With these fives things below, can you advise if qualitative or quantitative, next whether discrete or continuous, and last whether nominal, ratio, ordinal, or interval. 1. letter grade (a – f), 2. bathtub capacity (gallons), 3. relationship status, 4. shoe size, and 5.class standing (fr/so/jr/sr)

2 what are the four variables in the study description below? determine whether each is quantitative or qualitative; discrete or continuous; and the level of measurement.

in order to determine how several small local streams react to a variety of weather conditions, researchers collected data at twelve different sites over the past year. among those data, the researchers took daily readings of the amount of rain (in inches) that had fallen in the past 24 hours, and the flow of the streams (in cubic feet per second) at a specific time each day. reference materials available provided the research team with an ecological health grade for each stream (from a down to f) and the stream’s "order", which is the number of streams that feed into it (values range from 0 to 11). conclusions are expected to assist in the planning of development along local streams and in the restoration of other similar streams.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
