Answer:

No, she's wrong

x\leq\frac{2}{5}

Step-by-step explanation:

So starting from the beginning...

3x+3\leq -2x+5

Subtract the 3 from both side and it will look like...

3x\leq-2x+2

Then add 2x from both sides and it will look like...

5x\leq 2

Finally divide by 5 to both sides and it will look like...

x\leq \frac{2}{5}

VLD [36.1K]

The answer is 95.4525 percent because you would use an equation

n!/(r!(n-r)! x (P)^x * (1-P)^(n-x)

Plug in the number correspondingly

N= 10

R= 1 , 2 , 3 , 4 , 5 , 6 (You will have to do each individual, if you have a Ti-nspire calculator however there is a built program called binomialcdf.

P= .37

x = r

After plugging this is the achieved answer is 95.4525

(.0578 + .1529 + .2394 + .2461 + .1734 + .0849) x 100

additive may be a little off due to rounding.

Can someone help me with this?
jekas [21]

Answer:

\huge\purple{ x^2 +(y+2)^2 = 4}

Step-by-step explanation:

Circle is centred at (0, -2)

-> h = 0 & k = - 2

radius of the circle (r) = y-coordinate of the center = - 2

Equation of circle in standard form is given as:

(x-h)^2 +(y-k)^2 = r^2

Plugging the values of h, k and r in the above equation, we find:

(x-0)^2 +[y-(-2)]^2 = (-2)^2

\implies\huge\orange{ x^2 +(y+2)^2 = 4}

This is the required equation of circle.
