Answer:

Option B is correct

The median of the following string of values is 52

Step-by-step explanation:

Median defined as the median is the middle number.

To find the median of the following string of values:

55, 18, 58, 49, 8, 77, 62, 26, 7, 91

Arrange the string of values from least to greatest.

7, 8, 18 , 26, 49, 55, 58, 62, 77, 91

As you can see that we have two numbers, there is no middle number.

Simply, take the mean of the two middle numbers.

then;

Median = $\frac{49+55}{2} = \frac{104}{2} = 52$

Therefore, the median of the following string of values is 52

The median is 52, so the answer would be B.

Two bicyclists are 180 miles apart when they start racing towards each other. If their speeds are 14 mph and 16 mph respectively

bija089 [108]

So first what you want to do is find out how much closer they would be after one hour. Since they're both moving towards each other, that means they gain,

14 + 16 = 30 m in one hour.

(because they're both moving towards each other, so for the amount they get closer to each other, you want to add both of their speeds)

Since they were originally 180 miles apart, and you want to find how long it would take for them to be 20 miles apart, you want to just subtract 20 from 180 to find the total distance they have to travel.

180 - 20 = 160

Now divide 160 by 30 to find out how many sets of 30 miles, or one hour time periods, there are in 160 miles.

160 / 30 = 16/3 hours.

To make this into minutes, you can just multiply by 60.

16/3 * 60 = 960/3

960/3 = 320

So it'll be 320 minutes before they are 20 miles apart.

Suppose that f(x)=x2 and g(x) =4/5x2. Which statement best compares the graph of f(x)?

Roman55 [17]

Answer:

See below.

Step-by-step explanation:

Are f(x)=x2 and g(x) =4/5x2 correctly written?

This answer assumes they are supposed to be:

f(x)=x^2 and g(x) = (4/5)x^2

If these revisions are correct, g(x) would produce values that are (4/5) of f(x).
