Please help with this question.<br>

Answer:

27.27%

Step-by-step explanation:

Given that,

Initial price = 11

Final price = 8

We need to find the percentage change in the price. It can be calculated as follows :

% = [(final-initial)/initial] × 100

So,

$\%=\dfrac{11-8}{11}\times 100\\\\\%=27.27\%$

So, the percentage decrease is 27.27%.

Answer:

measure of major arc BEA = 224.4° Option D

Step-by-step explanation:

Given that, measure of inscribed angle ∠BEA = 67.8°

Firstly we will find the central angle.

Suppose O is the center of given circle

So, ∠AOB = 2∠AEB

∠AOB = 135.6°

The measure of arc AB is same as the measure of its central angle.

So, measure of AB arc = 135.6°

Now complete circle measure = 360

Measure of major arc AEB = 360° - measure of arc AB

= 360° -135.6°

= 224.4°

That's the final answer.

Below are the results of tossing a number cube 9 times. Find the experimental probability of tossing an odd number. 4, 3, 6, 6,

My name is Ann [436]

Answer: C. $\dfrac{5}{9}$

Step-by-step explanation:

Given: The results of tossing a number cube 9 times are:

4, 3, 6, 6, 2, 5, 3, 5, 1

Then , the number of times get odd number (3,5,3,5,1): 5

Now, the experimental probability of tossing an odd number will be :

$\text{P(odd)}=\dfrac{\text{Number odd results}}{\text{Total number of times coin tossed}}\\\\\Rightarrow\ \text{P(odd)}=\dfrac{5}{9}$

Hence, the experimental probability of tossing an odd number $\dfrac{5}{9}$
