First we need the total of both children and adults that like all the flavors:

12 + 5 + 20 + 23 + 11 + 16 = 87 total people

then find the number of adults that like sweet mint: from the table 11 adults like sweet mint

to find the probability divide the number of adults who like sweet mint by the total number of people:

11 / 87 = 0.126
 the answer is A

Answer: I felt so dumb when I realized I was reading it wrong.

The answer is 0.688

The question is asking... out of all the people who liked sweet mint were adults. meaning 5+11=16-> Total    5-> kids 11-Adults  

11/16=0.6875 rounded = 0.688

What compound inequality describes this graph?
katovenus [111]

Answer:

The answer to your question is   0 < x ≤ 3

Step-by-step explanation:

To write this inequality we must consider

- The value of the borders, for this inequality the borders are 0 and 3.

-The kind of border   - if it is an open point, we will use the symbol  <

                                  - if it is a close c point, we will use the symbol ≤

-The inequality for this problem will be

                              0 < x ≤ 3

Write the formula for the parabola that has x- intercepts (3,0) and (8,0), and y- intercept (0,−2)
alexira [117]

Answer:x^2-5x=-12(y+2)

Step-by-step explanation:

Given

Parabola has x-intercept has (3,0) and (8,0)

and Y-intercept as (0,-2)

Now the general equation of parabola is

y=ax^2+bx+c\quad \ldots(i)

Substitute  (0,-2) in (i) we get

-2=c

Now substitute (3,0) in equation (i)

0=a(3)^2+3b-2\quad \ldots(ii)

Now substitute (8,0) in equation (i)

0=a(8)^2+8b-2\quad \ldots(iii)

Solving (ii) and (iii) we get

a=\frac{-1}{12}\ \text{and}\ b=\frac{5}{12}

therefore

y=\frac{-x^2}{12}+\frac{5x}{12}-2

12y=-x^2+5x-24

A population of rabbits is described by the function R(t) = 100(2t/5), where t is measured in months and R is measured in rabbit
Savatey [412]

Answer and Step-by-step explanation: The graph is shown in the attachment.

a. ΔR on [1,2] is mathematically expressed as:

ΔR = R(2) - R(1)

which means difference of population of rabbits after 2 months and after 1 month.

R(1) = 100(\frac{2}{5}.1 )

R(1) = 100(\frac{2}{5} )

R(2) = 100(\frac{2}{5}.2 )

R(2) = 100(\frac{4}{5} )

\Delta R = 100(\frac{4}{5} )-100(\frac{2}{5} )

\Delta R = 100[\frac{4}{5} - \frac{2}{5} ]

\Delta R= 40

Difference of rabbits between first and second months is 40.

b. R(0) = 100(\frac{2}{5} .0)

R(0) = 0

Initially, there no rabbits in the population.

c. R(10) = 100(\frac{2}{5}.10 )

R(10) = 400

In 10 months, there will be 400 rabbits.

d. R(t) = 500

500=100(\frac{2}{5}.t )

\frac{500}{100}=\frac{2}{5}.t

t = \frac{500.5}{100.2}

t = 12.5

In 12 and half months, population of rabbits will be 500.
