I can only answer the second question :

on each side of the square is 90 degrees so

$130 - 90 = 40$

one triangle is 180 degrees (two fourties because of each edge of the triangle)

$40 + 40 = 80$

this is the answer

$180 - 80 = 100$

Question 18 Item 18 The distribution of the number of moths captured per night by a certain moth trap is approximately normal wi

juin [17]

Answer:

Standard deviation 46.3

Step-by-step explanation:

A 28% of the distribution is equivalent to a z score of -0.5828, you can use a z table to find that.

Z score is calculated as follows:

$z = \frac{x-\mu}{\sigma}$

x is the number being evaluated

μ is the mean

σ is the standard deviation

And it is used to calculate how many standard deviations you are from the mean of the sample.

Replacing with the known information you can calculate the standard deviation:

$\sigma=\frac{x-\mu}{z} =\frac{76-103}{-0.5828}= 46.3$

Step-by-step explanation:

3/2(19):x

3:2

3x = 2 * 3/2 * 19

3x = 57

x = 19

Since the ratio is 3:2, then the scores at half-time were 57:38
