Ok so every 2m= 1cm. So you have to divide your side lengths (4 and 6) by 2m in order to find out how many centimetres. 4/2 is 2 and 6/2 is 3 so you have side lengths of 2com and 3cm.
So your lengths was 6m, now it’s 3cm.
And you width was 4m, now it is 2cm
Answer:
36 = 2x + y
x = y

Answer:
CI= [28.67,45.33]
Step-by-step explanation:
-Given the mean is $37 and the standard deviation is $17
#A 95% confidence interval can be calculated as follows:
![CI=\mu\pm z \frac{\sigma}{\sqrt{n}}\\\\=\mu\pm z_{0.025}\frac{\sigma}{\sqrt{n}}\\\\=37\pm1.96\times\frac{17}{\sqrt{16}}\\\\\\=37\pm8.33\\\\=[28.67,\ 45.33]](https://tex.z-dn.net/?f=CI%3D%5Cmu%5Cpm%20z%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D%5Cmu%5Cpm%20z_%7B0.025%7D%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D37%5Cpm1.96%5Ctimes%5Cfrac%7B17%7D%7B%5Csqrt%7B16%7D%7D%5C%5C%5C%5C%5C%5C%3D37%5Cpm8.33%5C%5C%5C%5C%3D%5B28.67%2C%5C%2045.33%5D)
Hence, the 95% confidence interval is [28.67,45.33]
Answer:
x = -5
Step-by-step explanation:
Simplifying
6x + -3(x + -8) = 9
Reorder the terms:
6x + -3(-8 + x) = 9
6x + (-8 * -3 + x * -3) = 9
6x + (24 + -3x) = 9
Reorder the terms:
24 + 6x + -3x = 9
Combine like terms: 6x + -3x = 3x
24 + 3x = 9
Solving
24 + 3x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-24' to each side of the equation.
24 + -24 + 3x = 9 + -24
Combine like terms: 24 + -24 = 0
0 + 3x = 9 + -24
3x = 9 + -24
Combine like terms: 9 + -24 = -15
3x = -15
Divide each side by '3'.
x = -5
Hope this Helps
I hope this is correct
