You'll have to substitute all the y's by 18, so our expression will stay like this:
18 - 2 =
16 = final answer

Answer:
See below
Step-by-step explanation:
1 . Missing angle
Sum of interior angles in the triangle = 180°
- 180° - (105° + 29°) = 36°
2. Angle 1
- Angle 1 is exterior angle of the triangle
- Angle 1 = 55° + 78° = 133°
3. Angle 2
- Angle 2 = 180° - (55° = 78°) = 47°
4. The sum of exterior angle and adjacent interior angle equals 180°
If they are equal, then each will measure 180°/2 = 90°
So it is possible with the right triangle

Answer:
The upper limit of the 95% confidence interval is:
C.I_u = 200 + (58.8/
)
Step-by-step explanation:
The formula is given as:
C.I = μ ± Z*σ/
The upper limit => C.I_u = μ + Z*σ/
The lower limit => C.I_l = μ - Z*σ/
The sample size (n) is not stated in the question. Hence, we calculate the upper limit with respect to n.
The upper limit => C.I_u = 200 + 1.96*(30/
)
= 200 + (1.96*30)/
= 200 + 58.8/
6.70 multiplied by 112 = 750.40
