a) 35w+55-10w = 25w+55
28w+75-5w+12 = 23w +87
b) 25w+55 + 23w +87
=48w+142
they will be short by 2(24w+71)
c) 50w+25 = 25(2w+1)
answer: =98w+167

Answer:
14
Step-by-step explanation:
Given the data:
13 15 14 16 12
The point estimate of the population mean will be :
ΣX/ n
X = Given data points
N = sample size
ΣX = (13 + 15 + 14 + 16 + 12) = 70
N = 5
Hence,
ΣX/ N = 70 / 5
Point estimate of population mean = 14
Answer:
Correct expression: 85 + 0.06(t - 400)
Correct earnings: $91
Step-by-step explanation:
The expression Joan wrote is incorrect because instead, $85, she put $400 as her base salary. The correct expression would be 85 + 0.06(t - 400), where 85 is her base pay in dollars, and t - 400 represents her sales in dollars exceeding $400.
If Joan's sales were $500, she would not make $424.90, but
85 + 0.06(t - 400)
85 + 0.06(500 - 400)
85 + 0.06(100)
85 + 6
$91
Hope this helps.
