What is the slope and y-intercept of the line y=1/3x-7
Juli2301 [7.4K]

Answer:

1/3, -7

Step-by-step explanation:

Before answering this, I will need to assume that you actually meant

y = (1/3)x - 7.  Comparing this to y = mx + b, we see that the slope, m, is 1/3 and the y-intercept, b, is -7.

A certain process for removing copper from copper bearing ore had been in use for a period of time, and it is known that this pr
Anika [276]

Answer:

d. Ore treated with the new process.

Step-by-step explanation:

This is a common practice in statistics, in which we use a sample of a population to infer something about the entire population. We should use a sample of 100.

For example, if we want to know the proportion of residents of Buffalo, New York, who are Bills fans, we are going to take a sample of like, 100 residents, and then use this to estimate for the entire city.

In this problem, we have that:

A new process that is supposed to increase the recovered amount is being tested. In a simple random sample of 100 batches of ore, an average of 42 pounds per ton were recovered using the new process.

So the population of interest is the ore treated with new process. We use a sample of 100 to gather information about the entire population.

So the correct answer is:

d. Ore treated with the new process.

Answer:

Step-by-step explanation:

a). Total surface area of cylinder is defined by sum of curved surface area and surface area of the top and bottom.

Total surface area = 2πrh + 2πr²

Skateboarders use a half pipe structure which are not closed at the ends.

Therefore, curved surface of the half pipe = \frac{2\pi rh}{2}

                                                                      = πrh

b). If r = 2.5 m and h = 9 m,

Curved surface area of the half pipe = π(2.5)(9)

                                                             = 70.69 m²

                                                              ≈ 71 m²

tatiyna
Height over shadow
H/S

9 in is 9/12=.75
So
Boys height /shadow. Flags height /shadow

4.75/6= X/19




Cross multiply
6x= 90.25
Divide by 6
X= 15.0
