Step-by-step explanation:
T1=a
T2=ar
r=T2÷T1
r=--18÷6
r=-3
T11=ar^10
T11=6×-3^10
T11=-354294
Answer:
17) #1 = 5
#2 = 49
18) Median= 50.5
Range = 88
Step-by-step explanation:
17) #1 - There are 5 3’s on the leaf side.
#2 - The number that is shown the most times is 49
18) There are 30 numbers in the stem and leaf plot, so the median falls between numbers 15 and 16. In this plot, those numbers are 50 and 51. So the median is 50.5.
The data ranges from 10 to 98. 98-10=88
Answer:
10x + 20
Step-by-step explanation:
5x + 10 +5(x) + 5(2)
= 5x+10 +5x +10
= 10x +20
Answer: 25° and 65°
Step-by-step explanation:
Let the smaller angle of the complementary angle be represented by x.
Since the other angle is 15 degree more than two times the other angle, this will be:
= (2 × x) + 15°
= 2x + 15°.
Then we add both angles together and equate them to 90° and this will be:
x + 2x + 15° = 90°
3x + 15° = 90°
3x = 90° - 15°
3x = 75°
x = 75°/3
x = 25°
Then the other angle will be:
= 2x + 15°
= (2 × 25°) + 15°
= 50° + 15°
= 65°
Therefore, the angles are 25° and 65°.
