Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
2*4=8
2*d=2d
3*2=6
3*d=3d
Then collect like terms
8-2d=6+3d
2+5d
The z-score will be found as follows:
P(-z<Z<z)=0.18
P(-z<Z<z)=0.18/2=0.09
P(Z<0)=0.5
P(Z<z)=P(Z<0)+P(0<Z<z)=0.5+0.09=0.59
From the z-table, the z-value will be:
z=0.23
Answer:
The answer would be Z= -18
Step-by-step explanation:
Cause -18 - (-2) would be 16
