Answer:

Step-by-step explanation:

The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.

So,

$P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\$

Probability of not blue = 1 - Probability of blue

$= 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}$

A right-angled triangle has shorter side lengths exactly c^2-b^2 and 2bc units respectively, where b and c are positive real num

yKpoI14uk [10]

Answer: hypotenuse = $c^{2} + b^{2}$

Step-by-step explanation: Pythagorean theorem states that square of hypotenuse (h) equals the sum of squares of each side ( $s_{1},s_{2}$ ) of the right triangle, .i.e.:

$h^{2} = s_{1}^{2} + s_{2}^{2}$

In this question:

$s_{1}$ = $c^{2}-b^{2}$

$s_{2} =$ 2bc

Substituing and taking square root to find hypotenuse:

$h=\sqrt{(c^{2}-b^{2})^{2}+(2bc)^{2}}$

Calculating:

$h=\sqrt{c^{4}+b^{4}-2b^{2}c^{2}+(4b^{2}c^{2})}$

$h=\sqrt{c^{4}+b^{4}+2b^{2}c^{2}}$

$c^{4}+b^{4}+2b^{2}c^{2}$ = $(c^{2}+b^{2})^{2}$ , then:

$h=\sqrt{(c^{2}+b^{2})^{2}}$

$h=(c^{2}+b^{2})$

Hypotenuse for the right-angled triangle is $h=(c^{2}+b^{2})$ units

A box holds 24 containers of yogurt. Each box has 4 flavors with 6 containers of each flavor. If you choose three yogurts withou

zavuch27 [327]

Answer:

3/6 or 1/2 (50%)

Step-by-step explanation:

There is 6 containers of each flavor, correct?

If you pick 3 of the same flavor, 3/6, it would look like that fraction.

If you simplify it, It'd be 1/2.

If you want it as a percent, It'd be 50%.

As a decimal, It's .50.

13-8+3 evaluate using the Order of Operation

Novay_Z [31]

You would just subtract/add like you normally would from left to right because its a subtract and add operation.

Hope that helps :)

you are working on a project for school. the project will take 12 hours to finish in all. so far, you have worked on the project

nasty-shy [4]

Answer:

6 hours and 45 minutes

Step-by-step explanation:

First, convert 12 hours into minutes.

12*60=720

Convert 5 hours to minutes and add 15

5*60=300+15=315

Subtract 720 from 315.

720-315=405

Convert into hours and minutes.

405/60=6.75

0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
