Number 6 is A the slope of the graph is -1 and the starting point is seven, so that means your equation is y = -1x +7, it can also be written as y=-x+7

Number 7 is C if I’m not mistaken, because as the absent goes up the dots for grade point average goes down

Number 8 is A, because as more missing assignments goes up your grade will go down meaning it will be negative

Answer:

Margin of error $=E=[69]$

Step-by-step explanation:

Data provided in the question:

$\bar{x}=\$\ 893$

$\sigma=\$\ 450$

$n=102$

At $88 \%$ confidence level the $z$ is.

$\alpha=1-88 \%=1-0.88=0.12$

$\frac{\alpha}{2}=\frac{0.12}{2}=0.06$

$z_{\frac \alpha 2}=20.06=1.555$

$\text { Margin of error }=E=Z_{\frac \alpha 2} \times \frac{\sigma}{\sqrt{n}}$

$E=1.555 \times \frac{450}{\sqrt{102}}$

Margin of error $=E=[69]$

Question 2 Determine if (x-3) is a factor to the polynomial P(x) = 2x³ +5x²-28x - 15. (3 marks)

tangare [24]

Answer:

(x - 3) is a factor of P(x)

Step-by-step explanation:

if (x - 3) is a factor of P(x) then P(3) = 0

P(3) = 2(3)³ + 5(3)² - 28(3) - 15

= 2(27) + 5(9) - 84 - 15

= 54 + 45 - 99

= 99 - 99

= 0

since P(3) = 0 then (x - 3) is a factor of P(x)
