Answer: p = 0.56
Step-by-step explanation: from the question, probability she passed the first course = 0.7
Probability she passed the second course = 0.8
Probability she passes both courses means probability she passes the first course "and" probability she passes the second course.
Probability she pass both courses = 0.7 * 0.8 = 0.56
Note that "and" in probability means multiplication.
Answer:
x = 14
Step-by-step explanation:
See the diagram of the triangle attached.
We have Δ RST where, ∠ RST = 7x -54 and ∠ SRT = ∠ STR {Since, given that, RS = ST}
Now, if ∠ STU = 8x, then ∠ STR = 180 - 8x {Since, ∠ STU and ∠ STR are supplementary}
So, ∠ SRT = ∠ STR = 180 - 8x
Now, from Δ SRT, ∠ RST + ∠ SRT + ∠ STR = 180
⇒ 7x - 54 + 180 - 8x + 180 - 8x = 180
⇒ 9x = 126
⇒ x = 14 (Answer)
Answer:
S 36.87° E
Step-by-step explanation:
It moves in a certain direction determined by
(y/x) = arctan
arctan (-4/3) 306.87° arctan (-4/3) arctan (-4/3) arctan (-4/3) arctan (-4/3) arctan (-4/
S 36.87° is another way of describing this travel direction.
