Answer: 12/17

Step-by-step explanation:

This is an example of probability with replacement

n(red) = 3

n(green) = 4

n(blue) = 3

n(speckled) = 3

n(yellow) = 4

Total = 17

The probability of getting a green = number of green / total number

That is

p(green) = 4/17

Also

p(red) = 3/17

" and " in probability means multiplication , therefore:

the probability of getting a green and then a red will be

4/17 x 3/17 = 12/17

<h2>It is an obtuse angle.</h2>

Step-by-step explanation:

Obtuse: An obtuse angle is an angle more than $90^\circ$ but less than $180^\circ$ .

Example : $110^\circ$ , $135^\circ$ etc.

Acute : An acute angle is an angle less than $90^\circ$

Example : $30^\circ$ , $45^\circ$ etc.

Straight : A straight angle is $180^\circ$ .

Right: A right angle is $90^\circ$ .

Since the angle is more than $90^\circ$ but less than $180^\circ$ . So, it is an obtuse angle.

A prism is filled with 70 cubes with a side length of 1 2 unit. What is the volume of the prism in cubic units? Enter answer as

galina1969 [7]

Answer:

The volume of the cube is;

$8\dfrac{3}{4} \ cube \, units$

Step-by-step explanation:

The parameters of the prism are;

The number of cubes used to fill the prism, n = 70 cubes

The side length of each cube, s = 1/2 unit

The volume of the cube, V = n × s³

∴ Therefore, the volume of the cube, V = 70 × (1/2)³ = $8\dfrac{3}{4} \ cube \, units$ = 8.75 cube unit

7x-3=-3+7x i neep help answer this please

erica [24]

Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

7x− 3 = − 3 + 7x

Step 1: Simplify both sides of the equation.

7x − 3 = −3 + 7x

7x + −3 = −3 + 7x

7x − 3 = 7x − 3

Step 2: Subtract 7x from both sides.

7x− 3 −7x = 7x −3 −7x

−3 = −3

Step 3: Add 3 to both sides.

−3 + 3 = −3 + 3

0 = 0
