We use the formula d = rt where d = distance, r = rate, t = time
Equation for Sam:
Equation for Sam's father:
d = (12)(t - 0.33)
d = 12t - 4
Since Sam and his father have the same distance from their home to Sam's school, then
2t = 12t - 4
4 = 12t - 2t
4 = 10t
4/10 = t
t = 0.4 hrs or 24 mins
Sam travel 24 mins from home to school and his father travel 4 mins from home to school. Therefore, it was about 8:24 when Sam's father give the project to Sam.
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.

Answer:
Option B
Step-by-step explanation:
Zeros of a function are defined by the values of x at y = 0,
In other words, x-intercepts of a function graph are the zeros of the function.
Real zeros means graph should intersect or touch the x-axis.
If it is imaginary, the graph will have no x-intercept.
From the graph attached,
There are 3 points where the graph intersects the x-axis.
Therefore, the function will have 3 real zeros.
Option B is the answer.
