Order the expressions by choosing or

order the expressions by choosing or A: – Concept: Use a truth-based partial order.For Boolean expressions E and F, define E ≤ F if every assignment that makes E true also makes F true (i.e., the truth set of E is a subset of the truth set of F).In this order, adding OR tends to […]

Based on the measurements shown on abc ab must be

based on the measurements shown on abc ab must be A: Concept: Triangle inequality.In any triangle with sides AB, BC, CA, AB must satisfy |BC − CA| < AB < BC + CA. Example: If BC = 5 and CA = 4, then AB must be between 1 and 9 (i.e., 1 < AB < […]

Explain the causes and effects of acid rain in germany.

Causes – Concept: Acid rain occurs when sulfur dioxide (SO2) and nitrogen oxides (NOx) from burning fossil fuels react in the atmosphere to form sulfuric and nitric acids, which fall with precipitation.– Example: Coal-fired power plants in North Rhine-Westphalia in the 1970s–80s released high SO2/NOx, driving acidic rainfall across western Germany.Effects – Concept: The acids […]

The circle graph above gives the distribution of salad dressing

– Concept: A circle graph (pie chart) shows how a whole is divided among categories; each slice’s size is proportional to that category’s share (percent of the total or a corresponding angle in degrees).– One clear example: If the circle graph for salad dressings has Ranch 40%, Caesar 25%, Italian 20%, and Vinaigrette 15%, then […]

In jkl and pqr if jk pq

– Concept: Caesar shift (fixed offset) in the alphabet.With a +6 shift, each letter moves 6 places forward (mod 26).This makes JK map to PQ, and JKL map to PQR.– Example: JKL → PQR (J→P, K→Q, L→R). So JK → PQ as part of that shift.– Brief example: ABC → GHI (A→G, B→H, C→I) under […]
