The Candy Store held a raffle, and Matt won the grand prize. He won a gift card to the store, as well as a bag of giant lollipop

s. He gave 21 lollipops to his friends, and he kept the remaining 7 lollipops. Which equation can be solved for n to find the total number of lollipops in the bag?

Answer:

<h2>28 lollipops.</h2>

Step-by-step explanation:

Let's say that $n$ is the total number of lollipops in the bag, which Matt won.

So, if Matt gave 21 lollipops to his friends, and he kept with 7 lollipops, that means there were 28 lollipops in the bag.

If we represent this as an equation, would be:

$n=F+M$

Where $F$ is friend's lollipops, and $M$ is Matt's lollipops.

Replacing values we have:

$n=21+7=28$

Therefore, in the bag were 28 lollipops in total.

21 (friends) + 7 (himself) = n
To solve this, n = 28.
There were 28 lollipops in the bag.

Determine whether the given differential equation is exact. If it is exact, solve it. (If it is not exact, enter NOT.) (tan(x) −

never [62]

Answer:

$f(x,y)=ln secx+cosx siny+C$

Step-by-step explanation:

We are given that DE

$(tanx-sinx siny)dx+cosxcosydy=0$

We have to determine given DE is exact or not.

Compare it with Mdx+Ndy=0

$M=tanx-sinx siny$

$N=cosxcosy$

$\frac{\partial M}{\partial y}=$ $M_y=-sinxcosy$

$\frac{\partial N}{\partial x}=N_x=-sinxcosy$

Therefore, $M_y=N_x$

If DE is exact then $M_y=N_x$

Hence,it is exact.

$M=\frac{\partial f}{\partial x}=tanx-sinxsiny$

Integrate w.r.t x on both sides

$f(x,y)=\int(tanx-sinxsiny)dx$

$f(x,y)=lnsecx+cosxsiny+\phi(y)$ ...(1)

By using the formula

$\int tanxdx=lnsecx+C,\int sinxdx=-cosx+C$

Differentiate partially equation (1) w.r.t y

$\frac{\partial f}{\partial y}=cosxcosy+\phi'(y)$

By using the formula:

$\frac{d(sinx)}{dx}=cosx$

$N=\frac{\partial f}{\partial y}=cosxcosy=cosxcosy+\phi'(y)$

$\phi'(y)=cosxcosy-cosxcosy=0$

$\phi'(y)=0$

Integrate w.r.t y

$\phi(y)=C$

Substitute the value

$f(x,y)=ln secx+cosx siny+C$

Which statement about the data is true

Alina [70]

Answer:

D. A value of 0.9 is more than 2 standard deviations from the mean.

Step-by-step explanation:

A is wrong, because the standard deviation is +/-0.15 (the measure up or down from the mean)

B is wrong, because the mean is exactly 0.5

C is wrong, because 1 standard deviation up from the mean is 0.65, and 0.7 is outside of that.
