Answer: 5/6
Step-by-step explanation:
Find the greatest common factor. I’m this case, the greatest common factor is 9. Now divide both the numerator and denominator by 9. You would get 5/6
Answer: The interval is 0.9 ± 0.0259 and margin of error is 0.0259
Step-by-step explanation: <em>Confidence interval for a proportion in one sample</em> is the estimate of the proportion of a population. It is calculated following the next steps:
1) Find the proportion , in which x is the number of people with the desired condition. In our case, p=0.9;
2) Calculate margin of error, i.e.:
z is z-score, which for a 95% confidence, equals 1.96;
Substituting with the data given:
= 0.0259
3) Write: p ±
In our case, the interval will be 0.9 ± 0.0259.
<u><em>Margin</em></u><em> </em><u><em>of</em></u><em> </em><u><em>error</em></u> is the random sampling error in the results of a survey, i.e.,it shows you how far your result will be from the real value. For the Harris poll, margin of error is 0.0259
Answer: its 4. Look at the graph, x is horizontal and y is vertical (first go sideways then go up.) if coordinates are x,y then first go sideways when looking for x. they give you x. 7. then we go up. the graph intersects 7 at 4, therefore the coords are 7, 4 and your y coordinate is 4.
Step-by-step explanation:
First lets convert the pints to cups.
1 pint = 2 cups
12 pints = ? cups
Now lets multiply to find out how many cups are in 12 pints.
12 × 2 = 24
24 cups in 12 pints.
Now lets look at the information we have.
4 cups of water per 9 servings
Now lets divide to see how many time 24 goes into 4.
24 ÷ 4 = 6
Now lets multiply:-
6 × 9 = 54
So, 54 servings of water fir in 12 pints of water.
