Furkat [3]

Answer:

n = 6

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal, that is

\frac{GH}{QR} = \frac{FH}{PR} , substitute values

\frac{n}{9} = \frac{4}{6} ( cross- multiply )

6n = 36 ( divide both sides by 6 )

n = 6

gtnhenbr [62]

Answer:

99\% CI=4.1602 \pm 0.0009

Step-by-step explanation:

From the question we are told that:

Sample size n=8

Mean \=x=4.1602

Standard deviation \sigma=0.001gram

Generally 99\% confidence from table  is mathematically given by

 99\% CI=4.1602 \pm *2.576*\frac{0.001}{\sqrt{{8}}}

 P(-z

 Z_{\alpha/2}=2.576

Generally the equation for 99\% confidence level (CI)  is mathematically given by

 99\% CI=\=x \pm Z_{\alpha/2*\frac{\sigma}{\sqrt{{n}}}

 99\% CI=4.1602 \pm 0.0009
