7.5 is your answer. 14.25 divided by 1.9 = 7.5
The angle measure is 30 degrees.
Drawing out an image, the angle the is between the ground at the hypotenuse (the slanted guy wire), it creates a triangle with the utility pole that was already on the side. The angle between the utility pole and the ground is obviously 90 degrees because it is assumed to be at a straight standing stance.
Normally these two given angles would be added and then subtracted from 180 degrees (the law of Sum of Angles in a Triangle).
60 + 90 = 150 ... 180 - 150 = 30
Also, this can be supported by the 30-60-90 Theorem, which states that if a triangle contains 2 of the 3 angles, the other angle will be the missing one.
Answer:
Step-by-step explanation:
during the day, it was -3.....at night it dropped 19 degrees...
so at night it is : (-3 - 19) = - 22 degrees Fahrenheit
Since the absolute value of the z-score is greater than the critical value, the statement is true.
<h3>When do we reject or do not reject the null hypothesis?</h3>
For a two-tailed test:
- If the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis.
- If it is more, we reject.
The critical value for a two-tailed test with 
is of |z| = 1.96.
In this problem, we have that Z = -2, hence |Z| = 2, which is greater than the critical value, hence we reject the null hypothesis and the statement is True.

Let's look at it like this:
5/10+1/5 = (5/10) + (1/5)
5/10 = 0,5
1/5 = 0,2
so it's 5/10 + 1/5 = (5/10) + (1/5) = 0,5 + 0,2 = <u>0,7 </u>
