Using the sinusoidal function, it is found that the temperature will be below 0ºC between May and August.

<h3>What is a Sinusoidal function?</h3>

A sinusoidal function is a function that depends on a trigonometric function, having peaks according to the period and amplitude given by this function.

The function for the average monthly temperature, in m months after January, is given by:

$T(m) = 10\cos{\left(\frac{\pi}{6}\right)m} + 5$

Working with elementary angles, we have that:

$m = 10, T(0) = 10\cos{0} + 5 = 15$

$m = 3, T(3) = 10\cos{\left(\frac{\pi}{2}\right)} + 5 = 5$

$m = 6, T(3) = 10\cos{\pi} + 5 = -5$

$m = 9, T(3) = 10\cos{\left(\frac{3\pi}{2}\right)} + 5 = 5$

$m = 12, T(3) = 10\cos{2\pi} + 5 = 5$

From this, we have that it becomes negative after March, and positive before September, removing the middle two options.

Now, we have to test for April and May, that is, m = 4 and m = 5, hence:

$m = 4, T(4) = 10\cos{\left(\frac{2\pi}{3}\right)} + 5 = 0$

$m = 5, T(5) = 10\cos{\left(\frac{5\pi}{6}\right)} + 5 = -3.66$

Negative only in May, hence the temperature will be below 0ºC between May and August.

Find the median, lower quartile, and upper quartile for the set of data.

harkovskaia [24]

$\text{Find the median:}\\\\\text{To find the median, you would cross out the numbers from the side}\\\text{until you're left with the remainders. Put them in order and solve}\\\\1, 2, 4 ,5, 6, 7, 8, 9, 10, 11\\\text{Add 6 and 7 then divide by 2}\\\\6+7=13\\\\11\div2=6.5\\\\\boxed{\text{The median is 6.5}\\}\\\\\text{The lower quartile is the median of the numbers less than the median, so}\\\text{the numbers from 1-6}\\\\\text{When you cross out the numbers, you would be left with 4}$

$\boxed{\text{The lower quartile is 4}}\\\\\text{Do the same for the upper quartile for the numbers greater than half}\\\text{of the data set}\\\\\boxed{\text{Your upper quartile would be 9}}$

Sydney read 50 pages in 40 minutes. She reads at a constant rate.How many pages can Sydney read per minute?

7nadin3 [17]

Here we are given how much work is done in a fix time interval

then they ask to find the rate of doing the work .

in such problem we can find the rate of doing a work by using the formula :

amount of work done

--------------------------------------------------- = work done in unit time

Time taken to do that amount of work

In 40 minutes number of pages she reads = 50

In 1 minutes number of pages she would be reading = 50 /40

= 5/4 page

Answer 5/4 page .
