27 and 28 because their sum is 55 and 28-27=1
Answer:
x = 50°
Step-by-step explanation:
Recall that for a triangle, the exterior angle is equal to the sum of its two remove interior angles (also see attached for reference).
in our case, the exterior angle is given as 105° and its two remote interior angles are x and 55°
therefore
105° = 55° + x
x = 105° - 55°
x = 50°
Answer:
3 1/3 . 5-2=3 and 2/3 - 1/3 = 1/3. All together is 3 1/3
Answer:
Step-by-step explanation:
Given: Sample size: n = 41
Sample mean degrees
Population standard deviation degrees
Confidence level (c) = 80% =0.80
Significance level (a) = 1- c = 1-0.80 = 0.20
z-score for 80% confidence level : z = 1.2816 [from z-table]
Confidence level for population mean :-
Hence, 80% confidence interval for the temperatures in the freezer
Answer:
y = -7/6x
Step-by-step explanation:
y - y1 = m*(x-x1)
m=y/x
y - (-7) = -7/6*(x-6)
y + 7 = -7/6x + 7
y = -7/6x + 7 - 7
y = -7/6
