The probability of pulling a blue marble and the coin landing tails up is 360/2500

<h3>How to determine the probability?</h3>

The tables of values are given as:

Color     Times

Blue        18

Green     20

Yellow    12

Heads    Tails

20          30

The probability of obtaining a blue marble is:

P(Blue) = 18/50

The probability of landing tails up is:

P(Tail) = 20/50

The required probability is:

P = P(Blue) * P(Tail)

This gives

P = 18/50 * 20/50

Evaluate the product

P = 360/2500

Hence, the probability of pulling a blue marble and the coin landing tails up is 360/2500

Is -0.75 bigger or less than -0.4?
masya89 [10]

Answer:

Because they are both negative that means they are on the left side so -0.4 is closer to the 0 so less.

12x-24=180 what would x be when you solve this?
miskamm [114]

Hey there!

“12x - 24 = 180”

ADD by 24 on BOTH SIDES

12 - 24 + 24 = 180 + 24

CANCEL out: -24 + 24 because that gives 0

KEEP: 180 + 24 = 204

New equation:

12x = 204

DIVIDE 12 on BOTH SIDES

12x / 12 = 204 / 12

CANCEL out: 12 / 12 because of that gives you 1

KEEP: 204 / 12 because that gives the value “x”

204 / 12 = x

204 / 12 = 17

x = 17 ☑️

Good luck on your assignment and enjoy your day!

Please assist me with this problem
valentina_108 [34]

Answer:

  x = 192

Step-by-step explanation:

The three right triangles in the figure are all similar, so their sides are proportional.

<h3>Proportion</h3>

The length marked x is the long side of the smallest triangle, and the short side of the middle-size triangle. The long side of the middle-size triangle is ...

  400 -144 = 256

We now have enough information to write the proportion ...

  long side/short side = x/144 = 256/x

Multiplying by 144x gives ...

  x² = (144)(256)

  x = √(144×256) = 12×16 = 192

The length x is 192 units.

James says that all numbers have
notka56 [123]

Answer:

No

Step-by-step explanation:

B cause only numbers that have a perfect square are even number of factors.

For example

25 = 5 .1.25

But,

16 = 1 .2.16.8.4

Hence, 16's number of factors is more than 25

Find the slope and y - intercept of the equation Y=3x-2
egoroff_w [7]

Answer:

slope = 3, y- intercept = - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 2 ← is in slope- intercept form

with slope m = 3 and y- intercept c = - 2
