The amount of pens he buys affects the amount he spends. (not vice versa)
independant = amt. of pens
dependant = amt. spent
Answer:
0.86 (Approx)
Step-by-step explanation:
Given:
n = 35
P = 55% = 0.55
Q = 1 - p = 0.45
Computation:
Standard deviation σ = √npq
Standard deviation σ = √(35)(.55)(.45)
Standard deviation σ = 2.9432
Mean μ = np = 35 x 0.55 = 19.25
p[(x-np)/ σ ]
P[z<1.04204]
= 0.86 (Approx)
The answer is that x is equal to 0.17 or -5/-28. You have to add like terms so 25x+2=53x-3 will turn to -28x=-5.
F and D is the answer
hope this helps
have a good day
