What is the median of the data?

1 answer:

8 0

20, 19, 13, 23, 16, 15, 17, 17, 15, 15, 22, 19

To find the Median, place the numbers in value order and find the middle.

13, 15, 15, 15, 16, 17, 17, 19, 19, 20, 22, 23

There are 12 numbers and so we don't have just one middle number, we have a pair of middle numbers:

13, 15, 15, 15, 16, (17, 17), 19, 19, 20, 22, 23

To find the value halfway between them, add them together and divide by 2:

17 + 17 = 34
34 ÷ 2 = 17

So the median is A) 17.

Train a is traveling at 30 mph faster than train b. If train a travels 350 miles in the same amount of time that train b travels

GalinKa [24]

Answer:

20 mph

Step-by-step explanation:

Let speed of Train a = Va mph

Let speed of Train b = Vb mph

Va = Vb + 30

Let time taken for Train a = Ta

Let time taken for Train b = Tb

time taken = distance travelled/speed

Ta = 350/Va = 350/(Vb+30)

Tb = 140/Vb

But they both travel in the same amount of time.

So, Ta = Tb

$\frac{350}{v_{b} + 30}=\frac{140}{v_{b}}$

Cross multiply

$350v_{b} = 140(v_{b} + 30)\\\\350v_{b} = 140v_{b} + 4200\\\\350v_{b} -140v_{b} = 4200\\\\210v_{b} = 4200$

Divide both sides by 210

$\frac{210v_{b} }{210} \frac{4200}{210} \\\\v_{b} = 20 mph$

How much is 1.4 kg minus 650 grams

faltersainse [42]

First of all you have to convert kg to grams

so there is 1 kg in 1000g
.4 kg is 400g
1000+400= 1400g

1400-650 = 750 kg

that's your final answer

Draw Conclusions The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3? Explain

Anon25 [30]

Answer:

The product represent the number $3\times 0.3=0.9$

Step-by-step explanation:

To find : The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3?

Solution :

0.3 represents $0.3=\frac{3}{10}$

0.9 represents $0.9=\frac{9}{10}$

If we multiply 0.3 by 3 we get 0.9

As, $3\times 0.3=3\times \frac{3}{10}$

$3\times 0.3=\frac{9}{10}$

$3\times 0.3=0.9$

Therefore, The product represent the number $3\times 0.3=0.9$

Find the circumference and the area of a circle with radius 9 km

NeX [460]

Answer:

Circumference= 56.52km Area=254.47km

Step-by-step explanation:

To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area.

The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle).
