Answer:

Step-by-step explanation:

median: The middle number after the numbers have been sorted into ascending or descending order.

Mean: The quotient of the numbers added together then divided by the amount of numbers.

So if 9 were the missing number the median would be 5 because in ascending order it would look like this:

1, 3, 5, 7, 9

and as you can see 5 is in the middle.

The mean would also be 5 because

1+ 3+ 5 + 7 +9 =25

and 25 divided by 5 equals 5

So therefore the missing number must be 9.

(Also it was obvious that they just added 2 to each number)

Answer:

Step-by-step explanation:

Complementary angles are two angles whose measures add to 90°.

m<CFD = 150° - 100° = 50°

m<EFD = 180° - 150° = 30°

Sum = 80°

m<AFB = 40°

m<DFE = m<EFD = 30°

Sum = 70°

m<AFC = 100°

Sum > 100°

m<BFC = 100° - 40° = 60°

m<DFE = 30°

Sum = 90°

Yes

I need help with an Algebra question. The question is in the picture. Thank you <3

The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is $0 \le t \le 165$

-------------------------------

The range is $0 \le H \le 40000$ since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.

Answer:

Step-by-step explanation: 3root5x^2 + 25x - 10root5 = 0

3xroot5 + 25x - 10root5 = 0 [ root x^2 = x]

28x root5 = 10 root5 [ -10root5 turns to 10 root5 when transferred to RHS]

28x root 5/root5 =10

28x=10

x = 10/28

x = 0.35

Hope it helped u,
