9 miles per hour is the answer

His average speed per hour is 9 mph since he is able to row 4.5 miles in a half hour, doubling that number would give you his speed per hour.

The function f(x) = x2. The graph of g(x) is f(x) translated to the left 6 units and down 5 units. What is the function rule for
Y_Kistochka [10]

Answer:

g(x) = (x + 6)^2 - 5

Step-by-step explanation:

To translate f(x) to the left by 6 units, replace x with x+6.

To translate f(x) down 5 units, replace f(x) with f(x)-5.

Together, these replacements give you ...

... g(x) = f(x+6) -5

... g(x) = (x +6)^2 -5

How much lighter is 345 g than 1,1 kg​
NemiM [27]

Answer:

755 gram lighter

Step-by-step explanation:

Convert 1.1kg into gram by multiplying it with 1000

1.1 x 1000= 1100 and we take this amount and subtract it with 345g

1100-345= 755g

Students from two age groups were surveyed to see how they travel to school. Here are the results:
liq [111]

Answer:

The table representing the number of students by which mode of transport they travel is given as:

                              Walk or bike    Bus       Car     Row Total

Below age 15            87                    60        18           165

Age 15 and above   65                    50        80         195

Column Total            152                  110        98         360

We know that a relative frequency of an event is the ratio of frequency to the total number of trials.

i..e we divide each frequencies by 360 to obtain a two-way relative frequency.

Hence,the table is given as:

                              Walk or bike    Bus       Car     Row Total

Below age 15            0.24               0.17      0.05         0.46

Age 15 and above    0.18                0.14      0.22        0.54

Column Total             0.42               0.31     0.27          1
