Answer:

see explanation

Step-by-step explanation:

1 revolution is equivalent to the circumference of the wheel

1 revolution = πd ( d is the diameter )

= 70π cm

50 revolutions = 70π × 50 = 3500π cm = 35π m ≈ 110m ( nearest metre )

Answer:

109.956 m

Step-by-step explanation:

The first step is to find the circumference of the wheel.

C = πd

where d = diameter of the wheel

C = πd

= π × 70

= 219.9 cm.

In every revolution the bicycle move 219.9 cm.

In 50 revolution the bicycle will make = 219.9 × 50

= 10,995.6 cm

In meter = 10,995.6 ÷ 100

= 109.956 m

Answer:

Step-by-step explanation:

The trick here is to reduce each of the bases to lowest form first

$12 = 3.4 = 3 .2.2 = 3.2^{2}\\12^{3} = (3.2^{2} )^{3} = 3^{3}2^{6} \\6 = 3.2\\6^{5} = (3.2)^{5} = 3^{5} .2^{5} \\\\Numerator = 3^32^63^52^5 = 3^82^{11}\\Denominator computation\\9 = 3^2\\9^{4} = (3^{2} )^4 = 3^{8} \\Denominator = 3^82^{10} \\\\\frac{Numerator}{Denominator } =\frac{{3^8}{2^{11} }}{3^82^{10}} = \frac{2^{11}} {2^{10}} = 2^1 = 2$

Complete Question

The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. Test $H_o : p = 0.28$ vs $H a : p < 0.28$ when the sample has n 900 , and $\^ p = 0.216$ with $SE= 0.01$ . Find the value of the standardized z -test statistic. Round your answer to two decimal places.
