|\Omega|=52\\ |A|=\underbrace{40}_{\text{numbered cards}}+\underbrace{13}_{\text{hearts}}-\underbrace{10}_{\text{numbered hearts}}=43\\\\ P(A)=\dfrac{43}{52}\approx83\%

Answer:

d for the first and c for the second

Step-by-step explanation:

1. both are solid lines so it is or equal to something. the first line is going down by -3 and crosses the y axis at -3 so it is _>_ - 3x-3

the second line is going down at -1/2 and crosses the y axis at 2 so it is       _<_ -1/2x+2


2. The point where the two lines cross is at (2.5, -6.5)

For the given function, x can have what value?
Lyrx [107]

Answer:

x cannot be -4,-3, or 13

x can be anything else

Step-by-step explanation:

There are infinitely many values x can take where the relation above will be a function.

For it to be a function, you just need to make sure each x is only assigned one y value.

So x couldn't be -4 because it would by assigned to y=2 and y=0.

x couldn't be -3 because it would be assigned to y=1 and y=0.

x couldn't be 13 because it would be assigned to y=5 and y=0.

So as long as x is not chosen to be -4,-3, or 13 your relation here is a function.

If fan is fully open, what is the approximate area of the fan? Answer choices are attached.
scoundrel [369]

Answer:

Option B. 78.8\ in^2

Step-by-step explanation:

step 1

Find the area of a circle with radius 8.5 inches

The area of a circle is equal to

A=\pi r^{2}

substitute

A=\pi (8.5)^{2}

A=72.25\pi\ in^2

step 2

Find put the approximate area of the fan

we know that

The area of complete circle subtends a central angle of 360 degrees

so

using proportion

Find the area that correspond a central angle of  125 degrees

\frac{72.25\pi}{360^o}=\frac{x}{125^o}\\\\x=72.25\pi(125^o)/360^o\\\\x=25.09\pi\ in^2

assume

\pi =3.14

25.09(3.14)=78.8\ in^2
