There are 22 roses in the vase 
probability of first selecting a red rose = 8/22 = 4/11

P( second one is red) = 7/21 = 1/3

these probabilities are multiplied because the individual picks are independent
 so the answer is 4/11 * 1/4  = 4/33

iren2701 [21]
When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!

If PG' equals 0. 5 units, what is PG? 2. 5 units 3 units 4. 5 units 6 units.
Dmitrij [34]

The correct option is B which is the value of PG is 3 units.

Given

The scale factor of the dilation of segment HG is 1/6.

If PG' equals 0.5 units,

<h3>What is the scale factor?</h3>

The scale factor is a measure for the identical shapes, which look identical but have various scales or measures.

The scale factor of the dilation of segment HG is 1/6.

By the rule of scale factor;

\rm \dfrac{PG'}{PG}= SF = \dfrac{1}{6}

Where SF represents the scale factor.

Solving for PG, we get:

\rm \dfrac{PG'}{PG}=\dfrac{1}{6}   \\\\ \dfrac{0.5}{PG} = \dfrac{1}{6}\\\\ 0.5 \times 6= 1\times PG\\\\ PG = 3

Hence, the value of PG is 3 units.
