Answer:

Both have the same probabilities of having a meal that includes salmon

Step-by-step explanation:

As they both ordered one main dish, one aske for one of each column, and only in the main dish there´s salmon, and the other one directly asked for one main dish, in the main dish column there´s salmon, so they both have a 1/4 probability of getting salmon.

Your friend says the value of the 7 in the hundredths place of 0.877 is 10 times as great as the 7 in the thousandths

galben [10]

Answer:

Your friend is correct.

Step-by-step explanation:

He is right because 70 is ten times greater then 7 and the question is if the 7 in the hundredths which equals 70, is 10 times greater than the 7 in the thousandths, which is equal to 7. (7 X 10 equals 70.) Hope this helps! :)

Sketch a possible curve of f(x) given the graphs of f ‘ (x) and f’’ (x) below:

Temka [501]

Step-by-step explanation:

Graph 1 is a parabola and has 2 x points and a turning point

meaning it has a minimum and a maximum point.

conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.

Graph 1 is opposite to shown interpreted conclave so instead of --c++

we write + + c - - and draw on quadrant 1 instead of quadrant 3

graph 2 is decreasing so instead of -+ c then + + it would show + - c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.

Both graph 1 and 2 demonstrate minimum points for their f(x) for c.

so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.

Pleasantburg has a population growth model of P(t)=at2+bt+P0 where P0 is the initial population. Suppose that the future populat

Salsk061 [2.6K]

Answer: In June 2097

Step-by-step explanation:

According to the model, to find how many years t should take for $P(t)=21100$ we must solve the equation $0.9t^2+6t+14000=21100$ . Substracting 21100 from both sides, this equation is equivalent to $0.9t^2+6t-7100=0$ .

Using the quadratic formula, the solutions are $t_1= \frac{-6-\sqrt{6^2 -4*0.9*(-7100)}}{2*0.9}=-92.21$ and $t_2=\frac{-6+\sqrt{6^2 -4*0.9*(-7100)}}{2*0.9}=85.54$ . The solution $t_1=-92.21$ can be neglected as the time t is a nonnegative number, therefore $t=t_2=85.54$ .

The value of t is approximately 85 and a half years and the initial time of this model is the January 1, 2012. Adding 85 years to the initial time gives the date January 2097, and finally adding the remaining half year (six months) we conclude that the date is June 2097.
