Answer:
I would model and record finding the sum and difference of two rocks by calculating the weight and pound and it will be equal to the mass of that rock.
Step-by-step explanation:
Given that t<span>he
average commute time to work (one way) is 25 minutes according to the
2005 american community survey. if we assume that commute times are
normally distributed and that the standard deviation is 6.1 minutes,
what is the probability that a randomly selected commuter spends less
than 18 minutes commuting one way
The probability that a randomly selected number from a normally distributed dataset with a mean of μ and a standard deviation of σ is less than a value, x, is given by:

Given that the average </span><span>commute time to work (one way) is 25 minutes and that the standard deviation is 6.1 minutes,
the
probability that a randomly selected commuter spends less than 18

Answer: Right ,vertical, supplementary
Step-by-step explanation:In the given figure the two rays are perpendicular.A line is said to be perpendicular to another line if the two lines intersect at a right angle.Thus <1 and <2 are Right angles.
The opposite angles formed by two intersecting lines are called vertical angles.<1 and <2 are on opposite sides of the two rays and hence form vertical angles.
The angles made at the intersection of the two rays are 90 degrees .So the sum of angles 1 and angle 2= 90+90=180 degrees.When two angles add to 180 degrees they are called supplementary angles .
Hence <1 and <2 are Right ,vertical, supplementary angles.
Answer:
B. A hill that rises 2 feet for every 15 feet of run.
Step-by-step explanation:
The two must have COPs. We'll narrow them down.
For A, we divide 10 by 2.

For B, we divide 15 by 2.

B has the larger number, so it is B.
