Option B is a true statement in regards to highways miles per gallon and class of the car.
<u>Step-by-step explanation</u>:
- Option B is correct because full-size cars have the smallest standard deviation than compact cars. Compact cars are larger than full size cars. Very few in sub compact cars have larger size.
- Full size cars are not distributed uniformly. Each cars are in different sizes. So it is not uniform.
- We can make statements about standard deviation from these graphs by calculating it.
Answer:
4 pints
Step-by-step explanation:
The conversion from pint to ounce is:
1 pint = 16 ounces.
The teacher collected 19 pints, that is, 19*16 = 304 ounces of lake water.
If there are 60 students, and each of them use 4 ounces, the total of lake water used is 60*4 = 240 ounces.
So, the amount of lake water left is 304-240 = 64 ounces, that is, 64/16 = 4 pints.
Answer: Greater than 3,200 and less than 4,000
Step-by-step explanation:
50 * 78 = 3,900
Find what that area is
22*66=1452
5 times of that is
1452*5=7260
s=seconds
(22+33s)(66+33s)=7260
1089s^2+2904s+1452=7260
minus 7260 from both sides
1089s^2+2904s-5808=0
factor or use quadratic formula
(363)(x+4)(3x-4)=0
set each to zero
x+4=0
x=-4, false, it is increasing, not decreasing
3x-4=0
3x=4
x=4/3
answer is 4/3 seconds
