14.5%
= 14.5/100
= 0.145 ≠ 14.5

So 14.5% is not equal to 14.5, and your friend is wrong~

14.5% = 0.145 = 145/1000

14.5 = 14500/1000

<span>So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.</span>

The confidence interval formula is computed by:

Xbar ± Z s/ sqrt (n)

Where:

Xbar is the mean

Z is the z value

S is the standard deviation

N is the number of samples

 

So our given are:

90% confidence interval with a z value of 1.645

Sample size 40, 45

Mean 180, 179

Standard deviation 2, 4

 

So plugging that information in the data will give us a confidence interval:

For 1:

Xbar ± Z s/ sqrt (n)

= 180 ± 1.645 (2 / sqrt (40))

= 180 ± 1.645 (0.316227766)

= 180 ± 0.520194675

= 179.48, 180.52

For 2:

Xbar ± Z s/ sqrt (n)

= 179 ± 1.645 (4 / sqrt (45))

<span>= 179 ± 1.645 (0.596284794)</span>

therefore, the answer is letter b

Which kind if triangle is shown? (1point)
Salsk061 [2.6K]
Hey there! :D

None of the sides are equal. We can tell this by just looking at it. If the side BC was a straight side, it would be a right triangle, but it is not. It doesn't have any right angles. 

It is a scalene triangle. It has no equal sides and no equal angles.

I hope this helps!
