The given sample's confidence interval is 4.73 ± 0.1199, or from 4.61 to 4.85
<h3>What is the z score?</h3>
The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.
Given data;
Mean = 4.73
Standard deviation = 0.865
Sample size = 200
interval = 95%
Confidence interval=?
95% of samples contain the population mean (μ) within the confidence interval of 4.73 ± 0.1199.
Hence, the sample's confidence interval is 4.73 ± 0.1199, from 4.61 to 4.85

Answer: 50° Fahrenheit
Step-by-step explanation:
Here, the equation that shows the temperature of x degree Celsius in Fahrenheit is,
Where x is a variable.
Thus, For the temperature of 10° Celsius,
x = 10° Celsius
The temperature in Fahrenheit is,
Thus, the increasing temperature by 10° C is equivalent to increasing temperature by 50° F.
Answer:
6.25 cups of water
Step-by-step explanation:
So I first write out the rates: 4:2.5 and also 10:?
So let's find out how the scoops changed, as in how did you get 4 to become 10 so you can do the same thing to 2.5 and get ?.
To go from 4 to 10 you MULTIPLY/DIVIDE. DON'T ADD OR SUBTRACT. 10 divided by 4 (to see what you multiplied by) is 2.5.
So we multiplied 4 by 2.5 to get 10. So if we multiply 2.5 by 2.5 we get 6.25.
So 4:2.5 = 10:6.25
?=6.25

Answer: x>-1/2y+7/2
Step-by-step explanation:
It is asking you to slice off 40% of the bounce height in each subsequent bounce.
So you start with full height 1, that's n = 0 bounces. Then after n = 1 bounce the new height is .6. After the second bounce, n = 2, the height becomes .6 X .6 = .36. And after n = 3, we have .6 X .6 X .6 = .216
So by induction we see that h(n = 5) = .6^n = .6^5 = 0.07776 = .078 of its original height or H = .078*200 = 15.6 ft. after five bounces. ANS. 16.0 if rounded to the nearest tenth
