Step-by-step explanation:
Answer:
Angle A is 77°
x = 3
AC = 13
Step-by-step explanation:
Angles A, B and C MUST add up to 180°. If Angle C is 26°, then the sum of A and B and 26° = 180°. In other words, A+B = 180° - 26° = 154.
Since A and B are equal, A = B = 154°/2 = 77°
Since this triangle is isosceles, sides AC and BC are equal. Thus,
7x - 8 = 3x + 4, or
4x = 12. Then x = 3.
Since AC = 7x - 8, and x = 3, AC = 7(3) - 8 = 21 - 8 = 13
Answer:
27
Step-by-step explanation:
the watch was alredy 19 seconds behind so you take 46 and subtract 19 and you get 27
The z-score is the number of standard deviations away from the mean. We first subtract the actual score from the mean, then divide the difference by the standard deviation. In this case, our actual score is 13, so we subtract from the mean of 16, then divide by the SD of 2
(13 - 16) / 2 = -1.5
Answer:
Qestion 1: First option.
Question 2: It's actually false, because we know that Eugene doesn't want to spend any more than 5, so 5 goes where the last x is.
Question 3: Last option.
Question 4: The order it's in seems correct, but I'm not 100% sure.
