Mrs. Cleaver mixes 1.24 liters of red paint with 3 times as much blue paint to make purple paint. She pours the paint equally in

otez555 [7]

The amount of blue paint in each container is $\fbox{\begin\\\ 0.744 liters \end{minispace}}$ .

Further explanation:

The mixture mixed by Mrs. Cleaver contains 1.24 litres of red paint with 3 times blue paint to obtain purple paint.

So, the amount of blue paint is calculated as,

${3} \times {1.24}=3.72 \text { liters}$

Therefore, the total amount of paint mixture is the sum of blue paint and red paint.

$\fbox{\begin \\\begin{aligned} \text{Total paint}= 1.24+3.72\\=4.96 \text{ liters}\\\end{aligned}\\\end{minispace}}$

Now, as Mrs. Cleaver divides the paint mixture equally in 5 containers so the amount of paint in one container is calculated as,

$\boxed{\begin{aligned}\text{Amount of paint in one container}&= \dfrac{4.96}{5}\\ &=0.992 \text{ liters} \end {aligned}}$

Since amount of blue paint mixed is three times the red paint so the fraction of blue paint to the total paint is $\dfrac{3}{4}$ .

Now, as it is known that the fraction of blue paint to the total paint is $\dfrac{3}{4}$ and the amount of paint in a container is $0.992 \text{ liters}$ then the blue paint in one container is calculated as,

$\boxed{\begin{aligned}\text{Blue paint in one container} =\dfrac{3}{4} \times 0.992\\=0.248 \text{ liters}\end{aligned}}$

Thus, the amount of blue paint in each of the five containers is $\fbox{\begin\\\ 0.744 liters \end{minispace}}$ .

Verify the identity by transforming the left-hand side into the right-hand side.

qaws [65]

(1 + cos² 3θ) / (sin² 3θ) = 2 csc² 3θ - 1

Starting with the left: Note that cos²θ + sin²θ = 1.
In the same way: cos²3θ + sin²3θ = 1
Therefore cos²3θ = 1 - sin²3θ
 From the top: (1 + cos² 3θ) = 1 + 1 - sin²3θ = 2 - sin²3θ

(1 + cos² 3θ) / (sin² 3θ) = (2 - sin²3θ) / (sin² 3θ) = 2/sin² 3θ - sin²3θ/sin²3θ

= 2/sin² 3θ - 1; But 1/sinθ = cscθ, Similarly 1/sin3θ = csc3θ

= 2 *(1/sin3θ)² - 1
= 2csc²3θ - 1. Therefore LHS = RHS. QED.

Select Not independent or Independent for each situation. (3)

valentinak56 [21]

Answer:

A spinner is divided into three equally sized sections. The spinner is spun three times.

independent, since the outcome is not affected by previous spins.

A number cube is rolled twice.

independent, since the outcome is not affected by previous rollings.

A bag contains 8 white balls and 3 yellow balls. Two balls are selected from the bag without replacement.

not independent, since the new outcome depends on the balls that were drawn before.

Step-by-step explanation:

The outcome of an independent variable is not affected by previous outcomes or actions, while the outcome of dependent variables is affected by previous outcomes or actions.
