The height of the blue spruce was 45.
We find the mean by adding all of the data points and dividing by the number of data points. We will add the unknown value x and change the number we're dividing by to 7:
(160+320+100+110+200+220+x)/7 = 165
(1110+x)/7 = 165
Multiply both sides by 7:
1110 + x = 1155
Subtract 1110 from both sides:
x = 45
A) 100 degrees (congruent angle)
B) 45 degrees (congruent angle)
C) 90 degrees (right angle)
D) 99 degrees (congruent angle)
E) 30 degrees (congruent angle)
F) 30 degrees (180-150=30, that is to find the other angle that is congruent to f)
Answer:
A. 2.40
B. 4
C. Costco is the better deal
Step-by-step explanation:
23.99/10= 2.399 (rounded to 2.40)
10/2.5 lbs (16 oz = 1 lb) = 4
C
If we drew a line of best fit, the gradient would be roughly equal to 1, and the y intercept would be at around -4
