Answer: The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%

Step-by-step explanation:

Given: Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.

The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = $\dfrac{40}{100}\times\dfrac{39}{99}=0.157575757576\approx15.8\%$

Hence, the probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%

If triangle ABC is dilated using a scale factor of 2, what will be the coordinates of A after the transformation

harkovskaia [24]

Answer:

$A' = (-4,4)$

Step-by-step explanation:

Given

$A = (-2,2)$ $B = (1,3)$ $C = (1,0)$

$k =2$ --- scale factor

Required

Determine A'

This is calculated as:

$A' = A * k$

$A' = (-2,2) * 2$

$A' = (-2 * 2,2 * 2)$

$A' = (-4,4)$

<span>3. Two isosceles right triangles

Every square has 4 right angles, so each triangle will have one right triangle, which makes the triangles, right triangles.

They are isosceles because all sides of the square are the same, though the diagonal is not.

Hope this helps :)

Math question down below

frutty [35]

For the first drain the equation you need would be: 2n = 108

for drain B your equation would be: 5n = 108

these are your equations because a number times the amount of water the drain drains per minute will equal 108

to solve use inverse operations and divide 108 by the amount of water the drain drains in one minutes

Drain A- 108/2 = 54
it takes 54 minutes for drain a to empty a pool with 108 gallons of water

Drain B- 108/5 = 21.6
it takes 21.6 minutes for drain b to empty a pool with 108 gallons of water in it<span />
