Answer:

0.898

Step-by-step explanation:

The formula for the Coefficient of determination = ratio of explained variation to Total variation

From the above question, we have the following values

Explained variation = 18.592

Total variation = 20.711

The coefficient of determination = 18.592 : 20.711

= 18.592/20.711

= 0.8976872194

Approximately ≈ 0.898

Therefore, the coefficient of determination is 0.898

A store has a sale with 10% off every item. When you enter the store, you receive a coupon that states that you receive an addit
sweet [91]

Step-by-step explanation:

Step one:

We are told that the store offers off 10% of sales, this means that the store is offsetting the price down by 10% hence a price reduction.

Moreso, <em>a coupon is a voucher entitling the holder to a discount off a particular product</em>. the coupon is 40%, hence this is equal to a discount, that is price reduction by 40%.

Step two:

<em>Say the price of an item is $100, a coupon if 40% will entitle the holder to only pay $60, that is</em>

=40/100*100

=0.4*100

=$40 off

= 100-40

=$60

<u>The total percent of reduction 10+40= 50%</u>

<u>This is equal to a discount on the sales price</u>
