You can multiply the fraction by any number you want so you gonna have an other fraction that is equal to your fraction like : 3 × 2 / 5 × 2 = 6 /10 so 3/5 = 6/10 :)))
i hope this be helpful
have a nice day
Answer:
20
Step-by-step explanation:
first plug it in, then solve. Step by step:
3(5 + 2) - 1
3(7) - 1
21 - 1
20
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:
226 cm^2
Step-by-step explanation:
It’s literally a rectangular prism If you put it together. The side with 2 cm and 11 cm , the surface area is 22 and since this is a rectangular prism, that means there is a second of the same kind. Then you get the larges box, since you know that the top side is 11 and the left side is 7, you multiply that * 2 which you then get 154. You add that up with the side that you solved before so 154 + 44 = 198. You then figure out the left side 7 * 2 * 2 (because there are two of them). 28 + 198 = 226 cm^2.
