Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest

lana [24]

Answer:

1/21

Step-by-step explanation:

Cards: 2,3,4,5,6,7,8 7 cards

1st card :5

P(5) = number of 5's / total

= 1/7

Then we keep the card

Cards: 2,3,4,6,7,8 only 6 cards left

card less than 4: 2,3

P (card less than 4) = number of cards less than 4/ total cards

= 2/6 = 1/3

P (5, no replacement, card less than 4) = P(5) * P( less than 4)

= 1/7 * 1/3

=1/21

Point Q is the center of dilation. Lines segment S U is dilated to form line segment S prime U prime. The length of Q S is 3 .2

tia_tia [17]

Answer:

Option C.

Step-by-step explanation:

It is given that the dilation rule is $D_{Q,2.5}$ . It means the center of dilatation is point Q and scale factor is 2.5.

Scale factor is the ratio of distance from center to the image of a point and distance from center to the corresponding point.

$\text{Scale factor}=\dfrac{QU'}{QU}$

It is given that QU=4 and scale factor = 2.5.

$2.5=\dfrac{QU'}{4}$

Multiply both sides by 4.

$2.5\times 4=QU'$

$10=QU'$

We know that

$UU'=QU'-QU$

$UU'=10-4$

$UU'=6$

The distance between U' and U is 6 units.

Therefore, the correct option is C.
