Step-by-step explanation:
first identify the common difference
The first term which i will define by u⁰=-27
u¹=u⁰+(1)d where d is the common difference and u¹ is the second term
u¹=-27+d
-11=-27+d
d=27-11=16
The 72nd term would be u⁷¹ since we started from u⁰ as our first term:
Use the explicit relation given by:
u(n)=u⁰+(n)d
u(71)=-27+71(d)
u⁷¹=-27+71(16)
u⁷¹=-27+1136
u⁷¹=1109
Can you show us the number line model?
A cylinder has two bases and a height that (unless oblique) runs right along a side, while a cone has one base and whose height begins at the center of its base and goes straight up to the peak.
Answer:
Rick ran 5.6 miles on Thursday.
Step-by-step explanation:
Let's first find the speed Rick ran on Wednesday.
D=RT
4.2 = (3/4)R
R = 5.6 mph.
D=RT
D=(5.6 mph)(1)
D=5.6 miles

For the answer to the question above,
<span>Sample mean is given by,
x = (1/n)∑x˅i .... ˅ means sub
x = (1/5)(60 + 40 + 35 + 45 + 39)
= 43.8
z-score is given by,
z = (X - μ)/σ .... μ is population mean, σ is the standard deviation
z = (43.8 - 43.8)/8.7
= 0
</span>so the answer is zero
I hope my answer helped you.
