-step explanation:
y = 3(x - 5)(x - 2) ← expand factors using FOIL
= 3(x² - 7x + 10) ← distribute parenthesis by 3
y = 3x² - 21x + 30 ← in standard form
Step-by-step explanation:
Samuel's sons age=16p/4
24 =4p
p=6
Samuel's age =16×6
=96 years old
Answer:
a) We can be 95% sure that true average age (in weeks) at which babies begin to crawl is between 30.65 weeks and 32.89 weeks.
b) Margin of error for the confidence interval is 1.12 weeks.
Step-by-step explanation:
Let m be the estimate of the average age (in weeks) at which babies begin to crawl
Let ME be the margin of error.
- Lower bound of the confidence interval is m-ME (32.89 weeks)
- Upper bound of the confidence interval is m+ME (30.65 weeks)
then the <em>difference</em> between the upper bound and the lower bound gives:
m+ME - (m-ME) = 2ME = 32.89-30.65=2.24 which gives
ME=1.12 weeks
