Answer:
There is no common difference
Step-by-step explanation:
The ratio is 4:7 because since the ratio is red apples to green apples theirs 4 red apples and theirs 7 green
Using technology, the linear regression equation by fitting the data in the table is ŷ = 2.4x + 11. The predicted number of hits they will be recorded on day 15 is 47.
Using technology such as a regression calculator or excel ;
The regression equation which models the data is ;
- <em>Slope</em><em> </em><em>=</em><em> </em><em>2.4</em><em> </em><em>;</em><em> </em><em>intercept</em><em> </em><em>=</em><em> </em><em>11</em><em> </em>
<u>The</u><u> </u><u>number</u><u> </u><u>of</u><u> </u><u>hits</u><u> </u><u>recorded</u><u> </u><u>on</u><u> </u><u>day</u><u> </u><u>15</u><u> </u><u>:</u>
<u>Substitute x = 15 into the equation</u> :
ŷ = 2.4(15) + 11
ŷ = 47
Therefore, the predicted number of hits on day 15 is 47 hits.

Answer:
p(x) = (x - 5)(x + 5) + 20
Step-by-step explanation:
(x² - 5) ÷ (x - 5) ⇒ we put zero in place of x in the dividend
(x² + 0 - 5) ÷ (x - 5) = x + (5x - 5) ÷ (x - 5)
= (x + 5) + 20 ÷ (x - 5)
The quotient = (x + 5) ⇒ q(x)
The remainder = 20 ⇒ r(x)
The divisor = (x - 5) ⇒ d(x)
∴ p(x) = (x - 5)(x + 5) + 20
