I WILL GIVE BRAINLIEST

The relative frequency with which the coin will land on tails 12 of those times willl be 48%. None of the given options are correct.

<h3>What is the formula for calculating the joint relative frequency?</h3>

Assume you need to compute the joint relative frequency of a certain category inside a larger category. Then there's the proportion of that specific category's frequency to the total frequency of that large category.

If the experiment is run 25 times and we receive tails 12 times, the relative frequency of receiving tails is as follows:

\rm R = \frac{12}{25} \times 100 \\\\ R = 48 \%

Hence, the relative frequency for the given condition will be 48%.

To learn more about the relative frequency, refer to brainly.com/question/12165221.

Answer in simplest form
solong [7]
Ok, so you know that we can't divide fractions no matter what. The first thing you do is keep the first fraction, then change the divide sign to multiplication ( opposite of division is multi. ) and finallly flip the last fraction to 7/1 . 

Here's a video to help you understand that method more ...

When a person is breathing normally the amount of air in their lawns varies sinusoidally. When full Karen’s lungs hold 2.8 L of
makkiz [27]

Answer:

A(t) = 2.2\sin \frac{(t - 2)\pi }{6} + 0.6

Step-by-step explanation:

Let the function of quantity in the lung of air be A(t)

So A(t) \alpha \sin (\frac{t - \alpha }{k} )

so, A(t) = Amax sin t + b

A(t) = 2.8t⇒ max

A(t) = 0.6t ⇒ min

max value of A(t) occur when sin(t) = 1

and min value of A(t) = 0

So b = 0.6

and A(max) = 2.2

A(t) = 2.2\sin \frac{(t)}{k} + 0.6

at t = 2 sec volume of a is 0.6

So function reduce to

A(t) = 2.2\sin \frac{(t - 2)}{k} + 0.6

and t = 5 max value of volume is represent

so,

\sin \frac{t - \alpha }{k} = 1

\frac{t - 2}{k} = \frac{\pi }{2} when t = 5

\frac{6}{\pi } = k

so the equation becomes

A(t) = 2.2\sin \frac{(t - 2)\pi }{6} + 0.6

-x+ 2y = 10<br> -3x+By = 11
adoni [48]

Answer:

change the equation into one variable.

2 y equals 10 + x

y equals 5 + x by 2

now put that into the second equation

-3x + b parentheses 5 + x / 2 equals 11

-3x+b(5+ x/2)

-3x + b5 + bx/2 = 11
