Answer:
YX and WX
Step-by-step explanation:
In an isoceles triangle, the sides WX and YX are equal which also means you can assume angle W and angle Y are also equal.

I can but where are the questions
Answer:
Width =15
Length =33
Step-by-step explanation:
Take width as x
And length as 2x+3
Perimeter as 96
Formula of the perimeter of a rectangle is 2l+2w
X+×+2×+3+2×+3=96
6x+6=96
6x=96-6
6×=90
X=15
Width =x and x =15 so width =15 while length =33
Answer:
0.85083 ; 0.83147 ; 0.6823 ; 0.015386
Step-by-step explanation:
Given that:
σ = 25
μ = 86
(a) x is more than 60
P(x > 60)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (60 - 86) /25
Z = - 1.04
P(Z > - 1.04) = 0.85083 (Z probability calculator)
(b) x is less than 110
P(x < 110)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (110 - 86) /25
Z = 0.96
P(Z < 0.96) = 0.83147 (Z probability calculator)
(c) x is between 60 and 110
P(x < 110) - P(x < 60)
P(Z < 0.96) - P(Z < - 1.04)
0.83147 - 0.14917
= 0.6823
(d) x is greater than 140
P(x > 140)
obtain standardized score (Zscore)
Zscore = (x - μ) / σ
Z = (140 - 86) /25
Z = 2.16
P(Z > 2.16) = 0.015386 (Z probability calculator)
