4 1/4= 17/4
17/4 divided by 1/8= 17/4* 8/1= 136/4= 34
Therefore there are 34 eighths in 4 1/4.

The average daily maximum temperature in Syracuse is 21.85°C, and the average daily minimum temperature is -4.7°C. The average d

podryga [215]

By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.

<h3>What is the difference between the average daily maximum temperature and the average daily minimum temperature?</h3>

Herein we must find the difference bewteen the two temperatures, defined as the subtraction of the <em>minimum</em> temperature from the <em>maximum</em> temperature:

x = 21.85 °C - (- 4.7 °C)

x = 26.55 °C

By applying the definition of difference, we find that the <em>average daily maximum</em> temperature in Syracuse is 26.55 °C higher than the <em>average daily minimum</em> temperature.

A hollow metallic cylinder is made from a metallic sheet of 2.4 cm thickness. The inner

butalik [34]

Answer:

The volume of the metal used is 5277.9 cm³.

Step-by-step explanation:

The volume of a cylinder is given by:

$V = \pi r^{2} h$

Where:

r: is the radius

h: is the height = 50 cm

The volume of metal ( $V_{m}$ ) can be found by subtracting the internal volume ( $V_{i}$ ) from the external volume ( $V_{e}$ ):

$V_{m} = V_{e} - V_{i}$

$V_{m} = \pi r_{e}^{2} h - \pi r_{i}^{2} h$

The external radius is given by the sum of the internal radius with the tickness:

$r_{e} = t + r_{i}$

Hence, the volume is:

$V_{m} = \pi*50 cm((2.4 cm + 5.8 cm)^{2} - (5.8 cm)^{2}) = 5277.9 cm^{3}$

Therefore, the volume of the metal used is 5277.9 cm³.

I hope it helps you!

A simple random sample of 60 items resulted in a sample mean of 80. The population standard deviation is σ = 15. a. Compute the

Kaylis [27]

Answer:

a) (76.21,83.79)

b) (77.32,82.68)

c) Interval decreases

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 60

Sample mean = 80

Sample standard Deviation, s = 15

a) 95% Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$80 \pm 1.96(\dfrac{15}{\sqrt{60}} ) = 80 \pm 3.79 = (76.21,83.79)$

b) Sample size, n = 120

95% Confidence interval:

$80 \pm 1.96(\dfrac{15}{\sqrt{120}} ) = 80 \pm 2.68 = (77.32,82.68)$

c) As observed increasing the sample size, the confidence interval become smaller.
