Answer: No, it does not appear to be normal.
A normal distribution has very specific characteristics:
- it is bell-shaped: it starts at a low value, then it increases to a maximum value, then it decreases to a low value again;
- it is symmetric;
- it is single-peaked.
The data table is not complete, but it is enough to give an answer.
Let's see how the frequencies change: we have 2, 0, 4, 12,...
The frequencies start from a low value, but at first, they decrease to a lower value right before increasing to a maximum value.
We don't know how they change after the maximum value, but from the first part of the curve, we can see that it is not bell-shaped, because it decreases before increasing. Probably, it won't be symmetric either.
Hence, we can say that using a strict interpretation of the relevant criteria the frequency distribution does not appear to be normal.
Answer:
0,1.5
Step-by-step explanation:
y = 510 - 60x
We want to find the domain or the x values where x represents the time
We need to determine the possible values for x
Y cannot be greater than 510 or less than 0. 510 means they have not started the trip, and 0 means they have arrived
510 = 510 -60x
Subtract 510 from each side
510-510 = 60x
0 = 60x
The smallest value of x can be 0
0 = 510 - 60x
Subtract 510 from each side
-510 = 510-510-60x
-510=-60x
Divide by -60
-510/-60 = -60x/-60
8.5 = x
The maximum value of x is 8.5 hours
So x must be between 0 and 8.5 inclusive.
Answer:
A
Step-by-step explanation:
( 3x² + 4x + 4)(2x - 4)
(6x³ - 12x² + 8x² - 16x + 8x -16)
(6x³ - 4x² - 8x - 16)
Hope this helps!
Answer:
Inches,Foot ,Yards and Miles are customary unit used here.
Step-by-step explanation:
To convert the metric units to customary units.
We have,
Note:A centimeter, or centimeter, is a unit of length equal to one hundredth of a meter. There are 2.54 centimeters in an inch.
Note:A foot is a unit of length equal to exactly 12 inches or 0.3048 meters.
Note:A yard is a unit of length equal to 3 feet or exactly 0.9144 meters.
And
Note:A mile is a unit of distance equal to 5,280 feet or exactly 1.609344 kilometers.

So the customary units are inches,foot,yard and miles.
