Answer:
253,000
Step-by-step explanation:
- Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
- 2.1 × 100,000 = 210,000
- Plug 210,000 in: 210,000 + 4.3 × 10,000
- 4.3 × 10,000 = 43,000
- Plug 43,000 in: 210,000 + 43,000
- 210,000 + 43,000 = 253,000
I hope this helps!

Answer: Choice C</h3>
P = 11/40 + 1/4 - 1/20
=========================================================
Explanation:
The formula we use is
P(A or B) = P(A) + P(B) - P(A and B)
In this case,
- P(A) = 22/80 = 11/40 = probability of picking someone from consumer education
- P(B) = 20/80 = 1/4 = probability of picking someone taking French
- P(A and B) = 4/80 = 1/20 = probability of picking someone taking both classes
So,
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 11/40 + 1/4 - 1/20
which is why choice C is the answer
----------------
Note: P(A and B) = 1/20 which is nonzero, so events A and B are not mutually exclusive.
1/4 off means 0.25 * 28
7
Sale price = 28-7
= 21
I would think the answer is -16
but that's is what i think
It is easier to write the equivalent ratios first, then use that information to find the missing values.
3. ratio: cars/trucks = 3/5, or trucks/cars = 5/3. Missing value: 6/3*5 = 10.
4. ratio: TVs/Computers = 2/7, or Computers/TVs = 7/2. Missing value: 21/7*2 = 6.
