What is 2.23 as a fraction

2.23 as a fraction would be 2 and 23/100. Since the "3" is in the hundred<em>th</em>s place, the fraction has to be over 100. The 2 in front of the decimal point (.) is the whole number. That means 2.23 as a fraction would be 2 and 23/100.

Answer:

$Actual = 480\ miles$

Step-by-step explanation:

Given

$Map : Actual = 1\ in: 80\ miles$

Required

Find actual distance when map distance = 6 inches

Substitute 6 for Map in $Map : Actual = 1\ in: 80\ miles$

$6\ in: Actual = 1\ in: 80\ miles$

Express as fractions

$\frac{6\ in}{Actual} = \frac{1\ in}{80\ miles}$

$\frac{6}{Actual} = \frac{1}{80\ miles}$

Cross Multiply

$Actual * 1 = 6 * 80\ miles$

$Actual = 6 * 80\ miles$

$Actual = 480\ miles$

<em>Hence, the actual distance is 480 miles</em>

mote1985 [20]

<h2>Answer with explanation:</h2>

Given : In a restaurant, the proportion of people who order coffee with their dinner is p.

Sample size : n= 144

x= 120

$\hat{p}=\dfrac{x}{n}=\dfrac{120}{144}=0.83333333\approx0.8333$

The null and the alternative hypotheses if you want to test if p is greater than or equal to 0.85 will be :-

Null hypothesis : $H_0: p\geq0.85$ [ it takes equality (=, ≤, ≥) ]

Alternative hypothesis : $H_1: p$ [its exactly opposite of null hypothesis]

∵Alternative hypothesis is left tailed, so the test is a left tailed test.

Test statistic : $z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

$z=\dfrac{0.83-0.85}{\sqrt{\dfrac{0.85(1-0.85)}{144}}}\\\\=-0.561232257678\approx-0.56$

Using z-vale table ,

Critical value for 0.05 significance ( left-tailed test)=-1.645

Since the calculated value of test statistic is greater than the critical value , so we failed to reject the null hypothesis.

Conclusion : We have enough evidence to support the claim that p is greater than or equal to 0.85.
