Answer:
(-16x + 13)° + (-20x + 23)° = 180° (ángulo recto)
-16x° + 13° - 20x° + 23° = 180°
-36x° + 36° = 180°
-36x° = 180° - 36°
-36x° = 144°
-x° = 144°/(-36)
x° = 36°

The least number of times that two planes can cross is zero, since parallel planes do not intersect. A good example would be a floor and a ceiling, which run parallel, hence they do not meet. Conversely, if two planes occupy the same space, they can intersect at infinitely many points, as could happen with a line within that plane.
Answer:
The response is "I made an error."
Step-by-step explanation:
It's not possible to have a negative probability; it must always be zero or greater.
Answer:
160/1001, 175/1001
Step-by-step explanation:
i) We calculate:
₈C₁ methods to select 1 new camera from a selection of 8
₆C₃ methods to select 3 refurbished cameras from a selection of 8
₁₄C₄ methods to select 4 cameras from the total of 14 cameras
The probability formula is:
P = ₈C₁ ₆C₃ / ₁₄C₄
P = 8×20 / 1001
P = 160 / 1001
P ≈ 0.160
ii) For at most one new camera, it means we want either one new camera or none at all. We've calculated the probability of selecting one new camera already. The probability of not selecting any new camera is equivalent to selecting 4 refurbished cameras:
P = ₆C₄ / ₁₄C₄
P = 15 / 1001
Therefore, the combined probability is:
P = 160/1001 + 15/1001
P = 175/1001
P ≈ 0.175
The total revenue amounts to $32.13. A breakdown of this revenue shows that both types of tomatoes were sold for $1.70 per pound, with one customer purchasing 10.6 pounds of red tomatoes and 8.3 pounds of green tomatoes. Thus, the total revenue is calculated as follows: Total revenue = 1.7*10.6 + 1.7*8.3, leading to the total of $32.13.
