Answer:
57.6% have allergies
42.4% have no allergies
Step-by-step explanation:
We only need to consider the students who speak two languages according to the question.
To find the percent with allergies, divide the number of students with allergies by the total number of students (that speak two languages).
19/33 = 0.5757 = 57.6%
To find the percent without allergies, divide the number of students without allergies by the total number of students (that speak two languages).
14/33 = 0.4242 = 42.4%
Check your work by adding the percentages to make sure they equal 100%
57.6 + 42.4 = 100
Given that y varies inversely with x, then:
y=k/x
where
k is the constant of proportionality:
k=yx
hence, given that x=28 when y=2, then the value of k will be:
k=28×2
k=56
Answer: k=56
2eˣ - 7 = 21
2eˣ = 28
eˣ = 14 How do we isolate for x now? Well we know that aˣ=b can be converted to 
.
x = 
A shorthand for "log base e" is the natural log (ln).
x = ln(14)
x = 2.64 approx.
Exact answer: ln(14)
Approximation: 2.64
Thus, a product that normally costs $300 with a 5 percent discount will cost you $285.00, and you saved $15.00. You can also calculate how much you save by simply moving the period in 5.00 percent two spaces to the left, and then multiply the result by $300 as follows: $300 x . 05 = $15.00 savings.
