Cíiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Answer is 8/10 because the original fraction was 4/5 and they had 10 pizzas and that would be the denominator so you have to get the denominator to be 10 so you would multiply 4/5×2 and you would get 8/10 and since the denominator is 10 that is your answer think of it like this... part at the top whole at the bottom hope this helps
The solution would be like this for this specific problem:
Given:
N = 256
Sample Mean = $35,420
Standard Deviation = $2,050
Find:
Standard Error of Mean = ?
The
formula for the standard error of the mean is:
<span>Om
= o / sqrt(N)</span>
<span>Om
= the </span>standard deviation of the sampling
distribution of the mean
where
o = standard deviation of the sampling distribution of a statistic
N
= sample size
<span>So
substituting the formula with the given:
Om = $2,050 / sqrt(256)</span>
<span>Om
= $2,050 / 16</span>
= $128.125
Therefore, the sample standard error of the mean is
$128.125.
Answer:
A
Step-by-step explanation:
Let C represent the temperature in Celsius, and let F represent the temperature in Fahrenheit.
F=1.8C+32
Using that equation, plug in the numbers. F=1.8*25+32. F=77
