Solution :
Original price of a toy( A ) = £50
Increased price = £65
price difference = £65 - £50 =£15
Increased % = ( difference × 100 )/A
= ( 15 × 100 )/50
= 30%

These are chords of a circle, and the equation to solve for any unknowns is to multiply the 2 sections of one chord and set it equal to the mutiplied 2 sections of the other chord. In our case that will look like this: x * 15 = 6 * 5. That's 15x=30. x = 2
Answer:
b,c,e
Step-by-step explanation:
The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>
Using this formula: 
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula would bring the answer as. A. –0.993

Answer:
$9.57
Step-by-step explanation:
You have to do 4.35 divided by 5 to get how much 1 can cost. You will find out that 1 can cost $0.87. Next you will take how much one cost and mutiply it by 11. When you do that you will get 9.57. That is how you will get $9.57 as your answer.
