Answer:
m=4
Step-by-step explanation:
Since we know that quadrilateral ABCD is similar to QRST, we know that the side lengths will be proportional to one another. As such, we should take a ratio to determine the side length of m.
m=4
<span>|x + y| + |z| = </span><span>|-6 + 4| + |-13| = </span><span>|-2| + 13 = 2 + 13 = 15</span>
Answer:
the last one (bottom right)
Step-by-step explanation:
4×pi is the same as twice around the whole circle to the beginning. it is the same as 0°, and cos(0) = 1, and then -2×cos(0) = -2
so, we only need to look, where the function reaches -2.
it should be at x = 0, x = 0.5 and x = 1.
Answer:
20%
Step-by-step explanation:
Use the formula:
The "|" symbol represents absolute value and the dashed line represents a division line.
| Theoretical Value - Actual Value |
Percent Error = -------------------------------------------------- × 100
| Theoretical value |
- 100 students is the theoretical value
- 120 students is the actual value
100 - 120 = -20
-20 / 100 = -0.2
|-0.2| = 0.2
0.2 × 100 = 20
The answer is 20%
