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/

Answer:
<h2><em><u>320</u></em><em><u>0</u></em><em><u> </u></em><em><u>cm</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Length of the rectangle = 12 meters = 1200 cm
Width of the rectangle = 400 cm
<em><u>Therefore</u></em><em><u>, </u></em>
Perimeter of the rectangle = 2(l+w)
= 2(1200+400) cm
= 2 × 1600 cm
= <em><u>320</u></em><em><u>0</u></em><em><u> </u></em><em><u>cm</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
y=42
Step-by-step explanation:
GJ is equal to LG which means that the ratio of them is 15:20 because HG=ML. This means that the equation is y+3=45. You want to isolate y by subtracting 3 from both sides. y=42.
Therefore, y=42.
