Take a look at the picture provided

notice how there are 5 little sections to it

assuming each is the same height, you can take the 5 sections times the 6 ft man

5 x 6 = 30

therefore, the tower is 30 ft tall

(don't be mad if this is wrong)

A data set includes 103 body temperatures of healthy adult humans having a mean of 98.1degreesf and a standard deviation of 0.56

Karolina [17]

Answer:

The 99% confidence interval estimate for the mean is 97.9576 ≤ μ ≤ 98.246

A) This suggests that the mean body temperature could very possibly be 98.6 °F

Step-by-step explanation:

The number of body temperatures, n = 103

The mean body temperature, $\bar x$ = 98.1

The standard deviation, s = 0.56

Confidence interval required = 99%

Confidence interval, CI is given by

$CI=\bar{x}\pm z\frac{s}{\sqrt{n}}$

Plugging in the values we get;

z = 2.56 at 99%

$CI=98.1}\pm 2.56\times \frac{0.56}{\sqrt{103}}$

Therefore, we have

$\mu_{min} = 97.9579 , \ \mu_{max} = 98.242$ ,

The statistical result suggest that at 99% confidence level, the sample mean temperature is likely to be 98.1 °F

Sos please help me......

GenaCL600 [577]

Answer: 170

Step-by-step explanation:

Hemisphere volume formula

V = (2/3)πr3

(2/3)•(3.14)•(2.5)^3=32.7 (33)

Cylinder volume formula

V=πr^2h

(3.14)(2.5)^2(7)=137.4 (137)

137+33=170
