Answer:
area = 132 cm²
Step-by-step explanation:
area of rectangle = 7 x 12 = 84
area of one triangle = 8 x 6 x 0.5 = 24
total area = 84 + 24 + 24 = 132 cm²
F-1(x) = (x-7) / 2, you can get this by taking 2x + 7, and doing the opposite operations on x. you also need to go in the reverse direction of Order of Operations. So first, we take 7 away from x, since subtraction is opposite from addition, and it is the last thing we would do in order of operations. next we only have the 2 multiplier left, so we put the x-7 in parenthesis, and divide by 2.
Put the numbers in order
6,7,15,36,41,43,47,49
Q1 = (7 + 15) / 2 = 22/2 = 11 <== first quartile
Q2 = (36 + 41) / 2 = 77/2 = 38.5 <== median
Q3 = (43 + 47) / 2 = 90/2 = 45 <== third quartile
difference of largest value and median.....(49 - 38.5) = 10.5
Answer: F(x)=e^x-2+9
Step-by-step explanation: for plato users
Information given:
- <u>100 passengers in each train car</u>
- <u>10 train cars total</u>
- <u>30 trains total</u>
<em>So we are trying to find the total number of passengers on all 30 trains?</em>
<u />
Step-by-step:
100 x 10 = <u>1,000 passengers per train</u>
1,000 x 30 = <u>30,000 passengers total within the 30 trains</u>
Answer: <u>30,000 passengers</u>
<em>Hopefully this answered your question :)</em>
