Step-by-step explanation:
Answer:
$1,562.50
Step-by-step explanation:
Markup= (selling price- cost)/cost
Let cost be represented by C
0.20 = (1875-C)/ C
0.20C = 1875 - C
0.20C+ C = 1875
1.20C=1875
Divide both sides by 1.20;
C= 1875/1.20
C= $1,562.50
The wholesale cost was $1,562.50
Answer:
Standard error = 0.070
Step-by-step explanation:
Formula for the standard error of the distribution of differences in sample proportions is;
σ_(A - B) = √((p_a^(1 - p_a^)/n_a) + (p_b^(1 - p_b^)/n_b))
We are given;
p_a^ = 0.48
n_a = 80
p_b^ = 0.13
n_b = 66
Thus;
σ_(A - B) = √((0.48(1 - 0.48)/80) + (0.14(1 - 0.13)/66))
σ_(A - B) = √0.00496545455
σ_(A - B) = 0.070
1) 2+12a
2) 8-5x
3)12-3z
i think those are the answers :)
