Answer: The net change would be -2.
Step-by-step explanation: The upward change of elevator is represented by positive sign while the downward change represented by negative sign.
Given, First the elevator goes up 15 floors, change = + 15, Then it goes 9 floors down, change = -9, Then it goes 11 floors up,Change = + 11, Finally, it goes 19 floor down, Change = - 19 So, the net change = sum of total changes = 15 - 9 + 11 - 19 = -2

Find the volume of each figure, round to nearest tenth
Answer:
These are the answers
Step-by-step explanation:
The volume of a sphere formula is:
V = 4/3 x pi x r cubed
V = 4/3 x 3.14 x 6 cubed
V = 4/3 x 678.24
V = 4/3 x 678.24/1
V = 2712.96/3
V = 904.32 cubic cm
So 904.30 cubic cm would be the volume.
the radius is 6
the diameter is 12
and i am guessing the height is also 12 since a sphere is perfectly round
Darrin tosses a quarter and a penny 20 times. He gets heads on both coins
twice. Compare the theoretical probability of getting heads on both coins
with Darrin’s experimental probability of getting heads on both coins. Why
might the probabilities differ?
Answer:
The 4 possible outcomes are HH, HT, TH, TT.
So theoretically, HH should occur 1in 4 times.
1/4 = x/20
x = 5
So why is it actually 2 in 20 when theoretically it should be 5 in 20? One reason is that theoretical probabilities gain more accuracy with larger numbers of results (e.g tossing the coins 100 times). You can likely think of some more reasons.

Find the product and write the answer in decimal form.
(6.5) (2 4/5)
The product of (6.5) and (2 4/5) is 91/5 and after converting in decimal it is approximately 18.2.
To find the product of (6.5) and (2 4/5), we need to convert the mixed number into an improper fraction.
First, we convert the mixed number 2 4/5 into an improper fraction:
2 4/5 = (2 × 5 + 4)/5 = 14/5
Now, we can multiply 6.5 by 14/5:
(6.5) × (14/5) = (6.5 × 14)/(1 × 5) = 91/5
To get the answer in decimal divide it further: 91/5 ≈ 18.2
Therefore, the product of (6.5) and (2 4/5) is approximately 18.2.

How many different 4-digit numbers can be created if no digit can be
repeated? Remember, a number cannot begin with 0.
Answer:
2
Step-by-step explanation:
1234
4567
Explanation:
There are ten single digit values 0 through 9. But we cannot use 0 as the first digit, so we have 9 possible choices for the first slot.
For the second slot, we also have 9 choices because we can now pick 0.
The third slot has 8 choices.
The last slot has 7 choices.
Each time we form a new slot, the number of choices drops by 1. The exception of course is the jump from the first to second slot.
Overall, there are 9*9*8*7 = 4536 different numbers.
