Answer:

She spends 2 hours driving.

Step-by-step explanation:

The formula given is:

d = rt

In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.

Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.

This means that d = 80, r = 50

To the nearest hour, how many hours does she spend driving?

We have to find t. So

d = rt

50t = 80

t = \frac{80}{50}

t = 1.6

Rounding to the nearest hour

She spends 2 hours driving.

fgiga [73]

Answer:

D - Type of restaurant - fast food or more expensive.

Step-by-step explanation:

By a lurking variable we mean or refer to any variable that is unknown and not controlled for or out of individual control. When there is one or more lurking variables in any study it could results in accidental bias. According to Soares (1985), lurking variables are intrinsic and they are not actually caused by “accidents” in real sense. Hence he suggests that “lurking-variable bias” is a more suitable name for accidental bias.

Concluding that individuals who spend a lot on groceries also spend a lot at restaurants could be misleading in the sense that, groceries may have a more uniform price than restaurant regardless of your social class. For instance, type of restaurant could determine food cost. At some restaurant, food is quite expensive at another food is quite affordable. I may not to go any groceries store in a month but I patronize restaurant to eat daily.

It is also possible I don't patronize restaurants! And yet, I am frequent at groceries store.

In real sense, what I spent at groceries might be nothing compare to what I spend at restaurant and vice versa. Hence, the possible lurking variable is type of restaurant - fast food or more expensive which is unknown and not controlled for.

Kay [80]
I'm not sure why options a. and d. are the same, but you would simply count the number of times x and m appear, while being multiplied together, and multiply the product of xm by that number. in this case, the number is 7, so you should get 7(xm) or 7xm.
