Answer: 120

Step-by-step explanation:

The median of a given set for numbers will be gotten when we arrange the numbers that are given in either ascending or descending order and then get the number in the middle.

Therefore, since we are given 90,100,120,120,140, it means that we have 5 numbers and the 3rd number will be the median distance. Thus will be: = 120

Mary has 12 marbles 3/12 of the marbles are yellow 2/12 of the Marvels are blue The rest of the marbles are green How many marbl

Oxana [17]

Answer: 7 marbles are green.

Step-by-step explanation:

Since we have 12 marbles in total, 12/12 = 1. Since the fractions have denominators of 12 as well, we can easily tell there are 3 yellow marbles (3/12) and there are 2 blue marbles (2/12).

Lastly, we need to find how many are green. We can subtract the yellow and blue marbles from the total of 12 marbles.

12 - (3 + 2)

12 - (5)

7 marbles are green.

In a trolley ride around an amusement park, a child traveled from one signpost to a second signpost at a constant speed of 125 m

Inessa05 [86]

Answer:

Given speed of trolley = 125 meters per minute

$Speed= 125 meters/minute\\\\Speed =\frac{125}{60}meters/second\\\\Speed=2.083m/s$

Now we know that

Distance= Speed x time

Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than

Distance < 2.083 x 450 =937.5 meters

hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.

For the second case

since the time of travel is greater than 400 seconds

Thus the distance traveled is

$Distance>2.083\times 400=833.2meters$

which is greater than 800 meters.

What is a1 for the geometric sequence for which a8= -3584 and a3 = 112 ?

jasenka [17]

Answer:

The first term is 28.

Step-by-step explanation:

Given: 8th term of Geometric sequence , $a_8=-3584$

and 3rd term of Geometric Sequence, $a_3=112$

We have to find First term of given geometric Sequence.

Let a be the first term of geometric sequence.

We know that,

$a_n=ar^{n-1}$

So,

$\frac{a_8}{a_3}=\frac{ar^{8-1}}{ar^{3-1}}=\frac{-3584}{112}$

$\frac{r^{7}}{r^{2}}=-32$

$r^5=-32$

$r=-2$

So, $a_3=112$

$a\times(-2)^{2}=112$

$a=\frac{112}{4}=28$

Therefore, The first term is 28.
