Answer:
C) -3
Step-by-step explanation:
Rearrange your equation so that it is in slope-intercept form (y = mx + b). The m in the equation is the gradient.
y = 7 - 3x
y = -3x + 7
The m-value is -3. This means that the gradient is -3.
Answer:
3) One-sided,compare two populations
Step-by-step explanation:
A manufacturer wants to investigate the whether there is an increase in the mean gas mileage of mid-sized sedan having new type of tire compared to mean gas mileage of mid-sized sedan not having new type of tire.
So, there are two populations :
population 1 : mid-sized sedan having new type of tire.
population 2 : mid-sized sedan not having new type of tire.
So, two populations are being compared.
Also, A manufacturer is investigating whether there is an increase in mean gas mileage.The alternative hypothesis will be right tailed and so, this corresponds to one sided test.
<span>20 + 30 × 1
= </span><span>20 + 30
= 50</span>
The given points, <span>(0,2) (2,4) (4,6) (6, 8) (8, 10), represent a relationship / function.
The range includes all of the y-values: {2, 4, 6, 8, 10}, which can also be expressed as [2,10]. This is equivalent to answer C.</span>
